    It may have been imaged many times before, but Webb has revealed new details of this tumultuous galaxy: the scars of a collision with another galaxy; new stars being born while old stars shed dust back into space; and a curious S-shaped feature. 2/3 Read more:

    3. The correct answer is c) The ribbon wave. This is thought to be influenced by otherwise undetectable atmospheric waves. Read more: esawebb.org/news/weic2606/ 📷 @NASA , @esa , @csa_asc , STScI; Image Processing: J. DePasquale (STScI)

    🆕 A turbulent galaxy and its stars, revealed by Webb to mark its fourth science anniversary 🎉 Centaurus A lies 11 million light-years from Earth. Unlike most other ‘nearby’ galaxies, it is very active, making it perfect for understanding how galaxies and black holes grow and
    A horizontal image of the galaxy Centaurus A stretches across a black background filled with thousands of tiny purple, pink, and white points of light. The galaxy is brightest at its centre, where a brilliant white and pale pink glow radiates outward. Eight diffraction spikes extend from the central glow. Delicate loops and wispy ribbons of pink and lavender arc above and below the centre of the image in the shape of an ‘S’. A band of gray and white dust in the shape of a parallelogram cuts across the middle of the galaxy. Mottled patches and bright knots are scattered throughout the dusty band. The galaxy’s outer edges fade into soft, cloud-like plumes with feathery textures that stretch toward the left and right sides of the image. Against the surrounding darkness, a few bright foreground stars shine with Webb’s distinctive diffraction spikes, while countless fainter stars create a speckled backdrop.

    A diagonal image of the galaxy Centaurus A stretches from the upper left to the lower right against a deep black background filled with countless tiny orange, blue, and white points of light. The galaxy is brightest at its centre with a white glowing core. A broad band of golden-orange dust cuts across the middle of the galaxy, forming a distinctive parallelogram shape. The dust in this feature is richly textured, with mottled patches, bright knots, and intricate filaments throughout. Just above the centre, delicate peach-coloured ribbons trace an S-shaped structure. Rather than appearing smooth, the galaxy has a finely speckled texture created by millions of individually resolved stars, which fill the central regions and extend into the surrounding glow. The galaxy’s outer edges dissolve into diffuse, cloud-like plumes with feathery textures that stretch beyond the dust lane. Against the surrounding darkness, several bright foreground stars display Webb’s distinctive diffraction spike

    🆕 Our ESA/Webb Picture of the Month features a cosmic construction project 👷‍♂️🏗️ This is the galaxy cluster MACS J0553.4-3342, which is seen in this #NIRCam image as it was 4.4 billion years in the past. The cluster is actually composed of two sub-clusters which are in the
    A galaxy cluster in deep space. It is filled with elliptical galaxies: small, bright white glowing ovals. The two largest elliptical galaxies, left and right of center, are bright cores that radiate light. Unrelated, distant galaxies are scattered around as red smudges and dots.Many of these are stretched out into red arcs and lines by the galaxy cluster’s strong gravity, creating multiple images in places. Numerous spiral galaxies and bright stars appear in the foreground.

    Even mid-way through construction, the titanic clumps of matter in MACS J0553.4-3342 have built a device that is useful for us here on Earth: a gravitational lens. The extreme gravity of the cluster curves light, similar to a glass lens 🔍 2/3

    A gravitational lens is a useful device for astronomers, making distant background galaxies and even individual stars visible. Some of the galaxies seen in this image are from less than a billion years after the Big Bang! Read more: esawebb.org/images/potm260… #WebbSeesFarther 📷

    🆕 The #NIRCam on Webb has captured the protostars of the FS Tau system. These are just 1 to 3 million years old – young by cosmic standards! 👶⭐ 1/2
    FS Tau, a star-forming nebula. Clouds of transparent blue and purple gas and dust extend from slightly left of centre to the right side of the frame, from 2 o’clock to 5 o’clock. Several yellow and white protostars, some showing Webb’s eight-pronged diffraction pattern are dispersed throughout the clouds. Orange wisps and filaments of gas extend from one of the protostars at the centre toward the top left and bottom right corners of the frame. There are numerous, distant yellow and white galaxies strewn about the black background of space.

    A pair known as FS Tau A is responsible for the large diffraction pattern left of centre, while the red and orange outflows seen amidst the dust are thought to be caused by FS Tau B, the orange protostar just right of centre.  Read more: esawebb.org/images/FS-Tau/ #WebbSeesFarther
