A 🧵
For centuries, Betelgeuse, the iconic red supergiant in Orion, has fascinated astronomers with its changing brightness.
Why does its light vary over a ~6-year cycle?
Thanks to the Gemini North telescope, we now have an answer: Betelgeuse has a companion star!

🆕For the first time, astronomers using our Cheops mission have caught a planet triggering flares of radiation from the star it orbits 🪐💥
These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year.

🪐 Planet self-roast!
Two NEW papers on HIP 67522, a young star with two close-in giants and clear signs of magnetic star–planet interaction. The inner planet triggers flares on its host star, exposing itself to a 6 times higher flaring rate than without interaction. #astronomy #exoplanets

Very small flares on a very small star with a bag full of very small planets. Detecting atmospheres on these terrestrial companions keeps challenging astronomers. Great work by Julien de Wit et al.! #trappist-1 #habitability #exoplanets #hubble

Stellar flares may hamper search for life in promising star system
Astronomers have been trying to detect atmospheres on planets orbiting TRAPPIST-1, but bursts of radiation from the star make this challenging
