The Veil Nebula
With giant storms, powerful winds, auroras, and extreme temperature and pressure conditions, Jupiter has a lot going on. Now, NASA’s James Webb Space Telescope has captured new images of the planet. Webb’s Jupiter observations will give scientists even more clues to Jupiter’s inner life.

At the heart of the Rosetta nebula is an open cluster of stars, which is NGC 2244. The entire structure sits at the end of a giant molecular cloud, and you can easily spot the tell tale columns and protostars at the head showing active star formation on-going.
The bottom image is from Chandra, which gives the purple/pink colours for X-Ray sources, used particularly in spotting black hole accretion disks, pulsars and supernova remnants, we can see it's a lively place !
The entire structure is in the constellation of Monoceros at around 5,200 light years from Earth.
Galaxies can merge, collide, or brush past one another — each of which has a significant impact on their shapes and structures. As common as these interactions are thought to be in the Universe, it is rare to capture an image of two galaxies interacting in such a visibly dynamic way. This image, from the NASA/ESA Hubble Space Telescope, feels incredibly three-dimensional for a piece of deep-space imagery.
The subject of this image is named Arp 282, an interacting galaxy pair that is composed of the Seyfert galaxy NGC 169 (bottom) and the galaxy IC 1559 (top).

Explanation: Peering from the shadows, the Saturn-facing hemisphere of tantalizing inner moon Enceladus poses in this Cassini spacecraft image. North is up in the dramatic scene captured during November 2016 as Cassini’s camera was pointed in a nearly sunward direction about 130,000 kilometers from the moon’s bright crescent. In fact, the distant world reflects over 90 percent of the sunlight it receives, giving its surface about the same reflectivity as fresh snow. A mere 500 kilometers in diameter, Enceladus is a surprisingly active moon. Data and images collected during Cassini’s flybys have revealed water vapor and ice grains spewing from south polar geysers and evidence of an ocean of liquid water hidden beneath the moon’s icy crust.

Explanation: There goes another one! Volcanoes on Jupiter’s moon Io keep erupting. To investigate, NASA’s robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is about the size of Earth’s moon, but because of gravitational flexing by Jupiter and other moons, Io’s interior gets heated and its surface has become covered with volcanoes. The featured image is from last week’s flyby, passing within 12,000 kilometers above the dangerously active world. The surface of Io is covered with sulfur and frozen sulfur dioxide, making it appear yellow, orange and brown. As hoped, Juno flew by just as a volcano was erupting – with its faint plume visible near the top of the featured image. Studying Io’s volcanoes and plumes helps humanity better understand how Jupiter’s complex system of moons, rings, and auroras interact. Juno is scheduled to make two flybys of Io during the coming months that are almost 10 times closer: one in December and another in February 2024.
