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

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has achieved its first scientific results, with four articles published today in the journal Astronomy & Astrophysics and one more accepted for publication. The data confirm its ability to detect Earth-like planets in the infrared for the first time with a precision better than one metre per second. One of the papers, led by IAC researcher Alejandro Suárez Mascareño, confirms the presence of a

Astronomers have used telescopes around the world, includingthe Gran Telescopio Canarias (GTC or Grantecan) at the Roque de los Muchachos Observatory on La Palma, to study the asteroid 1998 KY26, revealing it to be almost three times smaller and spinning much faster than previously thought. The asteroid is the 2031 target for Japan’s Hayabusa2 extended mission. The new observations offer key information for the mission’s operations at the asteroid. “We found that the reality of the object is completely different from what it was previously described as,” says astronomer Toni Santana-Ros, a
