ACE? Rigel? NASA wants help naming manikin to fly around the moon.

A moonbound 'manikin' that will fly on a forthcoming NASA Artemis program mission needs a name — and the agency wants your help. Starting Wednesday (June 13), the "Name the Moonikin" competition began between eight names. Social media users on ...

NASA balloon detects California earthquake—next stop, Venus?

Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000 aftershocks over a six-week period. Seeing an opportunity, researchers from NASA's Jet Propulsion Laboratory and ...

Venus has a gooey flowing mantle jostling crust chunks on its surface

An international team of scientists used old radar images from NASA's Magellan mission, which ended operations in 2004, to study the Venusian surface. They found places where chunks of crust were sliding and turning like "pack ice," according to the ...

Venus may still be active based on 'pack ice' finding

(CNN) With its thick, toxic atmosphere and temperatures hot enough to melt lead, Venus seems like a dead planet. New research, however, suggests the planet could still be geologically active. And the kind of activity taking place on Venus could provide ...

Researchers trace dust grain's journey through newborn solar system

New research into the spreading of infections reveals need for greater collaboration between biology and physics

Researchers at the Niels Bohr Institute, University of Copenhagen, together with epidemiologist Lone Simonsen from Roskilde University form part of the panel advising the Danish government on how to tackle the different infection-spreading situations we ...

Major ocean-observing satellite starts providing science data

After six months of check-out and calibration in orbit, the Sentinel-6 Michael Freilich satellite will make its first two data streams available to the public on June 22. It launched from Vandenberg Air Force Base in California on Nov. 21, 2020, and is a ...
