Story Archives of 'Space'

American scientists recently crashed a probe into the moon and found lots of frozen water, a discovery that could have major implications for future space exploration. Also, the end is in sight for the shuttle program, and new images from a souped-up Hubble telescope give us the best pictures ever of the birth of a star. We’ll talk about these and other ‘out of this world’ news from space.

Four hundred years ago today, Galileo di Vincenzo Bonaiuti de’ Galilei demonstrated his first telescope to Venetian lawmakers. It was from this and other stronger telescopes that Galileo was able to discover mind-blowing details about our universe. His notion of a heliocentric system would cost him his freedom by the Roman Catholic Church, while his advancements in mathematics, motion and astronomy would earn him titles from the Father of Physics to the Father of Modern Science. We’ll look back at the life, achievements and legacy of Galileo Galilei.

On the 40th anniversary of the moon landing, we look at the feasibility of a human voyage to the Red Planet. A manned Mars mission is a dream of many astro-philes, but such a trip poses huge challenges: the logistics of carrying food, fuel and water, astronaut fatigue and psychological demand, delays in communication, danger and, an $18 billion price tag. We’ll talk about why some say it is important to land humans on Mars, what could be in its way, and how we might get around those challenges.

We’re turning up the volume on outer space.

Gravitational waves from exploding stars and black holes fill the universe with sounds we can’t hear. For the first time, scientists are learning how to tune in - and they’re hoping to uncover mysteries about the origins of the universe.

For more on this, we were joined by Janna Levin. She’s a professor of physics and astronomy at Barnard College of Columbia University. She joined us from Oxford College in England, where she’s on retreat this summer.

Harvard researchers have confirmed the existence of a new supernova.

It’s an unusual discovery for two reasons. One, it might be the weakest supernova ever seen. And two, it was first spotted back in November by a 14-year-old using an ordinary telescope. Caroline Moore lives in Warwick, New York. She took time out to talk to us while studying for her freshman finals.
