Ancient Galaxy Bursting' with Stars
Most of the early galaxies that astronomers have been able to observe are small with a low-to-moderate amount of star production. But now the Herschel Space Observatory has found a massive dust-filled galaxy churning out stars at an incredible rate, with all of this taking place back when the cosmos was a just 880 million

The Whirlpool Galaxy Like You’ve Never Seen it Before
It's big, it's active, and it's only 20 million lightyears away-- it is the Whirlpool galaxy, and astronomers are getting a brand new view. Using the Plateau de Bure interferometer, this paper examines the gas in this nearby grand-design spiral galaxy on arcsecond scales, resolving for the first time its individual molecular clouds. What does this tell us about star formation in this galaxy? Stay tuned!

Seeing Galaxy formation before reionization: baryon-dark matter relative velocity helps!
Relative velocity in the early Universe between regular matter (baryons) and dark matter enhances an otherwise hard-to-detect signal and makes it likely we can look back even farther into the past.

Wrapping Around The Mystery Of Spiral Galaxy Arms
How disk galaxies form their spiral arms have been puzzling astrophysicists for almost as long as they have been observing them. With time, they have come to two conclusions… either this structure is caused by differences in gravity sculpting the gas, dust and stars into this familiar shape, or its just a random occurrence which

Hubble Uncovers Hidden Mysteries in Messier 77
Discovered on October 29, 1780 by Pierre Mechain, this active Seyfert galaxy is magnificent to behold in amateur equipment and even more so in NASA/ESA Hubble Space Telescope photographs. Located in the constellation of Cetus and positioned about 45 million light years away, this spiral galaxy has a claim to fame not only for being

Galaxies the Way They Were
... other data to study how galaxies form and evolve in the early universe. Credit: NASA/Hubble. Low Resolution Image (jpg)Galaxies today come very roughly in two types: reddish, elliptically shaped collections of older stars, and bluer, spiral shaped objects dominated by young stars. The conventional wisdom is that the two types are related to one another, ellipticals representing an ol
