Why Astronomers Do not Report UFOs

Filed under: Astronomy Report — Tags: , — admin @ 8:15 pm

Phil Plait, from Blogs.discovermagazine.com, posted an article today explaining why Astronomers, the individuals who spend their days seeking up at the stars, do not ever report seeing UFOs. Even though it’s a excellent question, I discovered the answer to be insulting and narrow-minded. Yes, yes I know that you’ll find those individuals who can confuse the Moon or an airplane for an alien spacecraft, but what about those of us who have seen strange lights being chased off by incoming jets?

When I was a kid in the 80s, we lived in Orange County (Garden Grove, CA). One evening, as my siblings and I were helping our mother unload groceries from the car, my sister yelled “What’s that?” and pointed up. I kid you not; we all stood there watching this upright triangle object with a multicolor light emanating from it, float via the horizon. A number of seconds later, two military jets appeared (from the south?) and the triangular object rapidly changed course and took a incredibly fast acceleration upwards into the clouds. And just like that, it vanished. We stood there watching the jets, slowly climb up in altitude. Nowhere near the speed in which the object did. The truth from the matter is that astronomers devote their time searching at fixated objects thousands of miles away. We (earthly citizens) occasionally glance upwards and can only see a number of miles up. If you will discover other lifeforms visiting us, they would be observing closely to the Earth’s surface. Way out with the sight of an astronomer’s telescope.

Contrary to what Mr. Plait’s post states, there have been plenty of reports given to MUFON from amateur and professional astronomers. Checking the MUFON database, you’ll find several listed. A single that stands out occurred last October. MUFON case # 20,023. This occurred in Oklahoma.

On the evening of 10-17-09 myself and four other club members were at our astronomy clubs’ observatory (35.8308 96.14518) for a clear night of observing. With many years of experience in observing under our belts we were needless to say quite qualified to identify most anything that we would see. Between approximately 6:40 – 7:00 P.M.

One of the members noticed something off in the west and queried as to what it may happen to be. First and foremost it was bright, more or less as bright as Jupiter, yet setting about ten to twelve degrees above the horizon, due west. At our first sighting most of us thought that it was nothing more than an airliner reflecting sunlight from the setting sun but that determination was tossed aside shortly there after. If it had been what we first thought it was it would’ve lost it’s size and brightness fairly quick as it shifted positions in relation to the sun while in flight. But, it continued to maintain its position, did not move in any direction – vertically, horizontally.

If by some chance it were a celestial body it would follow a gradual celestial track that all of us would have noticed in a few minutes. Again, it didn’t move, remained in one position, which eliminated the possibility of it being a celestial body that none of us were unlikely familiar with. That alone became puzzling since the obvious – Venus, Mercury – are now tracking in the morning eastern sky, not the evening western sky. With that we continued to watch it as one of the guys used his 10×50 binoculars to get a better view. What was seen initially brought to mind that it may perhaps be a high altitude research balloon but the more we watched it and as it maintained its position that thought was tossed quickly also. From the beginning it remained in one position, never moved. Balloons, of any type, will not remain in one specific position be they weather balloons, high altitude research balloons or otherwise.
But as we watched it more closely it was very surprising as to the manner in which it morphed into various shapes and sizes. Its brightness would vary some but that was easily seen as being caused by the low-lying clouds on the horizon. As we commonly call it – it was “sitting in the soup”. When they would move in front of it the objects brightness would dim some. Otherwise it would maintain its brightness. That was easily seen via binocular observations. The longer we watched it the more curious we all became and with that growing curiosity we quickly set two telescopes onto it. Two different sized telescopes were used, one, Celestron 11” Schimdt-Cassegrain telescope and a smaller Orion 4.5” dobsonian telescope. Between the two we could pull it in for a much closer look in a very inquisitive effort to determine just what it actually was. Charts and web sites were checked also to make sure we weren’t simply forgetting perhaps one event that may explain what we were now seeing. Nothing could be found. The Celestron was using a 40mm eyepiece for a much wider field of view whereas the smaller Orion had a 15mm eyepiece to pull it in much closer. Through the Orion one could easily see what appeared right off as a bell shape.

The same was viewed in the other also. But as mentioned before it morphed into what was clearly seen and could be interpreted as the same basic outline of the Shuttle that anyone would see as it flies over. Again, the same basic shape as to what you would see looking up at the bottom of it. That distinctive shape was easily recognized. At the rear of it you could see what looked like bluish green waves that would both come and go from the main rear line of the object. Nowhere else was this color and wave seen, just at the rear. The objects color was a combination of the just mentioned bluish green at the rear to a lighter orange yellow up through the main body and then into red orange, much more intense, than any of the other colors at the top or perhaps, from appearance at that time, leading edge. None of us had ever seen a color distribution of this sort before. Especially on either the Shuttle or any other normal day-to-day satellites. From our position/location it appeared to be hovering over either Bristow, Ok or possibly even Oklahoma City. There was no attempt by any of us then to determine its specific distance or altitude from us. The same applies to its actual size. Visually, it appeared very similar to the size of Jupiter. Other than that comparison we honestly don’t know either its distance or specific altitude. It remained in the same position for approximately 40 minutes and never moved. Close to 8 P.M. we started to notice what appeared to be a ring of lights that was rotating around the bottom portion.

