VLSS J0318.9+5755, a strange, musical-note-shaped radio source hiding behind the Milky Way’s dusty disk, has turned out to be the glowing remains of...
A barred spiral galaxy called NGC 4698 has a bizarre structure in which its central stars and gas rotate perpendicular to the galaxy’s main disk, possibly...
When two black holes merge, the resulting object rings like a struck bell, radiating gravitational waves that fade in a distinctive pattern called ringdown....
A new image from the Gemini North telescope on Maunakea in Hawai’i offers the sharpest look yet at a striking pair of interacting spiral galaxies, cataloged...
Astronomers using the NASA/ESA Hubble Space Telescope have found definitive evidence that the young Milky Way swallowed a dwarf galaxy just two billion...
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...
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...
Researchers have developed a new method to identify whether black hole mergers occurred inside dense clouds of dark matter, potentially opening a fresh...
Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint...
In a paper to be published in the Planetary Science Journal, scientists from SETI Institute, Southwest Research Institute, Caltech and the Observatoire...
Astronomers discovered an enormous galaxy cluster called RM J130558.9+263048.4 on December 31, 2020; the date, combined with the bubble-like appearance...
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...
Using data from the 10-m space radio telescope RadioAstron and a network of 27 ground-based observatories, astronomers have detected an unusual ribbon-like...
Using twin detectors of NSF’s Laser Interferometer Gravitational-wave Observatory (LIGO), astrophysicists with the LIGO-Virgo-KAGRA (LVK) Collaboration...
It is commonly believed that our own Milky Way Galaxy is on a collision course with the neighboring Andromeda galaxy. As a result of their merger, predicted...
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...
Arp 105 is characterized by a tidal tail of stars and gas more than 362,000 light-years long.
The elliptical galaxy NGC 3561B (upper left) and the spiral...
Ultrahigh energy cosmic rays are the highest-energy particles in the Universe, whose energies are more than a million times what can be achieved by humans.
