Intergalactic ‘stream of stars’ 10 times longer than the Milky Way is the 1st of its kind ever spotted
The intergalactic stellar stream (highlighted) was spotted in galaxy cluster 231 million light-years from Earth. (Image credit: William Herschel Telescope/Román et al.) Astronomers have accidentally discovered the first known intergalactic trail of stars. The gigantic “stellar stream,” which is around 10 times longer than the Milky Way, suggests that more of these structures could be…

What are radio galaxies?
A radio galaxy is a galaxy that dominates the sky over Earth in radiowaves. These bright radio wave emissions come from billowing lobes of gas that extend far beyond the visible structure of the galaxy, often for millions of light-years. These radio lobes usually occur in pairs and are created when the heart of a…

Pounding out the dents: Westphall’s career solved problems, advanced discovery – Morgridge Institute for Research
Mike Westphall Whether he was replacing crash-damaged panels on a 1974 Buick as a teenager or devising novel instruments to stretch the capabilities of mass spectrometry to enable examination of some of life’s tiniest particles, Mike Westphall brought a body-shop ethic to work. And those same values of hard work, persistence, and problem-solving influenced Westphall’s…
