An article published in "The Astrophysical Journal Letters" reports a model that traces the evolution of protoplanetary disks through five stages. A team of researchers from the ODISEA (Ophiuchus DIsc Survey Employing ALMA) project developed this model using both simulations and observations of protoplanetary disks within the Ophiuchus molecular cloud obtained using the ALMA radio telescope.

M1: The Incredible Expanding Crab

M1, the Crab #Nebula, is a supernova remnant 6,500 light-years away in Taurus. Witnessed in 1054, it spans 10 light-years and expands at 1,500 km/s. #Hubble (2005) and #Webb (2023) images show its growth.

"Globe Safety" by XKCD comic (Fediverse mirrors @xkcd @xkcdbot ) - 4 inches = 10cm. If every desktop globe was still the mass of the Earth squashed down to that size, we'd have a lot of places dangerously close to collapse into black holes. All of them. Also, your desk cannot hold a mass equivalent to the Earth. https://xkcd.com/3086/ #astronomy #physics #space

This is Messier 82 -- a starburst galaxy located in the #constellation #UrsaMajor

We talked about this very starburst galaxy in our #astronomy episode on the Ursa Major constellation here: https://starrytimepodcast.podbean.com/e/ursa-major-cosmic-background/

We also explored the #lore and #mythology of the two Ursa constellations here: https://starrytimepodcast.podbean.com/e/ursae-myths-and-retconstellations/

Looking around for what I can take images of that is not blocked by houses around me, from 3:30 to 4:30 am, and that I have not imaged before. Other than named stars, I have run out for now. Decided to do a new image of #galaxy #NGC6946. Maybe need to allow some weeks to pass before I head out again. #unistellar #odysseypro #space #astronomy #amateur

We've been researching how effective learning happens for decades. Yet most meeting & classroom practice is astrology, rather than astronomy.

This very large sunspot region, AR4079, just released 23 flares in a 24-hour period. None were powerful enough to create a serious geomagnetic storm, but it might not be done.
