The first of six projects led by Carnegie-affiliated astronomers will, for the next three days, use the James Webb Space Telescope to make some of the most-accurate measurements ever taken of the chemistry of very early galaxies—studying light that traveled 10 billion years to reach us. Carnegie’s Gwen Rudie and Allison Strom, formerly a Carnegie-Princeton…
Between July 13 and 15, 2022, the second version of the National Astronomy Education Congress was held by the worldwide network of National Astronomy Education Coordinators (NAEC) in Chile and addressed the main challenges of strengthening astronomy education in the country. The Las Campanas Observatory (LCO) was part of this event, giving workshops on the…
With a large number of observations and models of type II supernovae, a statistical analysis was performed on the physical properties that most influence the observational diversity of this type of event. Supernovae (SNs) are very energetic stellar explosions that mark the end of the evolution of some stars and are divided into two main…
Every June 30 has been known as International Asteroid Day since 2016. The United Nations General Assembly set this date to commemorate the impact of an asteroid in Tunguska in Siberia (Russian Federation) on June 30, 1908, and to raise awareness about the danger of asteroid impact. Last Sunday, June 26, 2022, Las Campanas Observatory,…
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…
