Astronomers are filling in the details of an intriguing planetary system around a nearby red dwarf star. L 98-59 has a likely lava-volcano world, ocean world, sub-Earth, and now a super-Earth in its (potential) habitable zone.

1/ ☄️ Comet C/2024 G3 (ATLAS) is gracing our skies, and we’d like to share some amazing images from ESO's Paranal Observatory in Chile!
This stunning shot by our friend Yuri Beletsky, with the comet next to an Auxiliary Telescope, is today's Astronomy Picture of the Day. Congrats, Yuri! 🔭 🧪

#PlanetaryParade excitement is fantastic! #DoLookUp But I'm baffled by the media saying 25th Jan is a "once in a lifetime event" 🔭🧪
The awesome foursome Mars, Jupiter, Venus & Saturn have been on display for weeks + Neptune & Uranus if you have a telescope. We won't see Mercury until late Feb🤔
