An international research team led by the Max Planck Institute for Astronomy (MPIA) and involving the University of Bonn has mapped the cold, dense gas of future star nurseries in one of our neighboring galaxies with an unprecedented degree of detail...

Astronomers have been keenly peering into M51, or the Whirlpool Galaxy, since the 1800s, its signature spiral structure informing the earliest debates over the nature of galaxies and the Cosmos at large. But no one – not with the naked eye or with increasingly powerful modern telescopes – has ever seen what Case Western Reserve University astronomers first observed using a refurbished 75-year-old telescope in the mountains of southwest Arizona. “I literally looked at the image and said, ‘What in the world is that?'” said Case Western Reserve astronomy professor Chris Mihos.
What it was turned out to be a massive cloud of ionized hydrogen gas spewed from a nearby galaxy and then essentially “cooked” by radiation from the gala...

This image from Hubble’s Wide Field Camera 3 (WFC3) shows a section of NGC 1448, a spiral galaxy located about 50 million light-years from Earth in the little-known constellation of Horologium (The Pendulum Clock). We tend to think of spiral galaxies as massive and roughly circular celestial bodies, so this glittering oval does not immediately appear to fit the visual bill. What’s going on?
Imagine a spiral galaxy as a circular frisbee spinning ge...
