NASA’s Kepler space telescope was responsible for the discovery of over 2,700 confirmed extrasolar planets, more than half of the total number of exoplanets known today. These discoveries took place during both Kepler’s primary mission, when it spent 4 years staring at the same part of the sky, and its extended K2 mission, when a mechanical failure forced it to observe different parts of the sky along the ecliptic. At the very end of the mission,...

Radio SETI has focused on the discovery of narrowband signals and artificially dispersed broadband pulses from extraterrestrial worlds; in contrast to these technosignature morphologies, periodic spectral signals offer an energetically efficient means of transmission across vast interstellar distances; a rotating beacon at the Milky Way’s center is, in particular, advantageously placed for galaxy-wide communications.

This Hubble image shows NGC 298, a spiral galaxy some 89 million light-years away in the constellation of Cetus. The color image is a composite of separate exposures acquired by Hubble’s Advanced Camera for Surveys in visible and near-infrared light. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / C. Kilpatrick.
