The mesmerising dance of Jupiter and the Galilean moons as they orbit the Sun ☀️🪐

Moons and their orbital periods, from closest to farthest (time in Earth days):
• Io: 1.8 days
• Europa: 3.6 days
• Ganymede: 7.2 days
• Callisto: 16.7 days pic.twitter.com/sfXoocJuOL
WELCOME TO L2, JWST!!! This afternoon's final mid-course burn was successful, and JWST is now in its halo orbit at the Sun-Earth Lagrange 2 point. The formal commissioning process now begins; it will take place throughout the first orbit around L2. More: https://t.co/g1hrDUYZsb pic.twitter.com/ANibKfGxcD

For anyone who’s curious, my PhD from Cornell is in Astronomy and Space Sciences, or as my aunt calls it, ASS.

It is with sadness that I post that Arlo Landolt passed away yesterday. He patiently spent his career building the network of photometric standards that so much research over the years depended on. He was modest and personable. It was always a treat to cross paths with him. pic.twitter.com/H4J2o5ehkZ

It was believed that only giant planets could sustain a ring system until 2014, when 2 rings were found around centaur (asteroid-like object) 10199 Chariklo, orbiting the Sun b/w Saturn & Uranus. It is the 5th body in the solar system to have a confirmed ring system 💍

I've posted this spectacular image of Centaurus A before, but it's worth seeing again. It shows the lobes and jets emanating from the active galaxy’s central black hole. Optical and sub millimeter data from @ESO and x-rays from @chandraxray . pic.twitter.com/cGdYcZsJ5j

Imagine what we would have learned about the Sun over the last 15 years if #NASA_Stereo had magnetographs? Seems like global observations of ☀️ are en essential #1 for #Helio_Decadal_22. Retweet if you agree! pic.twitter.com/ZIWdqo3SXV

Spectacular eruption associated with a M5.5 flare from AR 12929 (peak at 2022-01-20 06:01 UT). The remarkable coronal wave indicates a strong shock wave driven by a CME. The GOES > 10 MeV proton flux may exceed the SWPC warning threshold (10 pfu). @Loveon999 pic.twitter.com/FF01Rc1FjS

These are the planets to scale not only in size, but also in their tilt and rotation speed. Pluto and Ceres are included whether you like them or not... pic.twitter.com/eLxseaadBE

This #invasionday I'm spending all my savings on a possum coat for my Grandma to be laid to rest in. It's about $3600. The colony has made it almost impossible for us to practice many aspects of our culture but we're expected to celebrate? We barely surviving.
