Cosmic Challenge: The Deer Lick Group

Oct 01 2019 05:03 AM | PhilH in Phil Harrington's Cosmic Challenge

The autumn sky abounds with little bundles of galaxies scattered throughout its stars. One of the best known is the group of 7 galaxies that surround the magnificent spiral NGC 7331 in Pegasus, the Flying Horse. An observer could easily spend an hour or more just soaking in all that this small patch of sky has to offer.

Cosmic Challenge: Emission Nebula Simeis 57

Sep 01 2019 10:16 AM | PhilH in Phil Harrington's Cosmic Challenge

Simeis 57 is one of the most intriguing emission nebulae in the late summer sky, yet it is almost unknown to visual observers. Photographers, however, know it as a pair of opposing arcs of reddish light, one extending to the north, the other to the south, that appear to be spinning symmetrically away from a common center. Its unusual appearance has led to its two nicknames: the Propeller Nebula or the Garden Sprinkler Nebula.

Cosmic Challenge: Planetary nebula IC 4732

Aug 01 2019 04:55 AM | PhilH in Phil Harrington's Cosmic Challenge

M22 is right in the thick of it, not far from the galactic center of the Milky Way. As such, it has lots of company. One particular planetary nebula proves a worthy adversary through 10- to 14-inch scopes: IC 4732. IC 4732 lies just 1.4° north-northwest of M22. Cataloged at magnitude 12.1, its tiny disk is difficult to pick out from the mob of field stars -- difficult, but not impossible.

Cosmic Challenge: Lunar craters Armstrong, Aldrin, and Collins

Jul 05 2019 11:22 AM | PhilH in Phil Harrington's Cosmic Challenge

Last month, I challenged you to find all six of the Apollo landing sites. This month, to commemorate the 50th anniversary of Neil Armstrong's and Edwin Aldrin's historic landing and moon walk, we return to Mare Tranquilitatis, the scene of Apollo 11, to find three small craters that bear the names of that historic mission's crew members.

Cosmic Challenge: Apollo Landing Sites

May 31 2019 11:46 AM | PhilH in Phil Harrington's Cosmic Challenge

Between July 1969 and December 1972, six teams of United States astronauts ventured across the gap between Earth and Moon to land and walk on that distant world. Have you ever visited their landing sites? If not, let's do so now.
