NASA's Mars helicopter makes second flight

NASA successfully carried out a second flight on Mars on Thursday of its mini helicopter Ingenuity, a 52-second sortie that saw it climb to a height of 16 feet (five meters).

Ultra-high-energy gamma rays originate from pulsar nebulae

The discovery that the nebulae surrounding the most powerful pulsars are pumping out ultra-high-energy gamma rays could rewrite the book about the rays' galactic origins. Pulsars are rapidly rotating, highly magnetized collapsed ...

Catch comet R4 ATLAS as it nears Earth

Looking to do some springtime astronomy? With temperatures warming up in the northern hemisphere in April through May, galaxy season is upon us. At dusk, the area in the Bowl of Virgo asterism rising in the east is rife with ...

Bubble with titanium triggers titanic explosions

Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

Science without gravity at the International Space Station

In two decades orbiting the Earth the International Space Station has become a cutting-edge cosmic laboratory, with astronauts researching everything from black holes to disease and even gardening in microgravity.

Unusual binary system detected with LAMOST

Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have discovered an unusual binary system. The newly found binary, designated LAMOST J0140355+392651 (or J0140 for short), consists ...
