NASA’s TESS planet-finding spacecraft completed its primary mission about 3 months ago. TESS’s (Transiting Exoplanet Survey Satellite) job was to search the brightest stars nearest to Earth for transiting exoplanets. It found 74 confirmed exoplanets, with another ~1200 candidates awaiting confirmation.
It surveyed 75% of the sky during its two-year primary mission, and now NASA has released a composite image of the northern sky, made up of more than 200 individual images.

On April 18th, 2018, NASA’s Transitting Exoplanet Survey Satellite (TESS) took to space for the first time. By August, it began capturing the light curves of distant stars for signs of planetary transits, effectively picking up where the Kepler Space Telescope left off. Now, just a few months away from the end of its primary mission, NASA has put a year’s worth of images of the southern sky together to create the beautiful mosaic you see here.

InSight has been on the Martian surface for almost three weeks, prepping itself for all the science it’s going to do. But in the meantime, it’s doing what any self-respecting, modern robotic lander does: Taking pictures of itself. And now NASA has released InSight’s first selfie for all the lander’s adoring fans and Instagram followers.
InSight is on Mars to study the interior of the rocky planet, and provide clues into how rocky planets form, both here in our Solar System, and in distant systems. It’s got a suite of instruments to do that with, including a device that will drill 5m (16 ft.) deep into the planet to measure how heat flows through the core of Mars. But it’s taking a cautious approach to that, using its time wisely to select the perfect spot to deploy its instruments.
In the meantime, holiday snaps!
