Among its many effects, the U.S. government shutdown has created a struggling postdoctoral program, delays in NASA missions, and problems for government scientists trying to continue their research.
Astronomers can't agree on what kind of strange stellar death created a brilliant source dubbed "the Cow."
Electrostatic discharge in a simulated dusty Martian environment yields perchlorates — a potential energy source for microbial life — at abundances 1,000 times greater than sunlight alone.
Future missions to Saturn's moon Titan may have to contend with blowing particles and higher-than-expected winds from recently discovered dust storms.
Revised data changed expectations for a star pair that was supposed to merge in 2022.
The famed Arecibo Observatory has faced down several funding challenges in recent years, and a hurricane to boot, but now a new project is making the radio dish more relevant to astronomy than ever.
The Opportunity rover fell silent in June after nearly 15 years of work on the Red Planet. Now the dust storm that prevented its batteries from charging is clearing.
Faint echoes of light illuminate what really happened during the Great Eruption of the super-star Eta Carinae.
A new study says our neighbor galaxy’s big stellar halo and stellar evolution are due to a major collision that ended 2 billion years ago.
Scientists aren't comfortable yet saying that organics on Saturn's icy moon arose from life, but they have an idea of what to look for next.
New observations give more fuel to the concept of intermediate-mass black holes.
A recent experiment to better understand the nature of dark matter constrains a possible "fifth force" of nature to almost zero.
The gravitational-wave detection last year of a neutron star merger has revealed details on neutron star structure, ruling out exotic quark matter in the objects’ cores.
Hubble observations reveal a Jupiter-size exoplanet losing its atmosphere in a system 200 light-years away.
The Transiting Exoplanet Survey Satellite (TESS) launched successfully on April 18th at 6:51 p.m. EDT aboard a SpaceX Falcon 9 rocket to survey the entire sky for new worlds.
Astronomers have found the gamma-ray-emitting remains of three exploded stars, and the remnants might reveal the origin of cosmic rays.
