11 Noviembre 2015: A new book will give readers a behind-the-scenes look at how spectacular images of space are made by the world’s largest and most powerful telescopes. The telescopes and images of National Optical Astronomy Observatory (NOAO) and Gemini Observatory are showcased in this book by long-time observer Dr. Travis Rector.

12 Octubre 2015: A team led by the California Institute of Technology has been selected to transform the venerable 2.1 meter telescope at Kitt Peak National Observatory into the first dedicated adaptive optics (AO) observatory for astronomy. This system, named Robo-AO KP, will allow astronomers to study, at high angular resolution, large numbers of astronomical objects, spanning science from planetary to stellar, and exoplanetary to extragalactic.

25 Septiembre 2015: A new Gemini Observatory image reveals the remarkable “fireworks” that accompany the birth of stars. The image captures in unprecedented clarity the fascinating structures of a gas jet complex emanating from a stellar nursery at supersonic speeds. The striking new image hints at the dynamic (and messy) process of star birth. Researchers believe they have also found a collection of runaway (orphan) stars that result from all this activity..

21 Septiembre 2015: The Dark Energy Spectroscopic Instrument (DESI), destined for the 4-meter Mayall telescope at Kitt Peak National Observatory (KPNO), will chart out the role of dark energy in the expansion history of the universe. The US Department of Energy has announced its approval of Critical Decision 2 (CD-2) for the DESI project, authorizing its scientific scope, schedule, and funding profile. The Mayall telescope is operated by the National Optical Astronomy Observatory (NOAO).

14 Septiembre 2015: A team of astronomers has given us our best view yet of an exoplanet moving in its orbit around a distant star. A series of images captured between November 2013 to April 2015 shows the exoplanet β Pic b as it moves through 1 ½ years of its 22-year orbital period.

10 Septiembre 2015: Continuing Gemini Observatory’s commitment to the positive stewardship of our planet, Gemini leads in the use of renewable energy sources on Maunakea.

13 Agosto 2015: Going beyond the discovery and imaging of a young Jupiter, astronomers using the Gemini Observatory's new Planet Imager (GPI) have probed a newly discovered world in unprecedented detail. What they found is a planet about two times the mass of Jupiter, and the most Solar System-like planet ever directly imaged around another star.

9 Agosto 2015: Honolulu, Hawai (9 de agosto de 2015) - Hoy, en la reunión de la Unión Astronómica Internacional (IAU), la Asociación Internacional de Cielos Oscuros (IDA) anunció que el sitio del Observatorio de la Asociación de Universidades para la Investigación en Astronomía (AURA) en el Valle de Elqui en el norte de Chile será reconocido y designado como el primer Santuario Internacional de Cielos Oscuros en el mundo. El sitio se conocerá como el "Santuario de Cielos Oscuros Gabriela Mistral” en honor a la reconocida poeta chilena.

27 Julio 2015: Two undergraduates at San José State University have discovered two galaxies that are the densest known. Similar to ordinary globular star clusters but a hundred to a thousand times brighter, the new systems have properties intermediate in size and luminosity between galaxies and star clusters.

9 Julio 2015: NOAO scientists, using the Gemini Observatory 8-meter telescope in Chile, have obtained the highest resolution image ever obtained for the planetary nebula NGC 2346. Shaped like a butterfly, or an hourglass, but known scientifically as a bipolar planetary nebula, this object is at a distance of 2,300 light-years from our Sun in the constellation Monoceros.

15 Junio 2015: Using the advanced adaptive optics system GeMS, on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box – a tightly packed cluster of stars that is one of the few places in our galaxy where astronomers think stars can actually collide.

14 Abril 2015: A new ground-based telescope promises unprecedented information about distant galaxies, nearby asteroids and even the mysterious dark energy that is accelerating the expansion of our universe.

3 Marzo 2015: Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way’s “suburbs.” It is located where astronomers have never spotted such a small cluster of stars before.

9 Febrero 2015: Kitt Peak National Observatory is the future home of a state-of-the-art instrument that will be used to detect and characterize other worlds. The new instrument, an extreme precision radial velocity spectrometer, will measure the subtle motion of stars produced by their orbiting planets. The spectrometer, funded by NASA, will be deployed on an existing telescope at Kitt Peak, the 3.5-meter WIYN telescope. The National Optical Astronomy Observatory (NOAO), which is funded by NSF, is a partner in the telescope and operates Kitt Peak.

6 Enero 2015: Stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI) were featured today in a press conference at the 225th meeting of the American Astronomical Society (AAS) in Seattle, Washington. The Gemini Planet Imager GPI is an advanced instrument designed to observe the environments close to bright stars to detect and study Jupiter-like exoplanets (planets around other stars) and see protostellar material (disk, rings) that might be lurking next to the star.

5 Enero 2015: The Magellanic Clouds are the two brightest nearby satellite galaxies to our own Milky Way galaxy. From a new study it appears that not only are they much bigger than astronomers calculated, but also have non-uniform structure at their outer edge, hinting at a rich and complex field of debris left over from their formation and interaction. This is an early result from a survey called SMASH, for “Survey of the MAgellanic Stellar History”, carried out by an international team of astronomers using telescopes that include the Blanco 4-meter at Cerro Tololo Inter-American Observatory (CTIO) in Chile and presented today at the 225th meeting of the American Astronomical Society in Seattle, Washington.

18 Diciembre 2014: Galaxies – spirals laced with nests of recent star formation, quiescent ellipticals composed mainly of old red stars, and numerous faint dwarfs – are the basic visible building blocks of the Universe. Galaxies are rarely found in isolation, but rather in sparse groups – sort of galactic urban sprawl. But there are occasional dense concentrations, often found in the center of giant clusters, but also, intriguingly, as more isolated compact groups (and yes, called Compact Galaxy Groups or CGs). The galaxies in these Compact Groups show dramatic differences in the way they evolve and change with time compared with galaxies in more isolated surroundings. Why is this? Collisions between galaxies in these dense groups are common, leading to rapid star formation, but there seems to be more to the puzzle.

7 Noviembre 2014: Astronomers are announcing today the discovery of two unusual objects in comet-like orbits that originate in the Oort cloud but with almost no activity, giving scientists a first look at their surfaces. These results, presented today at the annual meeting of the Division of Planetary Sciences of the American Astronomical Society in Tucson, Arizona, are particularly intriguing because the surfaces are different from what astronomers expected, and they give us clues about the movement of material in the early solar system as the planets were assembled.

22 Septiembre 2014: Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This may help explain why some T Tauri stars have disks that glow weirdly in infrared light while others shine in a more expected fashion.

16 Septiembre 2014: A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. The finding suggests huge black holes may be more common than previously believed.
