(Newser) - Almost 500 million years ago in the Ordovician Period, two large bodies in the asteroid belt collided. Two asteroids, or an asteroid and a comet, blew apart and their debris and dust fell to Earth. One of these large bodies was the source of all the L-chondrite meteorites that have...

We Got Earth's Birthday Wrong by 60M Years

Same goes for the moon, say scientists

(Newser) - The planet we're living on is about 60 million years older than previously thought. So say scientists in France who studied quartz from Australia and South Africa that dates back about 3 billion years, reports Phys.org . The ratio of gases in the quartz compared to today's ratios...

The result is a dense system of stars—apparently the densest ever...

Jupiter's Great Red Spot Has Really Shrunk

It looks more like a circle than an oval

(Newser) - The signature red spot we see in pictures of Jupiter could fit three Earths next to each other—in the late 1800s. The Great Red Spot is getting smaller, and the reason is a mystery, Reuters reports. It was some 25,000 miles across in the late 19th century; by...

Tiny 'Fossil Galaxy' Could Hold Clues to Early Universe

Segue 1 apparently stopped evolving 13B years ago

(Newser) - One of our galactic neighbors, the tiny Segue 1, could be among the first galaxies ever to take shape—and it may present an opportunity for scientists to examine our universe as an infant. Segue 1's chemical composition suggests it stopped evolving some 13 billion years ago, Scientific American...

Mars Gets Up Close, Personal With Earth

Red planet is closest it's been to us since 2007

(Newser) - The red planet is coming in for a close-up with our night sky: As Sky & Telescope reports, Mars will be closer to Earth this month than it's been since the end of 2007, appearing bigger and brighter in the night sky for the middle two weeks of April....

Space Junk Solution: Fire Lasers at It

Australia prepares to deal with 300K pieces of debris

(Newser) - Space is full of debris, scientists say—about 300,000 pieces of it—and it's putting our satellites at risk. We could be "a couple of decades away from a catastrophic cascade of collisions ... that takes out all the satellites in low orbit," says researcher Matthew Colless....

Polaris getting brighter over the centuries

(Newser) - Polaris is famed for its consistency, but the North Star we see today is brighter than it was in the 1800s. In fact, if historical records are correct, the star has gotten about 2.5 times brighter over the course of the past two centuries, researcher Scott Engle tells Space....

Hawking's New Theory: 'There Are No Black Holes'

He addresses conflicting theories of physics

(Newser) - Stephen Hawking helped develop current theories on black holes—but now, he's saying there aren't any. New Scientist explains his thinking, focusing on what's known in physics as the "firewall paradox," which deals with a black hole's event horizon. That's an "invisible...

Secrets of Mysterious Black Hole Jets Revealed

Jets have power to spew iron and nickel, study finds

(Newser) - For years, astronomers have wondered what exactly black holes spew into our universe—and now they know. Iron and nickel have been found shooting from the relativistic jets of a black hole several times larger than our sun, but the finding is more surprising than it may seem. It shows...

Olympic Torch Returns From Space

Crew parachutes into Kazakhstan

(Newser) - A Russian space capsule carrying the Sochi Olympic torch and three astronauts returned to Earth today from the International Space Station in a flawless landing on the steppes of Kazakhstan. The Soyuz capsule landed at 8:49 local time, about three and a half hours after undocking from the station...

There Are Billions of Earth-Like Planets in Our Galaxy

At least 8.8 billion planets like ours in the Milky Way, study finds

(Newser) - Space is vast, but it may not be so lonely after all: A study finds the Milky Way is teeming with billions of planets that are about the size of Earth, orbit stars just like our sun, and exist in the Goldilocks zone—not too hot and not too cold...

New Asteroid Points to Habitable Exoplanets

Scientists spot water-rich asteroid 170 light-years from Earth

(Newser) - Scientists have spotted the remains of a water-rich asteroid, orbiting a dying star about 170 light-years from Earth. It's more than a bit of space waste—the find suggests that this far-off solar system may have once had planets capable of supporting life, the LA Times reports. "The...

Work for NASA: Lie in Bed for 15 Weeks

And get paid about $5K a month

(Newser) - Best job ever? NASA wants test subjects to spend 15 weeks in bed and get paid about $5,000 a month for doing it, the Metro reports. Sounds like a dream job (literally), until you realize that you'd be prohibited from sitting or standing up, the Houston Chronicle notes....
