An international group of astronomers has used the ALMA observatory to obtain an inventory of molecular gas and dust in distant galaxies at unprecedented depth in the iconic Hubble Ultra-Deep Field (H-UDF), one of the best-studied regions of the sky. The final results are being presented in a series of papers in the Astrophysical Journal.…
The enigmatic variations of light in a binary system, located in Sagittarius constellation, could be explained by the presence of a variable gas disk around a hot star that revolves around a cooler star. These are the conclusions published in the journal Astronomy & Astrophysics and which brought by researchers from Chile, Serbia and Poland.…
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these “tidal disruption events” (TDEs) for clues to the feeding behavior of the supermassive black holes lurking at…
On Thursday, August 13, Las Campanas Observatory’s cycle of online talks began, which will feature top-level speakers, all of whom are part of the observatory’s staff. These talks will deal with various topics related to astronomy, technology, engineering and daily life at LCO. All the talks will be transmitted live through the Youtube channel of…
In August, the ten-episode online series began, broadcast live on popular digital platforms, with a Chilean sign language interpreter. Through “Stories of Inclusive Astronomy,” different specialists and professionals in the field of science and astronomy, teachers, students, and people with disabilities will tell their experiences promoting Inclusive Astronomy in Chile and the world. The connected…
Filling in the most-significant gaps in our understanding of the universe’s history, the Sloan Digital Sky Survey (SDSS) released a comprehensive analysis of the largest three-dimensional map of the cosmos ever created. The survey, of which Carnegie is an integral member, has been one of the most successful and influential in the history of astronomy.…
This series, published on Youtube, teaches and explains about astronomical objects visible at night from the southern hemisphere, in a certain month. Chile is recognized worldwide for its dark skies and its great potential for astronomical development. This is due to the unique combination of climatic and geographic conditions that exist in the north of…
W1200-7845 was discovered through Disk Detective, a citizen science project funded by NASA and hosted by Zooniverse that provides images of objects in space for the public to classify, with the aim of picking out objects that are likely stars with disks that could potentially host planets. Citizen scientists can look through ‘flipbooks’ —images of…
Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are these stars plagued by magnetic spots, some also experience superflare events, explosions of energy several million times more energetic than similar eruptions on the Sun. The findings, published today in…
Pasadena, CA— The universe is full of billions of galaxies—but their distribution across space is far from uniform. Why do we see so much structure in the universe today and how did it all form and grow? A 10-year survey of tens of thousands of galaxies made using the Magellan Baade Telescope at Carnegie’s Las…
