Black hole destroys star, goes after another

A massive black hole has torn apart one star and is now using that stellar wreckage to pummel another star or smaller black hole that used to be in the clear.

Large radio bubble detected in galaxy NGC 4217

An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in ...

The sun unleashes its strongest flare this cycle

Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.

Gravitational lens confirms the Hubble tension

We've known the universe is expanding for a long time. The first solid paper demonstrating cosmic expansion was published by Edwin Hubble in 1929, based on observations made by Vesto Slipher, Milton Humason, and Henrietta ...

Hubble observes a peculiar galaxy shape

This NASA/ESA Hubble Space Telescope image reveals the galaxy, NGC 4694. Most galaxies fall into one of two basic types. Spiral galaxies are young and energetic, filled with the gas needed to form new stars and sporting spiral ...

Webb telescope detects unusual gas jets from Centaur 29P

Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the sun between Jupiter and Neptune. NASA's James Webb ...
