A greedy white dwarf star in our own Milky Way galaxy is devouring its closest celestial companion at a rate never seen before, according to an international study involving the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL). The research, published in the journal Monthly Notices of the Royal Astronomical Society , found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think the stars are locked in an "extraterrestrial tango" as they orbit each other every
ESA’s Hera mission for planetary defense performed a flyby of Mars, as part of its gravitational assistance manoeuvre to shorten its journey to the binary asteroid system Didymos. During the flyby, the spacecraft came around 5000 km from the surface of Mars, having also the opportunity to obtain images of its two moons, Deimos (during the approach) and Phobos (when departing Mars). Julia de León, Javier Licandro, and George Prodan, researchers at the Instituto de Astrofísica de Canarias, participate in this mission, successfully launched from Cape Cañaveral, Florida (USA) on October 7, 2024