The lights were seen in the same location that the bluish green colored waves were at. Several of us noticed this while looking at it through the telescopes. Needless to say this was surprising to us all. This carried on for one to two minutes and then suddenly the object started to move. The movement was slow at the beginning but increased very rapidly. I had my eye glued to the 40mm eyepiece when this began and once it started I could not move. Within two seconds it had totally disappeared from open visual sight but I still had a lock on it in the eyepiece. Fast, very fast it moved from dead center in the eyepiece field of view upwards and at the same time was getting smaller and smaller as it flew away. Two or three seconds later it was totally gone from view in either of the telescopes. The speed that it moved was without question way beyond anything that we have knowledge of or is publicly known to be in our military. At the rate it flew away would make a SR-71 Blackbird look very old and slow. Could it have possibly been a new experimental aircraft? Possibly yes but if so what was something such as that doing in Oklahoma? Most generally new experimental, top-secret aircraft of that type are being tested at either Edwards AFB or Area 51, not Oklahoma. In a nutshell, we will never know.
It was unidentifiable, it was in the air and flew away and it most certainly was an object of some unknown kind/type. From this alone it could be justifiably categorized as a UFO.

Newly Found Solar System

Filed under: Astronomy Report — Tags: — admin @ 12:54 pm

solar system

This is cool stuff, astronomers employing the ESO HARPS instrument have discovered a planetary system with at the very least 5 planets and possibly a couple far more all around a Sun-like star. The star is called HD10180 and is situated 127 light-years away within the constellation Hydrus.

Here’s the press release from the ESO:

“We have uncovered what is most likely the method with the most planets yet found out,” says Christophe Lovis, lead author from the paper reporting the result. “This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary methods and not just of individual planets. Studies of planetary motions inside new process reveal complicated gravitational interactions involving the planets and give us insights into the long-term evolution with the system.”

The team of astronomers employed the HARPS spectrograph, attached to ESO’s 3.6-metre telescope at La Silla, Chile, for a six-year-long study in the Sun-like star HD 10180, located 127 light-years away inside southern constellation of Hydrus (the Male Water Snake). HARPS is an instrument with unrivalled measurement stability and good precision and is the world’s most successful exoplanet hunter.

Thanks to the 190 individual HARPS measurements, the astronomers detected the tiny back and forth motions from the star caused by the complex gravitational attractions from five or a lot more planets. The five strongest signals correspond to planets with Neptune-like masses — concerning 13 and 25 Earth masses which orbit the star with periods ranging from about 6 to 600 days. These planets are situated concerning .06 and 1.4 times the Earth–Sun distance from their central star.

“We also have great reasons to believe that two other planets are present, says Lovis. A single would be a Saturn-like planet (with a minimum mass of 65 Earth masses) orbiting in 22Ǡ days. The other could well be the least massive exoplanet ever discovered, using a mass of about 1.4 times that with the Earth. It’s extremely close to its host star, at just 2 percent in the Earth–Sun distance. 1 “yearâ on this planet would last only 1.18 Earth-days.

â€This object causes a wobble of its star of only about three km/hour— slower than walking speed — and this motion is very difficult to measure,” says team member Damien Ségransan. If confirmed, this object will be another example of a hot rocky planet, similar to Corot-7b (a href=”http://www.eso.org/public/news/eso0933/>eso0933).

The newly discovered method of planets around HD 10180 is distinctive in a number of respects. Very first of all, with no less than 5 Neptune-like planets lying within a distance equivalent towards the orbit of Mars, this method is a lot more populated than our Solar Program in its inner region, and has many more massive planets there. Furthermore, the program probably has no Jupiter-like gas giant. Additionally, all the planets appear to have practically circular orbits.

So far, astronomers know of fifteen devices with at the least three planets. The last record-holder was 55 Cancri, which contains five planets, two of them being giant planets. “Systems of low-mass planets like the one approximately HD 񷫄 appear to be very typical, but their formation history remains a puzzle,” says Lovis.

Utilizing the new discovery as well as data for other planetary devices, the astronomers observed an equivalent from the Titius–Bode law that exists in our Solar Technique: the distances in the planets from their star seem to follow a regular pattern. “This could be a signature with the formation process of these planetary methods,” says team member Michel Mayor.

