Camera Can Differentiate Between Exoplanet Light and Nearby Starlight

Facebook X LinkedIn Email
A new superconducting camera will be used in the search for exoplanets that could contain or support life. The camera’s high-contrast imaging capabilities will help overcome the challenges inherent in distinguishing the light of a planet from the light of the star that it orbits. DARKNESS (the DARK-speckle Near-infrared Energy-resolving Superconducting Spectrophotometer) is a 10,000-pixel integral field spectrograph designed to overcome the limitations of traditional semiconductor detectors. It employs IR microwave kinetic inductance detectors (MKIDs) for high-contrast imaging. The...Read full article

    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    spectrophotometer
    A spectrophotometer is a scientific instrument used to measure the intensity of light at various wavelengths in the electromagnetic spectrum, typically in the visible and ultraviolet regions. It is commonly employed in various fields such as chemistry, physics, biology, and environmental science for a wide range of applications, including chemical analysis, color measurement, and concentration determination of substances in a solution. Spectrophotometers operate by passing a beam of light...
    spectrograph
    An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
