A University of Oklahoma doctoral student, graduate and undergraduate research assistants, and an associate professor in the Homer L. Dodge Department of Physics and Astronomy in the University of Oklahoma College of Arts and Sciences are lead authors on a paper describing a changing-look blazar - a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy. The paper is published in

NASA s Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore a vast array of celestial objects and phenomena, bringing us closer to solving many pressing cosmic mysteries. As the telescope s eyes, Roman s detectors will enable all of the mission s science, said John Gygax, the focal plane system manager for the Roman Space Telescope at NASA s Goddard Space Flight Center in Greenbelt, Maryland. Now, based on our testing results, our team can confirm these infrared detectors meet all the requirements for Roman s purposes.

An international team of astrophysicists led by the Stellar Astrophysics Group of the University of Alicante (UA), the Instituto de Astrofísica de Canarias (IAC), and the University of Valparaíso (Chile) has discovered a massive cluster of stars of intermediate age in the direction of the Scutum constellation. This object, which has been named Valparaíso 1, lies some seven thousand light years away from the Sun, and contains at least fifteen thousand stars. To detect it, observations have been combined from ESA s Gaia satellite, and various ground-based telescopes, including the Isaac Newton Telescope at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The result has been published in
Sandia researcher Humberto Tito Silva III has been named Engineer of the Year by AIAA, the world s largest aerospace technical society. Silva s work improved failure-rate predictions of aerospace flight systems as they reenter Earth s atmosphere. The work helps direct engineers to attack the worst problems first for reentry rockets, spaceships and satellites.
The German-French Cooperation Programme GENESIS describes the complex structure of the interstellar medium using a new mathematical method. The dispersion of interstellar turbulence in gas clouds before star formation unfolds in a cosmically small space.
