Simulations suggest that close transits of TRAPPIST-1 b and e should allow for removal of stellar contamination and determination of TRAPPIST-1 e’s atmosphere, though in practice difficulties remain.

Under simulated Martian conditions, researchers find that the presence of sunlight decreases the maximum slope of granular surfaces from 35 degrees to 10 degrees.

Analysis of a sub-Saturn exoplanet around an F-type star provides clues that the near-polar alignment observed for these planets around cool stars is also present around hotter stars.

Using a novel combination of direct imaging and grism spectroscopy, researchers have resolved and spectroscopically confirmed the two components of a close pair of active galactic nuclei.

The Transiting Exoplanet Survey Satellite (TESS) identified at least 158,000 oscillating red giants, resulting in a nearly order-of-magnitude increase in the number of known stars of this type.

The LIGO collaboration has discovered a remarkable pair of merging black holes; with estimated masses of 137 and 101 solar masses, these black holes appear to lie within or span the black hole mass gap.
