The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work led by Carnegie’s Andrew Newman demonstrates a new technique for identifying the precursors of the most extreme galactic environments. The team’s findings are published in Nature. Like all of us, galaxies are shaped and molded by their surroundings.…
Last Sunday, May 29, Las Campanas Observatory (LCO) participated in the activity organized by the National Astronomical Observatory of the University of Chile, located in Cerro Calán (Las Condes, Metropolitan Region) for Heritage Day. Around 6,300 people attended the event. Thanks to the outreach alliance that LCO has with the Giant Magellan Observatory (GMT) and…
The “Conciencia Astronomía” Mobile Laboratory, operated by Las Campanas Observatory in alliance with the EcoScience Foundation and the Giant Magellan Telescope (GMTO), is working to promote scientific and astronomical education among children and young people, mainly in the north of our country. In this context, on May 25 and 26, the laboratory visited the Municipal…
A team of astronomers led by University of Michigan’s Ian Roederer and including Carnegie’s Erika Holmbeck have identified the widest range of elements yet observed in a star beyond our own Sun. Their findings are published in The Astrophysical Journal Supplement Series. The researchers identified 65 elements in the star, which is called HD 222925. Of…
For the second consecutive year, Las Campanas Observatory (LCO) participated in the Paseo de la Ciencia (Science Walk) of the Puerto de Ideas Festival, held in Antofagasta between April 21 and 24, 2022. This year, the activity was face-to-face and took place at Sitio Cero, located next to Mallplaza and the Huanchaca Ruins. LCO travelled with the…
Easy reading is a methodology designed to write, or adapt, and validate a text in an accessible way, so that people with comprehension difficulties can understand what they read, highlighting in this group those with intellectual disabilities. In order to continue adapting its contents to be understood by everyone, Las Campanas Observatory launched the easy-to-read…
After two years of online activities, the Las Campanas Observatory celebrated Astronomy Day with in-person events in La Serena and Vallenar. To celebrate this science, activities are held throughout the country, focusing on contingent issues such as light pollution. The activities were aimed at students and the community in general and organized in conjunction with…
After 2 years of virtual operation, the Mobile Laboratory “Conciencia Astronomía”, known as LabMóvil, is back on the road and back to its face-to-face activities in this science thanks to a recent collaboration between the Giant Magellan Telescope (GMTO) and the EcoScience Foundation with Las Campanas Observatory (LCO), part of the Carnegie Institution for Science.…
The celebration of Astronomy Day, future training for entrepreneurs in the rural sectors of Domeyko, Incahuasi and Cachiyuyo, or actions to avoid light pollution, were some of the topics that the mayor of Vallenar, Armando Flores, discussed with the director of Las Campanas Observatory, Leopoldo Infante, and which will be fundamental for the collaborative work…
Stars have a life cycle, and their end depends mainly on their initial mass. One of these endings is supernovae, highly energetic events that cause the parent star to disappear. Thirty-five years ago, on the night of February 24, 1987, astronomer Ian Shelton and Instrument and Operations Specialist Oscar Duhalde discovered a bright supernova in…
