When Hubble first observed the atmospheric conditions of an extrasolar planet in 2000, it opened up that entire field of study. Now, Hubble has conducted the first preliminary study of the atmospheres of Earth-sized, relatively nearby worlds and found “indications that increase the chances of habitability on two exoplanets,” say the researchers. The planets, TRAPPIST-1b […]
Five time space shuttle astronaut and current NASA science chief John Grunsfeld – best known as the ‘Hubble Hugger’ for three critical and dramatic servicing and upgrade missions to the iconic Hubble Space Telescope – his decided to retire from the space agency he faithfully served since being selected as an astronaut in 1992.

People often criticize the amount of money spent on space exploration. Sometimes it’s well-meaning friends and family who say that that money is wasted, and would be better spent on solving problems here on Earth. In fact, that’s a whole cultural meme. You see it played out over and over in the comments section whenever […]
Jupiter global map created from still images from the Hubble Space Telescope It’s been widely reported, including at Universe Today, that the apple of Jupiter’s eye, the iconic Great Red Spot (GRS), has been shrinking for decades. Even the rate of shrinkage has been steadily increasing. Back in the late 1800s you could squeeze three Earths inside […]
Decades after its momentous launch, the ever popular Hubble Space Telescope merrily continues its trajectory in low-earth orbit, and it still enables cutting-edge science. Astronomers utilized Hubble and its instruments over the years to obtain iconic images of the Crab Nebula, the Sombrero Galaxy, the Ultra Deep Field, and many others that captured the public […]
