Hubble Space Telescope astronomers are finding that the old adage, “What goes up, must come down” even applies to an immense cloud of hydrogen gas outside our Milky Way…

Since astronomers discovered the Smith Cloud, a giant gas cloud plummeting toward the Milky Way, they have been unable to determine its composition, which would hold clues as to its origin. Astronomers have now determined that the cloud contains elements similar to our sun, which means the cloud originated in the Milky Way’s outer edges…

The graph made astronomer Tabetha “Tabby” Boyajian sit up at her desk at Yale University. Something was definitely strange — the line was mostly flat but had two sharp dips resembling stalactites hanging from the ceiling of a cave. The dips implied that light coming from the star KIC 8462852, more than 1,400 light years away,…

Astronomers in China working with one of world’s largest optical telescopes released a huge collection of data over the new year holiday, increasing the chances of “significant findings” in space exploration, experts say. The latest update to the National Astronomical Observatories’ sky survey, conducted using the LAMOST telescope, includes some 4.62 million spectral data relating…
