150,000 Stars - The Messier 2 Star Cluster

This massive Star Cluster (The Messier 2 Star Cluster) is 13 billion years old - making it one of the oldest star clusters in the Milky Way Galaxy. Not only is this Star Cluster ancient, it is one of the largest known star clusters. On a clear night away from light pollution, you can see M2 with the naked eye as a faint blur in the constellation Aquarius.

These three bright nebulae are often featured in telescopic tours of the constellation Sagittariusand the crowded starfields of the central Milky Way.

In fact, 18th century cosmic touristCharles Messier cataloged two of them; M8, the large nebula left of center, and colorful M20 near the bottom of the frame. The third, NGC 6559, is right of M8, separated from the larger nebula by dark dust lanes. All three are stellar nurseries about five thousand light-years or so distant. The expansive M8, over a hundred light-years across, is also known as the Lagoon Nebula. M20’s popular moniker is the Trifid.

In the composite image, narrowband data records ionized hydrogen, oxygen, and sulfur atoms radiating at visible wavelengths. The mapping of colors and range of brightness used to compose this cosmic still life were inspired by Van Gogh’s famous Sunflowers.

Just right of the Trifid one of Messier’s open star clusters,M21, is also included on the telescopic canvas.

Northern lights over Nyrölä, Finland. My cousin called me last night and said “There’s no clouds over the Central Finland and it’s very dark.”. And so we drove at midnight 30 miles out of the city to get these photographs. It was magical. -Eero

What forms lurk in the mists of the Carina Nebula? The dark ominous figures are actually molecular clouds, knots of molecular gas and dust so thick they have become opaque. In comparison, however, these clouds are typically much less dense than Earth’s atmosphere. Featured here is a detailed image of the core of the Carina Nebula, a part where both dark and colorful clouds of gas and dust are particularly prominent. The image was captured last month from Siding Spring Observatory in Australia. Although the nebula is predominantly composed of hydrogen gas – here colored green, the image was assigned colors so that light emitted by trace amounts of sulfur and oxygen appear red and blue, respectively. The entire Carina Nebula, cataloged as NGC 3372, spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.
