    IAC y ULL led the identification of the longest orbital period exoplanets among those transiting young stars
    An international collaboration of astronomers led by the Universidad de La Laguna (ULL) and Instituto de Astrofísica de Canarias (IAC) has identified two intriguing, humongous but light planets orbit ing HD 114082. This star is only 15 million years old, this is, much younger than the Sun (4.6 billion years old) , spin s 15 times faster , has 28% more mass , and is about one thousand degrees hotter and almost four times more luminous. Its planets receive about 200 times more light and heat than Jupiter. The study, which involved separating the faint planetary signal from the stellar one

    Press release
    Gran Telescopio Canarias observations confirm that Hayabusa2's asteroid target is smaller and faster than expected
    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
