Behold, directly overhead, a certain strange star was suddenly seen...
Amazed, and as if astonished and stupefied, I stood still.

The Sun's Red Dwarf Neighbors Provide Clues to Origins of Carbon and Oxygen

Universe Today - Fri, 01/23/2026 - 7:40pm

We live near a fusion reactor in space that provides all our heat and light. That reactor is also responsible for the creation of various elements heavier than hydrogen, and that's true of all stars. So, how do we know that stars are element generators?

The Many Faces of Monster Galaxies

Universe Today - Fri, 01/23/2026 - 3:38pm

The earliest galaxies in the universe earned the nickname "monster galaxies" for good reason, they formed stars at rates hundreds of times faster than the Milky Way, growing rapidly after the dawn of time. Astronomers using ALMA and the James Webb Space Telescope have now revealed that three such monsters each achieved their extraordinary growth through completely different mechanisms. By comparing where stars are forming today with where they formed in the past, researchers discovered that galaxy collisions, internal instability, and minor mergers can all trigger these growth spurts, fundamentally changing our understanding of how the universe's most massive galaxies came to be.

An Almost-Famous Galaxy Cluster Is The JWST's Picture Of The Month

Universe Today - Fri, 01/23/2026 - 3:02pm

Gravitational lensing is a powerful tool that brings impossibly distant galaxies into reach. The JWST uses galaxy clusters and their overpowering to magnify background galaxies that are otherwise beyond our observational capabilities. One cluster, named MACS J1149.5+2223, is 5 billion light-years away and holds at least 300 galaxies, probably many more. It's been chosen as the JWST's Picture Of The Month.

Sea turtles may be more resilient to global warming than we thought
