Scientists detect five supernovae that never been seen before
Stars are exploding in dusty galaxies. We just can't always see them.
Exploding stars generate dramatic light shows. Infrared telescopes like Spitzer can see through...
Scientists find likely locations of the early molten Moon’s deep secrets
Shortly after it formed, the Moon was covered in a global ocean of molten rock (magma).
As the magma ocean cooled and solidified, dense minerals...
Mars’ bright south pole reflections may be clay, not water, shows study
Bright reflections observed at Mars’ south pole serve as evidence for water. But, seeing may be deceiving.
After measuring the area’s electrical properties with orbiting,...
Clays, not water, are likely source of Mars lakes
Three studies published in the past month have cast doubt on the premise of subsurface lakes below the Martian south pole.
Where there’s water, there’s...
Scientists discover unusual cool flames aboard International Space Station
An entirely new class of fire, spherical cool diffusion flames, or simply "cool flames," has been documented aboard the International Space Station.
The discovery of these...
Why is this weird, metallic star hurtling out of the Milky Way
About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way.
This particular star, known as LP 40−365,...
Scientists detect gas re-accretion in dying galaxies for the first time
Previously displaced gases can re-accrete onto galaxies, potentially slowing down the process of galaxy death caused by ram pressure stripping, and creating unique structures...
Scientists detect the light from behind a black hole for the first time
Researchers observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole.
Watching X-rays flung out into the universe by the...
Scientists show how planets form in binary systems without getting crushed
Astronomers have developed the most realistic model to date of planet formation in binary star systems.
The researchers, from the University of Cambridge and the...
Scientists find first evidence of water vapor at Jupiter’s moon Ganymede
For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.
This water vapor forms when ice from...
