A new map of the universe - based on observations of 1.2 million galaxies - confirms cosmologists' theories about the web of galaxies making up our universe as a whole.
Peering deeper into the Orion Nebula than ever before, astronomers have found a plethora of low-mass objects, some isolated "planets" and some brown dwarfs.
The object labeled RR245 is traveling toward its closest approach to our sun. It'll reach this (very distant) closest point - 3 billion miles, or 5 billion km - around 2096.
The survey shows 250,000 galaxies in an area of sky 4 times the size of a full moon. It'll be used to help trace galaxy evolution over the last 13 billion years.
A jet of swirling, cool, dense gas in the center of a galaxy - 70 million light-years from Earth - gives new clues to how supermassive black holes grow.
