New images from the Atacama Cosmology Telescope (ACT) reveal the Universe when it was about 380,000 years old.
An image of the CMB radiation from the Atacama...
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
The newly-discovered radio jet spans an astonishing 215,000 light-years, and is associated with J1601+3102, an extremely radio-loud quasar that existed...
Dark energy — an unknown energy source that is causing our Universe’s expansion to accelerate – doesn’t actually exist, according to new research.
This...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
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...
