The growing volume of astronomical data produced by telescopic facilities presents significant challenges and extraordinary opportunities for the scientific community. Specifically, the Canary Islands Observatories generate approximately 1 petabyte of raw images annually from nearly thirty telescope installations, both public and private. These

Galaxies undergo numerous transformative processes throughout their lifetimes that ultimately lead to the expulsion of gas and the cessation of star-forming activity. This phenomenon is commonly known as quenching, and in this study, we delve into the possibility that this process is caused by the environmental processes associated with the

TOI-6255 b (GJ 4256) is an Earth-sized planet (1.079 ± 0.065 R ⊕) with an orbital period of only 5.7 hr. With the newly commissioned Keck Planet Finder and CARMENES spectrographs, we determine the planet's mass to be 1.44 ± 0.14 M ⊕. The planet is just outside the Roche limit, with P orb/P Roche = 1.13 ± 0.10. The strong tidal force likely deforms

Submillimetre galaxies (SMGs) are some of the most extreme star-forming systems in the Universe, whose place in the framework of galaxy evolution is as yet uncertain. It has been hypothesized that SMGs are progenitors of local early-type galaxies, requiring that SMGs generally reside in galaxy cluster progenitors at high redshift. We test this

Michael Hoskin is the name of a scholar whose memory will remain forever linked to cultural astronomy. Professor of History of Science at the University of Cambridge, in the United Kingdom, where he first specialized in Isaac Newton and his 'Principia'. Later on, he would devoted a great deal of his efforts to the family of William Herschel, with

We present Gemini Multi-Object Spectrograph (GMOS) spectroscopic observations of 95 galaxies from the Arp & Madore (1987) catalog of peculiar galaxies. These galaxies have been selected because they appear to be in pairs and small groups. These observations have enabled us to confirm that 60 galaxies are indeed interacting systems. For the
