How a year in space changes bodies

Astronauts are spending a year aboard the International Space Station, and researchers are looking at what happens to their bodies at the molecular level.

Venus, Mars, Jupiter and meteor

Alignment of Venus, Mars, Jupiter and a meteor on the ecliptic plane. Not a large meteor but a little gem of color.

Top 10 most dangerous volcanoes

At the number one spot is the Japanese island of Iwo Jima.

This illustration shows the planet HD 189733b is shown here in front of its parent star. A belt of wind around the equator of the planet travels at 5400mph from the heated day side to the night side. The day side of the planet appears blue due to scattering of light from silicate haze in the atmosphere. The night side of the planet glows a deep red due to its high temperature.

Supersonic winds hurtle around exoplanet

The winds move at 2 kilometers per second. That’s about 7 times faster than the speed of sound and 20 times faster than any winds ever recorded on Earth.

A supervolcano is classed as more than 500 cubic kilometers of erupted magma volume.

What triggers supervolcano eruptions?

Supervolcanoes – massive eruptions with potential global consequences – don’t appear to follow the conventional volcano mechanics, say researchers.

As winter sets in at Titan’s south pole, a cloud system called the south polar vortex (small, bright “button”) has been forming, as seen in this 2013 image. Image credit: NASA/JPL-Caltech/Space Science Institute

Cassini spots monstrous ice cloud on Titan

As winter sets in at the south pole of Saturn’s moon Titan, a massive ice cloud has been forming. It’s the “button” in this image from the Cassini spacecraft.

Using New Horizons images of Pluto’s surface to make 3-D topographic maps, scientists discovered that two of Pluto’s mountains, informally named Wright Mons and Piccard Mons, could be ice volcanoes. The color depicts changes in elevation, blue indicating lower terrain and brown showing higher elevation. Green terrains are at intermediate heights. Image credit: NASA/JHUAPL/SwRI

Pluto might have ice volcanoes

Two of Pluto’s mountains could be cryovolcanoes – ice volcanoes – that might have spewed an ammonia-ice slurry in the recent geological past.

This composite of enhanced color images of Pluto (lower right) and Charon (upper left), was taken by NASA’s New Horizons spacecraft as it passed through the Pluto system on July 14, 2015. This image highlights the striking differences between Pluto and Charon. The color and brightness of both Pluto and Charon have been processed identically to allow direct comparison of their surface properties, and to highlight the similarity between Charon’s polar red terrain and Pluto’s equatorial red terrain. Pluto and Charon are shown with approximately correct relative sizes, but their true separation is not to scale. The image combines blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC). Image credit: NASA/JHUAPL/SwRI

Pluto’s moons spinning wildly

“These are four of the strangest moons in the solar system,” said New Horizons mission’s Mark Showalter. “We still don’t know what to make of it.”
