Fireworks in the early universe
Galaxies in the early universe grew fast by rapidly making new stars. Such prodigious star formation episodes, characterized by the intense radiation of the newborn stars, were often accompanied by...
View ArticleFirst 'bone' of the Milky Way identified
(Phys.org)—Our Milky Way is a spiral galaxy—a pinwheel-shaped collection of stars, gas and dust. It has a central bar and two major spiral arms that wrap around its disk. Since we view the Milky Way...
View ArticleAstronomers measure nearby Universe's 'cosmic fog'
Researchers from the Laboratoire Leprince-Ringuet (CNRS/École Polytechnique) have carried out the first measurement of the intensity of the diffuse extragalactic background light in the nearby...
View ArticleAstronomer creates computer models that help explain how galaxies formed and...
(Phys.org)—When most people think of astronomers, they envision scientists who spend time peering at stars and galaxies through telescopes on high mountain tops. Rutgers astronomer Rachel Somerville...
View ArticleGalaxies the way they were
(Phys.org) —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...
View ArticleALMA detects signs of star formation surprisingly close to galaxy's...
(Phys.org) —Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered signs of star formation perilously close to the supermassive black hole at the center of...
View ArticleDiscovery of a blue supergiant star born in the wild
A duo of astronomers, Dr. Youichi Ohyama (Institute of Astronomy and Astrophysics, Academia Sinica or ASIAA, Taiwan) and Dr. Ananda Hota (UM-DAE Centre for Excellence in the Basic Sciences or CBS,...

(Phys.org) —Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.

(Phys.org) —Scientists will seek to gain answers to these questions with the launch of the Cosmic Infrared Background ExpeRIment (CIBER) on a Black Brant XII suborbital sounding rocket between 11 and...
View ArticleAstronomers spy on galaxies in the raw
(Phys.org) —A CSIRO radio telescope has detected the raw material for making the first stars in galaxies that formed when the Universe was just three billion years old—less than a quarter of its...
View ArticleAstronomers gain new knowledge about early galaxies
The early galaxies of the universe were very different from today's galaxies. Using new detailed studies carried out with the ESO Very Large Telescope and the Hubble Space Telescope, researchers,...
View ArticleFeeding galaxy caught in distant searchlight
An international group of astronomers that includes UC Santa Barbara astrophysicist Crystal Martin and former UCSB postdoctoral researcher Nicolas Bouché has spotted a distant galaxy hungrily snacking...
View ArticleThe answer is blowing in the intergalactic wind
Astronomers from the University of Toronto and the University of Arizona have provided the first direct evidence that an intergalactic "wind" is stripping galaxies of star-forming gas as they fall into...
View ArticleThe cosmic evolution of galaxies
Our knowledge of the big bang has increased dramatically in the past decade, as satellites and ground-based studies of the cosmic microwave background have refined parameters associated with the very...
