He has been interviewed on more than 50 Canadian radio stations as well as television across Canada and the US. Kn own as “The Backyard Astronomer”, Gary Boyle is an astronomy educator, guest speaker and monthly columnist for the Royal Astronomical Society of Canada as well as past president o f the Ottawa Centre of the RASC.

And that smudge to Cassiopeia’s right is the Andromeda Galaxy.Īt two and a quarter million light-years away it is the closest galaxy to us. On a clear moonless night, away from light sources, the Double Cluster is seen naked-eye meaning without using any optical aid.Ī few hundred young hot supergiant stars reside in the two clusters. You can find all of our documentation here. The software contained here comes equipped with modules for processing sequencing reads, reconstructing & plotting trees, analyzing these trees, and benchmarking new algorithms. The constellation Perseus is located below the “W”. Cassiopeia is an end-to-end pipeline for single-cell lineage tracing experiments. ![]() You will need binoculars to see this open cluster superimposed in front of the further Milky Way stars.Ī beautiful object located in the constellation Perseus is called the Double Cluster and are two side-by-side star clusters located 7,300 and 7,700 light-years away. The closest exoplanet takes a mere 3 days to orbit the star while the farthest takes 2,220 days.Īside from the individual stars, there is a lovely star cluster with catalogue number M52 located 500 light-years away. One star catalogued HD 219134 located 21 light-years away has seven bodies circling it. To date, 26 exoplanets are orbiting 17 stars. This story depicting six constellations is sometimes referred to as the “Royal Family of Constellations.” However, our hero Perseus who was returning from slaying the Medusa rescues Andromeda in the nick of time as they ride off on his winged horse Pegasus. Legend states that the sea god Poseidon was not pleased with Cassiopeia’s statement of her vanity and forced the King and Queen to sacrifice their daughter Andromeda to the sea monster Cetus. She often boasted that she was the most beautiful of all. In Greek mythology, King Cephus and Queen Cassiopeia ruled the land.

There’s another brilliant star in Cassiopeia as well, but you can’t see it there from here.The Backyard Astronomer, Gary Boyle. Its remnant dust cloud and X-rays are well known to modern astronomers. It was first seen in November 1572 and gradually faded from view in 1574. 16, when it was about magnitude -4 and visible in daylight. ![]() It is often referred to as “Tycho’s Supernova.” The peak was on Nov. The powerful supernova was tracked by the famed Danish astronomer Tycho Brahe. The classic “M” (or “W”) of Cassiopeia was thrown right off in 1572 when a brilliant star appeared close by. The star, however, was a major navigational beacon during the early space missions, and was nicknamed by the Mercury astronaut Vigil Ivan “Gus” Grissom as “Navi,” which was his middle name spelled backwards. Most prominent, naked-eye stars carry an ancient Arabic or Latin name. Gamma Cassiopeia sadly lacks another name. Shining steady at +3.34, this blue-white star is around 440 light years away. The last star of the “M” is Segin, or Epsilon Cassiopeia. ![]()
