  • ?? This collage of images from the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope provides a detailed view into the Flame Nebula ??? a hotbed of star formation less than 1 million years old! Webb’s near-infrared sensitivity allowed astronomers to identify three low-mass objects. These are so small that their cores will never be able to fuse hydrogen like full-fledged stars.

    • A collage of three images showing a dusty nebula. The left two-thirds of the collage is taken up by an image of the nebula in visible light. The remaining third is taken up by two other images, one atop the other, in near-infrared. Wispy plumes appear to fly off from the pillar toward the sides amid blue clouds of the same material, which are whiter near the pillar. There are many white stars spread throughout. Two separate, white squares, tilted about 30 degrees, outline two areas in the pillar. Both images contain a mixture of reds, blues and browns, and show red, blue, and white stars.
    • A collage of four images showing a dusty nebula. Two-thirds of the collage is taken up by a single image of the nebula, while the remaining third shows three insets stacked on top of each other. In the largest image at left, there is an orange and yellow fang-like cloud of matter that cuts the image in two. There are a number of bright blue and red points of light spread throughout, three of which are circled in white and labeled with a number from one to three. Each circle magnifies an individual object and contains a single, fuzzy point of light in the middle.

  • Our ESA/Hubble Picture of the Week features a spiral paired with a prominent star! ? ?? The galaxy and the star appear close – but the star is 7109 light-years away in the Milky Way galaxy while the galaxy, NGC 4900, is 45 million light-years away! ?? This image combines data from two instruments on the NASA/ESA Hubble Space Telescope: the Advanced Camera for Surveys and the older Wide Field and Planetary Camera 2. The data used here were taken more than 20 years apart for two different observing programmes! ?? Both programmes aimed to understand the death of massive stars. In one, researchers studied the sites of past supernovae. In the other, they laid the groundwork for studying future supernovae ?? Read more: https://ow.ly/Mz3950VcAl0 ?? ESA/Hubble & NASA , S. J.

    • A spiral galaxy seen face-on. Broken spiral arms made of blue patches of stars and thin strands of dark dust swirl around the galaxy’s centre, forming a broad, circular disc. An extended circular halo surrounds the disc. The centre is a brightly-glowing, stubby bar-shaped area in a pale yellow colour. A bright star in our own galaxy, with long cross-shaped diffraction spikes, is visible atop the distant galaxy.

  • ?? The NASA/ESA/CSA James Webb Space Telescope has snapped an actively forming star system! ?? Near-infrared light captured by Webb shows incredible detail and structure in Lynds 483 (L483). Two actively forming stars are responsible for the ejection of gas and dust gleaming in orange, blue, and purple in this representative colour image. ?? These central protostars ?? have been ejecting gas and dust over tens of thousands of years, spewing it out as fast jets and slower outflows. When more recent ejections hit older ones, the material can tangle together. ?? Over time, chemical reactions within these ejections and the surrounding cloud have produced a range of molecules, including carbon monoxide, methanol, and other organic compounds.

    • At the centre is a thin vertical cloud known as Lynds 483 (L483) that is roughly shaped like an hourglass with irregular edges. The lower lobe is slightly cut off. The top lobe is seen in full, petering out at the top.

  • ?? The NASA/ESA/CSA James Webb Space Telescope has shed light on a starless super-Jupiter! ?? SIMP 0136 is a rapidly rotating, free-floating object roughly 13 times the mass of Jupiter. As the brightest object of its kind in the northern sky, it has long been an ideal target for exo-meteorology ??? ?? Astronomers knew that it varies in brightness, with patchy cloud layers that rotate in and out of view ?? although they didn’t know whether there were other factors at play. ?? Webb’s #NIRSpec and #MIRI monitored a broad spectrum of infrared light emitted by SIMP 0136 over two full rotations, detecting variations in cloud layers, temperature, and carbon chemistry. ?? This showed that SIMP 0136’s variations in brightness were due to a complex combination of atmospheric factors – not by clouds alone!

  • A very special day is coming up for the NASA/ESA Hubble Space Telescope ?? 24 April marks 35 years since Hubble was sent into orbit! Now, Hubble is more active and productive than ever. To celebrate its anniversary, ESA/Hubble has released a commemorative 2025 calendar, ‘Highlights from 35 Years of Discovery’, which looks back over a selection of Hubble’s most incredible images.

  • The spiral galaxy NGC 2283 ?? is one 55 star-forming galaxies observed by the NASA/ESA/CSA James Webb Space Telescope for a programme aiming to reveal the relationship between stars, gas, and dust in these galaxies. All 55 galaxies are close enough for Webb to see individual star clusters and gas clouds. These can be seen in this image outlining NGC 2283’s spiral arms! #WebbSeesFarther ??

  • Our ESA/Hubble Picture of the Week features a spiral of the water snake ???? ?? NGC 5042 resides about 48 million light-years from Earth in the constellation Hydra (the water snake). It was captured in six wavelength bands, from the ultraviolet to the infrared, creating this multi-coloured portrait. ?? The galaxy’s cream-coloured centre is packed with ancient stars and its spiral arms are patched with young blue stars. Perhaps its most striking feature, however, is the collection of pink clouds spread throughout its spiral arms… ?? These are H II regions, which get their distinctive colour from hydrogen atoms that have been ionised by ultraviolet light. Only hot, massive stars ?? produce enough high-energy light to create these regions! Read more: https://ow.ly/mLPX50V97Ng ?? ESA/Hubble & NASA, D. Thilker

    • A spiral galaxy. It’s noticeably bright around the central region of its disc, then dims somewhat out to the edge where there are fewer stars. Two spiral arms circle through the disc and emerge beyond its edge, around the galaxy’s sides. Many pink spots of new star formation, as well as dark reddish strands of dust, cover the galaxy. The arms contain some speckled, blue patches containing hot stars.
