'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe
'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe The James Webb telescope peered into an ancient spot of light, and found it to be the most metal-poor galaxy in the early universe. One of the greatest achievements of the James Webb Space Telescope is how it has allowed scientists to push the boundaries of astronomy by observing galaxies that existed during the early universe, less than 1 billion years after the Big Bang. This period,...
Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart
Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart In the gravitational tug of war between the dwarf galaxy siblings, it's the Small Magellanic Cloud that's losing. The Small Magellanic Cloud seems to be coming undone at the gravitational hands of its sibling galaxy, the Large Magellanic Cloud, which has been found to be unwrapping its little brother's stars. The Small and Large Magellanic Clouds (SMC and LMC for short) are two dwarf irregular...
Astrophotographer captures breathtaking view of 548 galaxies from a balcony
Astrophotographer captures breathtaking view of 548 galaxies from a balcony Over 60 hours of light data was used to create this stunning view of the gravitationally bound "Leo Triplet" galaxies. Astrophotographer ing. Cornelis Van Zuilen has shared a staggeringly detailed image of the galaxies known as the "Leo Triplet", after spending 60 hours capturing the light of the cosmic heavyweights from his balcony in the Netherlands.
Constraining reionization morphology and source properties with 21cm galaxy cross-correlation surveys
arXiv:2601.18627v2 Announce Type: replace-cross Abstract: Cross-correlations between 21cm observations and galaxy surveys provide a powerful probe of reionization by providing robustness against foreground contamination while linking ionization morphology to galaxies. We quantified the constraining power of 21cm galaxy cross-power spectra for inferring the neutral hydrogen fraction, $x_\mathrm{HI}(z),$ and mean overdensity, $\langle 1+\delta_\mathrm{HI} \rangle(z)$, exploring dependence on...
Do galaxies have a 'kill switch' that makes them stop growing?
Do galaxies have a 'kill switch' that makes them stop growing? Above a certain threshold, galaxies stop growing , no matter how much raw material they have on hand. The question is: what flips the switch?
MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk
June 6, 2026 report MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk Tomasz Nowakowski Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational campaign, published May 27 on the pre-print server arXiv, offer new insights...
Samsung Galaxy A37 review: A solid deal even in this economy
Samsung Galaxy A37 review: A solid deal even in this economy With the price of damn near everything going up these days, finding a good deal is harder than ever, especially when you're shopping for electronics. However, after refreshing its midrange phone lineup for 2026, Samsung has a new contender for the best phone under $500 in the Galaxy A37 5G. It's not the fastest or flashiest device around, but for anyone who just wants a solid Android handset for a decent price, this is it.
Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
June 2, 2026 report Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study was posted to the preprint server arXiv on May 18.
James Webb telescope discovers 'naked' black hole that somehow formed before its own galaxy
The galaxy cluster Abell 2744, imaged here by the James Webb Space Telescope, magnifies the light of some of the most distant galaxies and black holes in the known universe. New research uncovers the secrets of one such black hole.
James Webb Space Telescope discovers a black hole that formed before its host galaxy. Scientists aren't sure how
An image from NIRCam on NASA’s James Webb Space Telescope shows Little Red Dot Abell2744-QSO1, magnified and triply imaged by galaxy cluster Abell 2744 (Pandora’s Cluster).
