A new study suggests that dinosaurs were already on their way to extinction before the asteroid strike that led to their ultimate demise.

According to research carried out by scientists at the University of Bristol and the University of Reading, dinosaurs were thriving from the

Two new telescopes could help NASA find 90% of potentially hazardous asteroids

Apr 14

A study has found that using a combination of ground-based and space-based telescopes would significantly increase the discovery rate of potentially hazardous asteroids (PHAs). NASA is legally required to identify at least 90% of asteroids that are 140+ metres in size and that could pose a danger to Earth. When the law was passed by the US Congress a decade ago, the space agency was given a deadline of 2020 to reach that target; however,

How Near-Earth Asteroids Meet Their Fate: New Research A Game Changer

Apr 08

A study conducted by an international research group has found that asteroids meet their fate much farther from the Sun than previously thought. For decades, astronomers believed that the majority of near-Earth asteroids came to the same fiery end: somewhere along the line, they would plunge into the Sun and be destroyed. Now scientists have reached a different conclusion: most NEAs break up long before they reach our central star.

Drilling Into Chicxulub Crater Begins

An expedition to drill into the Chicxulub Crater, believed to be the impact site of an asteroid that wiped out non-avian dinosaurs, is now under way just off the coast of Mexico.

Researchers will make a bid to access the crater’s rock, the key parts of which are buried beneath 600m of ocean sediment. If
