The first data release of the SHARKS public survey, led by researchers at the Instituto de Astrofísica de Canarias (IAC), was provided to the astrophysical community today. This project, which has reached its first milestone, uses the 4-metre VISTA telescope of the European Southern Observatory (ESO) in Chile to map large portions of the sky in the near-infrared, a range of the spectrum invisible to the human eye. The near-infrared wavelength range, a type of light imperceptible to the human eye, allows us to explore regions of the Universe that are obscured by cosmic dust or are too cold to

Just as archaeology examines the ground with great care to find valuable objects which helps us to get to know ancient civilizations, astronomers look at the stars in the Milky Way in the hope of finding clues to help us understand the earliest period of development of our Galaxy. A team of researchers, in which the Instituto de Astrofísica de Canarias participates, publishes today in Nature the discovery of the oldest globular cluster remnant discovered to date. This study combines data from ESA's GAIA satellite with observations made at the Gran Telescopio Canarias, installed at the Roque

A team of researchers at the Instituto de Astrofísica de Canarias (IAC) and the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE), Mexico, has discovered lithium in the oldest and coldest brown dwarf where the presence of this valuable element has been confirmed so far. This substellar object, called Reid 1B, preserves intact the earliest known lithium deposit in our cosmic neighbourhood, dating back to a time before the formation of the binary system to which it belongs. The discovery was made using the OSIRIS spectrograph on the Gran Telescopio Canarias (GTC), at the Roque de
