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

An international scientific team, including members of the Instituto de Astrofísica de Canarias (IAC), has launched an ambitious program to map exoplanets located around the Neptunian Desert —a region around stars where planets the size of Neptune are very rare— in order to better understand the mechanisms of planetary system evolution and formation. This scientific expedition has delivered its first results with the observation of the TOI-421 planetary system. Analysis of this system reveals a surprisingly inclined orbital architecture, offering new insights into the chaotic history of

The Instituto de Astrofísica de Canarias (IAC) has successfully completed the integration of the scientific detector into the FRIDA (inFRared Imager and Dissector for Adaptive Optics) instrument, an integra-field camera and spectrograph designed to work with the adaptive optics system of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical and infrared telescope, located at the Roque de los Muchachos Observatory in La Palma. The integration was carried out in the laboratories of the National Autonomous University of Mexico (UNAM) in Mexico City by a team from the IAC
