Most exoplanets orbiting close to their stars don’t have atmospheres. But Gliese 486b – orbiting a red dwarf star only 24 light-years away – does. It’s close enough to see well. Astronomers will be watching it! Source: https://earthsky.org/space/gliese-486b-hot-super-earth-with-atmosphere…

A submersible soft robot survived the pressure in the Mariana Trench
The pressure in the world’s deepest ocean abyss can crush even the strongest enclosures, so researchers are taking another tack – using a silicon robot with wings like a manta ray Source: https://www.newscientist.com/article/2269914-a-submersible-soft-robot-survived-the-pressure-in-the-mariana-trench/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Asteroid dust in Chicxulub crater seals deal on dino extinction
Scientists examined rock cores taken from the Chicxulub crater in Mexico, site of the asteroid impact that triggered dinosaur extinction, and found iridium, a telltale sign of asteroids. Source: https://earthsky.org/earth/asteroid-dust-iridium-chicxulub-crater-dinosaur-extinction…
Gulf Stream at its weakest in over 1,000 years
A new study suggests that the Gulf Stream – an Atlantic Ocean current that plays a large role in shaping Earth’s weather patterns – is weaker now than at any point in the last 1,000 years. Source: https://earthsky.org/earth/gulf-stream-atlantic-weakest-in-over-1000-years…
Rocket Lab Reveals Plans For Reusable Rocket With 8 Ton Payload
Rocket Lab has unveiled plans for a larger rocket that can carry bigger payloads than its current reusable trooper, the Electron. It’s called the Neutron and will be capable of carrying 8 metric tons to low-Earth orbit compared to the Electron’s 660 lbs capacity. Engadget reports: The Neutron will also have a fully reusable first stage that can land on an…
