"Spanish Dancer" Galaxy
Enjoy this new image from JWST's MIRI of spiral galaxy NGC 1566. The colors in this image come from the emission of dust, although hardly any stars are visible. The reddish areas correspond with star formation.

JWST Deep Field
Take a look at the newest deep field image from JWST, taken as part of the JWST Advanced Deep Extragalactic Survey. The blue six-pointed features are stars in the Milky Way, while every other object is a galaxy. In this image, light at 1.15 microns is blue, light at 2.0 microns is green, and at 4.44 microns is red.

Terraced in Utopia
This type of crater formation has been used in Arcadia Planitia to estimate the thickness and radar properties of mantling units, but there don’t seem to be very many here in Utopia Planitia, Mars. Existing images have significant shadows. Stereo will help us to also look at boulders and polygons.
