This totally stunning composite picture depicts the Small Magellanic Cloud, one of the Milky Way's closest galactic neighbors. Astronomers recently announced that they'd managed to detect X-rays coming from the young stars, of similar size to Earth, in the SMC's "Wing."
Here you can see an extremely rare video that shows a neutron star in the process of doing exactly what these super-violent pulsars do best: shoot a jet of particles out at an extremely high speed.
Check out the insane scale of this artist's representation of the Milky Way Galaxy, looking tiny and insignificant in the middle of a huge ball of hot gas. The image shows the hot gas extending with a radius of 300,000 light years — but NASA says it may "extend significantly further."
160,000 light years away, in the Large Magellanic Cloud, an object is being expelled from the remnant of a supernova at 500 million miles an hour. And NASA got this shot of it.
Can a single galaxy support two mid-sized black holes? This one does. This composite image shows the starburst galaxy M82, with two intermediate-sized "survivor" black holes that have managed to avoid falling into the galactic core.
It was the 400th anniversary of Galileo's first telescopic view of the heavens the other day, and NASA unveiled this incredible panoramic view of the center of our galaxy. It's a composite of images from all of NASA's great observatories.
