Space, Milky Way Galaxy | featured news

Scientists have located a galaxy that gives births to more stars in a day than ours does in a year. Astronomers used NASA's Chandra X-Ray telescope to spot this distant gigantic galaxy creating about 740 new stars a year. By comparison, our Milky Way galaxy spawns just about one new star each year.

Hubble space telescope observations suggest that another large galaxy will collide with our own Milky Way in about 4 billion years.

Astronomers hunting for rocky planets with the right temperature to support life estimate there may be tens of billions of them in our galaxy alone.

The more astronomers look for other worlds, the more they find that it's a crowded and crazy cosmos. They think planets easily outnumber stars in our galaxy and they're even finding them in the strangest of places... "We're finding an exciting potpourri of things we didn't even think could exist," said Harvard University astronomer Lisa Kaltenegger, including planets that mirror "Star Wars" Luke Skywalker's home planet with twin suns and a mini-star system with a dwarf sun and shrunken planets.

The Milky Way galaxy may be filled with millions upon millions of Jupiter-sized planets that have escaped their solar systems and are wandering freely in space, researchers said Wednesday in a finding that seems certain to make astronomers rethink their ideas about planetary formation.

Scientists discovered two bubbles of energy erupting from the center of the Milky Way galaxy.

NASA's Cassini spacecraft buzzed Titan last year, coming close enough to taste the Saturnian moon's atmosphere. The data acquired has implications for our understanding of life throughout the galaxy, as well as Earth's own past.
