These mean looking sunspots are the cause of the strongest geomagnetic storm (G5 - Severe) in 20 years!
They are really huge, spanning about 16 Earth diameters. Auroras are happening now and probably will continue over the weekend.

How far did astronomers travel world-wide for conferences in 2019 in total? More than 300 times to the Moon & back! Or, to put it in astronomical units: more than 1.5 AU, so to the Sun and halfway back!

Wooooaaahhhh!
The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.
To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯
Look at ALL those galaxies, all in that tiny white box.

[updated]Dodgy image with white boxes is my own.

Our galaxy seems to be full of "rogue" planets wandering alone between the stars.
A new observation from NASA's TESS space telescope hints that these dark worlds might hugely outnumber the normal (?) planets, like Earth, that bask in the warmth and light of a sun.

We recently released version 2.1 of the #ChandraXRay Source Catalog!
In short, everything we observed that was released publicly prior to the end of 2021 has been reduced, processed, and made available for easy consumption. With over 400,000 individual sources and covering 730 square degrees, the CSC opens the X-ray sky to all astronomers -- even if you've never looked at an X-ray photon before.

The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
Several stars show deep transits consistent with discs of roughly 1 Solar radius seen at moderate inclinations, likely surrounding planets on eccentric orbits.arXiv.org
Heads Up!
Extremely Rare #citizenScience opportunity for #astronomy #astrophysics #astrodon #universeodon enthusiasts!
This year, there will be a nova, before or by September, as bright as the North Star.
After peak brightness it will remain bright enough, for several days, to observe with binoculars.
You can help research scientists with observational details.
