Watch a video replay of NASA’s exoplanet announcement

The centerpiece of the James Webb Space Telescope has arrived at NASA’s Johnson Space Center in Houston for a three-month test to ensure the observatory’s sensors and gold-coated mirrors work in the frigid temperatures of deep space.

NASA’s new planet-hunting TESS observatory completed its first post-launch thruster firing Saturday, setting up for a big boost Wednesday that will send the spacecraft toward the moon for a flyby next month, the next maneuvers in a two-month process to reach the mission’s final science orbit in mid-June.

Processing images from the camera aboard NASA’s Juno spacecraft orbiting Jupiter has turned into a cottage industry of sorts, as rank amateurs, accomplished artists and experienced researchers turn relatively drab “raw” images into shots ranging from whimsical to spectacular and everything in between.
