Rodents help NASA take the next step to Mars

NASA's future deep space exploration – including to Mars – is an unprecedented venture in spaceflight, requiring us to tackle challenges we've never faced before. For instance, we know the human body changes significantly while in space, and we'll need to find ways to address those effects. Show More Summary

Image: Highlighting Titan's hazes

NASA's Cassini spacecraft looks toward the night side of Saturn's moon Titan in a view that highlights the extended, hazy nature of the moon's atmosphere. During its long mission at Saturn, Cassini has frequently observed Titan at viewing angles like this, where the atmosphere is backlit by the Sun, in order to make visible the structure of the hazes.

Stardust hitches a ride on meteorites more often than previously thought

Even tiny dust particles have stories to tell ? especially when they come from outer space. Meteorites contain tiny amounts of what is popularly known as stardust, matter originating from dying stars. Such stardust is part of the raw...Show More Summary

Lungs in space: research project could lead to new lung therapeutics

Space travel can cause a lot of stress on the human body as the change in gravity, radiation and other factors creates a hostile environment. While much is known about how different parts of the body react in space, how lungs are affected...Show More Summary

Scientists to Take Flight for Longer Views of the Eclipse

Specialized jets will be used to grab data about the sun that cannot be collected from the ground during the Great American Eclipse.

The Illuminating Power of Eclipses

With the sun obscured, eclipses can be revelatory: Starting at least over 2,000 years ago, they have been fodder for significant discoveries.

Out There: During an Eclipse, Darkness Falls and Wonder Rises

A total solar eclipse brings tears, screams, even reverence to those in its path.

Observations of a supernova colliding with a nearby companion star take astrophysicists by surprise

In the 2009 film "Star Trek," a supernova hurtles through space and obliterates a planet unfortunate enough to be in its path. Fiction, of course, but it turns out the notion is not so farfetched.

New 3-D simulations show how galactic centers cool their jets

Some of the most extreme outbursts observed in the universe are the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light. These narrow jets, which typically form in opposing pairs areShow More Summary
