The European spacecraft Rosetta has become the first ever to catch up with a comet. It is a landmark step in a decade-long mission that scientists hope will help unlock some of the secrets of the solar system. Rosetta will accompany comet 67P/Churymov-Gerasimenko on its trip around the sun and land ...

This video was actually 'recorded live' so to speak, under the silver arch! The silence you hear, is the silence of the dark night in a clearing way up high in the Sierra Nevada Mountain range. Quite a profound and moving experience.

Humans have been obsessed with eclipses for centuries. But, what can they actually teach us about our place in the solar system? Total solar eclipses have helped bring about some of the most important astronomic discoveries. Nicolaus Copernicus’ eclipse observations helped him determine that the Ear

The non-profit B612 Foundation aims to build, launch, and operate the first privately funded deep space mission—a space telescope in orbit around the Sun that will map the inner Solar System in search of asteroids that could impact Earth.

Scientists say there's a place in our solar system outside of Earth that has the chemical make-up to potentially support life. Researchers found that Saturn's sixth largest moon -- Enceladus -- has an ocean that contains phosphorus, which is found in human teeth, bones and DNA. CBS News space consu...

Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in fro

When Wylie Overstreet set up his telescope outside on a whim, he had no idea he would inspire awe in hundreds of strangers on the streets of Los Angeles, reminding them of their common humanity.
