Using observations made with the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has confirmed variations in morning and evening atmosphere of the exoplanet WASP-39 b, about 700 light-years away from Earth. The research has revealed differences in temperature and atmospheric pressure, as well as indications of different cloudiness and winds that could reach thousands of miles per hour. The results are published in Nature. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but

An international research team, with participation by the Instituto de Astrofísica de Canarias (IAC) shows that the satellite galaxy NGC 5195 has passed twice through the disc of the Whirlpool Galaxy (M51), in relatively recent times, stimulating star formation, and defining the structure of its arms. The research is published in the prestigious The Astrophysical Journal. The Whirlpool Galaxy M51, is a ”grand design” spiral galaxy: its spiral form is dominated by two well defined arms. Discovered by Charled Messier in 1771 M51 lies some 31 million light years from Earth, As it is face-on

The European Southern Observatory (ESO) has signed an agreement with an international consortium of institutions, including the Instituto de Astrofísica de Canarias (IAC), the Instituto de Astrofísica de Andalucía (IAA) and the Centro de Astrobiología de Madrid (CSIC-INTA), for the design and construction of ANDES, the ArmazoNes high Dispersion Echelle Spectrograph. The instrument will be installed on ESO’s Extremely Large Telescope (ELT). It will be used to search for signs of life in exoplanets and look for the very first stars, as well as to test variations of the fundamental constants of
