As the 2017 North American total solar eclipse comes to an end, the famous "diamond ring" becomes visible. The sun's corona is also visible, with the star Regulus to the left.

A Total Solar Eclipse 100 Years Ago Proved Einstein’s General Relativity

Two teams of astronomers voyaged to Africa and Brazil to observe the most famous eclipse in science

Fifty years ago, the astronauts who crewed the “dress rehearsal” for Apollo 11 paved the way for history to be made just a couple months later

To all the looney lunar landing deniers and conspiracy theorists out there, NASA has just four words to say: "Apollo: Yes, We Did."

A photographic plate of the 1919 total solar eclipse, taken by Andrew Claude de la Cherois Crommelin and Charles Rundle Davidson during an expedition to Sobral, Brazil. The 1919 eclipse was used by Arthur Eddington, who observed it from the island of Principe off the west coast of Africa, to provide the first experimental evidence of Einstein's theory of relativity.

What the Obsolete Art of Mapping the Skies on Glass Plates Can Still Teach Us

The first pictures of the sky were taken on glass photographic plates, and these treasured artifacts can still help scientists make discoveries today

Shortly after the first human space flight, the Soviet Union began planning to send a woman to space.

Jennifer Levasseur from the National Air and Space Museum notes that the museum’s supply of popular astronaut foods is less comprehensive than its collection of rejects. “We only get what they didn’t eat (above: Apollo 17's spiced fruit cereal is now in the collections)."

Rita Rapp Fed America’s Space Travelers

NASA’s food packages now in the collections of the Air and Space Museum tell the story of how a physiologist brought better eating to outer space
