Can Humans Live in Space Without Going Crazy?  

On May 5, 1961, Alan Shepard became the first American in space when he piloted the Mercury capsule Freedom 7. His sub-orbital journey lasted 15 minutes. Like most children who grew up in the early era of space flight, I remember this moment well. The flight was extra special for me because my dad, Arthur L. Levine, worked for NASA. As a human resources administrator, he recruited John Glenn, who in 1962 became the first American to orbit Earth. My dad, Glenn and Neil Armstrong, all work

Magnetic Fields May Be to Blame for Jupiter's Skin-Deep Stripes  

What would Jupiter be without its stripes? The Great Red Spot might be Jupiter's most famous feature, but the giant planet would be unrecognizable without the multicolored bands streaking across its face. The colors are there thanks to the chemistry of Jupiter's atmosphere, but the striped pattern itself comes from long-lived winds called zonal flows that blow east-west around the planet in alternating directions. These zonal flows are similar to the jet streams high in Earth's atm...

Livestock Infected with Worms Belch and Fart 33% More Methane  

It's estimated that 40% of greenhouse gas emissions come from agriculture, and a substantial portion of that is directly 'emitted' by livestock. And just last year, climate scientists reported that we've actually been underestimating the extent to which the combined belches and flatulence of farmed animals contributes to climate change by 11%. Unsurprisingly, there's been renewed interest in reducing those emissions, especially considering the demand for livestock is only growing. Now, ...

Did Native Americans Breed Parrots in New Mexico 1,000 Years Ago?  

Native Americans may have kept a breeding colony of scarlet macaws in the American Southwest starting more than 1,000 years ago, a new study finds. The birds were raised for their colorful plumage hundreds of miles from their native jungles. With their brilliant red, yellow and blue plumes, scarlet macaws are likely the best-known parrots of the New World. These birds normally range from South America to eastern coastal Mexico and Guatemala. Yet, over the years, archaeologists have une

Utah Pterosaur Was Desert-Dwelling Badass...Pelican?

It belonged to a Late Triassic pterosaur that may have been the biggest of its time. Describing its size, features and home turf, researchers reveal this new Utah pterosaur is full of surprises. Pterosaurs lived at about the same time as dinosaurs, from the late Triassic until the end of the Cretaceous, or roughly  215-66 million years ago. But these fantastic fly...

Well, it looks like we're going to have to look farther than we thought for intergalactic extraterrestrial life. Astronomers have long held out hope that Omega Centauri, a massive globular cluster just 16,000 light years away, harbors habitable exoplanets. Researchers estimate that 10 million densely packed stars lie within the cluster's borders, so statistically speaking, it must house some habitable planets, right? Wrong.

NASA's 60-Year Race to Touch The Sun  

We often equate light with a lack of mystery. We elucidate or illuminate answers. So it's tad ironic that the brightest object in our solar system remains one of its most mysterious. Scientists still don't understand why the sun's corona, or atmosphere, is hotter than its surface — or why the solar wind accelerates as it races away. We have theories: Nearly invisible nanoflares blow out heat. Waves of electrically conductive, fluid-like plasma transfer energy to other twist...

Who's A Good Fox? Soviet Experiment Reveals Genetic Roots Of Behavior

This event occurs during the Northern Hemisphere summer, so even many people who don't consider themselves astronomers venture outdoors to watch it.

Astronomers Watch a Dying Star Enjoy One Last Spark of Life  

Often when stars die, they go out with a bang in the form of a supernova, leaving a small, dim stellar corpse in the center of a gaseous nebula. But sometimes, these leftover stars can get a new spark of life. Astronomers used a telescope in the Canary Islands to watch a dying star, dubbed HuBi 1, get a brief second wind. And as they observed, they noticed a strange side effect: a shockwave sent from the fading star struck the surrounding gas in a way that made it appear "inside out." ...

However, not all planets make it that far. Sometimes, two nascent planets catastrophically collide — and stars apparently do not mourn their dead.

Dust on Mars Likely Comes From Massive Volcanic Deposit  

As luck would have it, Mars will remain engulfed in a colossal dust storm as it reaches opposition on July 27. The viewing conditions might be abysmal, but astronomers can at least take solace in a long-awaited Martian mystery being solved — where all of this dust is coming from. New research published in the journal Nature Communications revealed that the massive amounts of dust are tied to Mars' Medusae Fossae Formation (MFF), the largest explosive volcanic ash deposit in the sola...

Vast Lake Of Liquid Water Discovered On Mars  

Astronomers have discovered a large underground lake of liquid water lurking just below the surface of Mars. The find could end a more than century-long debate over whether or not the Red Planet still has liquid water. The newfound lake stretches some 12 miles from end-to-end, and was discovered using a radar instrument called MARSIS on board the European Space Agency's Mars Express spacecraft, which first reached Mars nearly 15 years ago. The results were published Wednesday in the jou...

The parasite Toxoplasma gondii infects more than 2 billion people — that is, more than a quarter of the world population. The protozoans can live in many warm-blooded creatures, where they reproducing asexually, but they ultimately wa...

Nazis And Dead Dogs: Spaceflight Before The Space Race  

In October 1957, a basketball-sized metallic sphere began circling Earth, transmitting a beacon from above. For many, the launch of Sputnik 1 heralded in the Space Age. But lost often in the story of Sputnik, the Space Age, and the Space Race is that Sputnik wasn't the first spaceflight, and that the first image of Earth from space didn't come in the 1960s, but the 1940s. The actual first spaceflight is a matter of debate. The Air Force defines space as starting at 50 miles (80 k...

To Understand Fossils, These Paleontologists Are Making Faux-ssils  

To learn more from fossils they find in nature, paleontologists are trying to create their own. For decades, paleontologists have been experimenting with heat, pressure, and other factors to mimic nature's ability to preserve the bodies of living things as fossils. Trying to copy fossilization in a laboratory would allow paleontologists to better understand the process and learn more about the history of life on our planet from the fossils they find.

Today, the moon is about as inhospitable to life as it gets. The little water that's there is trapped in ice or rock. It's otherwise dry and airless, fluctuating in temperature by hundreds of degrees anywhere the sun shines. But long ago? That's an entirely different story. New research published in Astrobiology suggests that the moon may have been shockingly habitable in the past during at least two periods — shortly after the moon formed, and when volcanic activity was at its hi...
