Exoplanets discovered6/15/2023 Due to its large orbit, the planet candidate would not cross in front of the binary partner for another 70 years, meaning it could take decades to confirm the observation. However, researchers will have to wait a long time to confirm whether they have discovered an extragalactic exoplanet. This allows exoplanets to be detected at much greater distances. The region creating bright X-rays is small, and so a planet passing in front of it would be easy to spot, as it would block most, or all, of the X-rays. Ryan Foley/UC Santa Cruz/ESA/NASAĮxplosive star death witnessed by Hubble could help develop an early warning system These observations allowed researchers to understand what was happening to the star just before it died, and may provide astronomers with an early warning system for other stars on the brink of death. Hubble probed the material very close to the supernova that was ejected by the star in the last year of its life. Along with other space- and ground-based telescopes, Hubble delivered a ringside seat to the first moments of the ill-fated star's demise, giving a comprehensive view of a supernova in the very earliest stage of exploding. Researchers quickly trained NASA's Hubble Space Telescope on the aftermath. Astronomers recently witnessed supernova SN 2020fqv explode inside the interacting Butterfly galaxies, located about 60 million light-years away in the constellation Virgo.
