Magnificent Spiral Galaxy NGC 4921 to Help Determining Expansion Rate of Universe

The magnificent spiral NGC 4921 has been informally dubbed anemic because of its low rate of star formation and low surface brightness. Visible in the above image are, from the center, a bright nucleus, a bright central bar, a prominent ring of dark dust, blue clusters of recently formed stars

Surprisingly Early Cosmic 'Seeding' of Life's Elements Driven by Supernovae and Blackholes

Most of the universe's heavy elements, including the iron central to life itself, formed surprisingly early in cosmic history and somehow spread evenly throughout the universe, according to a new study of the Perseus Galaxy Cluster using Japan's Suzaku satellite.

Scientists Start to Simulate Whole Galaxies and the Universe With Supercomputers

The universe is a vast and mysterious place, but we are beginning to understand it better thanks to some powerful technology. Scientists around the world are using supercomputers to simulate how the big bang led to the formation of galaxies, such as our own Milky Way.

Astronomers Map the Peanut in the Center of the Milky Way Galaxy (Video)

Astronomers have used data from ESO telescopes to make the best three-dimensional map yet of the central parts of the Milky Way. It turns out that the inner regions, surprisingly, look a bit like a peanut.

Giant Black Hole at Galactic Core is Peaceful, Devours Only 1% of Captured Matter

New Chandra images of Sagittarius A* (Sgr A*), which is located about 26,000 light-years from Earth, indicate that less than 1 percent of the gas initially within Sgr A*'s gravitational grasp ever reaches the point of no return, also called the event horizon.
