Astronomers have turned the Atacama Large Millimeter/submillimeter Array (ALMA) into a time machine to peer back in cosmic time to 1 billion years after the Big Bang.

The awe-inspiring distances of the cosmos are hard to visualise, so how can we be certain we are measuring them correctly?

Deep within the Milky Way’s core, researchers have uncovered cold gas clouds racing through a superheated galactic wind.

The Atacama Large Millimeter/submillimeter Array (ALMA) has been used to discover REBELS-25, a Milky Way-like galaxy from the ...

PhoSim simulates the atmosphere, including air turbulence, as well as distortions from the shape of the telescope’s mirrors and the electrical properties of the sensors. The photons are propagated ...

A mystery interstellar object discovered last week is likely to be the oldest comet ever seen – possibly predating our solar system by more than three billion years, researchers say. The "water ...

A newly discovered comet, 3I/ATLAS, may be the most ancient visitor ever detected, potentially older than our solar system itself. Unlike previous interstellar objects, this ice-rich comet seems to ...

As 3I/ATLAS approaches the sun, astronomers expect its frozen ices to sublimate, releasing gas and forming a glowing coma and ...
