If confirmed, these findings could fundamentally alter our understanding of the Universe. DES was conducted using the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Victor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab.

Combined with studies of the cosmic microwave background, supernovae, and weak lensing, the analysis hints that dark energy changes over time. Data Release 1, containing data from DESI's survey validation and first year of observations, has now been made available for scientists and the public to explore.

Uno de los planetas encontrados mediante la tecnica de velocidad radial corresponde al exoplaneta menos masivo que se haya descubierto hasta ahora, lo que marca un nuevo punto de referencia para el descubrimiento de planetas mas pequenos alrededor de estrellas cercanas.

One of the planets is the least massive exoplanet ever discovered using the radial velocity technique, indicating a new benchmark for discovering smaller planets around nearby stars.

UU. y operado por NOIRLab de NSF, y el Telescopio Magallanes Baade, los astronomos observaron por primera vez una nova recurrente fuera de la Via Lactea en luz infrarroja cercana. Los datos revelaron emisiones quimicas muy inusuales, asi como tambien una de las temperaturas mas altas jamas registradas para una nova, ambos indicios de una erupcion extremadamente violenta.

Historicamente, este tipo de Jets han permanecido ocultos en el Universo distante. Gracias a estas observaciones, los astronomos disponen de nuevos y valiosos datos sobre cuando se formaron los primeros Jets en el Universo y como influyeron en la evolucion de las galaxias.

This discovery was uniquely enabled by IGRINS's ability to simultaneously detect both metallic and icy chemical signatures, a feat typically accomplished using two different instruments.

Este descubrimiento fue posible gracias a la capacidad de IGRINS para detectar simultaneamente firmas quimicas metalicas y heladas, una hazana que se puede conseguir con dos instrumentos distintos.

Rubin Observatory, funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science, will soon witness the explosions of millions of dying stars. Scientists use the light from these events to measure cosmic distances and study dark energy's effect on the Universe's expansion. Over its 10-year Legacy Survey of Space and Time, Rubin could change our understanding of how -- and when -- the Universe formed. Association of Universities for Research in Astronomy (AURA)
