Pixar’s The Good Dinosaur hits cinemas this Wednesday, just in time for the Thanksgiving holiday. And who better than Neil de Grasse Tyson to indulge in a bit of playful speculation about the film’s premise: what if the K-T asteroid that wiped out the dinosaurs 65 million years ago had missed Earth? »
We can expect a totally different kind of trick-or-treater this coming Halloween. A rather large asteroid—discovered less than three weeks ago—is set to to fly past the Earth at a distance not seen in nearly a decade.
For nearly 40 years, paleontologists have argued over what really killed the dinosaurs. Was it an massive asteroid impact, or a spate of volcanic eruptions? Or what if a powerful impact ignited volcanoes, walloping Earth’s biosphere with a deadly 1-2 punch?
NASA announced the finalists for its next round of planetary explorations. There were the usual suspects—Venus, Jupiter’s asteroids—and, then, there was this: An asteroid, composed almost entirely of (possibly magnetic) metal, with a crust literally beaten away by interstellar collisions, named Psyche. Pardon? »
We once considered the Sun a planet, and it took finding Uranus to decide that moons should really be their own category of thing. These are all the places in our solar system that were once planets—but now have far more suitable names. »
These grainy radio echoes of a weirdly-shaped asteroid tumbling through a close approach of our home planet are oddly hypnotizing.
In a short, informative video, the American Museum of Natural History explains all the proposals for deflecting asteroids. Sadly, the plan from Armageddon is not on the list. »
Roughly 3.3 billion years ago, Earth’s early life forms were plunged into an unimaginable hell, when a series of massive asteroids smashed into the young planet, vaporizing the oceans and scorching the skies. »
There’s a 1200-foot asteroid headed straight for the Earth. You’ve got five days to come up with a plan, or go the way of the dinosaurs. This isn’t the script for the Day After Tomorrow sequel — it’s the scenario being war-gamed by a roomful of PhDs as we speak. »
As the discoverer of Asteroid 316201, NASA's Amy Mainzer had the right to name the object under the rules established by the International Astronomical Union. So her choice to name the asteroid after Nobel Peace Prize-winner Malala Yousafzai is a truly generous and beautiful gesture. »
On Friday, asteroid 2014-YB35 is expected to make its closest approach to Earth. Traveling at over 23,000 mph (37,000 km/h), NASA says the 6.2 mile (1,000 meter) asteroid won't get any closer than 2.7-million miles (4.4 million km). That's nearly 12 times the distance from Earth to the Moon – so relax. »
Measuring 250 miles (400 km) wide, the now-buried crater in Australia was ground zero for a cataclysmic impact that occurred some 300 million years ago. But is it really the largest on Earth? »
There's a famous line from Shakespeare's Hamlet that says "There are more things in heaven and Earth, Horatio, than are dreamt of in your philosophy," and the same now holds true for brave new worlds for humans to explore. »
Space may look calm and empty from down here, but when you see everything moving around up there, it's actually pretty crowded. »
By using lasers to simulate the impact of a large meteor with primordial Earth, researchers have shown how the atom bomb-like collisions might have reconstituted ordinary molecules into the early building blocks of life. »
Prior to going into hibernation mode, the Philae lander hurriedly conducted a number of experiments and sent its findings back to Earth. Preliminary analysis shows that the icy and dust-covered comet contains organic molecules. It's a cool discovery, no doubt, but one that shouldn't be exaggerated in terms of its… »
An ominous dash-cam video has captured an extraordinarily bright orange flash in Russia's Sverdlovsk region in the Urals. Though the event was witnessed by many onlookers, there's still no explanation for what appears to be a rather massive blast. »
Astronomers tend to assume that the timing of Earth-striking meteors are completely random, but a recent analysis suggests that meteor impacts are more likely to occur at certain times of the year and at certain locations. »
