The mode uses the telescope's NIRISS (Near Infrared Imager and Slitless Spectrograph) as an interferometer. It's called Aperture Masking Interferometry (AMI) and it allows the JWST to reach its ...

e.g., using the F200W/F277W filters or grism of NIRCAM/NIRISS in order to find high redshift (z ≫ 10) galaxies, cool red/brown dwarf substellar objects, solar system objects, and observations of ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. The NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) captured this ...

As such, scientists recently turned the James Webb Space Telescope's (JWST) powerful gaze towards 2024 YR4, capturing the object in both visible and thermal light. The team measured the asteroid ...

What sets GJ 9827 d apart is its atmosphere's composition. By combining JWST/NIRISS and HST data, Piaulet-Ghorayeb showed that, unlike the hydrogen-dominated atmospheres of larger planets ...

Using the James Webb Space Telescope (JWST), astronomers have observed enigmatic rings in the planetary nebula NGC 1514, visible in the mid-infrared band. Results of the new observations ...

The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a blistering 19-hour orbit. Scientists using the James Webb Space Telescope ...

The James Webb Space Telescope has observed that most galaxies in the deep universe rotate in the same direction, with about two-thirds rotating clockwise and one-third counterclockwise.

The team combined data from JWST’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) with previous Hubble Space Telescope (HST) observations. This confirmed the presence of a dense ...
