Naast de Jezero-krater op Mars ligt waarschijnlijk een vulkaan. En Marsrover Perseverance heeft mogelijk al monsters met resten van deze vulkaan verzameld. Hiermee zouden we voor het eerst vulkanische activiteit op een andere planeet kunnen dateren. Sterrenkundigen vermoeden dat er een vulkaan ligt aan de rand van de Jezero-krater op Mars. NASA’s Marsrover Perseverance is deze krater nu aan het verkennen en verzamelt hier monsters.

Eruptions from the sun are shortening the lives of satellites in Earth orbit, particularly large constellations like SpaceX’s Starlink—which could be both beneficial and a cause for concern. The sun goes through an 11-year cycle of activity, peaking with a period known as solar maximum, which most recently occurred in late 2024.

The Athena lander photographed on its side in a lunar crater. As any space watcher knows, landing on the moon is no easy feat. Of the 58 landings attempted since 1958, only 28 have been successful. The latest attempt by Intuitive Machines of Texas might contain specific lessons for NASA’s ambitions to return humans to the moon under the Artemis program, as well as the future robotic landers that the agency has funded under its Commercial Lunar Payload Services, or CLPS, program.

We just got our first-ever images of the Sun's south pole! Taken by ESA's Solar Orbiter, they reveal several interesting features, including a "speckled" magnetic field and heated plasma rising into the atmosphere. Story by me in The New York Times https://t.co/Iie7kIIZKR
Two years ago a neutrino detector in Italy discovered a monster neutrino – 35 times more energetic than any seen before. Scientists have struggled to explain it ever since. But what if it was actually a dark matter particle? Story by me in @NewScientist https://t.co/c5khoS2Xmy
