Old stars don’t have hot Jupiters, suggests study
Hot Jupiters may not last long near sun-like stars. Credit: NASA/JPL-Caltech As we began to discover hundreds, then thousands of exoplanets, we found that there were two types of worlds unlike anything in our solar system. The first are super-Earths. These worlds straddle the line between large rocky worlds like Earth and small gas planets…

A Bear on Mars? – NASA
NASA/JPL-Caltech/University of Arizona The Mars Reconnaissance Orbiter (MRO) captured this bit of ursine pareidolia on Dec. 12, 2022. While it resembles a bear we might see on Earth, this is actually a hill on Mars with a peculiar shape. A V-shaped collapse structure makes the nose, two craters form the eyes, and a circular fracture…

Pulsar’s Record-Breaking Gamma Rays Baffle Scientists
Using the H.E.S.S. observatory in Namibia, scientists have detected exceptionally high-energy gamma rays from the Vela pulsar, challenging established theories on pulsed gamma rays from such stars. These gamma rays, with energy levels 200 times more potent than any previous observations from the Vela pulsar, have prompted researchers to reconsider the mechanisms behind such powerful…
