Engineers test an idea for a new hovering rover      (via sciencedaily.com) 

MIT aerospace engineers are testing a concept for a hovering rover that levitates by harnessing the moon's natural charge. The design uses tiny ion beams to charge up the vehicle and the surface underneath, with little power needed. Such an ion boost could be strong enough to levitate a 2-pound vehicle on the moon and large asteroids.

Could acid-neutralizing life-forms make habitable pockets in Venus' clouds?      (via sciencedaily.com) 

A new study supports the longstanding idea that if life exists, it might make a home in Venus' clouds. The study's authors identified a chemical pathway by which life could neutralize Venus' acidic environment, creating a self-sustaining, habitable pocket in the clouds.

Sauropod dinosaurs were restricted to warmer regions of Earth      (via sciencedaily.com)     Original source 

A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.

Advanced analysis of Apollo sample illuminates Moon’s evolution      (via sciencedaily.com) 

Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information about the complex cooling and evolutionary history of the Moon. The diffusion patterns preserved in the mineral grains were consistent with a rapid cooling history of no more than 20-million-years at high temperatures. The finding challenges previous estimates of a 100-million-year cooling duration and supports initial rapid cooling of magmas within the lunar crust.

A spacecraft has 'touched' the sun for the first time      (via sciencedaily.com) 

On April 28, 2021, NASA's Parker Solar Probe reached the sun's extended solar atmosphere, known as the corona, and spent five hours there. The spacecraft is the first to enter the outer boundaries of our sun.

A young, sun-like star may hold warnings for life on Earth      (via sciencedaily.com) 

Last year, scientists looked on as a star called EK Draconis ejected a massive burst of energy and charged particles many times more powerful than anything recorded on Earth's sun. Such explosive events may have been common in the early years of our solar system, the researchers say.

ESO telescope images planet around most massive star pair to date      (via sciencedaily.com) 

The European Southern Observatory's Very Large Telescope (ESO's VLT) has captured an image of a planet orbiting b Centauri, a two-star system that can be seen with the naked eye. This is the hottest and most massive planet-hosting star system found to date, and the planet was spotted orbiting it at 100 times the distance Jupiter orbits the Sun. Some astronomers believed planets could not exist around stars this massive and this hot -- until now.

Lunar radar data uncovers new clues about moon’s ancient past      (via sciencedaily.com) 

The dusty surface of the moon -- immortalized in images of Apollo astronauts' lunar footprints -- formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient layer of this material, covered by periodic lava flows and now buried under the lunar surface, could provide new insight into the Moon's deep past, according to a team of scientists.
