The James Webb Space Telescope’s snapshots of a giant world orbiting another star show that the observatory is performing even better than expected and that its best exoplanet images are yet to come

allowing the best possible contrast at the background location. We used a grid-based approach to optimize the spatial (x,y) location and flux scaling of the Eps Eri images and, thereby, to provide the best match to the PSF wing structure of the Eps Ind images. We then subtracted this b...
That means you can virtually take the telescope with you and share your photos on social media. Imagine: space telescope photos over the Grand Canyon, in the center of your home town, or perhaps floating next to your best friends in the park. ...
These images are part of the Cosmic Evolution Early Release Science (CEERS) survey, which consists of images of 10 different patches of sky by JWST's Near-Infrared Camera (NIRCam). JWST's Near-Infrared Spectrograph (NIRSpec) joins in observations of six of those patches, while the space ...
“JWST has delivered such stunning images of this region that sources are literally popping out in every small patch of the observed sky,” said Santosh Harish, a postdoctoral research associate at RIT. “What were thought to be compact objects based on the best images we had so far, the ...
I think the reason for the wish to use an Arianne 5 is that the mission planners believe that they will not have the shuttle and the need for a large diameter in payload is best suited to an Ariane. Chan eil mi aig a bheil ùidh ann an gleidheadh an status quo; Tha mi airson...
The revolutionary aspect of this new observatory is perhaps best revealed by the exceptional spectroscopic capabilities offered by JWST. Occasionally referred to as a molecular machine, JWST is uniquely primed for searching and detecting a plethora of gases, ices, and mineral features, thanks to the...
The commonly accepted model of the first type is the standard ΛΛCDM cosmological model, which best fits observational data among other expanding-Universe models 4. Those other models played an important role in the past for the development of the methods of observational cosmology. Therefore, per...
