Luego de estudiar un poderoso estallido de rayos gamma (GRB por sus siglas en inglés) con el telescopio de Gemini Sur, que opera NOIRLab de NSF y AURA en la Región de Coquimbo, en Chile, un equipo de astrónomos investigan si están ante la presencia de una forma nunca antes vista de destrucción estelar. A diferencia de la mayoría de los GRBs, que son provocados por la explosión de estrellas masivas o por la fusión de estrellas de neutrones, los investigadores concluyen que este particular GRB que observaron desde Chile, fue el resultado de una literal colisión de estrellas o de remanentes estelares en el entorno compacto que rodea a un agujero negro supermasivo en el nucleo de una galaxia muy antigua.
The National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope released eight new images of the Sun, previewing the exciting science underway at the world’s most powerful ground-based solar telescope. The images feature a variety of sunspots and quiet regions of the Sun obtained by the Visible-Broadband Imager (VBI), one of the telescope’s first-generation instruments.
Un instante de la enorme nube interestelar de formación de estrellas Lupus 3, capturado por la Cámara de Energía Oscura de 570-megapíxeles desde el Observatorio de Cerro Tololo de NOIRLab, en Chile. La brillante región central de esta nube en expansión revela un par de jóvenes estrellas brotando desde sus capullos de polvo y gas para iluminar la nebulosa de reflexión conocida como Bernes 149. El contraste de luces entre estas regiones hacen de este objeto uno de los principales lugares para la investigación sobre formación estelar.
Vera C. Rubin Observatory has passed a major construction milestone: the telescope structure is ready to be outfitted with a full-size replica of its 8.4-meter mirror and stand-ins for its 3200-megapixel LSST Camera and other critical optical components. This major milestone means that Rubin Observatory is on track to help probe the mysteries of dark matter, study the fundamental nature of dark energy, document the dynamic Universe, and explore other grand challenges of cosmology.
El Observatorio Vera C. Rubin alcanzó un importante hito en su construcción luego que la estructura del telescopio ya está en condiciones para recibir una réplica exacta de su espejo de 8,4 metros y los componentes para la Cámara LSSTde 3.200 megapíxeles, además de otros dispositivos ópticos críticos. Este importante hito pone al Observatorio Rubin en camino a contribuir con las investigaciones que abordarán los misterios de la materia oscura, la naturaleza de la energía oscura, documentar la dinámica del Universo y explorar otros grandes desafíos de la cosmología.
Janice Lee, Chief Scientist at the International Gemini Observatory, leads the JWST Treasury Survey for the PHANGS (Physics at High Angular resolution in Nearby Galaxies) collaboration to study how star formation affects the evolution of galaxies. These observations are providing new insights into how some of the smallest-scale processes in our Universe — the beginnings of star formation — impact the evolution of the largest objects in our cosmos: galaxies.
Mientras estudiaban los vestigios de una explosión de rayos gamma (GRB por sus siglas en inglés) que fue detectada en 2021, dos equipos de astrónomos hallaron señales sorprendentes de una fusión de estrellas de neutrón, en vez de la esperada huella de una supernova. Las observaciones realizadas desde telescopios terrestres y espaciales, que incluyeron al telescopio de Gemini Sur en Chile y Gemini Norte en Hawai‘i, desafían la teoría prevaleciente que predice que las GRB de este tipo provienen exclusivamente de una supernova, es decir de la explosión final que acaba con la vida de las estrellas masivas.
While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of telescopes in space and on Earth, including the Gemini North telescope on Hawai‘i and the Gemini South telescope in Chile, have uncovered the unexpected hallmarks of a kilonova, the colossal explosion triggered by colliding neutron stars. This discovery challenges the prevailing theory that long GRBs exclusively come from supernovae, the end-of-life explosions of massive stars.
Utilizando la Cámara de Energía Oscura en el Observatorio de Cerro Tololo, en Chile, los astrónomos detectaron tres asteroides cercanos a la Tierra (NEA por sus siglas en inglés) que se ocultaban en el resplandor del Sol. Se trata de una elusiva población de objetos que acechan desde el interior de las órbitas de la Tierra y Venus. Uno de estos asteroides es el objeto más grande, y potencialmente peligroso para la Tierra, descubierto en los últimos 8 años.
Twilight observations with the US Department of Energy-fabricated Dark Energy Camera at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF's NOIRLab, have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object that is potentially hazardous to Earth to be discovered in the last eight years.
In the early-morning hours of today, 14 October 2022, astronomers using the Gemini South telescope in Chile operated by NSF’s NOIRLab observed the unprecedented aftermath of one of the most powerful explosions ever recorded, Gamma-Ray Burst GRB221009A. This record-shattering event, which was first detected on 9 October 2022 by orbiting X-ray and gamma-ray telescopes, occurred 2.4 billion light-years from Earth and was likely triggered by a supernova explosion giving birth to a black hole.
En las primeras horas de la mañana de hoy, 14 de octubre de 2022, los astrónomos utilizaron el telescopio Gemini Sur en Chile, que opera NOIRLab de NSF y AURA, para observar las consecuencias sin precedentes de una de las explosiones de rayos gamma más poderosas jamás registradas, que fue catalogada como GRB221009A. Este evento récord, que fue detectado por primera vez el 9 de octubre de 2022 por telescopios de rayos X y rayos gamma en órbita, ocurrió a 2.400 millones de años luz de la Tierra y probablemente fue provocado por una explosión de supernova que dio lugar al nacimiento de un agujero negro.
