NGC 1637
NASA’s Webb Telescope Locates Former Star That Exploded as Supernova
The main image at left shows a view of spiral galaxy NGC 1637 from NASA’s James Webb Space Telescope and Hubble Space Telescope. Hubble’s shorter-wavelength data is represented in blue and green, while Webb’s longer-wavelength data is represented in green and red. Panels at the right show a...
Circinus Galaxy
Circinus Galaxy (Hubble and Webb)
This image from NASA’s Hubble Space Telescope shows a full view of the Circinus galaxy, a nearby spiral galaxy about 13 million light-years away. The inset highlights a Webb close-up of the galaxy’s core, where infrared observations pierce through dust to reveal hot material feeding its central...
Helix Nebula
Helix Nebula (VISTA, Webb)
This image of the Helix Nebula from the Visible and Infrared Telescope for Astronomy (left) shows the full view of the planetary nebula, with a box highlighting the smaller field of view from NASA’s James Webb Space Telescope’s NIRCam (right).
Helix Nebula
Helix Nebula (NIRCam Image)
A new image from NASA’s James Webb Space Telescope of a portion of the Helix Nebula highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment. Webb’s image also shows the stark transition between the hottest gas to...
Sextans A
Sextans A (NIRCam Only Image)
Images from NASA’s James Webb Space Telescope of the dwarf galaxy Sextans A reveal polycyclic aromatic hydrocarbons (PAHs), large carbon-based molecules that can be a signifier of star formation. Sextans A is a nearby galaxy that is chemically primitive, meaning it has a very low content of...
Sextans A
Sextans A Unannotated (NIRCam and MIRI image)
Images from NASA’s James Webb Space Telescope of the dwarf galaxy Sextans A reveal polycyclic aromatic hydrocarbons (PAHs), large carbon-based molecules that can be a signifier of star formation. Sextans A is a nearby galaxy that is chemically primitive, meaning it has a very low content of...
Sextans A
Sextans A Context image (Webb and KPNO)
NASA’s James Webb Space Telescope’s image of a portion of the nearby Sextans A galaxy is put into context using a ground-based image from the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory. The image from Webb shows the galaxy in both near- and mid-infrared light, while...
Sextans A
Sextans A PAHs Pull-out (NIRCam and MIRI image)
Images from NASA’s James Webb Space Telescope of the dwarf galaxy Sextans A reveal polycyclic aromatic hydrocarbons (PAHs), large carbon-based molecules that can be a signifier of star formation. The inset at the top right zooms in on those PAHs, which are represented in green. In Sextans A,...
CEERS
New Galaxy Population Pull-outs in CEERS Field (NIRCam Image)
Four of the nine galaxies in the newly identified “platypus” sample were discovered in NASA’s James Webb Space Telescope’s Cosmic Evolution Early Release Science Survey (CEERS). One key feature that makes them distinct is their point-like appearance, even to a telescope that can capture as much...
Egg Nebula
Egg Nebula
NASA's Hubble Space Telescope reveals the clearest view yet of the Egg Nebula — a pre-planetary nebula of gas and dust created by a dying, Sun-like star. These newest observations, taken with Hubble's Wide Field Camera 3, include infrared data. Powerful beams of starlight blast out of the inner...
asteroid 2024 YR4
Asteroid 2024 YR4 (NIRCam and MIRI)
NASA’s James Webb Space Telescope recently captured these images of the asteroid 2024 YR4 using both its NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument). Data from NIRCam shows reflected light, while the MIRI observations show thermal light. Using the NIRCam data, along with...
Sagittarius B2
Sagittarius B2 (MIRI Image)
Webb’s MIRI (Mid-Infrared Instrument) shows the Sagittarius B2 (Sgr B2) region in mid-infrared light, with warm dust glowing brightly. To the right is one clump of clouds that captured astronomers’ attention. It is redder than the rest of the clouds in the image and corresponds to an area that...

ALMA Sees Super Stellar Nurseries at Heart of Sculptor Galaxy
What is the recipe for starburst? Astronomers studied NGC 253 with ALMA to find out. These new ALMA data reveal a diffuse envelope of carbon monoxide gas (shown in red), which surrounds stellar nurseries -- regions of active star formation (in yellow). By dissecting these regions with ALMA,...