A different important result found by the astronomers whilst studying these systems is that there is a relationship involving the mass of a planetary system and also the mass and chemical content of its host star. All very massive planetary programs are uncovered around massive and metal-rich stars, though the four lowest-mass techniques are uncovered around lower-mass and metal-poor stars. Such properties confirm current theoretical models.

The discovery is announced these days at the international colloquium “Detection and dynamics of transiting exoplanets, at the Observatoire de Haute-Provence, France.

Jupiter Impact

Filed under: Astronomy Report — Tags: — admin @ 12:36 pm

Jupiter has had an additional impact as you are able to see in the video, this one on August 20th.  Challenging to say what the impacting body was.  There weren’t any black plumes so it could be the density/mass wasn’t like the Shoemaker-Levy 9 comet (D/1993 F2) of 1994. Then once more trajectory and velocity wants to be figured in, still it’s likely smaller.  Probably an object captured by Jupiter’s gravity, a moon of sorts, falling into the planet.  Not at all far fetched; an object ventures as well close towards the massive planet, gets captured into an orbit but doesn’t have sufficient velocity to keep it from spiraling to its demise.  From our perspective the object would lack the punch to accomplish very much a lot more than end its life in a flash.

It’s probably we will see far more impacts like these thanks to dedicated observers like amateur astronomer Mr. Masayuki Tachikawa the gentleman who captured the video.

What is a Black Hole?

Filed under: Astronomy Report — Tags: , — admin @ 3:01 pm

A black hole is a mystery that has managed to confound and perplex researchers. It has the ability to swallow significant stars. Several compare a black hole to a vacuum cleaner that sucks up all of the dirt and litter within it. Although loads of investigation has been carried out on black holes, probably the most accept concept that explains these mysterious holes is the one particular given by Albert Einstein via his General Concept of Relativity.

The theory states that a hole is an region or body located in space that won’t permit something to pass as a result of it, not even lumination. Researchers realize that worm holes are produced from large stars that die and when lumination enters them, the holes have such strong gravity that they trap the lumination within them.

In order for a superstar to grow to be a worm hole, it will must be really huge in sizing. It’s going to need to be a minimum of fifteen larger than the Sun. When a star of this size dies, the hydrogen approximately the superstar is pulled within and this causes the superstar to collapse under its personal gravity. This causes the star to turn out to be smaller in sizing. Even so, though the star’s size is reducing, the opposite happens to its gravity. It keeps increasing. The cause that this star is known as black hole is because this dead star will not reflect any form of light, and it especially won’t permit passage of light.

Researchers are still trying to discern what a hole is created up of. Although they realize that stars have constant nuclear fission, when they die, this fission comes to an end. So, it truly is pretty feasible that black holes are made up of neutrons. The outer surface of the black hole is identified as event horizon. If anything is trapped in the outer surface, it will eventually have to have a velocity that is certainly greater than light’s velocity to escape. Even so, this isn’t probable.

A hole is just not something that is visible. Nonetheless, as the hole gives out X-rays, we can detect a position of a black hole by detecting the X-rays. Till date, scientists have discovered fourteen holes, along with the a single closest to Earth is called V 4641. It truly is all-around 1,600 lighting many years from Earth. The second closest black hole is known as Cygnus X-1, which is approximately 8,000 light many years from Earth.

Some of the Popular Moons of Jupiter

Filed under: Astronomy Report — Tags: , , — admin @ 1:57 pm

Jupiter will be the biggest earth in the Solar Program. It can be located all-around 500 million miles from the Sun, and its atmosphere is produced up of 90 % of hydrogen, 10 % of helium and small bit of methane and ammonia. Besides the sun, Jupiter also emits heat into our Solar Technique.

Essentially the most interesting part about Jupiter is its several moons. According to astronomers, the planet has much more than 63 moons, but the most common are Sinope, Ganymede, Metis, Thebe and Europa. Four on the moons with the world were discovered by Galileo in 1610. He named these moons Europa, Callisto, Io and Ganymede. At times, these four moons are also recognized as Galilean moons.

Ganymede: This moon of Jupiter got is name from Greek mythology where Ganymede was the cup bearer. Ganymede would be the biggest of all of the moons of the world and it is also the greatest moon in our Solar Process. It can be bigger in size than Mercury and Mars. This moon was named by Simon Marius, who was an astronomer. It truly is considered that the surface of Ganymede is manufactured up of ice and water. Even though it is believed that Ganymede does not have any atmosphere, recent discovery shows presence of ozone.

Europa: In Greek mythology, the Phoenician princess who managed to mesmerize Zeus was named Europa. This moon of Jupiter has characteristic red cracks criss-crossing its surface. It will be the 4th biggest moon with the world. It truly is believed that Europa has water, and hence, it’s capable of sustaining life.

Io: Named soon after the woman who Jupiter, the Greek god, had fallen in love with. This moon would be the third major of all of the moons that Jupiter has. Io is residence to various volcanoes, that are active and responsible for releasing sulfuric acid.

