@science.socialSh2-308, the Dolphin Nebula, is a 60 light-year wide bubble blown by a massive Wolf-Rayet star 5,000 light-years away. Its blue glow marks ionized oxygen reacting to intense radiation from a star nearing its end. #Astronomy #Astrophysics #NASA #StellarEvolution

@alstirlinguk.bsky.socialFantastic evening @jodrellbank.bsky.social for a special Lovell Lecture with panel Professor Simon Garrington, David Williams-Baldwin and Phoebe Ryder. Great to see the #LovellTelescope up close again for the first time in many years. #E-Merlin #jodrellbank #Astrophysics
@claudiac.bsky.socialEver wonder about how the universe was built? The amazing and easily understood Katie Mack has a gift for us!

@thestochasticparrot.com324 real exoplanet systems beat random chance for evenly-spaced orbits: +0.065 R², CI excludes zero. The Solar System's own spacing hits the 96th percentile of its null. Not the 1766 Titius-Bode formula — a real regularity underneath it. #Astrophysics #Exoplanets #News #Journalism #Media
@science.socialThe Virgo Cluster is the heart of our local supercluster, home to 1,300+ galaxies 50M light-years away. Studying this massive structure helps astronomers map dark matter and the large-scale architecture of our universe. #space #astronomy #astrophysics
@uapdrop.bsky.socialRadio waves from exoplanet Beta Pictoris b reveal a planetary magnetic field and could refine the search for habitable worlds—likely natural auroral signals, not an alien message. #Exoplanets #HabitableWorlds #Astrophysics
@sharkbaitinspace.bsky.social💫 The universe is expanding. That we knew. But in 1998, astronomers discovered something even stranger: it's accelerating.
We understand about 5% of what the universe is made of.
That's not alarming. That's an extraordinary invitation.

@sophiejaggers.bsky.socialScientists can use Th-Ar calibration or an iodine cell to measure stellar radial velocity very precisely.
But what other reference sources can be used? And are there any "empty" wavelength regions where no suitable calibration lines can be applied?

@science.socialLocated in Cygnus, supernova remnant W63 is a massive debris shell from a stellar explosion 15,000 years ago. Spanning 150 light-years, it reveals how massive stars enrich our galaxy. #Astronomy #Supernova #Cygnus #Astrophysics #SpaceScience #space
@science.social38 Hours with the M81 Group
This 38-hour integration reveals the gravitational dance between M81 and M82, 12M light-years away. The deep exposure also highlights the faint Integrated Flux Nebula dust within our own galaxy.
@science.socialMoons at Twilight: This celestial alignment captures the waning crescent Moon alongside Saturn’s rings. These conjunctions illustrate orbital mechanics and the vast distances in our solar neighborhood. Blue hour offers perfect contrast for observation. #space #astronomy #astrophysics
