Surface-bound gels may have provided the structure and chemistry necessary for life to take root on Earth. These findings could also have implications in the search for life beyond Earth.

A report published by the CDC reaffirms the effectiveness of COVID vaccines at preventing severe disease in children

Observations from the James Webb Space Telescope suggest the planet might have a nitrogen-and-methane atmosphere — but more data are needed to rule out a bare rock scenario.

The Leibniz Institute for Astrophysics Potsdam (AIP) is forming a new research group that will focus solely on the Large and Small Magellanic Clouds. The pair of irregular dwarf galaxies are satellites of the Milky Way, and are natural, nearby laboratories for studying how galaxies form and evolve. The research group will make heavy use of the spectroscopic 4MOST survey from the VISTA telescope.

Webb’s image of the enormous stellar jet in Sh2-284 provides evidence that protostellar jets scale with the mass of their parent stars—the more massive the stellar engine driving the plasma, the larger the resulting jet.

It’s one of the better annual meteor showers, and 2025 is shaping up to give sky watchers a chance to see it at its best. If skies are clear this weekend, be sure to be vigilant for the Geminid meteors.
