This decimeter-sized (2 kg) rocky meteoroid entered the atmosphere of our planet about 100 km north of Edmonton, Alberta, Canada at 13:23:17 UTC on February 22, 2021. The object came from the Oort cloud, a reservoir of icy planetesimals and the source of long-period comets.

This Webb image shows NGC 7469, a barred spiral galaxy some 206 million light-years away in the constellation of Pegasus. The galaxy has blue-purple hues with orange-red regions filled with stars. NGC 7469’s companion galaxy, IC 5283, is partly visible in the lower left portion of this image. Also visible is large diffraction spike, which appears as a star pattern over the central region of the galaxy. Lots of stars and galaxies fill the background scene.
