The TESS Habitable Zone Stars Catalog is a list of 1,822 bright nearby stars with reliable distances from Gaia DR2, around which NASA’s TESS mission can detect transiting planets that receive Earth-like irradiation.

A comparative study of the 2012 July and 2017 July solar eruptions suggests that superstorms are “perfect storms” in nature, i.e., a combination of circumstances results in an event of an unusual magnitude.

The Large Synoptic Survey Telescope will begin regular survey operations by 2022 and, over the nominal 10 years of observations, will produce 32 trillion observations of 20 billion galaxies and a similar number of stars.

A radial-velocity study is conducted for three systems (Kepler-25, -65, and -68) with similar architectures: a giant-planet companion exterior to a compact, multiply transiting system of sub-Neptune planets.

Data analysis on penumbral geyser-like flaring structures in the Sun’s corona show that they produce recurring jets and can be long-lived, quasi-stable, and act as coronal sources for Type-III radio bursts.

Dust modeling suggests that the narrow circumsolar ring of dust observed by the Helios and STEREO spacecrafts to be associated with Venus’s orbit is most likely produced by a population of Venus co-orbital asteroids.
