Attention Amateur Astronomers who take images of Jupiter. 🔭
Starting this Friday, four separate #JWST programmes will be exploring physical processes in Jupiter's atmosphere and ionosphere. We're asking amateur astronomers to help provide context imaging over the next few weeks to understand how the atmosphere is changing with time. #planetaryscience

Magnetars, a type of neutron star, have magnetic fields trillions of times stronger than Earth's. They can literally strip the electrons from the atoms of your body.

Susan B. Anthony was born #OTD in 1820.

Active until she died in 1906. She never got to vote in her lifetime (well, legally that is).

Every atom in your body was forged in the core of a star; we are literally made of stardust. 98% of the universe is Hydrogen and Helium. Everything else was made by stars converting these materials into other elements.

Clear, dark skies are essential; head away from city lights for the best results. If you can't find dark skies, you may be able to use a light pollution filter. Here's the one I use: https://shorturl.at/QSDhs

Did you know that Outer Space is only 62 miles away? Although there is no official solid boundary for where space begins, the Kármán line sits at 62 miles (100km) above sea-level and is conventionally used as the start of outer space in space treaties or for aerospace records keeping.
