Publication alert! I am glad to inform you that our new paper on the optical, UV, and X-ray studies of the 2017–2022 eruptions of the remarkable recurrent nova M31N 2008-12a is out now in The Astrophysical Journal @AAS_Publishing . (Link in the end) 1/n
Breaking news!🎉 Today we announce the most precise measurements of our expanding Universe using the BAO signal in 6.1 Million galaxies and quasars from Year 1, tracing dark energy through cosmic time. See @BerkeleyLab PR at newscenter.lbl.gov/2024/04/04/des… 1/10 📸 Credit: @ClaireLamman

未発見の太陽系小天体を探せるWebアプリ「COIAS（@coias_t09）」。900名以上のユーザーによって、7万を超える新天体候補の捜索に成功しているとのこと（2月13日時点）🌟 astroarts.co.jp/article/hl/a/1… #星ナビ 4月号では星見まどか（@Madoka_Hoshimi）さんによる紹介記事を掲載しています！
Keep your eyes to the sky. There's a good chance that a bright new star will appear in the constellation Corona Borealis over the next six months. This is a rare event -- a recurring nova that last erupted 80 years ago. (I've simulated the view here.) blogs.nasa.gov/Watch_the_Skie…
So about a year ago, I was putting my little guy to bed in his crib and I noticed a strange detail on the solar system poster up on his wall …
Am Abend wurde ein Brocken (1 Meter groß) entdeckt, der gleich gegen 1:30 MEZ über Ostdeutschland verglühen soll. Bei der Größe ist das Objekt ungefährlich und wird nur einen schönen Meteor abgeben. #Sar2736

Confirmation from my colleague Peter Jenniskens that four Polish meteorite hunters reported to have found fragments of the asteroid #2024BX1, which burned above Germany last saturday. Initial assessments are that they are Eucrites, pieces of the large main-belt asteroid Vesta.

Prague's view of #Sar2736: a minor planet entering Earth's atmosphere on Jan 21, 2024, at 00:32 UT.
Check out the latest results of minor planet hunting on COIAS! We have published a list of 36 objects reported on COIAS and assigned with provisional codes, as well as their measurers, on the Data Analysis page. web-coias.u-aizu.ac.jp/data_analysis #COIAS
Using ESO's #VLT and NTT, among other instruments, astronomers have found direct evidence that #supernovae 💥 give rise to #BlackHoles or neutron stars — a process at which prior clues hinted, but which had never been witnessed in real time until now. 1/

#TCoronaBorealis at 3.000 light years from us might erupt again in few days. Here is marked as T in a chart of its constellation. It could become a naked eye star suddenly, so I recommend this @SkyandTelescope article to understand a #RecurrentNova system skyandtelescope.org/observing/what…
Skywatchers: A star system located 3,000 light-years away in the Northern Crown constellation may become visible to the unaided eye in the coming weeks or months! T Coronae Borealis last erupted in 1946, and astronomers are seeing signs that it might happen again any day now.
What happened: Neptune's moon Triton passed in front of a star. We observed it with the GROWTH-India Telescope. What it taught us: atmospheric pressure on the moon, details of N2 condensation, and more! Happy to be a part of this work led by @BSicardy arxiv.org/abs/2402.02476
