Fine definition is missing in the comet's tails at the moment. But it was passing another comet as it moved through Auriga's Kids. Can you spot the fainter comet?

phys.org/news/2023-02-e… An international team of astronomers has confirmed the existence of K2-415b, an Earth-sized exoplanet circling an M dwarf star, just 72 light years away from Earth.

This week on #SpaceToGround, learn more about the 3D bioprinting and dexterous manipulation research happening in the microgravity environment on the space station and how it can improve life on Earth and future space missions. 🧫🦾

"A New Spider Joins a Deadly Club - AAS Nova" aasnova.org/2023/02/17/a-n… Tiny but deadly, black widow pulsars are some of the cruelest astronomical objects in the galaxy: first they consume most of their companion, then they destroy the remains.

Our Fermi Gamma-ray Space Telescope is named after Enrico Fermi in recognition of his work on how cosmic phenomena accelerate charged particles, which is crucial to understanding the objects his namesake satellite studies. More about Fermi: tmblr.co/Zz_Uqj2j-ZwJ0 #FermiFriday

Nice one to everybody 😉

💫 This week's #repost goes to Mario Weigand! "The Grand Design Spiral Galaxy Messier 81 aka "Bode's Galaxy" in Ursa Major! Taken with a Planewave CDK 14" at Trevinca Skies in Spain."

New Baader O-III Super-G Filter (9nm). A. Bringmann tested the new 20nm H-alpha bandpass filter instead of a normal 100nm R filter and the new 9nm O-III Super-G filter instead of the normal 100nm G filter. The result is a "20nm H-alpha/9nm Super-G/100nm B" image.

The much-debated tip of the Red Giant Branch brightness in the Magellanic Clouds sets the scale of the Universe. Taylor presents a data-driven sample selection that addresses this debate & produces measurements consistent with independent constraints nature.com/articles/s4155…

The launch has been cancelled due to winds. The weather needs to be perfect, we're taking our time for a successful mission. More info about the next attempt will come after tomorrow’s meteorological briefing. #BRORkiruna
