The new CERN Courier looks ahead, to the future of particle physics - and back to the outstanding year of 1964. The story of quarkonia spans all six decades, and its final chapter is now being written. Plus: data preservation, X17, dark energy and more.

Spectacular: Star cluster NGC 1755 resembles a pinch of salt strewn on a jet-black tablecloth in this image. It's 120 light-years from side to side

Despite this impressive breadth, NGC 1755 is in the smaller class of star clusters

if you zoom into this image from euclid, you can see a beautiful einstein ring at the center of the galaxy ngc 6505 🌌
The large, hazy oval of elliptical galaxy NGC 6505 illuminates the center of this image from the European Space Agency's Euclid mission. At the heart of the galaxy is a small bright spot surrounded by a thin white circle, which is a magnified view of a much more distant galaxy. The view is also filled with countless colorful stars and galaxies of various sizes and shapes amidst the blackness of space. Thin spikes of light extend from the brightest stars due to the observatory’s optics. The image is watermarked “Credit: ESA/Euclid/Euclid Consortium/NASA, image processing by J.-C. Cuillandre, T. Li” and “CC BY-SA 3.0 IGO.” A close-up view of the center of the NGC 6505 galaxy, with the bright Einstein ring aligned with it, captured by ESA’s Euclid space telescope.

🔭 The Universe is a dusty place.

This NASA/ESA Hubble Space Telescope picture shows swirling clouds of gas and dust near the Tarantula Nebula, the most productive star-forming region in the nearby Universe, home to the most massive stars known.
A portion of a nebula, made of variously-coloured layers of dust clouds. One upper layer is dark reddish dust which is dense and obscures light, in places so dense that it appears black. A middle layer is pale clouds that are thick like curling wisps of smoke. They form a broad bow across the centre of the image. Many small, bright stars lie throughout the nebula, coloured blue, purple or red depending on depth.

these webb/hubble images are truly incredible. the fact that we can see the universe in different wavelengths of light and spot so many unseen details is mind-blowing 🌌
Two observations of a portion of the galaxy NGC 628 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is roughly centered and the galaxy’s arms appear to rotate counterclockwise. The spiraling filamentary structure looks somewhat like a cross section of a nautilus shell. In Webb’s image, the spiny spiral arms are composed of many filaments in shades of orange, with prominent dark gray or black “bubbles,” and there is a blue haze near the core. In Hubble’s image, the spiral arms are a mix of bright blue star clusters, pink star forming areas and dark brown dust lanes, and the core is a pale yellow. Two observations of the galaxy NGC 1300 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered, connected to a prominent diagonal bar structure. The galaxy’s two distinct spiral arms begin at the end of the bar and rotate counterclockwise. Together, the arm and bars form a backward S shape. In Webb’s image, the bar and spiral arms are composed of many filaments in shades of orange, and are anchored by its central region, which is circular and light yellow. In Hubble’s image, the spiral arms are a mix of bright blue star cluster and dark brown dust lanes, and the bar and core are a pale yellow. Two observations of the galaxy NGC 1512 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered and circular, with two prominent dust lanes crossing the large diagonal bar structure appearing toward the top left and bottom right. The central bar is blue at top, looking like a gap until a closer examination shows it feeds a larger, oval shape that looks braided with many spiral arms. In Webb’s image, the spiral arms are composed of many filaments in shades of orange. In Hubble’s image the bar is a light pinkish-brown and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes. Two observations of the galaxy NGC 3351 are split diagonally, with Hubble’s observations at top left and Webb’s at bottom right. The galaxy’s core is centered and the galaxy’s arms rotate clockwise and form a distinct outer ring. In Hubble’s image, the galaxy’s roughly horizontal bar structure is a pale yellow and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes that form half of the large circular ring. In Webb’s image, the spiral arms form the other half of the large ring, which is made of many filaments in shades of orange. They are anchored by its central region, a hazy blue bar, connected to the central core. The core has a small orange oval around a more circular light yellow oval, with a blue dot at its center.

🔭 Comet G3 ATLAS: a Tail and a Telescope

Image Credit & Copyright: Yuri Beletsky (Carnegie Las Campanas Observatory, TWAN)

apod.nasa.gov/apod/ap25012...
Comet C/2024 G3 ATLAS has made a dramatic appearance in planet Earth's skies. A visitor from the distant Oort Cloud, the comet reached its perihelion on January 13. On January 19, the bright comet was captured here from ESO Paranal Observatory in the Atacama desert in Chile. Sporting spectacular sweeping dust tails, this comet ATLAS is setting in the southern hemisphere twilight and was clearly visible to the unaided eye. In the foreground is the closed shell of one of the observatory's famous auxiliary telescopes. Still wowing southern hemisphere observers, the comet's bright coma has become diffuse, its icy nucleus apparently disintegrating following its close approach to the Sun.

🚀 One year ago today, ESA project astronaut Marcus Wandt from Sweden became the first of a new generation of ESA astronauts to fly to the International Space Station with #AxiomSpace. He pioneered fast-track, short-duration missions for more science, tech and education. Do you know who's next? 😉

The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion’s Belt, and is part of the much larger Orion Molecular Cloud Complex.

Ever looked up and spotted a twinkling gem? That’s Capella, just 42 light-years away, made up of not one, but two giant stars locked in an eternal dance! It’s one of the brightest stars in our night sky! #astronomy @kat-astro-bot.bsky.social

Do you think you're sitting still right now?

- You're on a planet that orbitis a star at 30km/s

- That star is orbiting the center of a galaxy at 230km/s

- That galaxy is moving trough the universe at 600km/s.

Since you started reading this, you have traveled about 3000km.
