Jupiter and Ring in Infrared from Webb

Why does Jupiter have rings? Jupiter's main ring was discovered in 1979 by NASA's passing Voyager 1 spacecraft, but its origin was then a mystery. Data from NASA's Galileo spacecraft that orbited Jupiter from 1995 to 2003, however, confirmed the hypothesis that this ring was created by meteoroid impacts on small nearby moons. As a small meteoroid strikes tiny Metis, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a Jovian orbit. The featured image of Jupiter in infrared light by the James Webb Space Telescope shows not only Jupiter and its clouds, but this ring as well. Jupiter's Great Red Spot (GRS) -- in comparatively light color on the right, Jupiter's large moon Europa -- in the center of diffraction spikes on the left, and Europa's shadow -- next to the GRS -- are also visible. Several features in the image are not yet well understood, including the seemingly separated cloud layer on Jupiter's right limb. Celestial Surprise: What picture did APOD feature on your birthday?

DSCOVR -- Earth Polychromatic Imaging Camera (EPIC)

What is DSCOVR

DSCOVR (Deep Space Climate Observatory) is an American space weather station that monitors changes in the solar wind, providing space weather alerts and forecasts for geomagnetic storms that could disrupt power grids, satellites, telecommunications, aviation and GPS.

DSCOVR orbits about a million miles from Earth in a unique location called Lagrange point 1, which basically allows it to hover between the Sun and our planet.
The spacecraft’s EPIC camera takes a new picture of Earth every two hours.
The EPIC camera also captures images of solar eclipses and images of the Moon as it passes between DSCOVR and Earth.

Uniquely positioned at the Earth-Sun Lagrange point, EPIC provides full disc imagery of the Earth and captures unique perspectives of certain astronomical events such as lunar transits using a 2048x2048 pixel CCD (Charge Coupled Device) detector coupled to a 30-cm aperture Cassegrain telescope.
