The Gravitational Wave Detectors Are Turning Back On and We're Psyched

The LIGO and Virgo gravitational wave detectors are set to resume their hunt for gravitational waves on April 1. This go-around, they’ll be even more sensitive thanks to a set of upgrades to their lasers, mirrors, and other components. This next run will be a big deal—for different reasons than the first two…Read more...

Apparently even NASA is wrong about which planet is closest to Earth

Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?Wrong! Neither Venus nor Mars is the right answer. Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury! Did Musk pick the wrong planet to die on? By 2024, Elon Musk wants to land humans on Mars – the billionaire entrepreneur has said that he himself wants to go to the Red Planet, and even wants to die there (just not on impact, he qui...

The birth of exoplanetary science

The University of Geneva’s Michel Mayor and his graduate student Didier Queloz were the first to discover a planet orbiting a distant star much like our own Sun. Meticulously ruling out, one after the other, alternative interpretations of their measurements, in October 1995 they announced the discovery of the planet designated 51 Pegasi b, now known as Dimidium, orbiting the star 51 Pegasi, since named Helvetia. Michel Mayor presented the discovery to an international assembly of astrophysicists...

Physicists Propose Hunting for Signs of Dark Matter in Ancient Minerals

Physicists typically build large, complex experiments to hunt for dark matter particles coming from outer space, but what if clues to its existence have been hiding inside the Earth all along? One group of physicists proposes hunting for signs of it in ancient minerals, such as olivine or gypsum, that formed in the…Read more...

Gaze in Awe at Hubble's Most Detailed View of the Triangulum Galaxy

Usually when astronomers talk about our neighboring galaxy, they’re talking about Andromeda, which is a cozy 2.5 million light-years away. But just a little farther—okay, 500,000 light-years farther—is another spiral galaxy, the third largest in our local group. Hubble has just released its most detailed view yet of…Read more...

Laser "porch light" could be a beacon for ETs

A feasibility study in the Astrophysical Journal explains how a powerful laser on an Earth mountaintop, focused through a huge telescope, could shine a light of infrared radiation that would be detectable up to 20,000 light years away. While some scientists are concerned about alerting extraterrestrials to our presence, I agree with what something said to me by Ann Druyan -- co-writer of Cosmos and many other works with her husband Carl Sagan -- when we were working on the Voyager Golden Record:...
