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 ...

This image of interstellar comet 3I/ATLAS was taken on 18 January 2026 with the FORS2 instrument on ESO’s Very Large Telescope (VLT). It is a stack of several images spanning 14 minutes. As the comet ...

The discovery also sheds light on why some people are disturbed by low-frequency noise while others barely notice it. If the ...

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 ...

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 ...

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 ...

When we think of liquids, we tend to envision water flowing through a pipe or honey running off a spoon. But viscosity, the resistance of a fluid to flow, varies widely: from almost frictionless air ...

When we watch a drama unfold on screen, we instinctively begin to sketch a mental map of the characters: who is allied, who is opposed, and where the tensions lie. But how does the brain organize this ...

The Soviet PFM-1, also known as the butterfly mine for its winged shape, was designed with chilling precision. Dropped from aircraft, it flutters to the ground like a maple seed, small enough to evade ...

This digitally colorized scanning electron microscopic (SEM) depicts a number of clusters of aerobic, Gram-negative, non-motile, Acinetobacter baumannii bacteria, under a relatively low magnification ...

Artist's conception of the view from the surface of the habitable-zone super-Earth exoplanet GJ 3378b. The planet has a minimum mass just over twice that of Earth and orbits its star at a distance ...
