Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left), similar to Jupiter’s moon Europa, or an icy world with a liquid substellar ocean and a cloudy atmosphere (center). LHS 1140 b is 1.7 times the size of Earth (right) and is the most promising exoplanet in the habitable zone found … Read more
On June 27, asteroid 2011 UL21 passed relatively close to Earth, flying past our planet at a distance of 6.6 million kilometers (4.1 million miles), which is about 17 times the average distance from Earth to the Moon. While it wasn’t close enough to worry about, the encounter gave astronomers a chance to get a … Read more
Laser light passing through the transparent crystal and exciting the thorium core.

This achievement would make it possible to replace today’s atomic clocks with … Read more
One of Britain’s most popular electric cars has a “potentially dangerous” problem that could put drivers and other road users at risk, according to a consumer watchdog. Product testing group Which? says it discovered the problem in the UK’s second best-selling electric car, the MG 4, during controlled and repeated tests the company carries out … Read more
Gold bounces off the psychologically important $2,300 level after a fresh selling phase. The pair remains under pressure from the longer-term outlook for interest rates – data from Friday could be key. XAU/USD is approaching the neckline for a possible top pattern. If this is broken, it could lead to a downward cascade. Gold (XAU/USD) … Read more
The Antarctic ice sheet is melting in a new, worrying way that scientific models used to project future sea level rise have not taken into account. This suggests that current projections could significantly underestimate the problem, according to a new study. Scientists from the British Antarctic Survey found that warm ocean water seeps under the … Read more
Standing on planet Earth, it’s easy to forget that we’re sitting on a rock hurtling through the solar system on a path that could potentially collide with other (smaller) space rocks, largely because we can’t feel that motion. If you ever have the urge to feel completely at the mercy of random space rocks, we … Read more
Gliese 12 b, which orbits a cool, red dwarf star just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In this artist’s concept, Gliese 12 b is depicted while maintaining a rarefied atmosphere. Credit: NASA/JPL-Caltech/R. Pain (Caltech-IPAC) Scientists have discovered Gliese 12 b, … Read more

Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research that used radar data from space to create an X-ray of the crucial glacier. As the salty, relatively warm ocean water meets the ice, it causes a “powerful melt” under the glacier and … Read more
