Several days ago, we brought you a rare Carl Sagan sketch, where the young scientist depicted an imagined history of interstellar space flight.[...]
Galileo Galilei did not invent the telescope. The honor is usually reserved for Hans Libbershey, a Dutch eyeglass maker, who was at least the first person to apply for a patent, in 1608. But Galileo was a very early adopter, and improver, of the instrument.[...]

Carl Sagan had his first religious experience at the age of five. Unsurprisingly, it was rooted in science. Sagan, then living in Brooklyn, had started pestering everyone around him about what stars were, and had grown frustrated by his inability to get a straight answer.
Let’s let NASA paint the picture for you:
In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.
Sean Goebel, a graduate student in astronomy at the University of Hawaii, has made this beautiful and fascinating time-lapse film of the observatories on Mauna Kea shooting laser beams into the night sky over the Big Island of Hawaii.[...]
In the late 1990s, Neil deGrasse Tyson and his colleagues redesigned the Hayden Planetarium and, without much comment, they created a model of the solar system that banished Pluto from the list of planets. During the following year, no one said very much.[...]
For centuries, seafaring explorers and merchants reckoned with the longitude problem. It was relatively easy to figure out a ship’s location on a north-south axis, but nearly impossible to determine how far east or west it was. And the stakes were high.[...]
Science fans this week got their first tantalizing peek at the long-awaited sequel to Carl Sagan’s classic PBS series Cosmos. Astrophysicist Neil deGrasse Tyson, who takes Sagan’s place in the new series, traveled to Comic-Con in San Diego last week for the unveiling of this new trailer.[...]
Earlier this month NASA announced that the Hubble Space Telescope found evidence of a planet forming 7.5 billion miles from its star. This astonishing discovery challenges all of our current theories about how planets develop.
A few days later, Hubble captured images of two galaxies merging.
