One of the biggest recent surprises in astronomy is the discovery that most stars like the Sun harbor a planet between the size of Earth and Neptune within the orbit of Mercury — sizes and orbits absent from our solar system. These ‘ super-Earths' and ` sub-Neptunes’ are the galaxy's most common planets, but their formation has been shrouded in mystery. Now, an international team of astronomers has found a crucial missing link. By weighing four newborn planets in the V1298 Tau system, they've captured a rare snapshot of worlds in the process of transforming into the galaxy's most commonAdvertised on -
Nuclear star clusters are dense and compact stellar systems, with sizes of a few parsecs, found at the centers of many galaxies. Their formation is thought to be closely connected to the assembly history of their host galaxies, and astronomers think that these clusters contain important clues about how galaxies formed and evolved over cosmic time. Recent studies suggest that different formation pathways may operate in late- and early-type galaxies, but the dominant mechanisms and their dependence on galaxy morphology remain unclear. While most observational studies have focused on early-typeAdvertised on -
Docentes y estudiantes de Tenerife han participado durante el curso en actividades orientadas al conocimiento de los observatorios de Canarias y de la investigación astrofísica. La iniciativa del Instituto de Astrofísica de Canarias (IAC), desarrollada con el apoyo del Cabildo de Tenerife, ha formado a cerca de un centenar de docentes y ha llegado a más de 3.000 estudiantes. El programa celebrará el próximo 25 de junio una jornada de formación para profesorado centrada en la iniciación a la astrofotografía. La comunidad educativa de Tenerife ha concluido una nueva edición del proyecto “Advertised on
