The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question...
Each of the two newly-discovered protoclusters, MAGAZ3NE J095924+022537 and MAGAZ3NE J100028+023349 (MAGAZ3NE J0959 and MAGAZ3NE J1000 for short), hosts...
The James Webb Space Telescope, an international partnership between NASA, ESA and the Canadian Space Agency (CSA), launched at 7:20 a.m. EST (13:20 CET)...
Fluorine is one of the most interesting elements for nuclear and stellar astrophysics. Fluorine abundance was first measured for stars other than the Sun...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected water and carbon monoxide molecules in a larger member of SPT-S...
The newly-discovered protocluster, named PHz G237.01+42.50 (G237 for short), contains over 60 members, including blue star-forming galaxies and active...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered two heavily dust-obscured star-forming galaxies — REBELS-12-2...
Massive galaxies in the early Universe should have contained large amounts of cold molecular gas, the fuel required to make stars. But new observations...
By combining gravitational lensing with the capabilities of NASA’s Chandra X-ray Observatory, astronomers have detected two X-ray-emitting objects —...
A team of astronomers from the United Kingdom and the United States has examined six of the most distant galaxies currently known and found that the distance...
Astrophysical observations show that supermassive black holes exist when the Universe is just 800 million years old after the Big Bang (just 6% of its...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a galactic-scale supermassive black hole-driven wind in HSC J124353.93+010038.5...
The star-forming disk galaxy with a two-armed spiral morphology, named BRI 1335-0417, existed when the Universe was just 1.4 billion years old.
ALMA detected...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) exoplanet-hunting mission have detected the rising and decaying optical afterglow...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a rotating dwarf galaxy 1/100th the size of the Milky Way in...
The two newly-discovered pairs of quasars, J0749+2255 and J0841+4825, existed 10 billion years ago and resided in the cores of merging galaxies, according...
The source of the 160,000-light-year-long jet of particles is PSO J352.4034-15.3373 (PJ352-15 for short), a rapidly growing supermassive black hole, or...
Astronomers using several ground-based telescopes have spotted the most distant cosmic jet discovered so far. Its source is PSO J172.3556+18.7734, a radio-loud...
Recent measurements of the expansion rate of the Universe have plunged the standard model of cosmology, the ΛCDM model, into a crisis. In a new paper...
ALESS 073.1, a star-forming galaxy located 12.5 billion light-years away, has all of the features expected of a much more mature galaxy and has led astronomers...
