Researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have discovered the remains of a planet inside a disc of debris circling a white dwarf. Thought to be rich in heavy metals iron and nickel which helped it survive destruction of its planetary system. This work, has been published today in Science magazine.

Researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of Cambridge have detected lithium in a primitive star in our galaxy. The observations were made at the VLT, at the Paranal Observatory of ESO in Chile.

A new project from the Instituto de Astrofísica de Canarias (IAC) has been chosed to be carried out in the Science Lab in the seventh edition of the Global Azure Bootcamp. This annual event occurs simultaneously in over 100 countries, and brings together professionals and experts in Internet technology, and in the Microsoft Cloud.

The first results on the analysis of the images of Bennu obtained using OCAMS, OVIRS, and OTES instruments on-board NASA’s OSIRIS-REx spacecraft have been published today in a paper on Nature Astronomy, co-authored by four researchers of the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL).

Stars with masses between one and eight times the mass of the Sun evolve along the asymptotic giant branch (AGB) before ending their lives as white dwarfs. It is during this rapid but crucial phase when the stars expand to huge dimensions and cool down, losing a major fraction of their mass due to the strong stellar winds. The low temperature and high density of the winds provide ideal conditions for the condensation of dust grains in their circumstellar envelopes. The dust produced by the stars in their AGB phase and expelled into the interstellar medium is important for the lives of the

The study, which has combined images from the Hubble Space Telescope with spectroscopic observations from the GTC, has confirmed the existence of a new example of a gravitational lens, a phenomenon predicted by Albert Einstein's theory of General Relativity.
