With a new (and hopefully final) "Planet of the Apes" movie about to open across the USA in 2017, we thought it would be interesting to take a fresh look at the theory subscribed to by Carl Sagan and the... Continue reading

There’s no doubt that receiving the first message from an extraterrestrial civilization will be historic. But what would be the next step? Dan Werthimer directs the search for extraterrestrial intelligence, or SETI, at the University of California, Berkeley. He says... Continue reading

Forget the popcorn. What will happen to Earth when, in a few billion years' time, the Sun is a hundred times bigger than it is today? Using the most powerful radio telescope in the world, an international team of astronomers... Continue reading

The great British physicist Sir Roger Penrose likes to say that the human brain is more complex than our Milky Way Galaxy. Why are we the only species that evolved to have the ability to invent the radio, scan the... Continue reading

The ice sheet covering Greenland is four times bigger than California—and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. New field-based data suggests that during major climate cool-downs in the... Continue reading

ASA's Cassini spacecraft has sent to Earth its first views of Saturn’s atmosphere since beginning the latest phase of its mission. The new images show scenes from high above Saturn's northern hemisphere, including the planet's intriguing hexagon-shaped jet stream. Cassini... Continue reading

A substantial coronal hole began to rotate into view over the past few days (Dec. 1 - 2, 2016). Coronal holes are magnetically open areas of the sun's magnetic field structure that spew streams of high speed solar wind into... Continue reading

A recent study from ESA's Mars Express and NASA's Mars Reconnaissance Orbiter (MRO) provides new evidence for a warm young Mars that hosted water across a geologically long timescale, rather than in short episodic bursts – something that has important... Continue reading

Forty-thousand tons of cosmic dust falls to Earth each year. These particles that have been around since the formation of our solar system have been found for the first time on rooftops in three of the world's major cities. These... Continue reading

After months of speculation and rumor, NASA released its long-awaited research paper on the controversial EM Drive propulsion system. The paper was recently published in the American Institute of Aeronautics and Astronautics' peer-reviewed Journal of Propulsion and Power. If the... Continue reading

Scientists have gained fresh insight into the nature of dark matter, the elusive material that accounts for much of the mass of the Universe. Calculations based on a study of distant galaxies, using powerful ESO telescopes, suggest that dark matter... Continue reading

"The mystery of why we haven't yet found signs of aliens may have less to do with the likelihood of the origin of life or intelligence and have more to do with the rarity of the rapid emergence of biological... Continue reading

On November 30th, for the first time, participants around the world took part in a unique worldwide experiment with the aim of testing the laws of quantum physics. Twelve laboratories from around the world collaborated in quantum experiments powered by... Continue reading

"The question of whether advanced civilizations exist elsewhere in the universe has always been vexed with three large uncertainties in the Drake equation," said Adam Frank, professor of physics and astronomy at the University of Rochester. "We've known for a... Continue reading

The physicist Neils Bohr once said to a colleague, "your theory is crazy, but it's not crazy enough to be true." For many scientists, the most exciting result of the LIGO discovery of gravitational waves is that astronomy can now... Continue reading

What will it take to survive on Mars? To find out, Neil deGrasse Tyson interviews Andy Weir, best-selling novelist and author of The Martian, which was adapted into a feature film starring Matt Damon as astronaut Mark Watney and received... Continue reading

Galaxies are usually grouped into clusters, huge systems comprising up to thousands of millions of these objects, in whose interior are found the most massive galaxies in the universe. Until now scientists believed that these "supergalaxies" formed from smaller galaxies... Continue reading

Alpha Centauri, our nearest star system, is taking back its ancient moniker, Rigil Kentaurus, which means “foot of the centaur” in Arabic, according to Science, the online publication of the American Association for the Adancement of Science (AAAS). The newly... Continue reading

“Life can tolerate a lot of stuff: It can tolerate a lot of salt, extreme cold, extreme heat, says William McKinnon, professor of earth and planetary sciences at Washington University. "But I don’t think it can tolerate the amount of... Continue reading

"This is different from what we see in the nearby Universe, where galaxies in clusters grow by cannibalizing other galaxies. In this cluster, a giant galaxy is growing by feeding on the soup of cold gas in which it is... Continue reading

Around 75 years ago, Italian physicist Ettore Majorana hypothesized the existence of exotic particles that are their own antiparticles. Since then, interest in these particles, known as Majorana fermions, has grown enormously given that they could play a role in... Continue reading

As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world's weather patterns abruptly transformed the vegetated region into some of the driest land on Earth. A... Continue reading

On Sept. 14, 2015, LIGO's detectors made the very first direct detection of gravitational waves, just two days after scientists restarted the observatory as Advanced LIGO—an upgraded version of LIGO's two large interferometers, one located at Hanford, Washington, and the... Continue reading

"Truly autonomous fleets of robots have been a holy grail in oceanography for decades," Thompson said. "Bringing JPL's exploration and AI experience to this problem should allow us to lay the groundwork for carrying out similar activities in more challenging... Continue reading
