Solar Orbiter tracks the origin of the Sun's mysterious magnetic switchbacks ☀️ Back in 2022, Solar Orbiter spotted a kink in the solar wind’s magnetic field known as a ‘switchback’ and confirmed it to be S-shaped: something scientists had predicted but not seen directly. 🔭 🧪

Mars’s oddest cloud may be even odder than we thought 🤔 Every spring and summer in Mars’s southern hemisphere a spectacular cloud emerges: the Arsia Mons Elongated Cloud, the most visually striking cloud on the Red Planet. 🔭 🧪

Tan-coloured horizontal rectangle showing part of the surface of Mars imaged by an orbiting satellite. On the right is a ring of concentric circles that indicate a volcano. Stretching to the left of the volcano is a long wisp of white cloud, which seems to emanate from the volcano. We also see the shadow of the cloud just above the cloud itself.

A glowing stellar nursery 👶⭐ Webb’s infrared sensitivity has revealed the protostars & stars of NGC 7129, a stellar nursery that lies 3,300 light-years from Earth. In the centre, lies the massive star LkH(alpha) 234, which has carved into its cloudy surroundings 👉 www.esa.int/ESA_Multimed... 🔭 🧪

A young star cluster filled with many stars that display Webb’s unique eight-pronged diffraction pattern. At its center is a yellow star which sports the largest diffraction pattern. To the left of the star, there is a region filled with yellow dust and gas that extends from the star to the left border of the image. This yellow region extends from the bottom, covering about two-thirds of the image. The yellow region has several blue stars of different sizes embedded within. The top third, which lies outside of the yellow region, holds a few bright protostars, within dense gray gas. Those stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust. There are several background galaxies strewn throughout the image. Credit: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI)

Can planets emerge from the deaths of stars? 💀 Astronomers looking through Hubble data from 1999 have identified unusual amounts of niobium in the chemical signatures from a white dwarf. 🔭 🧪

Artist's impression of a gaseous planet in the right foreground, seen mostly in silhouette, orbits a small, white star in the background at left. The star is surrounded by a thin, bright white disk tilted from lower left to upper right. A semi-transparent tail of material comes off the planet toward the upper right. Distant stars dot the black background of space. Credit: NASA, ESA, L. Hustak (STScI)

Ten years ago one daring spacecraft made a final descent 🥹 On 30 September 2016, the Rosetta mission concluded with a controlled impact onto Comet 67P/Churyumov–Gerasimenko, taking one last image. 🔭 🧪

Rosetta's last image of Comet 67P/Churyumov–Gerasimenko: a blurry close-up of a grey surface scattered with boulders and pebbles.

Inspector Smile is ready for science! 🫡 This is Smile’s first ultraviolet view showing an auroral substorm. With the ultraviolet camera now operational, Smile becomes the first spacecraft since 2008 to capture the full ring of northern lights around the north pole in ultraviolet light. 🔭 🧪 ☀️

A galactic house of mirrors 🌌🪞 Webb has captured this spectacular view of the galaxy cluster MACS J0454.1-0300. Its gravity is warping & multiplying the images of background galaxies, which appear like they have stepped into a house of mirrors! Read more 👉 www.esa.int/ESA_Multimed... 🔭 🧪

A massive galaxy cluster, made of many golden elliptical galaxies with the largest, brightest one in the centre. Heavily distorted orange galaxies appear all around the cluster, the largest concentrated in a large arc around the cluster's centre; these are images of very distant galaxies, created by gravitational lensing. A few galaxies are large and bluish-white in colour; bright, nearby stars are the same colour. Credit: ESA/Webb, NASA & CSA, L. Furtak, S. Fujimoto

A successful Earth flyby improves Juice’s course to Jupiter Earlier today, Juice flew just 8640 km above the Indian Ocean and snapped these images with its onboard monitoring cameras. 1️⃣Africa, by Juice monitoring camera 2️⃣Madagascar, by Juice NavCam 3️⃣Moon, by Juice NavCam 🔭 🧪 #planetsci

Mostly black space, most of Earth visible at the top right of the image. Part of a spacecraft visible on the left.Part of the island of Madagascar in black and white.A crescent Moon, with about a quarter of the Moon showing. Many craters are visible.

Earth and Venus may have started out as near twins, but today one is full of life and the other is a scorching greenhouse world 🌋 ESA's Envision launches in 2031 to find out why they turned out so differently. Discover more here 👉 esa.int/envision 🔭

An image of Earth and Venus on a black background, with the Envision spacecraft in the foreground. The left half of Venus shows what it looks like from space, enshrouded in a thick cloud cover (image by NASA's Mariner 10 spacecraft), while the right half shows a map of the surface terrain as reconstructed from radar data recorded by NASA's Magellan mission.
