A Tour of SDSS J103842.59+484917.7
One hundred years ago this month, Albert Einstein published his theory of general relativity, one of the most important scientific achievements in the last century. (2015-11-24)

M84 in 60 Seconds

Narrator (Megan Watzke, CXC): M84 is a massive elliptical galaxy located about 55 million light years from Earth in the Virgo Cluster. This composite image is made from X-rays from Chandra, which are colored blue, and radio emission from the Very Large Array that is seen as red. The interesting thing about this image is that astronomers can trace a number of bubbles generated by particles moving at nearly the speed of light. These particles are propelled by the supermassive black hole at the center of the galaxy in the form of a two-sided jet. By studying objects like M84, astronomers hope to better understand how black holes influence the environments that surround them.
