Life on earth: Why we may have the moon's now defunct magnetic field to thank for it

The habitability of a planet depends on many factors. One is the existence of a strong and long-lived magnetic field. These fields are generated thousands of kilometers below the planet's surface in its liquid core and extend ...

The colorful walls of an exposed impact crater on Mars

Impact craters have been called the "poor geologists' drill," since they allow scientists to look beneath to the subsurface of a planet without actually digging down. It's estimated that Mars has over 600,000 craters, so ...

Research team observes hot dust rings around stars in a new wavelength range

The phenomenon of hot dust rings—an accumulation of submicrometer-sized particles in the immediate vicinity of stars—was first discovered outside our solar system in 2006. They form so close to stars that they can reach ...
