RGAS News
Welcome to the Rio Grande Astronomical Society

 Our purpose is to share knowledge and experience, educate people at all levels of astronomical knowledge (especially beginners), hear from expert guest speakers, and support each other in our hobby.

Our Society is open to membership to anyone who is interested in our purpose and activities. We work with other area Societies on a cooperative and absolutely non-competitive basis.

RGAS is in the process of achieving our federal tax-free non-profit status, which we expect to get soon.

  • NASA Successfully Completes First Series Of Ares Engine Tests

    NASA engineers Thursday successfully completed the first series of tests in the early development of the J-2X engine that will power the upper stages of the Ares I and Ares V rockets, key components of NASA's Constellation Program. Ares I will launch the Orion spacecraft that will take astronauts to the International Space Station and then to the moon by 2020. The Ares V will carry cargo and components into orbit for trips to the moon and later to Mars.

  • Swedish Space Gym Being Tested By Astronauts

    The crew of the International Space Station (ISS) is presently testing a Swedish space gym. The aim is to counteract muscle atrophy and osteoporosis in astronauts. Astronauts who spend a long time in space can face problems when they return to earth. Weightlessness atrophies the muscles and decalcifies the skeleton. It doesn't help to "pump iron." Barbells and dumbbells are also weightless on a space voyage.

  • Merging Antennae Galaxies Move Closer

    New research on the Antennae Galaxies shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought -- 45 million light-years instead of 65 million light-years.

  • GIOVE-B Transmitting Its First Signals

    Following a successful launch on April 27, GIOVE-B began transmitting navigation signals May 7. This is a truly historic step for satellite navigation since GIOVE-B is now, for the first time, transmitting the GPS-Galileo common signal using a specific optimised waveform, MBOC (multiplexed binary offset carrier), in accordance with the agreement drawn up in July 2007 by the EU and the US for their respective systems, Galileo and the future GPS III.

  • Iron 'Snow' Helps Maintain Mercury's Magnetic Field, Scientists Say

    New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground. The movement of this iron snow could be responsible for Mercury's mysterious magnetic field.

  • Exhaling For Exploration: Scientists Test Lunar Breathing System

    Imagine yourself hip-to-hip, shoulder-to-shoulder, inside a room the size of a walk-in closet for eight hours with five people you just met. Does that make you sweat? Or maybe make your breathing a little more animated? For three weeks, 23 volunteers dedicated time to do just that -- sweat and breathe -- inside a test chamber so NASA scientists at Johnson Space Center in Houston could measure the amount of moisture and carbon dioxide absorbed by a new system being developed for future space vehicles. The system is designed to control carbon dioxide and humidity inside a crew capsule to...

  • Part Of Universe's Missing Matter Discovered By XMM-Newton X-Ray Observatory

    ESA's orbiting X-ray observatory XMM-Newton has been used by a team of international astronomers to uncover part of the missing matter in the universe. Ten years ago, scientists predicted that about half of the missing 'ordinary' or normal matter made of atoms exists in the form of low-density gas, filling vast spaces between galaxies. But the low density of the gas hampered many attempts to detect it in the past. With XMM-Newton's high sensitivity, astronomers have discovered its hottest parts.

  • Record-Setting Laser May Boost Search For Earthlike Planets 100 Fold

    Scientists have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. They also have shown that this type of laser, when used as a frequency comb -- an ultraprecise technique for measuring different colors of light -- could boost the sensitivity of astronomical tools searching for other Earthlike planets as much as 100 fold.

  • Solar Images Show Green And Blue Flashes

    The Earth's atmosphere is a gigantic prism that disperses sunlight. In the most ideal atmospheric conditions, such as those found regularly above Cerro Paranal, this will lead to the appearance of so-called green and blue flashes at sunset. The phenomenon is so popular on the site that it is now the tradition for the Paranal staff to gather daily on the telescope platform to observe the sunset and its possible green flash before starting their long night of observations.

  • Plan To Send A Probe To The Sun

    NASA has a new plan to send a spacecraft closer to the sun than any probe has ever gone. The ambitious Solar Probe mission will study the streams of charged particles the sun hurls into space from a vantage point within the sun's corona -- its outer atmosphere -- where the processes that heat the corona and produce solar wind occur. At closest approach Solar Probe would zip past the sun at 125 miles per second, protected by a carbon-composite heat shield that must withstand up to 2,600 degrees Fahrenheit and survive blasts of radiation and energized dust at levels...
