Solar Upheaval1083 viewsThe last few weeks have seen the emergence of several large sunspots as solar maximum peaks. Active Region 1967 is wider than the planet Jupiter and its primary dark cores are big enough to swallow Earth many times over. This image was taken in Calcium-K (393.4 nm) from Alamogordo, NM using a 90mm refractor at f20, and Lunt B1200 Cak module and Imaging Source 41AU02 camera.

IC 1275 region1496 viewsIC (Index Catalog) 1275 is an emission nebula located within a rich star field in the constellation Sagittarius. The red color is due to ionized hydrogen gas (HII regions) being excited by nearby stars. Image taken through a Borg 71FL and modified Canon XS DSLR (two hour exposure, stacked with Nebulosity and processed in Photoshop).

The Red Rose1439 viewsSh2-275 is also known as the Rosette nebula and is a star forming region in the winter sky. Ionized hydrogen gas gives it a red color. The Rosette is about four times the size of the full Moon and is approximately 5200 light years away and about 130 light years in diameter. Open cluster NGC 2244 is located near the center of the nebula. Taken with an Orion 100ED f/9 telescope and modified Canon 1000D camera, 60 min exposure.

Crater Copernicus1134 viewsCopernicus is a 93 km (57.7 miles) wide crater located in eastern Oceanus Procellarum. It is estimated to be about 800 million years old and is nearly 3.8 km (2.35 miles) deep (over twice as deep as the Grand Canyon!). Image taken using a 6" SCT at f20 using an Imaging Source DMK41AU02 camera.

The Ringed Planet1339 viewsSaturn is the 6th planet from the Sun at a distance of about 900 million miles. The rings are composed primarily of water ice with particles the size of snowflakes up to house-sized boulders. The rings extend almost 50,000 miles above the planet and average about 60 feet thick (paper thin indeed). To learn more about Saturn, go to our "PLANETS" page. Celestron C9.25 at f25, Imaging Source 21AU618 color camera.

The Owl Nebula1242 viewsThe Owl Nebula (Messier 97, or M97) is a planetary nebula in the Big Dipper about 2600 light years away. The nebula formed about 6,000 years ago when a Sun-like star died. The nebula gets its name from the owl-like "eyes". This narrowband image consists Hydrogen alpha, Hydrogen beta and Oxygen emission lines captured through a 120mm f/8.3 refractor and Atik 314L+ camera (109 min total exposure).

Yerkes Observatory1151 viewsYerkes Observatory was established in 1897 in Williams Bay, Wisconsin and is considered the birthplace of modern astrophysics. The observatory is operated by the University of Chicago and houses a 40 inch Alvin Clark & Sons refractor telescope. The telescope remains the largest refractor in the world.

Space Shuttle Endeavour1070 viewsTook a tour of the Endeavour exhibit in Los Angeles, CA. For more images of the shuttle, check out our AAG Facebook photo album. Endeavour flew to the Hubble Space Telescope on servicing missions and to the International Space Station and installed the Alpha Magnetic Spectrometer.

The King of the Planets1242 viewsJupiter is visible in the early morning almost directly overhead in late September/early October. Larger than all the other planets combined, its only 1/1000th the mass of the Sun. The bands visible in the atmosphere are due to upwelling compounds whose exact nature is not quite known. Ultraviolet light from the Sun caused the compounds brown, orange and other colors. Imaged taken using a 5" SCT at f25 (~3750mm) using an Imaging Source 21AU618 color camera (1/45 sec exp, 3316 fr cap/2875 stacked /90% qual)

Who Needed ISON?1114 viewsWhile Comet ISON evaporated while going around the Sun, Comet Lovejoy (C2013 R1) is putting on a show in our morning sky. It is visible low in the NE before sunrise. This is a 4 min exposure through a 100ED refractor at f7.2 with a modified Canon 1000D at ISO 800. The green color is most likely the result of outgassing of primarily diatomic carbon from solar heating. C2013 R1 was discovered on 9/7/2013 and will make its closest approach to the Sun on 12/22.

A Galactic Rose1218 viewsThe Rosette nebula (Sh2-275) is a large molecular cloud in the constellation Monoceros. The nebula is about 4-6 times the size of the full moon in our night sky. The cloud is mostly comprised of hydrogen gas and is illuminated from the group of hot, young stars near its center. The nebula lies some 5200 light years from the Earth. This image was taken from Alamogordo NM using a 100mm f7.2 refractor and a modified Canon 1000D (XS) DSLR.

Mercury Transit 2016874 viewsThe Mercury transit was well underway when this image was taken at 8:17 AM MT on 5/9/2016 from the AAG outreach event at Imago Dei Academy in Alamogordo, NM. The image was taken using a Stellaruve 80ED refractor with a Lunt B1200 Calcium-K module and Imaging Source 41AU02 camera. The Calcium K-line (393.4 nm) shows supergranulation in the lower chromosphere (~1200 km) along with lighter regions indicating magnetic activity. Sunspot AR2542 along with the small disk of Mercury are also visible.
