What is the name of the star cluster in the NGC 2264?

Also known as NGC 2264, the Christmas Tree Cluster is an open cluster of stars embedded in a diffuse nebula. This image taken in visible light also contains two famous nebulae. At the bottom center of the image is the Cone Nebula, and to the upper left is the Fox Fur Nebula. When viewed upside-down, the entire cluster looks like a Christmas tree.

Where is the Christmas tree cluster?

Christmas Tree Cluster. The Christmas Tree Cluster is a young open cluster located in the constellation Monoceros. It is part of the NGC 2264 region, along with the Cone Nebula and the Fox Fur Nebula, and belongs to the Monoceros OB1 association, a loose association of very young stars located in the Orion Arm of the Milky Way.

How old are the stars in the OB cluster?

The stars in the cluster were formed very recently from the surrounding molecular cloud. The cluster contains more than 600 members that are 1 to 4 million years old, including several dozen OB stars and more than 400 lower mass members.

Where is NGC 2264?

This colour image of the region known as NGC 2264 — an area of sky that includes the sparkling blue baubles of the Christmas Tree star cluster — was created from data taken through four different filters (B, V, R and H-alpha) with the Wide Field Imager at ESO’s La Silla Observatory, 2400 m high in the Atacama Desert of Chile in the foothills of the Andes. The image shows a region of space about 30 light-years across. Image: ESO

What is Argo Navis named for?

Take Argo Navis, named for the mythological ship that Jason and his compatriots took in search of the Golden Fleece. “Nature did not exactly oblige in giving astronomers a complete set of stars with which to define the ship,” writes the astronomer and author John C. Barentine in The Lost Constellations: A History of Obsolete, Extinct, or Forgotten Star Lore. A handful of stars could credibly form the hull, mast, and other parts, but nothing quite resolved into the prow. To compensate, Barentine continues, “those seeking a figural depiction of Argo were left to come up with ad hoc ways to hide the fact that part of the boat was literally missing.” Cartographers sketching the constellations disguised its absence with a strategically placed atmospheric flourishes—a cloud or a boulder. Halley’s plopped a tree in its place, obviating the need to actually complete Argo Navis.

Where did Edmond Halley set up his observatory?

In 1676, years before he observed the comet that would carry his name, a young astronomer named Edmond Halley set up an observatory on the volcanic island of Saint Helena in the South Atlantic Ocean. From this far-flung speck of land, he intended to catalog the stars of the Southern Hemisphere. Halley returned to England with a slew of observations, in which he eventually included a new constellation, Robur Carolinum, or “Charles’s Oak.” The once-arborially-besieged king had become a patron, and had made Halley’s journey possible.

Back on Earth, an oak still stands on Boscobel’s grounds, and is often described as a descendant of the one where Charles II hid. And another answer was found to the Argo Navis conundrum—it was broken up into a handful of smaller, perhaps more coherent constellations, but the tree did not find its way back in.
