Forget about nukes, dangerous asteroids could be deflected with paintball pellets

No, this isn’t one of those misleading headlines. A MIT graduate student has recently proposed that bombarding an asteroid’s surface with paintballs could throw it off course from a possible collision orbit with our planet, by harnessing solar pressure. The paintball cloud would hit the targeted asteroid and cover it in paint – white paint to […]

Reducing global warming using an asteroid cloud dust

According to the UN Intergovernmental Panel on Climate Change, climate change models suggest that average global temperatures will likely rise by 2 to 11.5 degrees F (1.1 to 6.4 degrees C) by the end of this century. The consequences of an increase of just a few degrees are dire. Apparently, taking clear and effective steps […]

NASA's Dawn spaceship departs Vesta asteroid, heads for Ceres

It’s one asteroid down and one to go, for NASA’s Dawn spacecraft. After spending a year studying the Vesta asteroid and retrieving valuable information to Earth, Dawn is now ready to head for its next destination: Ceres. A different world Scientists expect Ceres to be very different from Vesta. Ceres is considered to be the […]

NASA: students will name asteroid which might head for Earth in a century

While NASA gives all sort of fun names to missions, projects, telescopes – asteroids is not their slickest field. Names like (101955) 1999 RQ36 don’t exactly roll off the tip of your tongue. This is why the people at NASA decided to hold a contest for students, which will decide how an asteroid will be […]

First private space telescope is set to safeguard humanity from asteroid threats

There are millions of asteroids currently residing in our Solar System, of which some 500 thousand orbit in the inner solar system, where our planet also lies. Space agencies in the world have only mapped so far a mere 1% of these. Clearly, an asteroid impact with Earth poses a serious and realistic threat to […]

No more worries - computer simulation shows nuclear bomb can save Earth from an asteroid

The plot of the Hollywood blockbuster flick Armageddon is fairly simple – a giant asteroid is hurling towards Earth, threatening to obliterate all life on the planet as we know it. A team of brave oil-drillers is sent on the space rock to diffuse the threat by detonating a nuclear warhead placed inside the asteroid itself. Apparently, a group […]

Comet might have catastrophically collided with Earth 13,000 years ago

A recently published study suggests that the Earth might have been visited by a giant space rock 13,000 years ago, an event which might have sparked an unusual cold period in the planet’s climate history. The Younger Dryas, also known as the Big Freeze, was a brief period of cold climatic conditions and drought which occurred […]

A large asteroid will pass Earth, closer than Moon

According to NASA, a large asteroid called 2005 YU55 is expected to pass at some 201,700 miles of Earth on Tuesday – closer than the Moon, and definitely closer than the Elenin comet. Now, before people start going all 2012 armageddon on me, let it be said that asteroids often pass at this distance from […]

Half of supermassive black holes are surrounded by 'dust clouds'

Black holes are perhaps the most fascinating and staggering objects in the known Universe, and we are just now beginning to uncover their secrets. Dr. Sergei Nayakshin of the University of Leicester and his team found that doughnut-shaped dust shrouds that cover about half of supermassive black holes may very well be the result of […]

Gamma-ray bursts might cause mass extinction on Earth

Most of us tend to believe the Earth is a safe heaven, with little regard to outerwordly consequences. The truth is our planet, although without a doubt a true gem within our galaxy, is susceptible to a slew of events triggered from within or well beyond our solar system. A lot of them are very […]

NASA maps 93% of all near-Earth asteroids. In other news, Dinosaurs wish they had science.

