Carl Sagan once said that the Earth is just “dust hanging in the sun.” He will probably be excited to learn that during the new moon, the Earth is a speck of dust hanging in the moon’s tail. The moon, which has no atmosphere to protect it, is constantly under attack. When meteorites bombard its volcanic surface, sodium atoms fly …

Credit: CC0 Public Domain More Antarctic melting water is emerging than was previously known, modifying the climate, preventing the formation of sea ice and increasing marine productivity, according to a new study from the University of East Anglia (UEA). For the first time, researchers were able to obtain observations of molten water at full-depth glaciers in winter using instruments attached …

The algae forest, which only eight years ago formed a roof of leafy oceans off the coast of Northern California, is almost extinct, and scientists studying algae and the species that depend on it are worried about its inability to bounce. A new study by UC Santa Cruz found that the Sonoma and Mendocino algae forests have shrunk by an …

The STAR detector at the Brookhaven National Laboratory of the US Department of Energy Credit: Brookhaven National Laboratory Physicists studying gold ion collisions at the Relativistic Heavy Ion Collider (RHIC), a user facility at the US Department of Energy’s Nuclear Physics Research Service at the DOE National Laboratory in Brookhaven, embark on a journey through the nuclear phase of nuclear …

Scientists have begun casting one of the largest telescope mirrors ever made on Earth for Chile’s giant Magellan telescope. Why it matters: The huge telescope is designed to one day peek into the atmosphere of potentially habitable planets around distant stars, learn more about early galaxies, and explore other objects of interest. What is happening: The mirror is made in …

Scientists have long suspected that space conditions could create storm-like conditions over Earth, but now they have evidence of what researchers call a plasma space hurricane. The authors of a new report published this week in Nature Communications they say they have the first sightings of a swirling plasma mass over the North Pole resembling a hurricane. Using satellite imagery …

Perseverance has left its first traces on Mars. NASA / JPL-CalTech NASA Mars 2020 Persistence is on a roll, for the first time ever. In its first preliminary steps on the red planet, the truck-sized robot rolled forward from its landing site 13 feet (4 meters), then rotated 150 degrees to the left, supported 8 feet (2.5 meters) and took …

It’s Arctic night in the Arctic and temperatures need to drop. But the opposite is happening. Meanwhile, sea ice in the Arctic is at a record low. From the Washington Post: “Despite the onset of #PolarNight, temperatures near #NorthPole are rising. Emergency at the moment in the #Arctic, with / record low #sea,” added Daniel Swain, an air conditioner in …

The permanent rover can travel 200 meters a day, but scientists must conduct tests and safety checks before they dare. NASA’s Mars rover Perseverance embarked on its first short voyage to the surface of the red planet, two weeks after the perfect touch of a robot lab image on the floor of a huge crater, mission managers said on Friday. …
