Deep space travel might increase heart risk for astronauts

A new study suggests traveling beyond Earth’s magnetic shield can actually compromise long-term cardiovascular health. Scientists are starting to learn more about the toll space travel takes on the human body. When, earlier this year, astronaut Scott Kelly returned to Earth after nearly a year in space, his vertebrae had expanded and he’d grown 2 inches. In short, microgravity really screws with you.

Happy birthday, NASA!

On July 29, 1958, President Dwight D. Eisenhower signed the the National Aeronautics and Space Act, in which “Congress hereby declares that it is the policy of the United States that activities in space should be devoted to peaceful purposes for the benefit of all mankind” and established the National Aeronautics and Space Administration to fulfill this policy. Since then, NASA’s space explorations, landing missions, and discoveries have been out of this world!

aw! nasa has a department called “the office of planetary protection” and theyve got a special badge like a police badge but it says “planetary protection”. they clean everything and make sure no earth contaminants get on other planets and that no contaminants from other planets get on earth. they protect “all planets, all the time.” cant wait until we find extraterrestrial life and they become less a nerdy janitorial crew and more like an intergalactic police force.

This lavishly illustrated and somewhat bizarre UFO book is aimed at kids. The text includes a lot of factual astronomy and science and leaves open the question of the reality of UFOs but the illustrations are entertainingly “off the planet”
