What Makes Balloons Bang When Popped

What makes it goes bang when popped, the science behind it.

History of Solar System Buried on the Moon

Unlike the Earth's surface, which is being constantly scrubbed dean by erosion and plate tectonics, the face of the moon is ancient and scarred, sporting some of the largest impact craters in the Solar System.

New Type of Cosmic Background

A team of scientists using a sensitive balloon-borne instrument has found an unexplained hiss of relatively low-frequency radio pervading the universe. The discovery represents yet another type of "cosmic background radiation" - distant emission coming from everywhere on the sky - to go along with the backgrounds previously discovered in microwaves, infrared light, X-rays, and gamma rays.

Planets Without Stars, Wanders Galaxy Alone

Astronomers have found a new type of planet drifting by itself through space, unbounded to any star. By scanning the crowded center of our Milky Way Galaxy, the international team discovered up to 10 Jupiter sized "orphan planets; about 10,000 to 20,000 light-years from Earth. Details appeared in a May 19 study in Nature.
