'Ultrahot Neptune' discovered around sunlike star

Astronomers have discovered a new type of alien world — the first known "ultrahot Neptune," a giant planet that orbits its star 60 times closer than Earth does the sun, a new study finds. Previous research found that about 1 in 200 sunlike stars possesses a ...

Strange bright rocks reveal glimpse of asteroid Ryugu's violent past

Shiny boulders on one of the darkest asteroids in the solar system may shed light on the cataclysmic impacts behind that space rock's origins, a new study finds. The near-Earth asteroids Itokawa, Bennu and Ryugu are each loose piles of rubble held together ...

Meet Calypso, a daredevil mission concept to explore the surface of Venus

Of all the rocky, inner worlds of the solar system, Venus is the most challenging to explore. With surface temperatures reaching a bewildering 867 degrees Fahrenheit (464 degrees Celsius), even the most hardened landers can't survive for long. But a new ...

Saturn's ocean moon Enceladus has fresh ice in unexpected place

Saturn's geyser-spewing moon Enceladus may be even more active than scientists had thought. Fresh images created using data from NASA's dead Cassini spacecraft show that Enceladus' northern hemisphere was resurfaced with ice relatively recently.

Covid: 'Broken' doctor speaks out against conspiracies

A junior doctor has spoken out at coronavirus conspiracy theories after being accused of faking a photograph following an operation in full PPE. Ceri Hayles took the picture after a surgery at the Princess of Wales Hospital in Bridgend, her face showing the ...

Researchers identify new type of superconductor

Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, Cornell researchers—led by Brad Ramshaw, the Dick & Dale Reis Johnson Assistant Professor in the College of Arts and Sciences—have discovered a ...

Arctic sea-ice shrinks to near record low extent

This summer's Arctic sea-ice shrank to its second lowest ever extent in the era of satellite observation. The floes withdrew to just under 3.74 million sq km (1.44 million sq miles) last week, preliminary data indicates. The only time this minimum has been beaten ...

'A Climate Emergency Unfolding Before Our Eyes.' Arctic Sea Ice Has Shrunk to Almost Historic Levels

From the bridge of the Arctic Sunrise, an old ice-breaking fishing trawler turned research vessel now plying the polar waters between Greenland and northern Norway, Laura Meller has an unparalleled view of our planet's future. It is both gorgeous, and ...

Astronomers discover an Earth-sized 'pi planet' with a 3.14-day orbit

In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a "pi Earth"—an Earth-sized planet that zips around its star every 3.14 days, in an orbit reminiscent of the universal mathematics constant.

Rosetta spacecraft detects unexpected ultraviolet aurora at a comet

Data from Southwest Research Institute-led instruments aboard ESA's Rosetta spacecraft helped reveal unique ultraviolet auroral emissions around irregularly shaped Comet 67P. Although these auroras are outside the visible spectra, other auroras have ...
