The Large Monolithic Imager

  • NGC 891

    NGC 891 is an edge-on spiral galaxy, located about 10 Mpc (32 million light-years) away. The exposure was unguided and consists of ten 1-min exposures in B, five 1-minute exposures in V, and six 1-minute exposures in R. This was the “first-light” image obtained with LMI obtained on September 12, 2012. The field of view shown is 11.7 arcminutes on a side. Minimal image credit: Massey/Neugent/Dunham/Lowell Obs./NSF

  • The Horsehead Nebula

    The Horsehead Nebula is a dark nebula (dust cloud) that is seen silhouetted against the purplish glowing hydrogen gas that is ionized by the nearby bright star Sigma Ori. The Horsehead is located approximately 460 pc (1500 light-years) away, in the constellation of Orion. The color composite came from three 2-minute exposures in B, three 2-minute exposures in V, and three 2-minute exposures in R, all taken with the new science-grade CCD on March 6, 2013, in 1.2 arcsec seeing.

  • NGC 6946

    NGC 6946 is an Sc type spiral galaxy, rich in young, massive stars and HII regions. The galaxy is seen almost face on, and is located about 6 Mpc (20 million light-years) away. It’s near the galactic plane (b=11.7 deg) and so is highly reddened by foreground dust, with about a magnitude of extinction in the V-band. This image is a color composite generated from twenty 1-min exposures in B, ten 1-min exposures in V, and ten 1-min exposures in R. The images were taken on November 20, 2012, in excellent seeing (0.6-0.7 arcsec). The image shown is 11.0 arcmin on a side. Minimal image credit: Massey/Neugent/Levine/Lowell Obs./NSF

  • M1 (Crab Nebula/NGC 1952)

    The Crab Nebula (Messier 1) is one of the most famous of astronomical objects, the remnant of a supernova that exploded in 1054. The event was recorded by many in that time, include the Japanese, Chinese, Arabs, and native Americans, unsurprisingly as it was so bright that it was visible during the daytime. The Crab was identified as the remnant of the 1054 supernova by early 20th century astronomers, as exposures taken a few years apart revealed that the nebula was expanding. Extrapolating back in time, astronomers realized that the expansion must have begun about 900 years earlier, coincident in
    time with the appearance of the “guest star” in 1054. The Crab Nebula is located about 2 kiloparsecs (6,500 light-years) away in the constellation Taurus. Minimum Image Credit: Massey/Neugent/Lowell Obs./NSF

  • NGC 7293 (Helix Nebula)

    The Helix Nebula is a striking planetary nebula, one of the closest to us. It’s located in the constellation of Aquarius at a distance of 215 parsecs (700 light-years). It’s about 0.8 parsec (2.5 light-years) in diameter. The central star is a hot white dwarf with an effective temperature of 100,000 K, and is responsible for ionizing the surrounding gas causing the beautiful nebulosity. The images were taken by Kathryn Neugent and Phil Massey on October 8, 2013, and the color composite came from ten 100-sec exposures in B, ten 100-sec exposures in V, and ten 60-sec exposures in R.

  • M51 (Whirlpool Galaxy/NGC 5194)

    The Whirlpool Galaxy (M51) and its interacting companion (NGC 5195) are among the most well-known astronomical objects. It’s located about 7.7 Mpc (25 million light-years) away in the constellation of Canes Venatici. The bright blue objects are recently-formed star clusters. This color composite came from seven 1-min exposures in B and R, and five 1-min exposures in V.

  • M104 (Sombrero Galaxy/NGC 4594)

    The Sombrero Galaxy (M104) is a classic edge-on spiral galaxy located about 8.5 Mpc (28 million light-years) away in the constellation of Virgo, and is about 15 Kpc (50,000 light-years) across. This color composite came from seven 1-min exposures in B, V, and R obtained on 27 June 2013. Minimal image credit: Massey/Neugent/Lowell Obs./NSF
