SPHEREx All Sky Map 2025: Stars and Galaxies
This SPHEREx image shows a selection of the infrared colors primarily emitted by stars and galaxies. SPHEREx is observing hundreds of millions of distant galaxies across the sky. Its multiwavelength view will also help astronomers measure the distance to those galaxies.

SPHEREx All Sky Map 2025
NASAs SPHEREx has mapped the entire sky in 102 infrared colors, which are invisible to the human eye but can be used to reveal different features of the cosmos. This image features a selection of colors emitted primarily by stars (blue, green, and white), hot hydrogen gas (blue), and cosmic dust...

SPHEREx All Sky Map 2025: Dust and Gas
This SPHEREx image features the infrared colors emitted primarily by dust (red) and hot gas (blue), key ingredients for forming new stars and planets. Though these clouds of material cover a massive portion of the sky, they are invisible in most wavelengths of light, including those the human eye...
Fomalhaut cs1 and cs2 (clean image)
This composite NASA/ESA Hubble Space Telescope image shows the debris ring and dust clouds cs1 and cs2 around the star Fomalhaut. For comparison, dust cloud cs1, imaged in 2012, is pictured with dust cloud cs2, imaged in 2023. The dashed circles mark the location of these clouds. When dust...

Ua ʻŌhiʻa Lani: An Image to Celebrate Gemini North’s 25th Anniversary
To celebrate 25 years since the completion of the International Gemini Observatory, students in Hawai‘i voted for the Gemini North telescope to image NGC 6820 — a striking emission nebula and open star cluster. The image was named Ua ʻŌhiʻa Lani, the Heavenly ʻŌhiʻa Rains, after the traditional...
Large Magellanic Cloud
Cloudy with a Chance of Star Formation
This Image of the Week is of the Large Magellanic Cloud (LMC), a dwarf galaxy that appears cloud-like in the Southern Hemisphere. This image was captured by photographer Petr Horálek, a NOIRLab Audiovisual Ambassador, using a wide-aperture telephoto lens on a commercial camera. Petr...
NGC 6302
Gemini South Images the Butterfly Nebula
To celebrate 25 years since the completion of the International Gemini Observatory, students in Chile voted for the Gemini South telescope to image the NGC 6302 — a billowing planetary nebula that resembles a cosmic butterfly. The International Gemini Observatory is partly funded by the U.S....
GRB 250702B
GRB 250702B host galaxy
The faint oval at the center of this image is the host galaxy of GRB 250702B — the longest gamma-ray burst that astronomers have ever observed. This image was taken on 20 July 2025 by the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S....
Field around GRB 250702B
The stellar field around the host galaxy of GRB 250702B — the longest gamma-ray burst that astronomers have ever observed. It comprises observations from the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and...
Most luminous fast blue optical transient
This composite image features X-ray, ultraviolet, optical, and near-infrared data of the luminous fast blue optical transient (LFBOT) named AT 2024wpp. The transient is the bright spot at the upper right edge of its host galaxy, which is 1.1 billion light-years from Earth.
NGC 4485
A dance of dwarf galaxies
For this new ESA/Webb Picture of the Month, the NASA/ESA/CSA James Webb Space Telescope has spied a pair of dwarf galaxies engaged in a gravitational dance. These two galaxies are named NGC 4490 and NGC 4485, and they’re located about 24 million light-years away in the constellation Canes...
Tarantula Nebula
Binary star imaged by GRAVITY+
This image, one of the first obtained with VLTI/GRAVITY+ working with four lasers, shows a binary star in the central region of the Tarantula Nebula, a star-forming region in the Large Magellanic Cloud. The binary was originally thought to be an extremely massive star, but the new observations...
