When it comes to the Milky Way and Andromeda galaxies, there’s a whole “will they or won’t they” thing going on. In 2012 scientists published their results of Hubble Space Telescope observations ...

Astronomers have spotted a colossal explosion coming from a pair of merging neutron stars lurking within the remnants of an ancient galaxy pileup. The unexpected "collision within a collision" could ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

For decades, scientists have suspected that a violent collision with a smaller galaxy played an important role in shaping the Milky Way as we observe it today. This suspicion was confirmed in 2018, ...

A fleet of NASA space telescopes has traced a brief flash of gamma rays to a likely collision between two neutron stars, placing the violent event inside a tiny, gas-shrouded galaxy that had escaped ...

TUCSON, Ariz. (KVOA) - The Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing a transformation visible from the southern hemisphere. This change is due to a ...

NASA has released a new composite image of two spiral galaxies, NGC 2207 and IC 2163, as they begin a multi-billion-year process of merging into a single celestial entity. This event was captured with ...

The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s ...

This artist’s impression shows two tiny but very dense neutron stars at the point at which they merge and explode. ESO/L. Calçada/M. Kornmesser, CC BY Billions of light years away in a remote part of ...
