An underwater Stone Age settlement

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.


Great Valley found on Mercury

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.

Watch summer clouds on Titan

Time-lapse by the Cassini spacecraft shows methane clouds moving across northern regions of Saturn’s largest moon, Titan, on October 29­­­­ and 30.

Decline of Arctic’s thickest sea ice

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.


Spacecraft catches partial solar eclipse

On Sunday, October 30, NASA’s Solar Dynamics Observatory caught the moon passing in front of the sun.

This artist's concept illustrates how the most extreme "pumpkin star" found by Kepler and Swift compares with the sun. Both stars are shown to scale. KSw 71 is larger, cooler and redder than the sun and rotates four times faster. Rapid spin causes the star to flatten into a pumpkin shape, which results in brighter poles and a darker equator. Rapid rotation also drives increased levels of stellar activity such as starspots, flares and prominences, producing X-ray emission over 4,000 times more intense than the peak emission from the sun. KSw 71 is thought to have recently formed following the merger of two sun-like stars in a close binary system. Image via NASA's Goddard Space Flight Center/Francis Reddy

Check out fast-spinning ‘pumpkin’ stars

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.


Science fights to control fire ants

Thinking of the ant colony as a superorganism, entomologist Patricia Pietrantonio is searching for the master regulator genes that may help control them.

New Horizons returns last of Pluto data

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.”


Astronomers to observe Tabby’s Star

Observations begin tonight with the Green Bank radio telescope. Astronomers are seeking evidence of an extraterrestrial civilization.

Bees can learn to pull strings for food

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.
