Kemble's Cascade (NGC1502) , Tyler Eelkema

Kemble's Cascade

Kemble's Cascade's NGC 1502 is located in the Camelopardalis Constellation. It was discovered by Father Lucian J. Kemble. The open star cluster (NGC 1502) contains about forty-five stars. An open star cluster is a group of stars held together by their combined gravitational forces. The stars in an open cluster all formed at the same time, resulting in star that are the same age and distance relative to us. Kemble's Cascade can be seen in the night sky with the chain of stars covering about 2.5 degrees. NGC 1502 is located on the eastern tip of Kemble's Cascade. A pair of good binoculars can see the faint open star cluster at night as it is eight arc minutes in diameter.

This picture of NGC 1502 shows the cluster of stars located in the centre of the photograph. At the very centre of the cluster are two bright (magnitude 7) stars. Many of the stars within the cluster are tinted slightly blue, suggesting they are young high mass stars. Many of the smaller stars are yellow, either being medium sized stars or unrelated. Finally, a large yellow star is located on the right. It could possibly be a high mass super giant that is bringing to transform into a red super gaint.
