Hubble spies a rebel

Most galaxies possess a majestic spiral or elliptical structure. About a quarter of galaxies, though, defy such conventional, rounded aesthetics, instead sporting a messy, indefinable shape. Known as irregular galaxies, this ...

Technique may reveal the age of moon rocks during spaceflight

Researchers are developing instruments and methods for measuring the ages of rocks encountered during space missions to the Moon or other planets. Many of the techniques used to date rocks on Earth are not practical in spaceflight, ...

Weighing the Antarctic ice sheet

One of the last big unknowns in the global climate equation is Antarctica. How stable is the Antarctic ice sheet? More than a mile thick, on average, it locks up 70 percent of the Earth's fresh water.
