Scientists suspect lightweight dark matter might ionize hydrogen in the Milky Way’s core. This could also explain the 511-keV ...

A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter. Dark matter, the ...

Askew Galaxy Coaxing Star Formation: Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral) Arp 273, the ‘Rose ...

Day 20 of the 2024 Space Telescope Advent Calendar: a galactic chain. This Hubble image features an interacting galaxy system known as Arp-Madore 2105-332, that lies about 200 million light-years ...

This research underscores the complexity of shock-induced processes in interacting galaxy groups like Stephan’s Quintet. The findings highlight the role of shocks in driving energy dissipation ...

We are particularly interested in the role that galaxy environment plays, from the small scale of galaxy mergers and interactions to the large scale galaxy clusters, filaments, and voids. We use ...

Scientists used XRISM to detect hot gas flows in Centaurus Cluster, proving that galaxy collisions cause gas movement and ...

The Milky Way's Central Molecular Zone (CMZ), is unlike most of the galaxy. Almost 80 percent of its dense gas is held there, ...
