Day to day here on Earth, our biggest threat from space is probably some undetected asteroid smashing into us, but astrophysicists looking at the universe on a much larger scale warn that another kind of collision could also impact our planet in the distant future.

To find food, dazzle mates, escape predators and navigate diverse terrain, birds rely on their excellent color vision.
“Humans are color-blind compared to birds and many other animals,” said Mary Caswell Stoddard, an assistant professor in the Princeton University Department of Ecology and Evolutionary Biology. Humans have three types of...
Phantom ships that appear to be sailing in circles off the coast of San Francisco have been discovered by an analyst examining vessel tracking data. Bjorn Bergman, from SkyTruth and Global Fishing Watch, has identified nine boats broadcasting signals that suggest they were around Point Reyes, northwest of the...
New fossils of an ancient legged snake, called Najash, shed light on the origin of the slithering reptiles.
The fossil discoveries, revealed in Science Advances , provide details about how the flexible skull of snakes evolved from their lizard ancestors- and analyses of the family tree have also revealed they...
A team from the University of Cambridge used the mass, radius, and atmospheric data of the exoplanet K2-18b and determined that it's possible for the planet to host liquid water at habitable conditions beneath its hydrogen-rich atmosphere. The results are reported in The Astrophysical Journal Letters.
The exoplanet K2-18b, 124...
Dilophosaurus, a dinosaur made famous by Jurassic Park that lived 183 million years ago, was 'bigger and more powerful' than the movie made it appear, study shows.
From movies to museum exhibits, the dinosaur Dilophosaurus is no stranger to pop culture. Many probably remember it best from the movie...
Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series, the study also describes a new approach for...
The smallest conceivable length of time might be no larger than a millionth of a billionth of a billionth of a billionth of a second. That's according to a new theory describing the implications of the universe having a fundamental clock-like property whose ticks would interact with our best...
(Reuters) - British scientists have created what they believe is the world’s smallest Christmas card, a seasonal greeting so tiny that over 200 million of them could fit into a standard postage stamp. The card, created by the National Physical Laboratory (NPL), the U.K.’s national measurement standards laboratory,...
Independent weather researcher Mila Zinkova is raising the question of whether the aurora borealis played a role in the events that led to the sinking of the Titanic. In her paper published in the journal Weather, Zinkova suggests it is possible that the aurora borealis interfered with navigational systems,...
