NASA put the odds at 3.1%, then back down to 1.5%

(Newser) - Well, nevermind. The day after NASA put the odds of an asteroid collision in 2032 at 3.1%, additional analysis was carried out and as of Wednesday the odds were back down to 1.5%, CBS News reports. With the latest estimate, NASA said it "expects the impact probability...

Chances of Asteroid Hitting Earth in 2032 Just Went Up

There's now a 2% chance of impact

(Newser) - The chances of a large asteroid slamming into Earth in 2032 have gone up but it's still far too early for 2024 YR4 to be a major worry, astronomers say. The European Space Agency says there is now a 2% chance of the asteroid hitting on Dec. 22, 2032,...

Are We All Aliens? Asteroid Samples Yield Ingredients of Life

Bennu samples also indicate it was part of an ancient water world

(Newser) - Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient water world, scientists reported Wednesday. The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were...

Tonight Could Bring Some of 2024's Final Fireballs

Annual Geminids meteor shower is set to peak on Friday evening

(Newser) - The Geminids—among the few major meteor showers to come from asteroids—peak on Friday, one of the year's last chances to see fireballs in the sky. The shower often produces meteors with a distinctly more yellow glow, likely due to the unusual origin material, said Sally Brummel, planetarium...

Scientists to Future Astronauts: Eat Rocks

Organic compounds from asteroids could be fed to microbes, creating 'edible biomass'

(Newser) - Scientists are slowly tackling the roadblocks to human life in space, including how to breathe without oxygen , how to build without bricks , and how to find food where there is none. In terms of the latter, a team from Canada's Western University has come up with what they say...

Spacecraft Launched for 'Crash Scene Investigation'

Hera will take a close look at asteroid rammed by NASA spacecraft 2 years ago

(Newser) - A spacecraft blasted off Monday to investigate the scene of a cosmic crash. The European Space Agency's Hera spacecraft rocketed away on a two-year journey to the small, harmless asteroid rammed by NASA two years ago in a dress rehearsal for the day a killer space rock threatens Earth,...

Earth Will Get a Second 'Mini-Moon' for 2 Months

Small object known as a mini-moon will be temporarily captured in our orbit

(Newser) - The Earth is getting a temporary "mini-moon" for about two months starting later this month. The mini-moon—that's the official astronomical designation—is actually a small asteroid, about 33 feet long, that will be pulled into the Earth's orbit from September 29 to November 25, reports the...

Asteroid Detected Hours Before Earth Impact

It's only the 9th time this has happened

(Newser) - A small asteroid discovered on Wednesday harmlessly burned up in Earth's atmosphere the same day, NASA said. The asteroid—about 3 feet across—was spotted by astronomers in Arizona and broke apart over the coast of the Philippines hours after the discovery. This space rock, dubbed 2024 RW1, is...

Apophis Is Coming, and Scientists Are Scrambling

They have a short window of 4-plus years to plan excursion to asteroid whizzing by Earth

(Newser) - Apophis will not be a surprise visitor—the large asteroid will come close to Earth on April 13, 2029, which just happens to be Friday the 13th, notes the Washington Post . And while nearly five years may sound like plenty of time for scientists to figure out how to get...

NASA Did a Number On the Asteroid It Hit

Dimorphos' shape was changed, in addition to its orbit time, a new study finds

(Newser) - It's safe to say NASA's test of whether an asteroid could be nudged off a collision path with Earth was a success. The DART spacecraft's impact with the asteroid Dimorphos not only shaved 33 minutes and 15 seconds off the time it takes to circle its parent...

NASA Hits the Jackpot on Its 'Rubble Return Goal'

OSIRIS-REx spacecraft returned double the expected samples from asteroid Bennu

(Newser) - NASA finally has counted up all the asteroid samples returned by a spacecraft last fall—and it's double the rubble return goal. Officials reported Thursday that the Osiris-Rex spacecraft collected 4.29 ounces of dust and pebbles from asteroid Bennu. That's just over half a cup and the...

Asteroid Size of Empire State Building Is About to Fly By Earth

2008 OS7 will come within 1.7M miles of our planet on Friday, though experts assure that it won't hit us

(Newser) - An asteroid as big as a skyscraper will pass within 1.7 million miles of Earth on Friday. But it's not on a collision course with us, as it will pass seven times the distance from Earth to the moon, per the AP . NASA's Center for Near-Earth Object...

OSIRIS-REx Reveals a 'Treasure Trove'

NASA finally unlocks long-sought asteroid sample, with some decent-sized rocks

(Newser) - After months of painstaking effort, the last two screws have finally been removed from the end of OSIRIS-REx's articulated arm, which grabbed a sample of the near-Earth asteroid Bennu as part of a $1 billion NASA mission, allowing scientists to look inside. They found a "treasure trove of...

First to Suffer From Asteroid That Doomed Dinos: Plants

Dust particles in atmosphere shut down photosynthesis for 2 years: researchers

(Newser) - It wasn't so much the asteroid impact that killed 75% of the species on Earth some 66 million years ago, but the fact that, for the following two years, little, if anything, could grow. That's according to research offering the first in-depth study of dust particles thrown into...

NASA Capsule Delivers First Asteroid Samples

Rubble was collected from Bennu in deep space

(Newser) - NASA's first asteroid samples fetched from deep space parachuted into the Utah desert Sunday morning to cap a seven-year, $1 billion journey.
