Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by

The Instituto de Astrofísica de Canarias (IAC) has started its development of DRAGO-3 , the third generation of its instrument: Demonstrator for Remote Analysis of Ground Observations (DRAGO), designed for Earth observation from space in the short wave infrared region of the spectrum (SWIR). This new instrument comes after the success of DRAGO-1 and DRAGO-2 , which have proved their utility in key applications such as following volcanic eruptions, hydrological monitoring of regions affected by climate change, and the control of forest fires. Both the previous models have shown their

At the present time ground-based observatories have a wide range of instruments which can study the solar surface in the visible and infrared ranges. But it is not possible to combine these observations with those in the near ultraviolet, which cover the wavelength range from 200 to 400 nanometres, nor to maintain them for long periods due to the turbulence in the Earth’s atmosphere. In this context, the Sunrise III mission, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, “ has become the first observatory to obtain spectropolarimetric data simultaneously in the
