Best Ultraviolet
The Solar Dynamics Observatory (SDO) is a space-based observatory operated by NASA. It provides continuous ultraviolet imaging of the Sun, allowing scientists to study solar flares, coronal mass ejections, and other energetic events. This data is crucial for understanding how the Sun impacts Earth’s...
The International Ultraviolet Explorer (IUE) was an astronomical satellite launched in 1978 as a collaborative project between NASA, ESA, and the UK. It was designed to obtain ultraviolet spectra of stars, galaxies, and other celestial bodies that cannot be observed from the ground due to the Earth'...
OAO-2 (Orbiting Astronomical Observatory 2), launched in December 1968, was NASA's first successful space-based ultraviolet observatory. The spacecraft carried multiple telescopes to observe the universe in ultraviolet wavelengths blocked by Earth's atmosphere. It provided critical early UV observat...
IRIS is a NASA small explorer spacecraft launched on June 27, 2013, from Vandenberg Air Force Base aboard a Pegasus XL rocket, designed to observe the Sun's chromosphere and transition region at ultraviolet wavelengths. Built by Lockheed Martin Solar and Astrophysics Laboratory and operating in Sun-...
GALEX (Galaxy Evolution Explorer) was a NASA space telescope designed to observe the sky in ultraviolet wavelengths. Launched in April 2003 aboard a Pegasus XL rocket, it conducted an all-sky survey and targeted observations to study star formation rates and galaxy evolution across cosmic time. The...
TRACE (Transition Region and Coronal Explorer) was a NASA heliophysics satellite launched in 1998 to study the Sun's magnetic fields and plasma structures. Operating in ultraviolet wavelengths, the spacecraft provided high-resolution imaging of the solar corona, capturing detailed views of coronal l...