Callisto: This would be the second major moon of Jupiter and called after the nymph who bewitched Zeus. Callisto is similar in size to Mercury, also it is considered that its crust aboutń billion years old.

Astronomers and astrophysicists are still attempting to discover additional moons all-around Jupiter, also it is rather probable that we will be hearing additional about this earth with numerous moons inside the near future.

I am having a difficult time figuring out how you can write this post without having seeming bitter. It’s difficult to watch a thing that this nation has performed together and completed well, to be thrown away like yesterday’s garbage. Something individuals have died performing, not because they had to accomplish it but due to the fact they were driven to be the greatest and wanted the country be the ideal.

Ah, that doesn’t matter anymore. I hope everybody joins me in supporting the exclusive business in human spaceflight. Given the chance, private marketplace will be effective. I’m fairly pessimistic I suppose, simply because I’m afraid the first time a thing goes wrong, the government will take a fast break from passing unread, untitled mega-spending bills like they are carrying out some great stroke of company, to shut the exclusive market down too. Don’t believe it? What’s heading on or rather not heading on within the Gulf?

Since the days of Apollo there have been crew wake up songs. Inside a poignant end to the US Human spaceflight program, NASA is running a contest to select the final wakeup songs for the last two shuttle missions. To the STS-133 mission you are able to decide on from a list of previous songs and for your STS-134 mission you’ll be able to send in the song YOU wrote. Entries for the STS-134 mission will be screened and the finalists is going to be put on a list for us to vote on – I can’t wait to hear them.

AMPERE

Filed under: Astronomy Report — Tags: , , — admin @ 4:46 pm

We’ve heard the warnings about room weather. You might be tempted to think “big offer I haven’t ever had a dilemma before”. The truth is not so numerous years ago it wasn’t that major of a deal, the worst the typical individual on the ground might see was a energy failure as voltages in the overhead power lines spiked and possibly caused complications. I have heard stories from aircraft crews particularly the older ones those flying over the poles, the flights didn’t sound like fun.

These days additionally, we are so dependent on satellites a huge storm would lead to havoc. If actions aren’t taken to safeguard the satellites they could possibly be damaged beyond repair. We have all sorts of techniques to monitor the sun to see solar activity and that is a massive aid.

Still, how the Earth’s area environment responds to storms is key to developing trustworthy monitoring and forecasting and that effort has just produced a huge step forward.

The National Science Foundation, Johns Hopkins Applied Physics Lab, Boeing and Iridium Communications have implemented a new space-based program: Active Magnetosphere and Planetary Electrodynamics Response Experiment, also identified as AMPERE.

Meet Mars, the Red Planet

Filed under: Astronomy Report — Tags: , , , — admin @ 3:07 pm

On some nights, you may perhaps see a bright light in the sky, one that looks like a star with a reddish gleam. For a matter of truth, that may be the red planet, 1 named after the Roman god of war – Mars. This globe will be the fourth from the sun, at about 228 million kilometers away.

In the event you were to see an image from the globe, you would believe that parts of it looked like the moon. Unlike the quiet moon, the atmosphere of what’s Mars produced of are numerous gases, that are mainly carbon dioxide, nitrogen, and argon, appearing like thin blue and white clouds moving across its sky. With fierce windstorms, the sand whirls up through the plains, filling the air with dust. This orange-colored dust that fills its skies is what you see from afar.

The size of Mars is only about half the sizing of Earth. As this is so, one particular year on Mars is practically half the year on Earth, while the day is virtually the identical as ours. The tilt in the planet’s axis is equivalent to our globe, which makes the seasons there equivalent to ours. Yet, due to its sizing, the seasons last nearly twice as prolonged. There are also excellent fluctuations in temperature in between the day and night.

Volcanoes will also be common on Mars, but as compared towards ones on Earth, these volcanoes are a lot higher and they stretch a lot wider than Mount Everest, the highest mountain on Earth. The size distinction occurs because on Mars, there is really a lack in tectonic plates. This enables the volcano activity to persist longer on exactly the same spot, allowing the volcano much more time to grow. Also, the surface gravity for the earth is only one third of Earth’s, so the growth just isn’t pulled down for the center of gravity just as much. The atmosphere there is certainly also not as erosive, so the surface with the volcanoes is just not damaged as a great deal.

There are also canyons on the earth. A single canyon from this planet is as wide as the entire continent of North America. It is believed to be brought about by catastrophic outbursts of water, ice, and debris from underground. There are also extensive, winding marks that look like dry river valleys, believed being induced by rainfall extended ago when the temperature was warm enough for water to exist.

There have been speculations by scientists, claiming the possibilities of Earthlings living on Mars. Would you would like to live there, having recognized what’s Mars made of?
