And now, a word from Juno at Jupiter

Juno arrived at Jupiter in 2016. It’s in a 53-day orbit around the planet. Close sweeps past the planet are called “perijoves” (peri means “near”). Here are some spectacular images from the most recent sweep, Perijove 25, in February.

This brown dwarf might look a lot like Jupiter

The cloud bands on brown dwarf Luhman 16A were found via instruments known as polarimeters. An astronomer said they’re like “… an astronomer’s polarized sunglasses. But instead of trying to block out that glare, we’re trying to measure it.”

Betelgeuse is ‘fainting’ but (probably) not about to explode

The well-known bright star Betelgeuse – a red giant star, famous for its name and for the fact that it’ll explode someday – has become noticeably dimmer since late October. Here’s what astronomers think is happening.
