Chemical history of a star cluster in the inner regions of the Milky Way galaxy revealed

An international group of researchers, including astronomers from the Universidad Católica del Norte have conducted the first investigation of the chemical properties of the ancient globular cluster Tonantzintla 1, also known as NGC 6380. The researchers worked with data obtained with the Irénée du Pont telescope at Las Campanas Observatory. Globular clusters are symmetric, compact…

Following the explanation of the most common planets in the galaxy

A Carnegie-led survey of exoplanet candidates identified by NASA’s Transiting Exoplanets Satellite Survey  (TESS) is laying the groundwork to help astronomers understand how the Milky Way’s most common planets formed and evolved, and determine why our Solar System’s pattern of planetary orbits and sizes is so unusual. The survey is using TESS data and observations…

Asteroid is observed again inside the orbit of Venus

During sunrise on July 18-19, 2021, from the Baade telescope at Carnegie Institution for Science’s Las Campanas Observatory, Peter Senchyna (Carnegie Observatories postdoctoral researcher) and Bryce Bolin (from Caltech) observed asteroid 2020AV2. This asteroid, discovered in 2020, is the only one known to revolve around the Sun in an orbit smaller than the orbit of…

Cosmic cartographers reveal diversity of star-forming galaxies in nearby universe

A team of astronomers, including Guillermo Blanc, Head of Scientific-Technical Development at Las Campanas Observatory of the Carnegie Institution for Science, used the Atacama Large Millimeter/submillimeter Array (ALMA) to complete the first census of molecular clouds in the nearby universe, revealing that contrary to previous scientific opinion, these stellar nurseries do not all look and act…

Record-Breaking Flare From Sun’s Nearest Neighbor

A team of astronomers including Carnegie’s Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an assistant professor at the University of Colorado Boulder, spotted an extreme outburst, or flare, from the Sun’s nearest neighbor—the star Proxima Centauri. One of the telescopes used in this research was du Pont telescope at Las Campanas Observatory. Their work,…

LCO launches its new astronomical outreach series

“Navegantes del Cielo Austral” is published on the observatory’s Youtube channel and explains about astronomy in a close and playful way. It also has interpretation in Chilean sign language and subtitles in Spanish and English. Astronomy is a science that is constantly evolving. Scientists all over the world are vehemently investigating to solve many of…

The extreme dance of three brown dwarfs

A team of astronomers has discovered three brown dwarfs that make a complete rotation about once every hour, making them the fastest rotating stars of this type known to date. One of the telescopes used to confirm the finding was Baade at Las Campanas Observatory. Brown dwarfs are “failed stars”. They form like stars but…
