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 ...
The use of tardigrades in space, first proposed in 1964 because of their extreme tolerance to radiation, began in 2007 with the FOTON-M3 mission in low Earth orbit, where they were exposed to space's vacuum for 10 days, and reanimated, just by rehydration, back on Earth. In 2011, tardigrades were on board the International Space Station on STS-134.
The study involved 24 astronauts from the U.S., European and Japanese space agencies who traveled aboard the International Space Station for up to 26 weeks. Study documents headaches experienced ...
Spektr-UV, also known as World Space Observatory-Ultraviolet (WSO-UV), is a proposed ultraviolet space telescope intended for work in the 115 nm to 315 nm wavelength range. [ 3 ] [ 4 ] It is an international project led by Russia (Roscosmos), with participation from Spain and Japan.
