Astronomers discover galaxies have bipolar gas outflows reaching far into intergalactic space
Gas outflows (red) near spiral galaxies (white). The left image shows the outflow of gas for the group of galaxies we see edge on. It is clear that most of the gas escapes upward and downward into intergalactic space. The right image shows the galaxies we see face on. A ring of gas is visible…

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…

One of the brightest stars in the sky will ‘blink out’ on Dec. 12. Here’s how to watch.
Next week, a rare celestial event will occur as an asteroid blocks the red supergiant star Betelgeuse in the constellation Orion. Betelgeuse, usually the 10th-brightest star in the night sky, will briefly blink off Monday, Dec. 11 as the asteroid 319 Leona appears to pass in front of it from our point of view on…

In the Search for Life beyond Earth, NASA Dreams Big for a Future Space Telescope
The first steps to solve the millennia-old mystery of our true place in the universe happened, of all places, on a brisk and early Tuesday morning in the unremarkable conference room of a hotel in Washington, D.C. Here a team of legendary heroes assembled on Halloween—Gandalf and a Star Trek captain among them. Yet these…

A ‘world-first’ telescope allowing Australia to play a starring role in space communications
More than half a century after a tracking station in the ACT’s Namadgi National Park broadcast the grainy footage of Neil Armstrong’s first steps on the moon, a new telescope will allow Canberra to play another starring role in space communications. Key points: A new telescope at Mount Stromlo will give researchers thousands of times more…

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…
