NGC 1232 in 60 Seconds

Narrator (April Hobart, CXC): Throughout the Universe, galaxies collide. Yet despite being a relatively common occurrence, astronomers are still trying to learn more about the details of what happens when these events take place. A new study using NASA's Chandra X-ray Observatory adds a new piece to this cosmic puzzle. The latest result from Chandra reveals a massive cloud of scorching gas in a galaxy about 60 million light years from Earth. The hot gas cloud - which has a temperature of about 6 million degrees -- is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232. If further research confirms that this indeed is the case, this discovery would mark the first time such a collision has been detected only in X-rays. And, because it might be an effective way to search for similar collisions, this result could have implications for understanding how other galaxies grow.
