The astrophysicist says that participating in a "great unfolding of a cosmic story" should make us feel large, not small. This spring, Tyson hosts a TV series called Cosmos: A Space-Time Odyssey.
Chinese officials recently announced the rover was experiencing mechanical difficulties, and now observers believe its done for. But the thirst for more moon missions may be spreading in China.
Some of the earliest science fiction imagined voyages to Mars. We now have the space-faring technology to make reaching the Red Planet possible. It would involve massive resources and many potential dangers, but some believe the rewards would be massive.
Each winter, a team of scientists sets out on a search for those rare shooting stars that make it to the ground instead of burning up in the sky. There aren't many better places to look for these space rocks than Antarctica, often in areas where no human has set foot before.
Saturday morning, astronauts on the International Space Station carried out the first of three urgent spacewalks to repair a cooling line. They finished the work early, but there's still more to be done.
On Dec. 19, 1958, a pre-recorded message from President Dwight D. Eisenhower was sent out from a satellite via short wave. It offered hopes for peace on earth and goodwill toward men everywhere. Of course, it also let the Soviets know the U.S. was catching up in the space race.
NASA astronauts will be heading out to conduct critical repairs on the International Space Station early Saturday morning. The 6 1/2-hour spacewalk, the first in a series, will replace a faulty piece of cooling equipment.
By putting light sensors inside a giant ice cube that's a mile beneath the South Pole, scientists detected 28 neutrinos from beyond the solar system. It's just a start – but researchers hope the work could eventually yield a way to see through debris clouds to the core of exploding stars.
