Colorado Ultraviolet Transit Experiment (CUTE) is a small UV space telescope to study selected exoplanets. [1] It was launched as a rideshare on the Atlas V that launched Landsat 9 on September 27, 2021. [1] Designed to operate for at least 8 months and study 10 exoplanets, CUTE remains operational as of December 2023, 27 months after launch.
UV observations can also provide essential information about the evolution of galaxies. They can be used to discern the presence of a hot white dwarf or main sequence companion in orbit around a cooler star. [3] [4] The ultraviolet universe looks quite different from the familiar stars and galaxies seen in visible light.
GALEX used the first ever UV light dichroic beam-splitter flown in space to direct photons to the Near UV (175–280 nanometers) and Far UV (135–174 nanometers) microchannel plate detectors. Each of the two detectors has a 65 mm (2.6 in) diameter. The target orbit is 670 km (420 mi) circular and inclined at 29.00° to the equator.
These can not travel a long distance through the atmosphere, meaning that they can only be observed high in the atmosphere or in space. Several types of astrophysical objects emit X-rays, from galaxy clusters , through black holes in active galactic nuclei to galactic objects such as supernova remnants , stars , and binary stars containing a ...
Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
However, scientists are now copying a technique used by lobster eyes to gain better X-ray vision.Instead of refraction, or the bending of light by a lens, lobsters see using reflection.
The importance of this project is confirmed in [5] which says that the discovery rate for UV variable sources and UV transients could increase by several orders of magnitude with the launch of a space-based UV mission with a wide field of view (several deg2) and [6] which states that "The proposed ULTRASAT mission could discover hundreds of ...
