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.
Professor...
Astronomers using the MeerKAT Pulsar Timing Array, an international experiment that uses the MeerKAT Radio Telescope in South Africa, have uncovered further...
It’s 7 billion years ago, and the Universe’s heyday of star formation is beginning to slow. What might our Milky Way Galaxy have looked like at that...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies...
The two galaxy clusters, known collectivity as MACS J0018.5+1626, each contain thousands of galaxies and are located billions of light-years away from...
New calculations reveal that pairs of supermassive black holes can merge into a larger black hole because of previously overlooked behavior of dark matter...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a new infrared image of a pair of interacting galaxies known as Arp 142.
This...
Astronomers using the Gemini North telescope at the International Gemini Observatory have imaged NGC 4449, a prime example of starburst activity caused...
Astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging...
This discovery was made possible by ESA’s Gaia spacecraft, which is mapping more than a billion stars throughout the Milky Way Galaxy and beyond, tracking...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found evidence for an ongoing merger of two galaxies and their central black holes —...
Using the NASA/ESA Hubble Space Telescope, astronomers have observed seven interacting galaxy systems that have long, tadpole-like tidal tails of gas,...
