13 Agosto 2002: Thanks to a unique combination of international cooperation and the latest Internet technology, Gemini Observatory is now well on its way to becoming the world's first global "cyber observatory".

20 Junio 2002: What began as an essay contest in British Columbia, Canada to encourage an interest in astronomy for elementary school students has resulted in spectacular images and scientific data that may warrant possible follow-up observations.

10 Junio 2002: Due to the extremely high fire danger and the possibility of dry lightning strikes, Kitt Peak National Observatory is closing public access to its grounds and the Kitt Peak Visitor Center at 2 p.m. daily instead of the normal 4 p.m. The time change will have an impact on the last guided tour of the day, which will start 30 minutes earlier than normal. The public picnic grounds have already been closed to visitors until further notice.

4 Junio 2002: Optical technicians dressed in clean suits and protective gear incorporate a little old-fashioned "horse sense" into their procedures as they use common horse soap to clean the 8-meter (26-foot) mirror of Gemini North Telescope high atop the nearly 14,000-foot (approximately 4,000 meters) peak of Mauna Kea on the Big Island of Hawai'i. The periodic cleaning is a highly complicated process involving more than 500 steps and a crew of more than 20 engineers, technicians and support personnel. The procedure includes dismounting the 24-ton mirror from the telescope structure, lowering it five stories to the basement, mounting it on a washing frame and then washing the aluminum-coated, 20cm (8-inch) thick glass mirror to remove accumulated contaminants on the mirror surface.

3 Junio 2002: Aided by the distorted shape of the stars in normally faint binary systems called Soft X-ray Transients, an astronomer at the University of California-San Diego has determined that two nearby black holes each have a mass no larger than a handful of stars like our Sun.

3 Junio 2002: New observations of the richly populated star cluster NGC 2420 taken by the refurbished WIYN 0.9-meter telescope at Kitt Peak National Observatory suggest that the cluster contains a multitude of clues about the history and evolution of the Milky Way.

21 Mayo 2002: Astronomers using adaptive optics technology on the Gemini North Telescope have observed a brown dwarf orbiting a low-mass star at a distance comparable to just three times the distance between the Earth and Sun. This is the closest separation distance ever found for this type of binary system using direct imaging.

21 Marzo 2002: Astronomers observing with the Gemini North Telescope on Hawaii's Mauna Kea have a powerful new tool to probe mysterious cosmic caldrons like those at the cores of galaxies and stellar nurseries.

25 Febrero 2002: A Canadian-led research team using the Gemini Observatory has released tantalizing evidence that tiny dust particles ejected by hot, massive stars, may survive long enough to reach the interstellar medium. This kind of process might have provided some of the materials necessary for the early formation of planetary systems in the young Universe.

18 Enero 2002: From high atop remote mountains in Chile and Hawaii, the Gemini Observatory gives astronomers access to the entire universe with twin state-of-the-art 8-meter telescopes. Today, Gemini South, the second of the Gemini telescopes to look skyward, was dedicated on its perch on Cerro Pachón in the Chilean Andes.

10 Enero 2002: A new color image of the nearby irregular galaxy NGC 6822 shows a myriad of hot blue massive stars and several famous nebulae in impressive detail.

7 Enero 2002: Astronomers using adaptive optics on the Gemini North and Keck telescopes have taken an image of a brown dwarf orbiting a nearby star similar to the Sun. The faint companion is separated from its parent star by less than the distance between the Sun and the planet Uranus and is the smallest separation brown dwarf companion seen with direct imaging.

7 Enero 2002: Astronomers using the recently commissioned Gemini North telescope in Hawaii have discovered a protoplanetary disk orbiting one of the stars in a newborn quadruple star system. The dusty disk, about three times the size of Pluto's orbit around the Sun, appears nearly edge-on when viewed from Earth.

30 Diciembre 2001:

13 Diciembre 2001: Astronomer Robert A. Schommer, one of the leading members of the scientific staff at the Cerro Tololo Inter-American Observatory in Chile and the director of the U.S. Gemini Program, died in Chile on December 12.

3 Diciembre 2001: On January 18, 2002, the Gemini Observatory will celebrate a significant milestone with the dedication of the Gemini South telescope facility at the summit of Cerro Pachón, Chile. National and international media invitations are still available and journalists can reserve space upon request.

29 Octubre 2001: In the deepest ground-based mid-infrared image ever, the Gemini North Telescope reveals that the mysterious environment around one of the most massive black holes in the Universe is missing a key feature predicted by astronomical theory.

2 Octubre 2001: After seven years of design and construction but only two weeks of commissioning, a remarkable first light image was obtained with a new state-of the-art instrument at the Gemini North Telescope on Hawaii's Mauna Kea. The image of the large galaxy in Pisces called NGC 628 (or Messier 74) has been called the "Perfect Spiral Galaxy" due to its nearly ideal form, which is clearly revealed in this new image.

28 Agosto 2001: Astronomers have discovered a double star system, known as a massive X-ray binary, with an orbit so elongated that the twosome appears to have barely survived the disruptive effects of the supernova that transformed them into a fountain of X-ray energy.

14 Agosto 2001: Astronomers using the National Science Foundation's Blanco Telescope in Chile have used the distorting effects of a weak gravitational lens to discover and locate a dim cluster of at least 15 galaxies at a significant distance from Earth, using only the mass properties of the cluster, not its visible light.
