Ancient starburst galaxies that formed 2-3 billion years after the Big Bang are unusually hot and contain unexpected elements, like nickel, according to...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized ultracool red dwarf, ideally suited for in-depth...
Jupiter’s icy moon Europa has an ocean beneath a crust of water ice. Solid carbon dioxide has previously been observed on the surface, but the source...
Gravitational lensing provides unique insights into astrophysics and cosmology. Using ESO’s Very Large Telescope, astronomers have discovered a new strong...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered carbon dioxide and methane in the atmosphere of the habitable zone exoplanet...
Chromium hydride is often used to probe atmospheric temperatures and classify objects called brown dwarfs into spectral types because it’s abundant only...
Active galactic nuclei are primarily powered by a supermassive black hole lying at the center of a host galaxy that is accreting matter from its vicinity....
Astronomers using the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope (VLT) have observed a large dark spot in Neptune’s...
Named the Swift Ray 1, the real-life Star Trek ‘tricorder’ is a novel point-of-care hyperspectral imaging device that allows the acquisition of medical-grade...
Astronomers using NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and other telescopes have found evidence for a massive stellar disruption (over...
Using spectropolarimetric data gathered by various telescopes around the globe, astronomers from the University of Amsterdam and elsewhere have identified...
During the first 500 million years of cosmic history, the first stars and galaxies formed, seeding the Universe with heavy elements and eventually reionizing...
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects: hydrogen burning Population III...
Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...
Using infrared spectral data from NASA’s Spitzer Space Telescope, Instituto de Astrofísica de Canarias astronomer has detected the aromatic amino acid...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
