The calibration tests consisted of series of 10–100 acquisitions (typically with an exposure time of 10–40 s plus a read-out time for the charge-coupled-device (CCD) detector of 30 s) with LFC light ...

This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering ...

A spectrograph is a device that separates the incident light from an object into a frequency spectrum and measures the amount of radiation at each wavelength. The device operates by dispersing or ...

More than 500 astronomers from all over Europe, including members of Catalan universities and research centers—the UPC and the ICCUB—have designed and planned a total of five years of operations for ...

In a significant development, Indian Scientists have indigenously designed and developed a low-cost optical spectrograph, which is capable of locating sources of faint light from distant celestial ...

Gemini South, one of the world’s most productive and powerful optical-infrared telescopes, received a major capability boost with the successful installation of a new high-resolution spectrograph ...

Finding life beyond our solar system goes beyond measuring an exoplanet's size, as rocky, Earth-sized worlds might not have the conditions for life as we know it. While exoplanets can be directly ...

The Hubble Space Telescope was launched by the space shuttle Discovery on April 24, 1990. Avoiding distortions of the atmosphere, Hubble has an unobstructed view peering to planets, stars, and ...

The international collaboration developing the Prime Focus Spectrograph (PFS) has passed a significant testing milestone by successfully taking spectra from target stars. This is also a major step ...

An international team led by the Universities of Geneva (UNIGE) and Montreal published the first results today from the NIRPS spectrograph installed on the European Southern Observatory's (ESO) ...
