Spitzer Space Telescope observations have revealed a small sample of oxygen-rich, asymptotic giant branch stars in the Large Magellanic Cloud that are surrounded by dust primarily composed of solid iron.

Two filament channels with different chiralities met at the solar equator in April 2016 to form a giant dark channel; magnetic flux emergence and cancellation at their junction may have ultimately broken the channel.

Tides raised on a star by a small orbiting body can be used for planet detection. These tides show distinctly different signatures when the body is on an eccentric orbit as opposed to a circular one.

First results from the CHinese Exoplanet Searching Program from Antarctica (CHESPA) reveal 222 objects with plausible transit signals, 116 of which are plausible transiting exoplanet candidates.

A search for high-energy neutrinos associated with detections from Advanced LIGO’s first observing run yielded no significant coincident candidates, allowing constraints to be placed on the rate density of astrophysical sources.

ALMA-discovered molecular gas streams orbiting around an invisible massive object in the central region of our galaxy provide new circumstantial evidence for a wandering intermediate-mass black hole in the galactic center.
