En los últimos años, los científicos del consorcio del Telescopio Event Horizon lograron obtener imágenes no sólo de uno, sino de dos agujeros negros supermasivos utilizando una técnica conocida como interferometría de muy larga base. Sin embargo, lograrlo no es para nada simple, y los futuros descubrimientos van a requerir más potencia aún. Para lograrlo, un telescopio del Observatorio Nacional Kitt Peak se suma a esta misión.

In the past few years, scientists with the Event Horizon Telescope consortium have managed to successfully image not just one, but two supermassive black holes using a technique known as Very Long Baseline Interferometry. Doing so, however, is not a proverbial walk in the cosmic park, and future targets of discovery need even more power. To assist in this mission, a telescope at Kitt Peak National Observatory has also joined the fray.

The first stars illuminated the Universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos.

When scientists detected the gamma-ray burst known as GRB 221009A on October 9, 2022, they dubbed it the BOAT, or the brightest-of-all-time. Now, scientists studying GRB 221009A describe an unusual structure to the jet of material expelled during the explosion that may explain GRB 221009A’s extreme nature and why its afterglow remained visible for so long after the event.

Gemini Norte, que forma parte del Observatorio Internacional Gemini, y que opera NOIRLab de NSF, está de regreso observando el cielo nocturno, luego de la reparación y renovación de su espejo primario. La primera observación del telescopio capturó la supernova llamada SN 2023ixf, que fue descubierta el pasado 19 de mayo por el astrónomo japonés Koichi Itagaki. Este deslumbrante descubrimiento, la supernova más cercana vista en los últimos cinco años, se encuentra en uno de los brazos espirales de la Galaxia del Molinete (Messier 101).

Gemini North, part of the International Gemini Observatory operated by NSF’s NOIRLab, is back observing the night sky following the repair and refurbishment of its primary mirror. The telescope’s debut observation captured the supernova dubbed SN 2023ixf, which was discovered on 19 May by Japanese astronomer Koichi Itagaki. This dazzling point of light, the closest supernova seen in the past five years, is located along one of the spiral arms of the Pinwheel Galaxy (Messier 101).

While studying classical novae using the National Radio Astronomy Observatory’s Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations, which detected non-thermal emission from a classical nova with a dwarf companion, were presented today at a press conference during the 242nd proceedings of the American Astronomical Society in Albuquerque, New Mexico.

Tras estudiar estrellas novas clásicas con el Long Baseline Array (VLBA) del Observatorio Radioastronómico Nacional de Estados Unidos, una estudiante de posgrado descubrió pistas de que estos objetos no son tan simples como se creía. Las nuevas observaciones, en las que se detectaron emisiones no térmicas de una nova clásica con un objeto compañero enano, se presentaron hoy durante la 242 asamblea de la Sociedad Astronómica de Estados Unidos, celebrada en Albuquerque (Nuevo México).

Our familiar, warm, yellow sun is a relative rarity in the Milky Way. By far the most common stars are considerably smaller and cooler, sporting just half the mass of our sun at most. Billions of planets orbit these common dwarf stars in our galaxy.

A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique – the mass of a galaxy containing a quasar, as well as their evolution in cosmic time.

Artificial satellites photobomb about 10% of Hubble exposures on celestial targets. But a typical satellite trail is very thin and will affect less than 0.5% of a single Hubble exposure. Astronomers have developed tools for cleaning the images and improving the quality of Hubble science observations.

With its large, light-gathering mirror and infrared sensitivity, NASA’s James Webb Space Telescope (JWST) is uniquely suited to study galaxies that existed in the early universe, just a few hundred million years after the big bang. Just over one whole month of Webb’s observing time is devoted to the JWST Advanced Deep Extragalactic Survey, or JADES. JADES will peer deeply into the universe to study some of the faintest and most distant galaxies. Among the program’s first findings: Hundreds of galaxies that existed when the universe was less than 600 million years old, and galaxies that have undergone repeated bursts of star formation.

The digital age has been a tremendous boon to the fields of both statistics and astronomy. However, according to Dr. Max Bonamente, a professor of physics and astronomy at The University of Alabama in Huntsville (UAH), most astronomers are not sufficiently trained to realize the substantial benefits to be gained by putting these disciplines together.
