Astrophotographer Adam Block talks about the galaxy known as Messier 87, home of the supermassive black hole photographed by the Event Horizon Telescope.
An artist's impression of the perpetual sunrise that might greet visitors on the surface of planet TRAPPIST-1f. If the planet is tidally locked, the "terminator region" dividing the night side and day side of the planet could be a place where life might take hold, even if the day side is bombarded by energetic protons. In this image, TRAPPIST-1e can be seen as a crescent in the upper left of the image, d is the middle crescent, and c is a bright dot next to the star. Image credit: NASA/JPL-Caltech

Two new studies by UA space scientists may bring into question the habitability of TRAPPIST-1 exoplanets, three of which are in the habitable zone of space.

With the help of two radio telescopes coordinated by the UA, astronomers in the Event Horizon Telescope collaboration have taken the first direct image of a black hole, a prediction of Einstein's General Theory of Relativity.
Bennu's surface is rockier than expected, creating challenges for the team whose mission is to scoop up a sample of pristine material and return it to Earth in 2023. (Image: NASA/Goddard/UA)

Incoming assistant professor Jessica Barnes will have the opportunity to study a previously unopened sample of a moon rock that was collected in the early 1970s during NASA's Apollo 17 mission.
NASA's SPHEREx mission is targeted to launch in 2023. SPHEREx will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy's planetary systems. (Image: California Institute of Technology)
