Veil of fiery gas revealed around the disk of Milky Way

Scientists may have finally hit upon the possible mysterious sources that have pumped heat and kept alive the fiery hot gas that has recently been detected surrounding the Milky Way but has so far remained unexplained.

Ring around Tabby's star

This illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian's Star or Tabby's Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler ...

Video: Our sun is the star in a new simulation

NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers ...

Hubble finds sizzling details about young star FU Orionis

In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than ...

A nearby supernova could end the search for dark matter

The search for the universe's dark matter could end tomorrow—given a nearby supernova and a little luck. The nature of dark matter has eluded astronomers for 90 years, since the realization that 85% of the matter in the ...

Introducing 'UFO' galaxies—the Milky Way's dustier cousins

In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red ...

Chandra and Hubble tune into 'flame-throwing' Guitar Nebula

Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's ...

New millisecond pulsar discovered

Using the Green Bank Telescope (GBT), astronomers have observed a globular cluster known as Terzan 6. They detected a new millisecond pulsar that is likely associated with this cluster. The finding was reported in a research ...

NASA's Chandra finds galaxy cluster that crosses the streams

Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure.