Armageddon can wait, NASA‘s in charge for a little while longer. The space agency recently released to the general public a report which censuses more than 93% of the total number of asteroids in the vicinity of Earth’s orbit, meaning they’re all tagged and tracked – risk of undetected collision to a minimum. That’s not all either, […]

New dinosaur extinction theory: an ocean of lava

It wasn’t just a devastating asteroid that killed off all the dinosaurs 65 million years ago. Scientists from Boston University now claim that a massive eruption of lava fronts around the world, coinciding with the asteroid impact, sealed their fate forever. The controversial theory is betting on two unusually hot blobs of mantle 1,700 miles […]

NASA's DAWN spacecraft successfully enters Vesta's orbit. Snaps detailed photo

This weekend, NASA‘s DAWN spacecraft finally put a lot of tension and nerves to rest after it successfully entered Vesta’s orbit, the second largest object in the Asteroid Belt. The whole event took place at 1 a.m. EDT Saturday (0500 GMT), marking the first time a man made spacecraft entered the orbit of an object […]

NASA spacecraft set to visit giant asteroid this weekend

After a four year journey, NASA’s Dawn spacecraft will finally reach the orbit of Vesta, the second largest asteroid in our solar system. The object, located 117 million miles from Earth and spanning across a circumference of 329 miles, will be visited in premiere by Dawn this weekend when the latter will hover over on […]

Bus-sized Asteroid barely misses Earth

This Monday (June 27), an asteroid the size of a bus just buzzed our planet after a flyby which brought it closer to Earth than most satellites. Dubbed asteroid 2011 MD, it was first spotted by MIT’s Lincoln Near Earth Asteroid Research (LINEAR) program just last week on June 22, but there never was any […]

NASA to collect samples from near-Earth asteroid

NASA announced that it will launch an unmaned ship to a nearby asteroid, in an attempt to figure out more about both the asteroid itself, and how life started on our planet. The mission, named Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer – or, as always, with an easier more manageable name, Osiris-Rex was chosen to take place […]

Stalker asteroid could be Earth's close relative

Astronomers from the the Armagh Observatory in Northern Ireland declared that a recently discovered asteroid has been following our planet in the past 250.000 years, and it may be in fact closely related to Earth. Two months after it was discovered with the WISE survey satellite, the asteroid caught the attention of two scientists: Apostolos […]

Huge asteroid to pass near Earth in November

Researchers and astronomy amateurs alike should leave a few days open in their November calendar and prepare for something awesome; one of the major and potentially perilous (in time) asteroids will be making a flyby this year. The asteroid, 2005 YU55 is a round small world with a diameter of 400 meters. The asteroid will […]

NASA rejects Russian report: Apophis asteroid extremely unlikely to hit earth

In 2004, NASA researchers identified the Apophis asteroid and after some quick calculations they states there is a chance the asteroid will hit our homey planet in 2029. A few observations and some other calculations later, they explained that that chance is extremely small for 2029, as well as other years to come. However, reports […]

Japanese probe returns home with asteroid dust

JAXA, the Japanese space agency is becoming more and more active these days, as Japanese researchers are getting involved in more and more ambitious projects. Recently, a probe they sent out returned home with grains of dust gathered from an asteroid, a feat without precedent in history. The finding could provide valuable insight into the […]

How to deflect an asteroid with today's technology

An asteroid threat to Earth seems like something we are going to have to face, sooner or later – and people are starting to aknowledge this fact; take Apollo 9 astronaut Rusty Schweickart for example. He is among a group of people that are championing the need to be prepared in case of such an […]

The 8 coolest ways the Earth might be destroyed

We’ve all seen at least one movie in which our planet is destroyed, but most of them were quite repetitive and kind of uninteresting. Our planet deserves so much more! Black holes Well, it seems the more we understand things about black holes, the more we find out things we don’t know, and the more […]

Life had a big rebound following marine mass extinction event

In 1980, Luis Alvarez and his team shocked the whole world when they announced their theory that an asteroid impact that took place 65 millions years ago was responsible for the extinction of the dinosaurs and much of that time’s living organisms. Despite the fact that they delivered substantial evidence, there are still some minor […]

First firm prediction of an incoming space rock confirmed

A very small asteroid exploded over the continent of Africa this week, confirming the prediction of astronomers. Despite the fact that nobody has seen and photographed the asteroid due to the fact that it entered in a very remote area, it was detected with an infrasound array in Kenya; it exploded without striking the Earth.
