Nicknamed the Firefly Sparkle, the newly-discovered galaxy existed approximately 600 million years after the Big Bang and consisted of a least 10 star...
New observations from the NASA/ESA/CSA James Webb Space Telescope confirms previous measurements by the NASA/ESA Hubble Space Telescope of distances between...
Primordial black holes have been theorized for decades and could even be ever-elusive dark matter. Still, no primordial black hole has ever been observed....
Astronomers using the Dark Energy Spectroscopic Instrument (DESI), a state-of-the-art instrument mounted on NSF’s Nicholas U. Mayall 4-m telescope at...
The standard model predicted that the NASA/ESA/CSA James Webb Space Telescope would see dim signals from small, primitive galaxies. But data are not confirming...
Named LID-568, this 7.2-million-solar-mass black hole appears to be feeding on matter at a rate 40 times its Eddington limit and is seen as it existed...
According to the prevailing inflationary universe theory, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of...
REBELS-25 existed as early as 700 million years after Big Bang, according to a paper published in the Monthly Notices of the Royal Astronomical Society.
This...
Astrononomers using the NASA/ESA/CSA James Webb Space Telescope have detected that GS-10578, a massive, quiescent galaxy at redshift of 3.064 (look-back...
It’s 7 billion years ago, and the Universe’s heyday of star formation is beginning to slow. What might our Milky Way Galaxy have looked like at that...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies...
In a paper published today in the Astronomical Journal, astronomers analyzed the evolution of massive galaxies at redshifts of 4-8 selected from the JWST...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted at least five young globular clusters within SPT 0615-JD1 (also known as the...
Astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging...
Astronomers using the NIRSpec (Near-Infrared Spectrograph) instrument onboard the NASA/ESA/CSA James Webb Space Telescope have obtained the spectrum of...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found evidence for an ongoing merger of two galaxies and their central black holes —...
Astronomers at MIT have discovered thee extremely ancient stars in the Milky Way’s halo, a cloud of stars that envelopes the entire main Galactic disk....
To study dark energy’s effects over the past 11 billion years, the Dark Energy Spectroscopic Instrument (DESI) has created the largest 3D map of our...
