The nearest single star to Earth has four small planets.

Science News reports: "This is the second study in six months to find planets around Barnard’s star."

Four Sub-Earth #Planets Orbiting Barnard's Star from MAROON-X and ESPRESSO: https://iopscience.iop.org/article/10.3847/2041-8213/adb8d5 -> Confirmed at Last - Barnard’s Star Hosts Four Tiny Planets: https://aasnova.org/2025/03/11/confirmed-at-last-barnards-star-hosts-four-tiny-planets/

Saturn’s largest moon, #Titan, is particularly captivating for scientists.

It is known to host an #atmosphere about 1.5 times denser than Earth’s and bodies of liquid on its surface.

But even such a large #moon lacks the mass to keep a tight hold on its atmosphere.

Now, new experimental research shows that the chemical compounds in Titan’s atmosphere could emerge from processes in its interior.

#Cryovolcanism replenishes its thick atmosphere.

Scientists have discovered a 3-billion-year-old beach buried on Mars

https://phys.org/news/2025-02-scientists-billion-year-beach-mars.html

Small #planets have nearly circular orbits, while giant planets have orbits about four times more elliptical.

The finding points toward two different pathways by which large and small planets form.

The #eccentricity split coincides with several other iconic features in the #exoplanet population, such as the high abundance of small planets over large planets and a tendency for giant planets to form only around #stars enriched in heavy elements.

Planets are formed from protoplanetary disks, spinning clouds of dust and gas that are the perfect ingredients for #planet formation.

A fresh look at past data reveals that #exoplanets with masses similar to #Jupiter formed much sooner than previously thought.

New results provide information about the early timing of accretion—the process of accumulating a large amount of gas and dust to make large #planets.
