The image columns show the change of Uranus for the four years that STIS observed Uranus across a 20-year period. Over that span of time, the researchers watched the seasons of Uranus as the south polar region darkened going into winter shadow while the north polar region brightened as northern summer approaches.

20-Year Hubble Study of Uranus Yields New Atmospheric Insights

The clearest look in the infrared yet at the iconic multi-planet system HR 8799. Colors are applied to filters from Webb’s NIRCam (Near-Infrared Camera). A star symbol marks the location of the host star HR 8799, whose light has been blocked by the coronagraph. In this image, the color blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to the 4.6 micron light

Temperamental stars are distorting our view of distant planets

An artistic impression of Trappist-1 b shortly before it passes behind the cool, red dwarf star, Trappist-1. Such stars are known for their activity with large starspots and eruptions. Trappist-1 b may experience intense volcanism.

NASA Teams Up for a Double Take on Uranus: Hubble and New Horizons Get Up Close and Personal

Physicists at The University of Texas at Arlington have published a study of F-type star systems, in which they explored systems where the planets spend at least part of their orbits in the stellar habitable zones.

Iron Winds Sweep Across Ultra-Hot Exoplanet WASP-76 b

$Magma ocean planets that contain water – like the earthlike exoplanet GJ 1214 b in this artist’s concept – will only host a tiny fraction of this water on their surface. The majority of it is stored deep in their interiors.$
