A new composite image of NGC 2207 and IC 2163 contains X-rays from Chandra X-Ray Observatory. Two colliding galaxies in the Canis Major constellation put on an impressive light display that was captured in a composite image using data from NASA’s Chandra X-ray Observatory. The galaxies, named NGC 2207 and IC 2163, were “caught in a grazing encounter,” NASA said in a statement. The two have hosted... 

The bright spot at the center of this large elliptical galaxy is one of the biggest black holes in the universe, which scientists recently found is even bigger than previously thought. This galaxy is in the center of the galaxy cluster PKS 0745-19, which is located about 1.3 billion light years from Earth It turns out that the largest black holes may be even bigger than scientists previously thought.... 

The handout illustration provided by NASA shows Phoenix, the newly-found galaxy. Astronomers have recently discovered a distant gigantic galaxy cluster that is capable of giving birth to new stars at an extraordinary rate. Observations from NASA’s Chandra X-ray Observatory, the US National Science Foundation’s South Pole Telescope and eight other observatories, showed that the newly-discovered... 

Click to enlarge This photo shows the Antenna galaxies, which started colliding 100 million years ago, creating millions of stars in the process which later exploded as supernovas. I really find it hard and sad to know that I’ll never see this live. But at least we have the telescopes to see it from here. The image of the galaxy—which is located 62 million light-years away from Earth—was...
