Almost a decade after starting observations of the sky in the northern hemisphere, the QUIJOTE Collaboration has presented an initial series of 6 scientific articles, giving the most accurate description we have of the polarization of the emission of the Milky Way in the microwave range. This is a window of observation not previously explored, which provides complementary information to that obtained previously by space missions (Planck and WMAP) dedicated to the study of the cosmic microwave background radiation (CMB), the fossil radiation left behind by the Big Bang. The new results allow

The Unit of Communication and Scientific Culture (UC3) of the Instituto de Astrofísica de Canarias (IAC), with the collaboration of the Museum of Science and the Cosmos (Museums of Tenerife), has edited two astronomical wall calendars with astronomical events for the year 2023, which can be consulted and downloaded in digital format and picked up in physical form at the IAC headquarters in La Laguna. The astronomical images that illustrate them have been obtained by the astrophotographer Daniel López (El Cielo de Canarias). The Wall Calendar ( link to the document pdf) The Poster calendar (

An international team of researchers, among them scientists from the Instituto de Astrofísica de Canarias (IAC), has confirmed the primitive origen of an old star in the Milky Way, using the ESPRESSO instrument. The stars with the least content of metals are considered to be the oldest in the Milky Way, formed only a few hundred million years after the Big Bang, which is a small fraction of the age of the universe. These stars are “living fossils” whose chemical composition gives clues about the first stages of the evolution of the universe. The star SMSS1605-1443 was discovered in 2018 and

The infrared camera DRAGO-2, developed by the team at IACTEC-Space and integrated into the satellite carrier ION-scv007 Glorious Gratia of the Italian company D-Orbit is now in orbit around the Earth after its successful launch yesterday on board a Falcon 9 rocket of Space-X. The Transporter-6 mission of SpaceX lifted off without a hitch at 14: 56 UT from platform 40 of the Space Force Station at Cape Canaveral, Florida (USA). Yesterday afternoon students, families, the media and IACTEC personnel were in the viewing room which had been installed in the multi-use area of IACTEC in the

Overlaps at the Frontiers of Astrophysics, Cosmology and Particle Physics at the XXXIII Canary Islands Winter School of Astrophysics The type of matter we are made of and we are familiar with accounts only for 5% of the Universe. The rest is the so called Dark Universe, made of something named dark matter ( 27%), and something named dark energy (68%), two big mysteries. This year the Winter School of Astrophysics of the Instituto de Astrofísica de Canarias (IAC) has gathered renowned researchers on three fundamental fields: Astrophysics, Cosmology and Particle Physics, which converge into
