Vor 4 Tagen · A dim star in the night sky 3,000 light-years from our solar system could soon become visible to the naked eye for the first time since 1946 — and you can easily find it in the night sky.
15. Mai 2024 · An international team using robotic telescopes around the world recently spotted an Earth-sized planet orbiting an ultra-cool red dwarf, the dimmest and longest-lived of stars. When the universe grows cold and dark, these will be the last stars burning.
15. Mai 2024 · Among them are ultracool dwarfs, small and dim stars that present unique challenges for astronomers. Recently, a team of researchers discovered an Earth-sized exoplanet in orbit around an ultracool dwarf named SPECULOOS-3, located just 55 light-years away from our Sun.
15. Mai 2024 · Designed to detect dim stars for navigation purposes, the SRU is sensitive to low light. To avoid over-illumination in the image, the team used the camera to snap the nightside of Europa while it was lit only by sunlight scattered off Jupiter (a phenomenon called “Jupiter-shine”).
16. Mai 2024 · This project looks for Earth-like planets around small and dim stars using telescopes around the world. Ultracool dwarfs are not super rare. About 70 percent of the Milky Way galaxy consists of these types of stars.
