News Stories relating to "asteroid"
Wednesday, December 10, 2014
Earth seems to have had a number of lucky escapes recent years; several asteroids have passed uncomfortably close to our home planet, and one exploded without warning in 2013 over Chelyabinsk in Russia, causing injuries to residents and extensive damage to buildings.
Now another piece of space debris has been identified as a...

The question of whether life ever existed on Mars has inspired scientists - and songwriters - for decades. The Red Planet is currently an arid, icy desert where no sign of life remains, but was it always this way?
It is widely recognised that living entities have three basic requirements: standing water, an energy source and the five...

Unknown Country has been keeping a keen eye on the skies just recently, and with good cause: following the revelation last week
that the Earth had narrowly escaped serious damage from 26 very sizeable asteroids over the past few years, another...

The risk of a sizeable asteroid colliding with the earth has always been purported to be extremely low, with scientists reporting that such an event was only likely to occur every twenty million years or so.
Unfortunately, our collective sigh of relief could be a little premature, as recent evidence suggests that, not only is the risk...

Astronomers are warning us that asteroid 2014 DX110 is on target to hurtle between the Earth and the Moon on Wednesday, passing close to our planet at a distance of just 217,000 miles (350,000km).
At 98ft (30m), 2014 DX110 is a relatively large object belonging to the Apollo class asteroid group, a class of Earth-crossing objects...

In the last few hours, a "Deep Impact" style scenario has unfolded in space as a huge asteroid grazed past Earth last night at 27,000mph.
The asteroid passed within 2 million miles of Earth, not exactly a "near miss" but close enough to make scientists sit up and track its progress with more than a passing...

Near-Earth asteroid 2013 NE19, which is about the size of a football field, passed within 2.6 million miles of Earth on July 22. There was no danger that it would strike Earth, but there is a concern because it was discovered just last Monday (July 15). Had it been aimed at Earth, we would have had just eight days to prepare. An object that size...

Asteroid 2013 LR6 will pass within 70,000 miles of Earth tonight, making its closest approach over Tasmania at 9:42 Pacific Time. The asteroid is 30 feet in diameter and NASA says it has no chance of striking our planet. What is a matter for concern, though, is that it was just discovered two days ago, on June 6. The discovery was made by NASA...

NASA plans to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. Is this part of NASA's search for potential "killer" asteroids?
At a recent Congressional hearing, NASA told lawmakers that it's time for...

That's the (rather unscientific) advice to Congress from NASA chief Charles Bolden, who basically says that if a large asteroid heads towards a big US city--as it recently did in Russia--there's not much else we can do. He told them, "From the information we have, we don't know of an asteroid that will threaten the population of the United...

It's like a video game in the sky: A joint mission between Europe and the US plans to slam a spacecraft into an asteroid in order to prove that incoming space rocks can be knocked off their paths before they collide with Earth.
The Asteroid impact and Deflection Assessment mission (AIDA) will intercept the asteroid Didymos in 2022,...

Will life on Mars go the way of the dinosaurs before we have a chance to discover it? Incoming Comet C213/A1, discovered on January 1st, is expected by some astronomers to pass within 28,000 miles of Marsin 2014. But cometary trajectories change, and an impact is not impossible, although NASA estimates that the object will pass Mars at a distance...

An aerospace and physics researcher has a plan to deflect a killer asteroid
by using paint. The idea may sound crazy, but he's working with NASA on the project.
Dave Hyland thinks that one possible way to avert an asteroid collision with Earth is by...

As Asteroid 2012 DA14 approached Earth, a significant meteor strike took place in central Russia. Most experts do not believe that the two events were related, and NASA has confirmed that the asteroid has not broken up. However, smaller debris is sometimes present near asteroids, and is not generally detectable, so it is possible that such debris...

Asteroid impacts are rare, but they can cause incredible harm
(look what one did to the dinosaurs
!). In 1908, one of them flattened 800 square miles in the...

That asteroid that hit the earth 13,000 years ago was a killer, all right--it triggered an ice age that wiped out most of the large animals on Earth. Melted glass buried deep within the Earth at sites around the world confirms the theory that a comet or meteor was responsible.
In the June 12th edition of the Los Angeles Times, Thomas...

A new gold rush is on! Google executives Larry Page and Eric Schmidt (along with filmmaker James Cameron) are backing a plan to mine gold and other precious metals
They've formed a company called Planetary Resources, which will start out by developing...

When US astronauts planted an American flag on the moon, it made other countries nervous because it seemed as if our country might be "claiming" it. Now space lawyers say that the international legal system must be improved and expanded before any products that are...

NASA may return to space after all--but not to explore, to MINE the valuable minerals that are on asteroids, in a NEW TYPE of "Gold Rush." And we may use robots to do the dirty work.
Space scientists think that robots will be the astronauts of the future. They'll explore the universe, find and identify...

Asteroid 255 YU55 will pass between the earth and the moon on Tuesday. The object is the larger than an aircraft carrier and would cause significant damage if it struck either our planet or the moon...

A group of scientists want to capture a near-earth asteroid and bring it closer to Earth, so we can use it as a platform for future space missions. This is not some wild future speculation
: We already have the technology to do this.

We recently had a close call
, and it turns out that the UK is one of the most vulnerable places on Earth, when it comes to an impact
from a space rock. Experts there have created a chart...

An asteroid the size of a city bus had a close call with earth on June 27th. The flyby was so close that it came nearer to us than some satellites are. LiveScience.com, Tariq Malik reports that the arriving space rock came closest to earth just after 1 pm Eastern Time, when it came within 7,500 miles of hitting us. Astronomers saw it coming on...

Comets make people crazy, and with the 2012 end-of-the-world scenario
in people's minds (NOTE: Subscribers
can still listen to this show), the hype surrounding a minor cometary body called Comet Elenin is approaching a...

Astrobiologist Richard B. Hoover has discovered evidence of microfossils that resemble bacteria in fresh (so they couldn't have become contaminated later) slices of the interior surfaces of 3 carbon-filled meteorites
. After looking at them under an electron...
