Just beautiful on #astroph today:
"Magnetized Accretion onto and Feedback from Supermassive Black Holes in Elliptical Galaxies" by Guo et al. https://arxiv.org/pdf/2405.11711
A nomenclature of 'Blue Moon' almost never means a Moon of a blue color but with the summer nights, a literally blue appearing Moon, or Moon in the daytime is a fun one to spot. The northern hemisphere was showing off a bit before sunset, and with the May 23 full Moon so close I couldn't resist a few pictures. Happy lunar viewing! #astronomy#Astrodon#moonlight#lunar#bluesky#bluemoon
Dust, ionized oxygen, sulfur and hydrogen, stars in the making, bok globules, protoplanetary disks, Herbig-Haro objects, immense light-year distances… Ladies and gentlemen: yes the Pillars of Creation @ M 16 taken with an 8 cm aperture refractor.
Another telescope controversy is brewing, this time on #Maui
The U.S. Air Force wants to build seven more telescopes on the summit of #Haleakala to help better track the growing number of objects whizzing about in #space.
But the proposal, unveiled in public meetings on Maui for the first time last week, ran into a buzz saw of resistance similar to the ongoing opposition to the planned Thirty Meter Telescope on #Maunakea.
This image shows Gum 46, also cataloged as RCW 71, an impressive gas cloud located at a distance of about 5,500 light years from Earth and located in the direction of the Crux Constellation, revealing details thanks to the skill of astronomers Mark Hanson and Alexandr Zaytsev. At the heart of Gum 46 is a young, hot, blue star called HD311999, both the star and..... #astronomy#space#astrophysics#astrophotography

Messier 33, presented here in an excellent image by astronomer Alson Wong, is popularly known as the Triangle Galaxy. Its name is not only due to the fact that it is located in the direction of the Triangulum Constellation, but it is also the third largest galaxy in the Local Group, along with the largest, the Andromeda Galaxy Messier 31 and our Milky Way, with the..... #astronomy#space#astrophysics#astrophotography
Another “victim” of my sorting & clearing ahead of our move: five copies of my 1988 University of Edinburgh PhD thesis headed for recycling 😬✌️
But don’t panic: these are all water-damaged & I still have eight clean copies of the one hundred originally printed for me during my first postdoc at NASA Goddard 🚀🛰️
The rest were circulated to colleagues back in the early days of infrared arrays in astronomy 🔭
With global interest in the #aurora last week, don't forget that, for those in the high to mid-latitudes of the northern hemisphere, this week marks the typical start of the #noctilucent clouds season.
You'll need to stay up late. Due to night-long twilight, NLC are visible from around 23:30UT to 03UT. The early morning period is the most likely to yield displays.
For the first week or two, displays may be unimpressive. But they will soon grow into midsummer.
"'It’s difficult to say exactly how many asteroids will be lost… but preliminary results suggest that for every five near-Earth asteroids we discover, we lose one solely due to constellation interference. That’s if no mitigation measures are taken.'"
The Sun emitted a strong solar flare, which peaked at 6:54 am UT on May 10, 2024. The Solar Dynamics Observatory, which observes the Sun constantly, captured an image of this event, as seen in the bright flash towards the center of the image. Solar flares are powerful explosions of energy that can affect radio communications, electrical power grids, navigation signals and..... #astronomy#space#astrophysics#astrophotography
1112 authors for a space mission 🛰️ reference paper seems ... adequate 🤷🏽😯😁
We, the @ec_euclid will publish five main reference papers aimed at the astronomy community about the #ESAEuclid mission, the #Euclid instruments, both cosmology and other astronomy science possibilities, as well as the cosmological simulations used to test all procedures.
Available coming Tuesday, 23 May, 12:00 CEST (and on arXiv a few hours later). Stay tuned!
Coordination of 100 to 1000 co-authors is actually quite a logistical feat. For this the @ec_euclid has a dedicated membership and author database, to keep contact info and affiliations up to date, and to manage the author lists of already more than 100 publications.
The upcoming release this week has still required a lot of work behind the scenes.
