<span lang="EN">A telescope co-developed by a University of Maryland astronomer is moving from planning to building and executing the mission of visualizing cataclysmic deep-space explosions.</span>

<span lang="EN">NASA on Tuesday advanced the </span>[<span lang="EN">Ultraviolet Explorer (UVEX)</span>](https://www.uvex.caltech.edu/)<span lang="EN"> to final design and fabrication, and has scheduled it to launch by January 2031. The $590 million multi-institutional mission led by Caltech proposes to observe ultraviolet radiation from the entire sky with unprecedented sensitivity. It will also zoom in on kilonovae, which follow the collision of two neutron stars, and supernovae, which occur when massive stars explode. Astronomy Associate Professor Suvi Gezari is the mission’s dynamic universe lead, spearheading science on these transient phenomena. </span>

<span lang="EN">“It’s really exciting for us to advance to the next stage because we've put a lot of work into this initial mission-planning phase,” Gezari said. “This new ultraviolet window into the universe will yield many discoveries and will be a huge advance in our field, especially for studying energetic explosions in the universe.”</span>

<span lang="EN">The last NASA mission to image large swaths of the sky in the ultraviolet was the Galaxy Evolution Explorer, which was launched in 2003 and decommissioned in 2013. Compared with its predecessor, UVEX has greater resolution and 50-times better sensitivity, empowering astronomers to test various theories of galaxy evolution and star formation. </span>

<span lang="EN">One core area of UVEX research involves low-mass galaxies with very few metals and heavy elements. These make up the majority of galaxies in the universe but are difficult to observe through optical or infrared imaging because they are extremely faint. Researchers have discovered only about 20,000 of the 10 million to 200 million low-mass galaxies predicted to exist within roughly 300 million light-years of Earth. With UVEX, the team expects to find millions more.</span>

<span lang="EN">In addition to imaging the entire sky, UVEX will point toward specific transient sources of light, such as short-lived supernovae and kilonovae, within hours of when they’re first discovered. Using the device’s ultraviolet spectrometer, researchers can study the environment, physics and chemistry underlying these events. </span>

<span lang="EN">“For kilonovae, early UV observations provide critical information that can distinguish between models about what’s powering the early hot emission in these violent merger events,” said Gezari. “For supernovae, they radiate brightest in the ultraviolet early on, but it doesn’t last for long — only hours to days — so a fast response is really critical.” </span>

<span lang="EN">UVEX’s imaging will complement that of existing space observatories such as NASA’s </span>[<span lang="EN">Nancy Grace Roman Space Telescope</span>](https://cmns.umd.edu/news-events/news/Jackie-townsend-roman-space-telescope-physics-mission)<span lang="EN">, which visualizes the universe in infrared light, and the NSF-DOE Vera C. Rubin Observatory, which sees visible light and infrared radiation, Gezari said. </span>

<span lang="EN">“Rubin and Roman will discover many new transient phenomena, and we will provide a critical spectroscopic capability to follow up quickly to capture the fleeting information encoded in the ultraviolet,” Gezari said. “What I’m most excited for is to provide a resource for the community to trigger targeted ultraviolet observations for various transient phenomena, from supermassive black holes ripping up stars to new classes of supernovae that we don’t yet understand.” </span>
