designated SN 2004ca. Type Ia supernovae are the kind used by astronomers to measure the expansion of the universe. Analysis of the initial data, plus a separate observation of the newly discovered ...

The Nearby Supernova Factory, an international collaboration of astronomers and astrophysicists, has announced that SNIFS, the Supernova Integral Field Spectrograph, achieved “first light” during the ...

NASA’s Europa Clipper spacecraft has recorded important new observations of the interstellar comet 3I/ATLAS using its Southwest Research Institute-led Ultraviolet Spectrograph (UVS). In July, 3I/ATLAS ...

The international collaboration developing the Prime Focus Spectrograph (PFS) has marked a significant testing milestone by successfully taking spectra of targeted stars. The PFS will be mounted on ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

A communications delay timed out the instrument’s flight software, and some planned observations will have to be rescheduled, NASA says. Reading time 2 minutes NASA says the Webb Space Telescope’s ...

The main function of a telescope spectrograph is to separate light into its component colours (or wavelengths) to reveal information about the chemical content, temperature and motion of distant ...

The James Webb Space Telescope has observed the best evidence yet for emission from a neutron star at the site of a well-known and recently-observed supernova known as SN 1987A. At left is a NIRCam ...
