#UMPlus - IC 4633

https://www.universomagico.net/2024/04/ic-4633.html

The image taken by the Hubble Space Telescope shows the spiral galaxy IC 4633. It is located in the Apus Constellation and is located at a distance of about 100 million light years from the Milky Way. IC 4633 is a galaxy rich in star formation activity, as well as hosting an active galactic nucleus at its center. From our point of view, the.....

hello there, i'm antares! i like linguistics (can speak english, russian and spanish), music (i play guitar) and fixing things (mainly finding ways to use old tech and sewing). i've never been a big poster, but spent a lot of good time lurking in and fandoms
things that i'm also into:
any pronouns are fine, but in english i prefer they/them

A colossal simulated cosmic tsunamis at the periphery at a cluster of galaxy: this giant growing pressure discontinuity surfs at the speed of about 4000 km/s and it marks the boundary between the rarefying and the collapsing Universe.

American astronomer Annie Jump Cannon died in 1941.

Cannon developed a system of stellar classification based on spectral characteristics, which became known as the Harvard Classification Scheme (she was one of the "Harvard Computers"). She classified hundreds of thousands of stars, organizing them by temperature and spectral characteristics. Her work laid the foundation for our understanding of stellar evolution and the composition of stars.

One of Cannon's most significant contributions was the creation of the Henry Draper Catalogue, which listed the spectral classifications of nearly 400,000 stars. She also developed the mnemonic device "Oh, Be A Fine Girl, Kiss Me" to help remember the spectral classes: O, B, A, F, G, K, M.

In 1925, she became the first woman to receive an honorary doctorate from Oxford University.

The Women Who Mapped the Universe and Still Couldn’t Get Any Respect

At the beginning of the 20th century, a group of women known as the Harvard Observatory computers helped revolutionize the science of astronomy.

Has anyone ever overlaid the Doom 1 episode 1 map onto actual photos of Phobos? It's so disappointingly small that I bet a lot of the UAC base would be visible.

Happy 51st B'day to Deep Space Station 43 (DSS43)! 📡

One of my fav antennas, and at 70m diameter, the largest steerable antenna in the Southern Hemisphere, located at @canberradsn

DSS43 keeps in touch with super important missions like Voyager2, only acquirable from this station!

Read the piece I wrote about CDSCC in #SpaceAustralia: https://www.spaceaustralia.com/feature/canberras-deep-space-network-ready-return-moon

- WR 8 by Martin Pugh

https://www.universomagico.net/2024/04/wr-8-por-martin-pugh.html

WR 8, seen here in an excellent image by astronomer Martin Pugh, is classified as a Wolf-Rayet type star. It is located in the direction of the southern constellation of Puppis and is located at a distance of more than 2,000 light years from the Solar System. As it has a brightness of tenth magnitude, it cannot be seen without optical aid. Wolf-Rayet stars are.....

I have a perversion to disclose here.
Please don't judge me.

I love editing stuff, both my stuff and my students and collaborators's stuff.
So at present I can edit via overleaf about 4 papers in progress by my students, 1 master thesis, 1 paper of mine under review and another in preparation.

Basically, paradise!

English astronomer Edward W. Maunder was born in 1851.

The Maunder Minimum, named after him, refers to a period of low solar activity that occurred from about 1645 to 1715. During this time, very few sunspots were observed, indicating a decrease in solar magnetic activity. His research into historical records of sunspot observations led to the recognition of this extended period of solar quiescence, which is now associated with a decrease in global temperatures on Earth.

Strange phenomenon on 17 November 1882, observed and described by Maunder in The Observatory, June 1883 (pp. 192–193) and April 1916 (pp. 213–215), which he termed an "auroral beam" and "a strange celestial visitor." Drawing by astronomer and aurora expert John Rand Capron, Guildown Observatory, Surrey, UK, who also observed it. From Philosophical Magazine, May 1883.

French astronomer Charles Messier died in 1817.

He is best known for his catalog, the Messier Catalog (contains 110 objects), which lists various astronomical objects, including nebulae, star clusters, and galaxies. Messier was primarily interested in comet hunting, and his catalog was created to help him and other astronomers differentiate between permanent celestial objects and comets, which could easily be mistaken for new discoveries.

The Orion Nebula as drawn by Messier, and which he gave the designation M 42 in his catalogue Charles Messier - Stoyan R. et al. Atlas of the Messier Objects: Highlights of the Deep Sky. — Cambridge: Cambridge Univercity Press, 2008. — P. 33.

fascinating work on the comparison of simulated structure formation between the standard Poisson equation solution of gravity vs the Mongere-Ampere model

https://arxiv.org/abs/2404.07697

by @BrunoLevy01 and colleagues.

I like the concept that the Mongere-Ampere description might be an effective emergent description of gravity in an N-body system, e.g. see the final discussion of the paper.

*** SUPERNOVA ALERT ***
🔭📸🚨

Astrophotographers/astronomers with 'scopes capable of low-res spectrography:

Turn your telescopes to NGC 3621, a field galaxy only 7 MPC away! Supernova alert issued with progenitor data available. ⭐💥

NGC 3621 (aka the Frame Galaxy or Southern Cross Galaxy) is fairly bright and if you are around the same latitude as Sydney (many southern cities) it gets very near zenith around 9 - 10pm local time, so an easy and bright target.

Hubble tracks Jupiter's stormy weather

https://esahubble.org/news/heic2404/?lang

The giant planet #Jupiter, in all its banded glory, is revisited by the #HubbleSpaceTelescope in these latest images, taken on 5–6 January 2024, that capture both sides of the planet. Hubble monitors Jupiter and the other outer Solar System planets every year under the Outer Planet Atmospheres Legacy programme (OPAL).

Webb peers into the tendrils of NGC 604

https://esawebb.org/news/weic2407/?lang

Two new images from the #JamesWebbSpaceTelescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) showcase the star-forming region NGC 604, located in the Triangulum Galaxy (M33), 2.73 million light-years away from Earth. In these images, cavernous bubbles and stretched-out filaments of gas etch a more detailed and complete tapestry of star birth than seen in the past.
