Exploding “heat bombs” might explain why the sun’s upper atmosphere, or corona, sizzles at millions of degrees – hundreds of times hotter than at the surface.
Asteroid 2015 TC25 is small enough to be straddled by a person, reminiscent of the iconic bomb-riding scene in the movie Dr. Strangelove. It swept between us and the moon a year ago.
Due to shifting weather patterns, the northeastern coast of the United Sates could see more frequent and more powerful hurricanes in the future, says new research.
Earth without its moon would be a very different world indeed. No eclipses. Smaller tides. But the biggest change would be in the length of Earth’s day.
NOAA’s outlook for this winter predicts a warmer, drier South, and cooler, wetter North. Drought is expected to persist in California and expand in the Southeast.
A camera on board ESA’s ExoMars mission has returned its first images from orbit. It was meant to be a test, but the images are spectacular.
These strange galaxies have 1,000 times fewer stars than the Milky Way, yet occupy a large space. Astronomers used an advanced computer simulation to show that supernova explosions helped create them.
Near the Arctic Circle, in northern Alaska, is where forests give way to tundra. Researchers are looking at how the warming climate might affect the ecology of this northern boundary.
On November 30, the Cassini spacecraft will begin a series of 20 orbits that fly high above and below Saturn’s poles, plunging just past the outer edge of the main rings.
Photog Adventures sent its GoPros to space, captured some stunning views, and then lost the cameras for 15 days. Follow the adventure in this video.
Researchers have now mapped a preserved underwater site off the coast of Sweden. They think it was a lagoon where Mesolithic humans lived during parts of the year.
Scientists have discovered a Great Valley on Mercury, hundreds of miles long and sunken by as much as 2 miles (3 km) below the surrounding terrain.
Time-lapse by the Cassini spacecraft shows methane clouds moving across northern regions of Saturn’s largest moon, Titan, on October 29 and 30.
The Arctic’s multi-year sea ice – ice that survives the summer melt – is weaker and there’s less of it. Satellite images show the difference between 1984 and now.
On Sunday, October 30, NASA’s Solar Dynamics Observatory caught the moon passing in front of the sun.
These stars produce X-rays at 100 times our sun’s peak levels. They spin so fast they’ve been squashed into pumpkin-like shapes.
Thinking of the ant colony as a superorganism, entomologist Patricia Pietrantonio is searching for the master regulator genes that may help control them.
Remember when they said it would take more than a year for New Horizons to send its data back from Pluto? Now, say scientists, “We have our pot of gold.”
Observations begin tonight with the Green Bank radio telescope. Astronomers are seeking evidence of an extraterrestrial civilization.
Learning to pull strings for food is often used to test the intelligence of apes and birds. Turns out, bees can learn it too, and pass the skill on to other bees.
