Andromeda Holds the Record of Most Black Holes Found in a Galaxy Other than Our Own Milky Way     Andromeda or M31 is one of the most famous galaxies in astronomy. It’s located 2.5 million light years away and it’s on a collision course with our galaxy the Milky Way. NASA’s Chandra observatory has been observing the universe in the x-ray wavelength and discovering black holes all across the universe. For the last 13 years with 152 observations Chandra has been able to add 26 new black holes to the previous 9 identified in Andromeda. Just think about that for a second. 35 total black holes. Each one of those black holes was caused by a star that was 5-10 times the mass of our Sun and collapsed into a black hole. Let’s take a closer look at Andromeda in x-ray vision.     This Chandra image shows 28 of the 35 black holes in Andromeda. Just seven...

Strange Brown Dwarf as Hot as Your Oven!     Astronomers gain interesting insight on these failed stars or brown dwarf stars. Brown dwarf stars are essentially star like bodies that have a mass larger than a planet but too small to trigger nuclear fusion and ignite into a full fledged star. These stars are born with very little heat and can produce temperatures from 260 to 350 degrees Fahrenheit (125 and 175 degrees Celsius). Their mass can be anywhere from 5 to 20 times the size of Jupiter. Scientists have even discovered a brown dwarf star so cold that even the human body temperature is warmer. However, since they are cold and small it prompts a difficult task to astronomers to accurately measure how dim, big, and far away these stars are. Using NASA’s Spitzer Space Telescope scientists have been able to discover 8 brown dwarfs with precise distances. This helped them...
