Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, chaotic clouds of debris shaped like cauliflowers. But supernova remnant Pa 30 looks

Four mice went to space as astronauts. One came back and became a mother. And that simple fact might matter more than you’d think for humanity’s future beyond Earth.

Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed planetary systems ever discovered. The TRAPPIST-1 system has captivated astronomers

Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have conducted a long-term photometric and spectroscopic study of a young stellar object known as V1180

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using

Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution

Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a “sterile” type of neutrino hypothesized to be responsible for

Using the Einstein Probe (EP), astronomers have detected a new X-ray transient event, which turned out to be an X-ray flare from the star PM J23221-0301 located about 150 light

Winds exceeding 110 mph that tore across the top of Mount Hamilton early Christmas morning blasted a massive steel protective door off the iconic white dome at Lick Observatory.
