#3IATLAS update: we've just pinpointed the comet's path with 10 times more accuracy, using data from our #ExoMars Trace Gas Orbiter spacecraft. 😎🧪🔭

1/ Milestone achieved by the VLTI upgrade GRAVITY+: a laser has been installed at each of the previously unequipped VLT Unit Telescopes.

This will dramatically enhance the VLTI observing power.

Four astronomical domes stand in a desert landscape, each launching a bright orange laser into the sky. A nearly full moon glows on the left of the image. The text “What are these lasers for?” is visible on the image.

Introducing...your sneak peek at the cosmos captured by NSF–DOE Vera C. Rubin Observatory!

Can you guess these regions of sky?

This is just a small peek...join us at 11am US EDT for your full First Look at how Rubin will #CaptureTheCosmos! 🔭🧪

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black. A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars. A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

Astronomers have created a galactic masterpiece!

Using our VLT, they observed the Sculptor Galaxy in thousands of colours simultaneously 🌈

The more shades of colour there are in an image of a galaxy, the more we can learn about its inner workings.

A spiral galaxy, showing a thousand different colours that indicate the regions of different stars, gas and dust. The centre of the galaxy has more golden and orange light, while the outer edges fade into a deep blue that further fades into the black of the universe. Speckled across the galaxy are portions of bright pink light, along with patches of brown and black.
