The Vera Rubin Observatory, with its wide-field, high-resolution, and rapid imaging capabilities, is poised to revolutionize our understanding of the universe by solving cosmic puzzles such as the nature of dark energy, the Hubble tension, and discovering new transient phenomena through time-domain astronomy, while also enabling rapid follow-up observations with other telescopes.
NASA's Fermi and Swift satellites detected the brightest cosmic event ever recorded, known as the BOAT, a long gamma-ray burst possibly originating from a massive star's core collapse. This event showcases the power of Time-Domain and Multimessenger Astronomy, allowing scientists to study dynamic processes in the universe. Follow-up observations from over 150 telescopes provided insights into the event's origin and composition, while newer signals like GRB 230307A offer further mysteries and opportunities for study. NASA plans to launch new satellites and missions to continue monitoring transient events and unraveling the universe's secrets.
NASA's Nancy Grace Roman Space Telescope, set to launch in 2027, will conduct a Galactic Bulge Time-Domain Survey, monitoring hundreds of millions of stars in the Milky Way to detect flickers that indicate the presence of planets, distant stars, icy objects, black holes, and more. The mission aims to set a new record for the farthest-known exoplanet and explore the center of our galaxy, providing insights into different galactic neighborhoods and the formation and evolution of planetary systems. The survey will also study brown dwarfs, neutron stars, stellar-mass black holes, and Kuiper belt objects, while conducting stellar seismology studies on a million giant stars.
NASA's Nancy Grace Roman Space Telescope, set to launch in 2027, will provide an unprecedented view into the heart of the Milky Way galaxy. The mission aims to monitor hundreds of millions of stars, searching for flickers that indicate the presence of planets, distant stars, icy objects in our solar system, and isolated black holes. By conducting a long-term sky monitoring survey, the telescope will contribute to time-domain astronomy, studying how the universe changes over time. The mission will focus on the Milky Way's Galactic Bulge, using infrared vision to penetrate dust clouds and reveal the crowded central region of our galaxy. Roman's observations are expected to uncover thousands of exoplanets, including those in the habitable zone, as well as brown dwarfs, neutron stars, and Kuiper belt objects.
