In an effort to understand how black holes shape the evolution of galaxies, astronomers spent eight months creating a series of time-lapse movies from 400 observations made by NASA’s Hubble Space Telescope. The movies, taken from observations conducted over a 13-year period from 1995-2008, show a 5,000-mile-long jet […]

Kepler Recovery Efforts Conclude, Other Missions Mulled

After several months’ worth of review and testing, the team operating the Kepler Space Telescope has opted to close its efforts to make Kepler fully operational again. This follows the loss of one of the crucial components that controls the alien planet-hunting spacecraft. In an Aug. 15 teleconference, Charles Sobeck, deputy […]
