The system lies within the Milky Way, about 1,300 light-years from Earth, in the constellation Scorpius. WASP-17 b, also called Ditsö̀, is a hot gas giant that orbits its star at a distance of just 0.051 AU (about 4.75 million miles, or one-eighth the distance between Mercury and the Sun), completing one full circuit in about 3.7 Earth-days. This artist's concept shows what the exoplanet WASP-17 b could look like. Astronomers used ASKAP to detect the FRB in June 2022 and determine where it originated. Radio telescopes have helped astronomers trace these quick cosmic flashes, including the ASKAP array of radio telescopes, located on Wajarri Yamaji Country in Western Australia. Many FRBs release super bright radio waves lasting only a few milliseconds at most before disappearing, which makes fast radio bursts difficult to observe. The burst, named FRB 20220610A, lasted less than a millisecond, but in that fraction of a moment, it released the equivalent of our sun’s energetic emissions over the course of 30 years, according to a study published Thursday in the journal Science. The first FRB was discovered in 2007, and since then, hundreds of these quick, cosmic flashes have been detected coming from distant points across the universe. The fast radio burst is one of the most distant and energetic ever observed.įast radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves with unknown origins. Astronomers have detected a mysterious blast of radio waves that have taken 8 billion years to reach Earth.
