How to keep spacesuit ‘underwear’ clean?
Spacewalking is a major highlight of any astronaut’s career. But there is a downside: putting on your spacesuit means sharing some previously-worn underlayers. A new ESA study is looking into how best to keep these items clean and hygienic as humans venture on to the Moon and beyond.
Ingenuity Mars Helicopter Completes First One-Way Trip
NASA's Ingenuity Mars Helicopter completed its fifth flight on the Red Planet today with its first one-way journey from Wright Brothers Field to an airfield 423 feet (129 meters) to the south....
Perseverance's Robotic Arm Starts Conducting Science
NASA's Perseverance rover has been busy serving as a communications base station for the Ingenuity Mars Helicopter and documenting the rotorcraft's historic flights. But the rover has also been busy focusing its science instruments on rocks that lay on the...
New Marine Sulfur Cycle Model After The Snowball Earth Glaciation
The Sturtian Snowball Earth glaciation (717~660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice sheets extended to low latitudes, and model simulations suggest global frozen ocean as well...
Using DNA To Trace The Origins Of Giant Viruses
2003 was a big year for virologists. The first giant virus was discovered in this year, which shook the virology scene, revising what was thought to be an established understanding of this elusive group and expanding the virus world from...
Mars Could Still Be Volcanically Active, Planetary Scientists Say
Volcanic activity on Mars peaked during the Noachian and Hesperian periods, between 3 and 4 billion years ago, with smaller eruptions in isolated locations continuing perhaps as recently as 3 million years ago. But, until now, there was no evidence for more geologically recent explosive volcanism on the planet. A team of planetary researchers from [...]
VLT Observes Huge Cloud of Ionized Hydrogen
Astronomers using ESO’s Very Large Telescope have taken a picture of DG121, a HII region located in the constellation of Puppis. HII regions, a type of emission nebulae, are created when young, massive stars ionize nearby clouds of interstellar gas with high-energy ultraviolet (UV) radiation. These objects are composed primarily of hydrogen, hence the name [...]
Hubble Gazes At Abell 3827, A Cluster Full of Cosmic Clues
This detailed image features Abell 3827, a galaxy cluster that offers a wealth of exciting possibilities for study....
How Planets Form Controls Elements Essential For Life
The prospects for life on a given planet depend not only on where it forms but also how, according to Rice University scientists....
First Discovery Of Methanol In A Warm Planet-forming Disk
An international team of researchers led by Alice Booth (Leiden University, the Netherlands) have discovered methanol in the warm part of a planet-forming disk....
