 Milky Way’s Supermassive Black Hole is “Eating” Asteroids According to a New Study - February 9, 2012. Astronomers have been seeing bright x-ray flares around the black hole with the Chandra X-ray Observatory since 1999 and the flares have also been seen in the infrared wavelengths with the European Southern Observatory’s Very Large Telescope in Chile. A team of astronomers now believes that these flares may be the result of asteroids being thrown into the black hole’s accretion disk.

UFO Seen Over City in Poland

A news report appearing on the Examiner.com website on January 27, 2012 says that on Wednesday, January 25, 2012 a blinking orange colored light was seen up in the sky over Tarnow, a city located in the southwest part of Poland. According to the news report, several witnesses saw the UFO “flying high above the nearly deserted city streets on a dark and starless night.” There was no mention as to what time exactly that the UFO appeared in the sky and for how long it was seen or if it did anything really unusual except that it flew a little erratically. The report did say that there were no strange sounds associated with the UFO as have been with other UFO sightings recently. One witnesses did take a video of the object which may be seen at the following website: http://www.youtube.com/user/Rasiek. The top three images on the website show the bright, orange light in the dark sky over the town. Having a video of the object will obviously offer some proof or evidence that something unusual was up in the sky.

 

What is the Lunar and Planetary Institute?

According to their mission statement, the Lunar and Planetary Institute which is located in Houston, Texas is a division of the Universities Space Research Association (USRA) and conducts research in planetary science that “supports the National Aeronautics and Space Administration’s (NASA) efforts to explore the solar system.”

More specifically, the Institute “serves as a scientific forum attracting world-class visiting scientists, postdoctoral fellows, students, and resident experts.” It “supports and serves the research community through newsletters, meetings, and other activities.” It also “collects and disseminates planetary data and engages, excites, and educates the public about space science.”

The Institute maintains a website on the internet which covers the latest news in planetary exploration and lists its various activities, meetings, etc. To learn more about this Institute, go online at: http://www.lpi.usra.edu/
