    West Mountain, Moon, Venus, and Stars

    This image was secured just after the end of evening twilight on a clear April night from the West Mountain Observatory. The view is looking west past the domes housing the two smaller research telescopes at the observatory. The thin crescent Moon is also illuminated by reflected light from the Earth that is known as earthshine. Higher in the sky, the bright 'star' is actually the planet Venus. In between the two, the 'V' shaped group of stars in the constellation of Taurus is in reality the nearby open cluster known as the Hyades. Photo credit: Dr. Michael D. Joner

    Total Solar Eclipse: August 21, 2017

    This is a photo secured by Dr. Michael Joner in Riverton, Wyoming of the great eclipse of 2017. The image shows the inner corona along with several solar prominences seen near mid-totality. This is the first solar eclipse visible from the continental United States in 38 years. America's next opportunity will be on April 8, 2024 for viewers between Texas and Maine.

    The Tulip in the Swan

    This image from the BYU 0.9-m telescope looks out along the plane of our Milky Way Galaxy toward the constellation Cygnus the Swan. Called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also listed in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. This nebula is about 8,000 light-years away from the solar system. The nebula shown here is a composite image that maps emission from sulfur, hydrogen, and oxygen atoms into red, green, and blue colors. Energy from the hot O-type star HDE 227018 ionizes atoms in this region so that we see a faint glow from the Tulip Nebula. HDE 227018 is seen near the blue arc at center of the image. This appeared as the NASA Astronomy Picture of the Day on July 26, 2012. Image Credit & Copyright: Michael Joner, David Laney (West Mountain Observatory, BYU); Processing - Robert Gendler

    The BYU 0.9-meter Reflector

    This photograph from university photographer, Mark Philbrick shows the BYU 0.9-meter Reflector at the West Mountain Observatory focused on a field near the galactic center during the summer of 2016. The stars of the constellation Scorpius are visible through the lower center portion of the dome slit with the planets Mars (on the right side) and Saturn (just off the left edge) visible. The computer controlled telescope was funded through an NSF grant; AST 0618209.

    Sunrise Over Plato

    This image of the northern lunar region along the terminator was secured in the early morning hours of 20 August 2018 using the 0.9-meter telescope at the BYU West Mountain Observatory. The dark floored crater catching the sunrise rays is named Plato. This crater is 101 km in diameter and sits on the edge of Mare Imbrium. The mountains running from Plato toward the lower right part of the image are known as the Lunar Alps. The straight feature running about 160 km through the mountains linking Mare Imbrium and Mare Frigoris is known as Vallis Alpes or the Alpine Valley. Image by Dr. Michael Joner.

Astronomy Picture of the Day

Jupiter in Ultraviolet from Hubble : Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant....
