OTD…April 24 and the birth of Hubble

#OTD in 1995…Columbia launched on a microgravity science Spacelab flight

The Hubble Space Telescope turned toward Jupiter last month, capturing colorful views of the giant planet and its icy moon Europa more than 400 million miles from Earth.

Scientists announced Thursday that measurements from NASA’s Cassini spacecraft detected hydrogen gas, a key energy source for microbial life, in a plume gushing from a vast liquid water ocean buried beneath the icy shell of Saturn’s moon Enceladus.
