Taken on October 18, 2026, by Hera's Asteroid Framing Camera, the image shows the binary asteroid system from about 1,280 kilometers away, while the pair was roughly 197 million kilometers from Earth. Hera is visiting the site of humanity's first successful asteroid deflection experiment. Credit: ESA

NASA’s Curiosity rover conducted its first successful wet-chemistry experiment on Mars, revealing a diverse array of ancient organic molecules in a 3.5-billion-year-old rock. Nathalie Cabrol, Director of the Carl Sagan Center for Research at the SETI Institute, examines what the results mean and why they are important (even though they are #NotAliens).

If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look.

They have identified just under 50 rocky worlds most likely to be habitable out of the more than 6,000 exoplanets discovered so far.

Their research, published in Monthly Notices of the Royal Astronomical Society, would be useful in a scenario portrayed in the newly released Hollywood blockbuster Project Hail Mary.

New Discoveries on Mars and Habitability
by Nathalie Cabrol

Two NASA rovers have strengthened the case that ancient Mars may have supported life. While not evidence of life, these discoveries show that ancient Mars had complex organic chemistry, long-lasting water systems, and mineral environments capable of preserving potential signs of life—making the search more compelling and increasingly testable.

Now, scientists have revived microscopic worms frozen in Siberian permafrost for roughly 46,000 years, revealing how life can survive extreme cold through a state of cryptobiosis.

#PPOD: A flash of lightning, and then—something else. High above a storm, a crimson figure blinks in and out of existence. If you see it, you are a lucky witness of a sprite, one of the least-understood electrical phenomena in Earth’s upper atmosphere.

Sprites occur at some 80 kilometers altitude, high above thunderstorms. They appear moments after a lightning strike – a sudden reddish flash that can take a range of shapes, often combining diffuse plumes and bright, spiny tendrils.
