Deep Impact: From Fantasy to Fact?

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...

Risk from Major Asteroid Strike Higher Than Previously Thought

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...

Close Encounter: Massive Apollo-Class Asteroid Set to Skim Past Earth Tonight

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...

Another Asteroid Near Miss?

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...

Do we now have a date for Doomsday?

Prophets and soothsayers have been predicting the end of the world for thousands of years, with possible extinction-level events cited as super-volcanoes or earthquakes, giant solar flares, pollution, plague and pestilence, and the favourite of the 20th century, nuclear war. There is no doubt that planet Earth is currently under-going what...

Fireballs Rain Down as Another Asteroid Near Miss Takes Place. What's Going On?

We are currently living under very volatile skies. Less than one year after a 10,000 ton meteorite exploded above the Russian city of Chelyabinsk in the Urals injuring 950 people, Russian scientists reveal that a nearby area of the country narrowly missed an impact from a 15 meter asteroid which skimmed past Earth last weekend. The asteroid, which...

Asteroids Bring Life as Well as Death

Besides ending life on planets through impacts, asteroidsmay also spread life throughout the universe. Although thislife is in the form of tiny bacteria which are only thebeginning of a long evolution to intelligent life, it doesmean that most life will be carbon-based, so if we ever domeet aliens we may recognize them. The planet(s) where...

Sun Changes Asteroid Orbits

It's been discovered that the force of sunlight on an asteroid can change its orbit, which is one reason why asteroids change direction and head for Earth. What we don't know is this: Will the increased solar activity on the sun right now have an increased effect on asteroids?

Eugenie Samuel Reich writes in New Scientist that astronomers...

Little Asteroids Can Have Big Impact

It's not just the big asteroids we have to watch out for?the little rocks can be dangerous too. They're hundreds of them out there and they're hard to spot, but NASA has decided it had better start searching for them.

Robert Roy Britt writes in Space.com that it will cost at least $236 million to add a search for small asteroids to their...

Without the Moon, We'd be Dead as Dinos

There are not nearly enough craters on Earth for the large number of asteroids that impact us every year. Over the past 250 million years, Earth should have been hit around 440 times by asteroids larger than a mile across. But scientists have found only 38 large impact craters from this period. Scientists now think that when many of them hit...

Green Meteors May Forecast UFOs

During the 1948-1952 UFO flap, green fireballs kept appearing over the western U.S. These were officially classified as meteors, and appeared in the same general area of the country as the green fireball that was seen last weekend in the West. Many UFO investigators have speculated about a possible connection between the green fireballs and the...

Search for the Fabled Vulcanoids

Astronomers want to find all the asteroids that may be heading for an impact with Earth, so they're searching for the legendary group of asteroids called "Vulcanoids" that may be circling the sun. We can't see these asteroids, but we know they?re there because they effect Mercury's orbit and make the planet wobble. In the 19th century,...

Asteroids Gave Birth to Dinos, Then Wiped Them Out

An asteroid may have wiped out the dinosaurs 65 million years ago, but an earlier one probably allowed the rise of the giant creatures, who dominated the planet for 135 million years. After their demise, mammals took over and eventually evolved into humans, so our domination was caused by an asteroid as well. Will asteroids also bring about the...

Tiny High-Speed Particles Impact Earth

Scientists have decided that two mysterious explosions in the 1990s were caused by mysterious tiny particles from space. The two objects were picked up by earthquake detectors as they tore through Earth at up to 900,000 mph. According to scientists, they were "strangelets," which are clumps of matter that have so far defied detection.

Double Trouble: Asteroids Come in Pairs

When Earth is next hit by an asteroid, the impact may well be doubled, since a new study estimates that 16 percent of asteroids in the region of space shared by Earth's orbit are actually double asteroids, called binaries. Evidence shows that impacts on Earth sometimes involve a pair of craters. Researchers say these pairs may have been created...

Asteroids Could be New Weapon of War

Asteroids could be used to destroy enemy cities if they were nudged out of their normal orbits and guided towards cities on Earth by a string of nuclear explosions.

The result could cause devastation more than 50,000 times greater than the bomb at Hiroshima and could obliterate a region the size of Belgium. The perpetrators might even be...

More Near-Earth Asteroids Found After Near Miss

NASA's Near-Earth Asteroid Tracking System has detected five more near-earth asteroids in the past few days, after a near-miss was recorded over Christmas. While the number of large near-earth asteroids is believed to be between 500 and a thousand, not the 2000 previously estimated, it appears that the overall number of objects may be much...

Solar Storm May Hit, Near-Earth Asteroid Passing

A coronal mass ejection that left the Sun on Monday is likelyto buffet Earth's magnetosphere later this week. Forecasters estimate a 20% chance of severe geomagnetic activity when the CME arrives. Auroras are possible early Thursday and Friday mornings.

A near-Earth asteroid, 2000 YA, has just been detected and will pass within two...
