Our First Glimpse Of A Quadruple-Star System In The Making

Multiple star systems containing two or more stars are extremely common, but astronomers aren't entirely sure how these complex systems are created. The remarkable discovery of an embryonic four-star system is providing some tantalizing clues. » 2/12/15 6:30am 2/12/15 6:30am

An Over-stuffed Galaxy Slows Down Star Production

Every time we think we have galactic dynamics figured out, the universe throws a new curveball at us. In a new image, two galaxies consumed a conspicuously-absent third. Galactic cannibalism is nothing new, but its chilling impact on star formation is. » 12/08/14 7:07am 12/08/14 7:07am

Peeking In On A Protostar and A Not-Quite-Star Hiding In Clouds of Chaos

What happens when you take observations of a gas cloud, a protostar, and a pre-star dense core of gas, and model them with turbulence? A downright hypnotizing model at how multiple star systems may form. » 8/08/14 4:01am 8/08/14 4:01am

This is the oldest star that astronomers have ever discovered

An international team of astronomers has identified the earliest known star in the Universe. Considered a "second generation star," it formed shortly after the Big Bang — some 13.7 billion years ago. » 2/10/14 12:00pm 2/10/14 12:00pm

The Most Distant Galaxy Ever Discovered

Astronomers have discovered the most distant galaxy yet — a celestial object whose light took an astounding 13.1 billion years to get here. It’s less than 2% the mass of the Milky Way, but it’s producing stars at a rate that’s confounding scientists. » 10/23/13 3:40pm 10/23/13 3:40pm

The Earth's most powerful telescope goes online next week

We are about to see what happens when stars come to life. On March 13, the Atacama Large Millimeter/Sub Millimeter Array (ALMA) goes online. It's the most powerful such telescope ever built, and is part of a class of "very large telescopes" that combine the power of several massive antennae to gather information… » 3/08/13 5:00pm 3/08/13 5:00pm

The lights in the universe are going out. Now astronomers think they…

The universe just isn't what it used to be. Billions of years ago, when the universe was still in its infancy, the casual observer would have seen stars forming all around him, and at a pretty rapid clip. In recent years, however (i.e. the last few billion), the rate of star formation has slowed to a fraction of its… » 8/23/11 12:00pm 8/23/11 12:00pm

Stars burst out of a nebula, like the Genesis Device come to life

If you've ever wanted to see how a nebula's gas and dust can provide the fuel for stars to burst into being, check out this vibrant new Hubble Space Telescope image that hints at the volatility of the early universe. » 7/08/10 4:30pm 7/08/10 4:30pm

Three-Part Nebula Offers A Glimpse At The Inner Workings Of A Star…

This nebula is called the Trifid Nebula, so named for how the dark band of gas separates it into three parts. But this image of the three-lobed nebula reveals another threesome: the three stages of early star formation. » 8/26/09 4:00pm 8/26/09 4:00pm

Black Hole Shoots Pink Jet Of Death

A supermassive black hole is blasting a powerful jet, smashing a nearby galaxy in the system known as 3C321, NASA says. The jet's unprecedented "galactic violence" could wreak destruction on any planets in its path, and could create a burst of new stars. Image by AP/NASA. » 12/20/07 10:15am 12/20/07 10:15am
