Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results show that this radiation dampens the wounded galaxy's ability to form new ...
The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS ...
Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could ...
A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for interpreting gravitational wave data from current and ...

The Ultraviolet Spectrograph (UVS) aboard NASA's Europa Clipper spacecraft has successfully completed its initial commissioning following the October 14, 2024, launch. Scheduled to arrive in the ...

Using new observations with the ALMA telescope array in Chile, researchers have compiled the most precise map of three regions in the Milky Way's Central Molecular Zone to date, providing ...

Researchers have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud, are moving in opposing directions along two distinct axes. They found that stars closer ...

By analyzing how far material ejected from an impact crater flies, scientists can locate buried glaciers and other interesting subsurface ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend months or ...

Astronomers have developed a groundbreaking computer simulation to explore, in unprecedented detail, magnetism and turbulence in the interstellar medium (ISM) -- the vast ocean of gas and charged ...

The universe is decaying much faster than thought. This is shown by calculations of scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 10^78 years ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational ...

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared ...

A research team used the German environmental satellite EnMAP (Environmental Mapping and Analysis Program) to simultaneously detect the two key air pollutants carbon dioxide (CO2) and nitrogen ...

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A ...

A long period of drought in North America has been recognized by scientists for decades. A new study links the severe climate to a change in Earth's ...

Magnetar flares, colossal cosmic explosions, may be directly responsible for the creation and distribution of heavy elements across the universe, suggests a new ...

Astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA's NICER (Neutron star Interior Composition Explorer) and other ...

In the quest toward finding the correct theory of quantum gravity, physicists have been testing the holographic principle which, they say, is a key property of any valid theory of quantum ...

Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements have revealed that beta decay of the silver-110 isomer has a strong potential ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved ...

In 1959, physicists James Terrell and Roger Penrose (Nobel laureate in 2020) independently concluded that fast-moving objects should appear rotated. However, this effect has never been demonstrated. ...

Space junk and meteoroids are falling to Earth every year, posing a growing risk as they re-enter the atmosphere at high speeds. Researchers are using infrasound sensors to track these objects, ...

The European Space Agency's Gaia mission has spotted an unusual family of stars all strangely eager to leave home -- a family we couldn't have discovered without the star-surveying ...
