Fast radio burst confirmed to originate from neutron star
Fast radio bursts (FRBs) are notoriously difficult to study. They are flashes of radio light that can outshine a galaxy but often last for only a fraction of a second. For years, all we could do was observe them by random ...

Astronomers map globular clusters in the NGC 5018 galaxy group
Using the VLT Survey Telescope (VST), astronomers from Italy and Germany have observed a group of galaxies designated NGC 5018. Results of the observational campaign, published Dec. 23 on the pre-print server arXiv, yield ...
A treasure trove of unseen stars beyond the 'Dragon Arc'
Looking halfway across the observable universe and expecting to see individual stars is considered a non-starter in astronomy, a bit like raising a pair of binoculars at the moon in hopes of making out individual grains of ...

Carbon in our bodies likely left galaxy and came back on cosmic 'conveyer belt'
Life on Earth could not exist without carbon. But carbon itself could not exist without stars. Nearly all elements except hydrogen and helium—including carbon, oxygen and iron—only exist because they were forged in stellar ...

Scientists detect mysterious suppression in cosmic structure growth
A new study in published in Physical Review Letters analyzes the most complete set of galaxy clustering data to test the ΛCDM model, revealing discrepancies in the formation of cosmic structures in the universe, hinting ...
Two luminous flares detected from a nearby tidal disruption event
A group of astronomers from numerous institutions have investigated a recently discovered nearby tidal disruption event known as ASASSN-22ci. They detected two luminous flares from this event. The finding was reported in ...
Unusual binary system hosts a massive fast-spinning white dwarf
In a recent study, an Italian astronomer has investigated the nature of a binary system known as HD 49798/RX J0648.0–4418. Results of the new research, published Dec. 24 on the preprint server arXiv, yield important insights ...
Dark energy camera captures the glittering galaxies of the Antlia Cluster
NSF NOIRLab rings in the New Year with a glittering galaxyscape captured with the Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at ...

German astronomers discover three new hydrogen-deficient pre-white dwarfs
Using the X-shooter instrument at ESO's Very Large Telescope (VLT), German astronomers have detected three new pre-white dwarfs, which turned out to be strongly hydrogen-deficient. The finding was reported in a research paper ...
New method traces molecular gas mass in distant galaxies
Prof. Zhao Yinghe from the Yunnan Observatories of the Chinese Academy of Sciences, along with collaborators, have conducted a study examining the correlation between the [C II] 158 micron emission and the CO(1-0) line. Their ...
