A newly discovered extremely metal-poor RR Lyrae star — a type of low-mass pulsating variable star — may facilitate future investigations of early star formation in the inner regions of the Milky Way.

Deep imaging finds no evidence of planets around the white dwarf Sirius B, but the search demonstrates the value of using this technique to characterize potential planetary systems around white dwarfs.

The first systematic search for protostar outbursts in one of the most active star-forming regions in the Milky Way finds that protostars undergo outbursts for at least 9 years every 438 years.

Observations in the direction of O-type star Zeta Ophiuchus reveal three different dust populations at varying distances, one of which is highly polarized and may be associated with prominent stripes seen in the infrared.

A recent impact event on a main-belt asteroid provides the first confirmation of the expected weathering trends of rocky asteroids and suggests that outer solar system objects could be hiding in the asteroid belt.

A team reports on an initial sample of 118 old, low-mass stars observed by the Transiting Exoplanet Survey Satellite and explore the pulsation modes seen in these abundant variable stars.
