Look to the east of mighty Orion and you’ll see the constellation Monoceros, the Unicorn. While its stars are faint, Monoceros holds a small treasure chest of superb deep-sky sights for backyard stargazers. Perhaps the most striking is the Rosette Nebula, an achingly beautiful blossom of glowing gas and dust where new stars are forming. The Rosette is an immense nebula, some three times larger than the Orion Nebula and three times farther away. As you see in the image above by Terry Hancock, the nebula overlaps the star cluster NGC 2244 which has formed within the nebula and blown a bubble to give us a look inside. While hard to see the Rosette visually, even in large telescopes, the nebula is an excellent photographic target and the cluster is a superb sight [Read more…] about The Rosette NebulaShare This:

I write this in late October. Every night, the sky is four minutes more wintry than it was the night before. For now, the sky is still dominated by the constellations most associated with Autumn, even as the Summer Triangle slides past the meridian and the Pleiades rise in the east.
The constellations of northern autumn, Pegasus and Andromeda, linger well into the winter months and offer many deep sky wonders for observers equipped with a good telescope. One recent autumn evening, as the Pleiades rose in the east, I set about looking for a handful of these sights in my 8-inch Edge HD Schmidt-Cassegrain telescope [Read more…] about Faint Fuzzies in and Around Pegasus and AndromedaShare This:
Let’s follow last week’s sky tour with a pair of objects where low power is so essential that without it, you might miss them entirely. The first is the open cluster IC 4665, which lies a degree or two north of the star Beta Ophiuchi (Cebalrai). The cluster was “discovered” by astronomer after astronomer, but it didn’t make enough of an impression on anyone to stick around in the astronomical consciousness until it was finally added to the Index Catalog in 1908. In my little telescope at 18x I see a very scattered group of twenty or so easily seen stars spreading across a degree or more of sky. Try as I might, I could not imagine a compelling picture in this random assortment of star dots. Surrounding the most nearly crowded part of the cluster are a few more isolated pairs and individual stars that give the impression of being cluster members. This might be a better object for binoculars than for any telescope. [Read more…] about A Low-Power Romp in the Late-Summer SkyShare This:
The Rosetta spacecraft made its final maneuver around the Comet Churyumov-Gerasimenko (67p) in 2016 and made a controlled hard landing. Rosetta had accompanied the comet for more than 2 years, measured valuable scientific data, brought a lander on to the comet’s surface and took vast numbers of pictures.
In 2017 the European Space Agency released over 400,000 images from the Rosetta mission. Based on these images, motion designer Christian Stangl and composer Wolfgang Stangl worked together to create this short (but quite astonishing) film.
The sequences are digitally enhanced real-footage from the probe.
