One year ago, astronomers announced the discovery that seven roughly Earth-sized worlds orbited around the nearby star TRAPPIST-1. Now a year later, additional data have refined our understanding of these planets.We now know more about the TRAPPIST-1 system than any other solar system other than our own.

May 3rd, 2017 marks the 5,000th day of NASA's Spitzer Space Telescope mission. This video gives us a detailed look at six of these days, showing how an automated observatory like Spitzer, which is effectively an astronomy robot, spends its time. It’s overall mission design allows for an unprecedented degree of efficiency, allowing it to study the full range of astronomical phenomena including nearby objects in the solar system, stars in our galaxy, and galaxies out to the edge of the observable universe.

Hiding behind the constellations Sagittarius and Scorpius is the center of our own Milky Way galaxy, over 25,000 light years away. This patch of sky is mostly dark in visible light, shrouded by dust clouds that lie between us and the Galactic center. But the infrared vision of NASA’s Spitzer Space Telescope sees through the dust showing us this strange and tumultuous region.
