𧡠On 14 July 2025, the LIGO-Virgo-KAGRA (LVK) collaboration announced to have detected GW231123, a gravitational wave signal generated by the merger of the two most massive black holes ever observed. With masses of approximately 100 and β¦
𧡠In case you missed it, hereβs the #JWST wide-field view of the huge galaxy cluster MACS-J0417.5-1154, known for its stunning gravitational lensing effects and its wild ongoing merger dance. π π§ͺ βοΈ β‘οΈ webbtelescope.org/contents/new...β¦
𧡠The Cosmic Microwave Background (CMB) is like a snapshot of the newborn universe, taken 380,000 years after the Big Bang. It is a key piece of evidence for the standard cosmological model (ΞCDM), but a new study suggests that part of tβ¦
The Hubble image shows UGC 12591, a rare isolated S0/Sa galaxy β a giant hybrid between a lenticular and an early-type spiral. β‘οΈ apod.nasa.gov/apod/ap17030... Image by ESA/Hubble & NASA π π§ͺ #science #extragalactic #cosmology 1/6
First example of dark matter structure from Euclid! Scientists have put together pieces of evidence collected by Euclid, the #DarkUniverse detective π΅οΈ, to reveal the dark matter structure in the galaxy cluster Abell 2390 π www.euclid-ecβ¦
𧡠Using JWST/NIRSpec PRISM spectroscopy, an international research team has recently made an extraordinary discovery: the earliest CONFIRMED black hole, located at the heart of the CAPERS-LRD-z9 galaxy, 13.3 billion ly away. UT press relβ¦
For those who may have missed it when it first came out. This stunning infrared image from #JWST, released 11 July 2022, shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. It's the Webbβs First Deep Field... β‘οΈ weβ¦
An exciting astronomy milestone was hit last night, as DESI completed its original 5-year survey mapping 40 million galaxies in the night sky! DESI continues operation, now aiming for an 8-year survey and ~60 million galaxies. ππ§ͺ #cosmβ¦
𧡠In a 2024 paper, researchers led by Ralf Konietzka reported they determined that the Radcliffe Wave is indeed moving like a traveling wave. β‘οΈ cfa.harvard.edu/news/radclif... What is the Radcliffe Wave? It is a colossal, wave-shaped β¦
𧡠Ever wonder what the baby universe looked likeβjust 800 million years after the Big Bang? JWST has given us an amazing glimpse via a galaxy called Virgil, hidden in the iconic Hubble eXtreme Deep Field. β‘οΈ news.arizona.edu/news/monsteβ¦
𧡠Here comes a jaw-dropping discovery: the most distant confirmed protocluster ever seen with X-rays! π βοΈ Using #JWST & #Chandra together, astronomers spotted JADES-ID1βa massive structure in the making thatβs forcing us to rethink howβ¦
𧡠A research team discovered a 160,000-light-year-long bridge of neutral hydrogen gas (HI) connecting two dwarf galaxies, NGC 4532 and DDO 137. This thanks to the WALLABY project, which utilizes the ASKAP telescope in Australia. β‘οΈ theβ¦
