New Orleans - for #AAS243 - was scientifically a blast. But the city remains amazing. So much good music (wjblues.com yoshitakaz2tsuji.bandcamp.com amongst many others) & so much good food. Stand out: the blackened redfish at Coop's Place (www.coopsplace.net) which I had a decade ago, and have been craving ever since.
Discovery of the Big Ring, an ultra-large cosmological structure, by Alexia Lopez @morninglopez and her co-authors, further challenges what we understand about the universe.
This finding was announced yesterday at the Winter Meeting of the American Astronomical Society.
At a #AAS243 press conference to hear UCLan's Alexia Lopez present on her discovery of a giant ring of galaxies 1.3 billion light-years across, to add to her prior discovery of a 'giant arc'. Nice article here: https://t.co/65CQcDRDLE
That said: I'm pretty skeptical of the claim. The fact that the two structures are at about the same distance suggests that there might be some systematic effect - I don't see any reason the Universe would have a particular epoch of massive structures. #astrodon
Today is the LAST DAY of #AAS243 in New Orleans. Have you stopped by the STScI booth to talk about Hubble, Webb, Roman, MAST and employment opportunities?
If you did stop by the booth this week, what did you learn from our experts that you want others to know?
Tonight's "JWST Town Hall" at #AAS243 gave updates about the performance of the observatory, reviewed the status of science operations, and provided a summary description of Cycle 2 approved proposals, as well as the submitted Cycle 3 proposals.
This animation portrays the creation of the cat’s tail in the southwest portion of Beta Pic’s secondary debris disk, estimated to span 10 billion miles.
#AAS243: A team of astronomers used #NASAWebb to image planetary system Beta Pictoris and found a previously unseen structure: a branch of dust extending from a disk and shaped like a cat’s tail. Surprisingly, it’s a “tail” not so old as time: https://webbtelescope.pub/3RXt9Nx
#AAS243: if you're keen to hear about our current state of prediction for interstellar objects, @Chrislintott is bringing the Gaia game at 2.30 pm tomorrow in the Solar System session! (@astrohopkins.bsky.social & I are here in NZ)
Dr. Ori Fox, deputy project scientist for STScI's Roman Space Telescope Mission Office, explains his work on studying supernova explosions at #AAS243 in New Orleans. https://www.instagram.com/p/C151erzoLiP/
#AAS243: Astronomers using Hubble have found the location of the farthest and brightest fast radio burst ever detected. It exploded within a collection of merging galaxies that existed when the universe was only 5 billion years old: https://bit.ly/3tuLnwx
See the behind-the-scenes look at the production of a scientific visualization of the Pillars of Creation. It provides a peek into the science, image processing and development of 3D models using visible and infrared data from Hubble and #NASAWebb. #AAS243 https://www.youtube.com/watch?v=Slx91ASCiXw&t=2s
#AAS243 NEWS: Astronomers using #NASAWebb have found a brown dwarf with signs of possible auroras. The brown dwarf has no host star, so the team speculates that the auroras may be powered by energetic particles from a nearby, active moon: https://webbtelescope.pub/4aKMkBF
I’ll be taking part in the Beyond Academe roundtable at #aas243 this afternoon, discussing observatory/science operations as a career path in #astronomy.
Find us on the tables left of the entrance inside the exhibit hall at 3:30–4:30 pm today!
STScI’s Dr. Elena Manjavacas will explain how the study of brown dwarfs will enlighten our understanding of giant exoplanets (planets orbiting other stars than our sun) in the era of #NASAWebb—TODAY at 8:00 p.m. ET. #AAS243 https://youtu.be/ym3PtS-qNWY
#DES#astrophysicists report results that are consistent with the now-#standardcosmologicalmodel of a #universe with an accelerated expansion. Yet, the findings are not definitive enough to rule out a possibly more complex model.
