There may be far fewer galaxies further out in the universe then might be expected, according to a new study led by Michigan State University.
Researchers from the National Astronomical Observatory of Japan, the University of Tokyo and other institutions have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in Hawai'i.
Observing time at the European Southern Observatory (ESO) on Paranal Mountain is a very precious commodity.
A NASA satellite controlled by Penn State University has detected a brief, super-bright, high-energy flare -- an X-ray nova -- erupting from a star system 8,000 light-years away from Earth named V404 Cygni.
Using the Subaru Telescope, researchers at the Special Astrophysical Observatory in Russia and Kyoto University in Japan have found evidence that enigmatic objects in nearby galaxies - called ultra-luminous X-ray sources (ULXs) - exhibit strong outflows that are created as matter falls onto their black holes at unexpectedly high rates.
New work from Carnegie's Alan Boss offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own solar system, as well as in others.
For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow.
At the time, the astronomers also looked back at archival data from optical telescopes over the twentieth century, finding two previous outbursts, one in 1938 and another one in 1956.
A new computer simulation tracking dark matter particles in the extreme gravity of a black hole shows that strong, potentially observable gamma-ray light can be produced.
A group of researchers from the Stony Brook University and the National Astronomical Observatory of Japan has discovered 854 "ultra dark galaxies" in the Coma Cluster by analyzing archival data from the Subaru Telescope.
Astronomers using NASA's Chandra X-ray Observatory have discovered the largest and brightest set of rings from X-ray light echoes ever observed.
Astronomers from Leiden University and the University of Arizona have successfully commissioned a new type of optic that can reveal the image of an exoplanet next to its parent star.
Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, the brightest objects in the universe.
Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun.
Astronomers have used the Hubble Space Telescope's infrared vision to uncover the mysterious early formative years of quasars, the brightest objects in the universe.
Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy's main spiral arm.
This new NASA/ESA Hubble Space Telescope image shows a gathering of four cosmic companions.