On Wednesday, February 23, 2022, the U.S. National Science Foundation’s (NSF’s) Daniel K. Inouye Solar Telescope (Inouye Solar Telescope) commenced its first science observations, signaling the start of its year-long operations commissioning phase and a new era of solar science. Over 25 years in the making, the world’s most powerful solar telescope is now poised to revolutionize our understanding of the Sun and its impacts on Earth.
Un equipo de astrónomos realizaron las mediciones más precisas hasta el momento del movimiento de las estrellas alrededor del agujero negro supermasivo que se encuentra en el centro de la Vía Láctea, confirmando que el 99,9% de la masa concentrada en el núcleo de la galaxia corresponde a un agujero negro, mientras que sólo un 0,1% podría incluir estrellas, pequeños agujeros negros, polvo y gas interestelar, o materia oscura.
The NSF’s National Solar Observatory, headquartered in Boulder, Colorado, announced the receipt of a prestigious Brinson Prize Fellowship from The Brinson Foundation. The award will support a postdoctoral scholar for up to three years starting in the fall of 2022.
Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds.
Recently, NSF's NSO successfully transitioned the processing of these important observations of the Sun’s magnetic field and lower atmosphere to the operational control of NOAA’s Space Weather Prediction Center (SWPC), a move that will ensure reliable delivery of the data to the NOAA’s space weather forecasters who are the nation’s official civilian source for space weather watches, warnings, alerts, and forecasts.
The prefabricated units are designed to be taken completely apart. The walls and roof fold down into two sections. Once disassembled, the houses can be shipped flat with each house fitting on two trailers.
New detailed observations with NSF’s NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet’s existence is at odds with the predictions of leading planet formation theories.
These orange swirls of dust are snapshots from the largest collection of sharp, detailed images of dusty debris disks around young stars — published this week by an international group of astronomers. The images — captured by the 8-meter Gemini South telescope using the Gemini Planet Imager — illustrate the variety of shapes and sizes that stellar systems can take during their infancy. Unexpectedly, the majority of these systems display evidence of planet formation.
Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud color variations.
Barnard’s Galaxy, a dwarf galaxy neighboring the Milky Way, is revealed in this stunning image from the Victor. M. Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory, a program of NSF’s NOIRLab. The image reveals regions of intense star formation and a scattering of immense cosmic bubbles.
Researchers using the Gemini North telescope on Hawaiʻi’s Maunakea have detected the most energetic wind from any quasar ever measured. This outflow, which is travelling at nearly 13% of the speed of light, carries enough energy to dramatically impact star formation across an entire galaxy. The extragalactic tempest lay hidden in plain sight for 15 years before being unveiled by innovative computer modeling and new data from the international Gemini Observatory.
NSF’s National Optical-Infrared Astronomy Research Laboratory, which in 2019 brought together NSF’s optical and infrared nighttime astronomy under one entity, will now go by the shortened name of NSF’s NOIRLab (no-wah-lab), abbreviated from its longer formal name. NOIRLab is headquartered in Tucson, Arizona and operates Kitt Peak National Observatory, the international Gemini Observatory, the Community Science and Data Center, Cerro Tololo Inter-American Observatory, and the operations of the Vera C. Rubin Observatory.
The new NEID instrument, now installed at the 3.5-meter WIYN telescope at Kitt Peak National Observatory in Southern Arizona, USA, has made its first observations. The NSF-NASA funded instrument is designed to measure the motion of nearby stars with extreme precision — roughly three times better than current state-of-the-art instruments — allowing us to detect, determine the mass of, and characterize exoplanets as small as Earth.
Observations with the 8-meter Gemini North telescope, a program of the NSF’s National Optical-Infrared Astronomy Research Laboratory, have allowed astronomers to pinpoint the location of a Fast Radio Burst in a nearby galaxy — making it the closest known example to Earth and only the second repeating burst source to have its location pinpointed in the sky. The source of this burst of radio waves is located in an environment radically different from that seen in previous studies. This discovery challenges researchers’ assumptions on the origin of these already enigmatic extragalactic events.
On 1 October 2019, the nighttime astronomy facilities supported by the National Science Foundation (NSF) transitioned to operating as one organization, NSF's National Optical-Infrared Astronomy Research Laboratory. The new organization operates five scientific programs: Cerro Tololo Inter-American Observatory, the Community Science and Data Center, Kitt Peak National Observatory (all formerly known as the National Optical Astronomy Observatory); Gemini Observatory and the upcoming Large Synoptic Survey Telescope, and is managed by the Association of Universities for Research in Astronomy.
On July 2, 2019 a total solar eclipse will pass over Chile and Argentina, and through a stroke of astronomical luck, the path of totality crosses directly over the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory located in the foothills of the Andes, 7,241 feet (2200 meters) above sea level in the Coquimbo Region of northern Chile. Five science teams chosen by NSF’s National Solar Observatory will perform experiments at Cerro Tololo during the eclipse; four of them will have their equipment trained on the Sun’s elusive corona and one will study eclipse effects on the Earth itself.
Caught in a cosmic dance, our nearest neighbor galaxies, the Magellanic Clouds, are cartwheeling and circling each other as they fall toward our galaxy, the Milky Way. The gravitational interaction between the Clouds sparks cosmic fireworks—bursts of star formation as new clusters of stars flame on. How many and what kind of star clusters have been born this way over the history of the Clouds? A new project, the Local Group Cluster Search, invites citizen scientists to help find out!
Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy. The remarkably sharp image looks back into the early history of our Universe and sheds new insights on how our Galaxy formed.
