NGC 3137
Starry spiral in a familiar neighbourhood
In this ESA/Hubble Picture of the Month, a spiral galaxy glittering with star clusters is the centre of attention. NGC 3137 is located 53 million light-years away in the constellation Antlia (The Air Pump). As a nearby spiral galaxy, this target offers astronomers an excellent opportunity to...
Trifid Nebula
Trifid Nebula (Wide Field Camera 3 Image)
The colours in this image from the NASA/ESA Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5000 light-years from Earth. The top left, where it is bright blue, has the smallest amount of dust. Here, powerful ultraviolet light stripped...
NASA's SPHEREx Observatory Maps Stars and Dust in Cygnus
An observation made by NASAs SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) shows a dusty infrared starfield in the Cygnus region of the sky.
NASA's SPHEREx Observatory Maps Interstellar Ice in Milky Way
An observation made by NASAs SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) shows the chemical signatures of water ice (shown in bright blue) and polycyclic aromatic hydrocarbons (orange) in Cygnus X, one of the most active and turbulent...

Aiming at a cosmic tarantula
It might look like we started a space war, but we didn't. This isn't a scene from Star Wars either. What we're looking at is the Tarantula Nebula. And those beams come from the lasers installed on the telescopes that comprise ESO's Very Large Telescope Interferometer. The VLTI combines the...
Pictor II
Pictor II ultra-faint dwarf galaxy
This image shows stars in the ultra-faint dwarf galaxy, Pictor II. Pictor II is a satellite galaxy of the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way, and is located in the constellation Pictor. The system is made up of several thousand stars and is more than ten...
Pictor II
Star PicII-503 in Pictor II ultra-faint dwarf galaxy
This image shows the star PicII-503, with the lowest iron content ever measured outside of the Milky Way. With less than 1/40,000th the amount of iron as the Sun, PicII-503 is the clearest example of a star within a primordial system that preserves the chemical enrichment of the Universe’s...
Crab Nebula
Crab Nebula (2024 Hubble image)
The NASA/ESA Hubble Space Telescope has captured the intricate detail of the Crab Nebula with its Wide Field Camera 3. The colours in the image trace Hubble’s detection of oxygen and sulfur gases in the nebula at varying densities and energies. The blue areas are the hottest and lowest density....
Crab Nebula
Crab Nebula (new image from 1999/2000 data)
This newly processed image comes from data originally captured by the NASA/ESA Hubble Space Telescope in 1999 and 2000. Updated image-processing technology allows for this archival image to be best compared with more recent data, including those captured by Hubble itself. Hubble received a new...
Where spiral arms and star formation meet
A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new ESA/Hubble Picture of the Month image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified...
IC 486
IC 486 (wide-field view)
IC 486 lies in the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, it features a bright central bar-shaped structure from which its spiral arms unfurl, wrapping around the core in a smooth, almost ring-like pattern. This...
Andromeda
Hubble M31 PHAT+PHAST Mosaic
This is the largest photomosaic ever assembled from Hubble Space Telescope observations. It is a panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away. It took over 10 years to make this vast and colorful portrait of the galaxy, requiring over 600 Hubble...

Hydra A
Chandra Ploughs Up a Snake In Hydra A
A cluster of galaxies in the constellation Hydra. The Chandra X-ray image of Hydra A, a galaxy cluster 840 million light years from Earth, shows strands of 35-40 million degree Celsius gas embedded in a large cloud of equally hot gas that is several million light years across. Also a bright...
