A New Exoplanet May Be Most Promising Yet in Search for Life
Photo An artist’s impression of the newly discovered rocky exoplanet. The exoplanet is close enough that astronomers are hopeful that with the next generation of big telescopes, they will be able to probe its atmosphere for signs of water or other evidence of suitability for life. Credit M. Weiss/CfA A prime planet listing has just appeared on the cosmic real estate market, possibly the most promising place yet to search for signs of life beyond the solar system, the as..>> view originalAstronaut and Cosmonaut Launch to Space Station on Russian Soyuz
An astronaut and a cosmonaut launched on the first two-person spaceflight in 14 years, bound for a 5-month stay on the International Space Station. Astronaut Jack Fischer with NASA and cosmonaut Fyodor Yurchikhin of Roscosmos lifted off on Russia's Soyuz MS-04 spacecraft, atop a Soyuz-FG rocket, from the Baikonur Cosmodrome in Kazakhstan at 3:13 a.m. EDT (0713 GMT; 1:13 p.m. local time) Thursday (April 20). Launched on a "fast-track," six-orbit rendezvous, they are set to dock the Soyuz..>> view originalScientists, Stop Thinking Explaining Science Will Fix Things. It Won't.
Scientists should reconsider how they deploy their knowledge. Photo illustration by Slate. Photo by DragonImages/Thinkstock. If you consider yourself to have even a passing familiarity with science, you likely find yourself in a state of disbelief as the president of the United States calls climate scientists “hoaxsters” and pushes conspiracy theories about vaccines. The Trump administration seems practically allergic to evidence. And it’s not just Trump—plenty of people across the poli..>> view originalThis Planet Around A Small, Cool Star May Be Our Best Shot At Finding Alien Life
M. Weiss/CfA Artist's impression of LHS-1140b around its star. An Earth-like planet orbiting a small, cool star not far from our sun could be the best candidate so far for detecting life.The "super-Earth", a rocky planet about six times the mass of Earth, orbits close in around the star LHS 1140, a red dwarf star about 40 light years from Earth. It's in the "Goldilocks region", an orbit where it's not too hot and not too cold, so liquid water can exist on its surface. It was spotte..>> view originalTrillions of Plastic Bits, Swept Up by Current, Are Littering Arctic Waters
The scientists sampled floating plastic debris from 42 sites in the Arctic Ocean aboard Tara, a research vessel that completed a trip around the North Pole from June to October 2013, with data from two additional sites from a previous trip. They scooped up plastic debris and determined the concentration of particles by dividing the dry weight of the plastic collected, excluding microfibers, by the area surveyed.Almost all of the plastic, measured by weight, was in fragments, mostly ranging from..>> view originalScientists have discovered vast systems of flowing water in Antarctica. And that worries them.

(Wong Sang Lee/Korea Polar Research Institute) The surface of the remote Antarctic ice sheet may be a far more dynamic place than scientists imagined, new research suggests. Decades of satellite imagery and aerial photography have revealed an extensive network of lakes and rivers transporting liquid meltwater across the continent’s ice shelves — nearly 700 systems of connected pools and streams in total. “A handful of previous studies have ..>> view originalInside NASA's Plan to Protect the Planet from a Massive Asteroid
When a 65-foot-wide meteor exploded in the sky on Feb. 15, 2013 with the power of 20 atomic bombs, Vladimir Petrov was 20 miles directly below it, standing on a snowy street in Korkino, Russia, by the coal mine where he worked. It was 9:20am on a Friday and most of the town was just waking up or heading to work. It was around 0°F (-18°C), frigid but not unusual for February in the small town between the Ural Mountains and Siberia. Petrov felt a sudden burst of heat, and as he’d describe to scie..>> view originalPhotos of close asteroid 2014 JO25

BUFFALO, N.Y. (WKBW) - Need to make a wish? You may just have that opportunity to do so, as the Lyrid meteor shower is set to peak this weekend. No, it's not as spectacular as the Perseid meteor shower in August. Only 20 meteors per hour are expected to grace the skies. That's about one meteor every three minutes. And the timing couldn't be more perfect, as the moon will be in a waning crescent phase. The moon will rise in the pre-dawn hours so it won't have much impact on viewing.If you were h..>> view originalPresident Trump to Call NASA Astronaut Peggy Whitson in Space Monday
