Water is made of two hydrogen atoms and one oxygen atom, hence its H2O formula. In typical water molecules, though, those hydrogen atoms have just one...
Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have detected enormous hydrogen halos, called Lyman-alpha nebulae, around more...
New computational simulations suggest ice-giant planets like Uranus and Neptune harbor a quasi-one-dimensional superionic state of carbon hydride that...
The newly-discovered star, SDSS J0715-7334, formed in the halo of the Large Magellanic Cloud and migrated to our Milky Way Galaxy billions of years ago,...
A new close-up of the Triangulum galaxy, captured with ESO’s Very Large Telescope (VLT), traces the tangled gas and dust that shape how stars are born...
Using spectral data from the Hobby-Eberly Telescope at McDonald Observatory, astronomers have produced the most detailed 3D map yet of faint cosmic structures...
Mars almost certainly once held abundant water. Until now, observations have shown that most atmospheric water loss occurs during the Red Planet’s southern...
Astronomers using the NASA/ESA Hubble Space Telescope have confirmed the existence of starless, hydrogen-rich objects dominated by dark matter. Named Reionization-Limited...
Scientists using the Ultraviolet Spectrograph (UVS) instrument aboard NASA’s Europa Clipper spacecraft have observed 3I/ATLAS, only the third confirmed...
The newly-discovered galaxy filament spans at least 50 million light-years and resides 140 million light-years away. The galaxies are orbiting around the...
Astronomers using the NASA/ESA Hubble Space Telescope have released a beautiful new image of part of N159, a massive star-forming cloud located about 160,000...
The new ultraviolet (UV) images from the Imaging Ultraviolet Spectrograph (IUVS) camera aboard NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN)...
Astronomers using the Green Bank Telescope (GBT) have created the large-scale maps of carbon monoxide (CO)-dark molecular gas for the star-forming complex...
As part of the Widefield ASKAP L-band Legacy All-sky Survey (WALLABY), an international team of astronomers has observed the dwarf galaxy pair NGC 4532...
White dwarfs are the dense cores left behind when stars exhaust their fuel and collapse. They are Earth-sized stellar embers weighing typically half as...
The first generation of stars (Population III) must have formed from the unenriched gas that permeated the infant Universe. These stars produced the first...
The Jovian aurorae are hundreds of times brighter than those seen on Earth, says a team of astronomers by University of Leicester’s Dr. Jonathan Nichols.
These...
Long invisible to astronomers, the newly-discovered molecular cloud is one of the largest single structures in the sky and among the closest to the Sun...
A new study by University of California, San Diego computational astrophysicist Ethan Nadler shows that star formation can occur in halos down to 10 million...
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...
