A Guide to the April 15, 2014 Total Lunar Eclipse

A Guide to the April 15, 2014 Total Lunar Eclipse

: By Dave Huestis
On April 15, stargazers here in Southern New England will have an opportunity to observe a total lunar eclipse. Though the Moon will set before the eclipse completes, we will be able to watch this celestial event from the beginning until just after the outgoing partial phase ends.

Ghost of Jupiter: NGC 3242

: By Glenn Chaple
This planetary nebula gets its nickname “Jupiter’s Ghost” because its angular size and slightly oval shape (40” by 35”) approximate those of its namesake planet. Make Jupiter 10 magnitudes fainter and change its color from lively yellow to pale blue-green, and you have NGC 3242 – Jupiter’s Ghost!

M46 & NGC 2438

M46 & NGC 2438

: By Glenn Chaple
There’s a saying that goes, “You can’t see the forest for the trees.” In the case of the planetary nebula NGC 2438, “you can’t see the nebula for the stars.” NGC 2438 lies within the northern portion of the open cluster Messier 46 and is often overshadowed by the surrounding stars.

Kemble's Cascade & NGC 1502

: By Glenn Chaple
In 1980, while scanning a rather vacant area of the constellation Camelopardalis with 7 X 35 binoculars, Canadian amateur astronomer Fr. Lucian J. Kemble came across “a beautiful cascade of faint stars tumbling from the northwest down to the open cluster NGC 1502.”
John Dobson (1915-2014)

John Dobson (1915-2014)

: By Francine Jackson
John Dobson, known for popularizing astronomy through his Sidewalk Astronomy style of outreach (and the founder of the San Francisco-based Sidewalk Astronomers) passed away on January 15, 2014 at age 98. Dobson was perhaps best known for the simple rocker-box style of telescope mounting that bears his name, but his decades-long commitment to bring astronomy to the public is perhaps even more significant, and as such should be a role model for all of us to share our love for the night sky.
University of Rhode Island Planetarium

University of Rhode Island Planetarium

: By Francine Jackson
Nestled quietly on the corner of Upper College Road and Engineering Row is a unique little building resembling a silo stepped on by the Jolly Green Giant. Many students who pass by this building have no idea they are looking at one of the most modern planetariums in the area. The University of Rhode Island Planetarium, a part of the campus for decades, has within its doors the ability to travel through the solar system, and beyond.
