Tonight I decided to try something new. I managed to detect Exoplanet TOI 3714b transiting its host star using my 190MN scope and 2600MM camera. Totally blown away that this is possble from my back yard here in the UK. Transit took 1H 38mins and was about 5% in depth 🤯. #Astrophotography #exoplanet

One Rubin image = up to ~10,000 alerts! 🌌🔭
From supernovae to asteroids, comets, and more, Rubin will capture the Universe in action every night. ☄️✨

NASA FINESST Astro results are out, plot with some numbers below. Congrats to the +450 who applied! I did not get it, but I know I gave my best. Simulations and cosmology were big this year, with fewer observational and stars projects.
