A head-on collision with another galaxy billions of years ago may have dramatically reoriented the Milky Way’s disk, according to new supercomputer simulations...
Using the Yebes 40-m and IRAM 30-m radio telescopes, astronomers have discovered erythrulose, a four-carbon sugar commonly found in raspberries and sunless...
Astronomers using ESO’s Very Large Telescope (VLT) have measured carbon and nitrogen isotope ratios in 3I/ATLAS, the third known interstellar visitor...
Astronomers using the NASA/ESA Hubble Space Telescope have captured this vivid image of NGC 6426, an ancient globular cluster in the Milky Way’s outer...
ESA’s Euclid space telescope mapped more than 60 million stars in the Milky Way’s central bulge, producing the largest high-resolution visible-light...
The interstellar comet 3I/ATLAS carries a chemical fingerprint unlike anything in our Solar System, and it may have formed 10 to 12 billion years ago,...
A globular cluster typically has only one ancient star population. New data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space...
New simulations suggest a violent collision 11 billion years ago reshaped our Galaxy and triggered a burst of star formation.
This image from the Gemini...
For the first time, astronomers have directly detected how turbulent clouds of ionized gas between the stars bend and blur radio signal from a distant...
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,...
Using data from ESA’s Gaia mission and the NASA Exoplanet Archive, astronomers at Cornell University have identified 45 rocky exoplanets in the empirical...
Using a vast catalog of Sun-like stars built by ESA’s Gaia mission, astronomers have found strong evidence that our home star traveled outward with thousands...
The newly-identified gas cloud, dubbed G2t, follows nearly the same orbit as two known clouds, suggesting they were all expelled by a pair of massive stars...
With the record-setting image from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have mapped the molecular heart of our Milky Way...
For decades, the motions of stars near the center of our Milky Way Galaxy have been treated as some of the clearest evidence for a supermassive black hole....
NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) space telescope has completed its first...
To determine the motion of the Solar System, Bielefeld University astrophysicist Lukas Böhme and his colleagues analyzed the distribution of radio galaxies.
An...
