Halo 18 is an example of a galaxy that had a head-on collision (see the panel at z=1.2) and had a disc flip (you can see this by comparing the disc orientation at z=1.4 and z=0). This image and Image ...

In the mudstones of St Bathans, Central Otago, scientists have uncovered a fossil goose that adds a surprising twist to the evolutionary story of New Zealand’s birds. The deposits, dating to the early ...

Scientists have successfully measured the magnetic field of the Lighthouse pulsar’s nebula using NASA’s IXPE. Their measurements confirm the theory that high-energy particles escape along the galaxy’s ...

Artificial sweeteners have long been marketed as harmless substitutes for sugar, but new evidence suggests they may not be as physiologically neutral as once believed. A sweeping review and ...

Forests are commonly thought of as arenas dominated by height, where the biggest trees hoard sunlight, hoping to turn their smaller neighbors into shadows. So violent is the competition in these early ...

Exoplanet WD 1856 b, shown in this artist’s concept, is a gas giant that orbits its star at a distance 50 times closer than Earth orbits the Sun. Observations by NASA’s James Webb Space Telescope ...

The ocean floor is constantly growing, forged by magmas and stretched by tectonic forces at mid-ocean ridges (MORs). Yet despite their importance, these submarine boundaries remain among the hardest ...

With the increased energy output, we would all wonder how long Earth can remain habitable now that the Sun is slowly getting more energetic. In the new study, conducted by using three-dimensional ...
