Moon Io from Spacecraft Juno Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing & Copyright: Ted Stryk & Fernando García Navarro

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.

The Orion You Can Almost See Image Credit & Copyright: Michele Guzzini

Explanation: Do you recognize this constellation? Although it is one of the most recognizable star groupings on the sky, this is a more full Orion than you can see – an Orion only revealed with long exposure digital camera imaging and post- processing. Here the cool red giant Betelgeuse takes on a strong orange tint as the brightest star on the upper left. Orion’s hot blue stars are numerous, with supergiant Rigel balancing Betelgeuse on the lower right, and Bellatrix at the upper right. Lined up in Orion’s belt are three stars all about 1,500 light-years away, born from the constellation’s well-studied interstellar clouds. Just below Orion’s belt is a bright but fuzzy patch that might also look familiar – the stellar nursery known as Orion’s Nebula. Finally, just barely visible to the unaided eye but quite striking here is Barnard’s Loop – a huge gaseous emission nebula surrounding Orion’s Belt and Nebula discovered over 100 years ago by the pioneering Orion photographer E. E. Barnard.

A scattering of red-orange and blue stars fill the frame of the black background in space. Interstellar gas and dust at the center-right of the image is covering the star cluster and altering the view to see more red wavelengths. Credit: NASA, ESA, ESA/Hubble, Roger Cohen (RU)

Pumpkin space latte, anyone? ☕

Hubble captured this festive array of stars, Terzan 12, found in the Milky Way about 15,000 light-years from Earth. The stars in this cluster are bound together by gravity in a sphere-like shape and are shrouded in gas and dust. As the starlight travels through that gas and dust to Earth, blue light scatters, leaving the redder wavelengths to come through.

Messier-20 Is Called The “Trifid Nebula” Because Of The Three Bright Lobes In The Lower Purple-coloured

Messier-20 is called the “Trifid Nebula” because of the three bright lobes in the lower purple-coloured area. This purple region is emitting light, while the upper blue area is just reflecting it.

It is a local star-forming region in our Milky Way galaxy (4,000 light years away). (at Bordeaux, France) https://www.instagram.com/p/B1bxBljC5H9/?igshid=1g0i6zddk37k
