Perfecting the technology needed for ‘starshades’

14 June 2019 Astronomy Now

Engineers are studying plans for a future “starshade” that would block out a star’s light, allowing a distant telescope to directly image smaller exoplanets.

New study suggests tighter restrictions on exoplanet habitability

11 June 2019 Astronomy Now

New research indicates a star’s habitable zone may be narrower than previously believed, making it tougher for ET to evolve and thrive.

NASA to shut down Spitzer Space Telescope early next year

1 June 2019 Stephen Clark

After a search for an outside funding source turned up empty, NASA plans to end observations with the Spitzer Space Telescope in January to conclude a 16-year mission that discovered exoplanets, studied galaxies in the ancient universe, and peered at planets and asteroids in our own Solar System.
