In his new paper, Professor Jonathan Tan, an astrophysicist at the University of Virginia and the Chalmers University of Technology, proposes that Population...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have observed the Hubble Ultra Deep Field (HUDF), an area of deep space with nearly 10,000...
As part of the CRISTAL (CII Resolved ISM in STar-forming galaxies with ALMA) survey, astronomers peered back to when the Universe was only about one billion...
Present-day disk galaxies often exhibit distinct thin and thick disks. The formation mechanisms of the two disks and the timing of their onset remain open...
The first generation of stars (Population III) must have formed from the unenriched gas that permeated the infant Universe. These stars produced the first...
As part of the Chicago-Carnegie Hubble Program, astronomers using the NASA/ESA/CSA James Webb Space Telescope have performed new measurements of the Hubble...
Intense radiation from a quasar in one of these galaxies alters the gas properties in the other galaxy and dampens its ability to form new stars, according...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered an ultra-massive grand-design spiral galaxy that existed just one billion...
The Lyman-apha light from JADES-GS-z13-1 has taken nearly 13.47 billion years to reach us, as it dates back to just 330 million years after the Big Bang.
This...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected oxygen in the most distant confirmed galaxy ever found, JADES-GS-z14-0....
The Lambda-CDM (ΛCDM) model has been the foundation of modern cosmology for some time now, successfully describing large-scale structures in the Universe....
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....
