NASA’s Kepler Space Telescope, which spent nine years in deep space collecting data that detected thousands of exoplanets, has run out of fuel needed...
Astronomers using CSIRO’s Australian SKA Pathfinder (ASKAP) telescope has discovered that a nearby dwarf galaxy called the Small Magellanic Cloud has...
Astronomers using NASA’s Chandra X-ray Observatory have confirmed that a supernova remnant called Kes 75 contains the youngest known pulsar in our Milky...
Astronomers have detected gamma rays coming from the outermost regions of an unusual star system within our Milky Way Galaxy. The source is a microquasar...
Astronomers using data from ESA’s star mapping Gaia mission to look for hypervelocity stars being kicked out of our Milky Way Galaxy were surprised to...
Astronomers analyzing data from the second release of ESA’s star mapping mission Gaia have shown that our Milky Way Galaxy is still enduring the effects...
The Large Magellanic Cloud, a dwarf galaxy located about 160,000 light-years away, has a counter-rotating stellar population in its disk. In a new paper...
Astronomers have largely assumed that water-world exoplanets would not support the cycling of minerals and gases that keeps the climate stable on Earth,...
A team of astronomers from the United States and the United Kingdom has found evidence that Milky Way’s faintest satellites — including dwarf galaxies...
A research team led by Harvard University astronomer Li Zeng has shown that water is likely to be a major component of extrasolar planets which are between...
Close encounters between stars in Omega Centauri, the only star cluster visible to the naked eye, leave little room for habitable planets, according to...
