Astronauts cannot use conventional pens and pencils in outerspace. Here's why:
Clouds weigh several tons but stay airy by distributing their weight over a large area.
Saturn's rings are made of the remnants of former moons that were destroyed in a collision.
Our moon stabilizes Earth's axis and makes for habitable conditions; but, scientists discover, life is still possible without moonlit nights.
Extrasolar planets form along misaligned orbits.
The Appalachian Mountain range has a strange bend in it caused by the gravitational pull of certain underground rocks.
Despite weighing tons, clouds seem to free-float in the air. How do the billowy marvels stay up in the sky?
Research has shown that people snore less in space. Could this have any ramifications has for us here on Earth?
Rip tides have taken on mythical proportions as killer waves.
If the earth keeps accumulating mass, does that mean that the Earth's gravitational pull has been increasing?
