This floating ring is the size of a galaxy.

Jupiter with the Great Red Spot

Both Moon and Sun create beautiful

Similar in size to large, bright spiral galaxies in our neighborhood,

Its popular nickname is the Spaghetti Nebula.

How complex is Jupiter?

Like I said at the beginning, I’m not really keen on the idea of the mathematical universe. My own personal biggest objection stems from the whole point of occam’s razor: make things as simple as possible.

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence yet that a supermassive black hole can dramatically reshape its host galaxy far beyond its core.

The oceans' check engine light is on and is starting to flash violently. For the eighth year in a row, the world’s oceans absorbed a record-breaking amount of heat in 2025. That means more powerful storms for us, and changing ocean chemistry that could spell the end for some living things.

Supernovae play a crucial role in the formation and evolution of new stars. But where they occur is nearly as important as when. A new study looks at where supernovae will occur in the Andromeda Galaxy, which will help astronomers understand the role of supernovae in more detail.

Before the Romans captured Pompeii, the famous town was run by the Samnite people – and a dip in their public baths might have been an unpleasant experience

Gas and dust flowing from stars can, under the right conditions, clash with a star's surroundings and create a shock wave. Now, astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have imaged a beautiful shock wave around a dead star—a discovery that has left them puzzled. According to all known mechanisms, the small, dead star RXJ0528+2838 should not have such a structure around it. This discovery, as enigmatic as it's stunning, challenges our understanding of how dead stars interact with their surroundings.

Combining two kinds of quantum computing devices could be just the trick for taking better images of faint, faraway exoplanets

A distant black hole shredded a companion star that got too close. The star was torn to pieces and the explosion was an extremely powerful event, more energetic than a supernova. At its peak, the energy released was 400 billion times brighter than the Sun.

For centuries, the principle of symmetry has guided physicists towards more fundamental truths, but now a slew of shocking findings suggest a far stranger idea from quantum theory could be a deeper driving force

Sexual behaviour among same-sex pairs is common in apes and monkeys, and a wide-ranging analysis suggests it does boost survival
