Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray astronomy. [1] Ultraviolet light is not visible to the human eye. [2]
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.
In addition to paving the way for future ultraviolet missions, the space telescope allowed astronomers to uncover mysteries about the early universe and how it evolved, as well as better characterize phenomena like black holes and dark matter. The mission was extended three times over a period of 10 years before it was decommissioned in June 2013.
A new type of stellar object has been discovered releasing energetic bursts of radio waves every 22 minutes. An unusual object has been releasing pulses of radio waves in space for decades ...

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.
While most visible in Alaska and Canada, residents from Washington to New York may also have a chance to view the Auroras Borealis on Thursday night.
Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including visible light.. The optical window is the portion of the optical spectrum that is not blocked by the Earth's atmosphere.
