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
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.
While scanning the sky for the oldest cosmic light, ESA’s Planck satellite captured snapshots of some of the largest objects populating the Universe today: galaxy clusters and superclusters.
It hardly gets any bigger than this: A massive galaxy cluster is visible in this image captured by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3.
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 from the University of Sydney say that a supermassive black hole situated in the heart of our galaxy erupted with such force about two million years ago that it illuminated a cloud located 200,000 light years away.
Two groups of astronomers teamed up creating the finest 3D map of the Milky Way galaxy with the help of ESO (European Southern Observatory) telescopes and discovered that its inner-region has a peanut-like shape or X-shape at the heart when viewed from some angles.
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.
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.
Observations with NASA's Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth.
An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the universe from its FastSound project, which is surveying galaxies in the universe over nine billion light-years away.
The Subaru Telescope has captured a stunning new image of the Andromeda Galaxy using its new instrument. The image reveals the capabilities of the telescope's Hyper Suprime-Cam (HSC), which could provide more information in the future about nearby galaxies and stars.
