IBEX observations of the heliotail reveal “lobes,” distinct localized emission features that provide information on the structure and geometry of the inner heliosheath flow around the Sun.

A dimensionless index is developed to quantify the degree of cloudiness of the atmospheres of transiting exoplanets. A tentative correlation is found between more-irradiated atmospheres and fewer clouds.

Magnetic imaging data from SDO is used to study the rotation of sunspots from two different solar cycles. The rotational direction and magnetic polarity of the sunspots switch between the two cycles.

A friends-of-friends algorithm is used to construct a catalog of 1588 compact groups of 3 or more galaxies at redshift 0.01 < z < 0.19. These can be used to study galaxy–galaxy interactions in dense systems.

The Sun may be in a transitional evolutionary phase, suggest data from rotation–age stellar relations. These data indicate that beyond middle-age, magnetic braking efficiency in stars is dramatically reduced.

An experimental adaptive-optics (AO) instrument at the ESO Very Large Telescope is used to image five luminous quasars at z~2 and one at z~4 in near-IR, demonstrating the capabilities of this AO system.
