New Henrietta spectrograph to probe alien atmospheres

Finding life beyond our solar system goes beyond measuring an exoplanet's size, as rocky, Earth-sized worlds might not have the conditions for life as we know it. While exoplanets can be directly imaged by blocking their ...

A rare 'triple-double' radio galaxy discovered using MeerKAT

Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located ...

Ripples in spacetime and the universe's most controversial number

Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, and they still can't ...

The JWST finds more overmassive black holes. This time in dwarf galaxies

One of the things astronomers find when they look around at galaxies is a correlation between a galaxy's mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don't anchor their galaxies; ...

X-ray lasers enable the discovery of a critical point in water

Using X-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 °C and 1,000 atmospheres. Ordinary water at higher temperatures and ...
