Astronomy & Space

Astronomy may well be the oldest science of all, seeking answers to questions such as: "Where did it all come from?" and "Are we alone?" But, today's astronomers are focusing on phenomena our forbearers never imagined—planets orbiting other stars, for example; black holes the size of our solar system; galaxies being driven apart by invisible "dark energy"; ripples in the fabric of space and time; and of course the big bang, where time itself began.

Storms In Space

Storms In Space

We depend on the Sun for heat and light, but there's a lot more going on than meets the eye," says NCAR solar physicist Scott McIntosh. On a whirlwind tour of the Sun's magnetic forces, MacIntosh describes the impact solar storms can have on Earth's environment and explains how scientists study this powerhouse of mass and energy.

Science Behind The News: Impacts On Jupiter

Science Behind The News: Impacts On Jupiter

The impact of comets on the surface of Jupiter are a fairly common experience. At the University of Central Florida, astronomers Joseph Harrington and Csaba Palotai are leading a project that studies precisely how these impacts happen, and also provides valuable information about what might happen if such a comet struck Earth.

We Are All Stardust

We Are All Stardust

When a meteor hits the earth, there is the possibility that it brings something very rare along with it: cosmic stardust older than our Solar System.

Mapping The Infant Universe

Mapping The Infant Universe

Dr. Charles Bennnett and his 26-member team were awarded the Gruber Foundation's 2012 Cosmology Prize for their transformative study of an ancient light dating back to the infant universe.

Most Distant Quasar Found

Most Distant Quasar Found

This ESOcast is about the discovery of the most distant quasar found to date. This brilliant beacon is powered by a black hole with a mass two billion times that of the Sun. It is by far the brightest object yet discovered in the early Universe.
