A selection of video captures from recent astronomy antics.
Eskimo Nebula NGC2392 – A Lovely green planetary nebula in the Constellation of Gemini. A medium sized star which is shedding outer layers of gas as it nears the end of its life.
Another shot of Hubble’s variable nebula, see last weeks post for details.
The Flame Nebula NGC 2024 – Clouds of Hydrogen gas illuminated by high energy Ultra Violet light from nearby star Alintak (out of view), the east star in the belt of Orion.
The Horsehead Nebula IC 434, again in Orion. This was taken with a 72mm refractor telescope with a narrow band HA filter to cut out some of light pollution. It is a stack of several 30 second frames.
Bodes Galaxy M81 in Ursa Major, named after Johann Bode who discovered it in 1774. M81 is 12 million Light Years away. The largest member in a cluster of 33 interacting galaxies known as the M81 group. The centre of the galaxy harbours a 70 million solar mass Black Hole! Hard to see but can you make out a spiral arm?
M82 – Again in Ursa Major, a star burst galaxy and in a gravitational tryst with M82 above along with 32 other galaxies in the M81 group . Apparently 5 times more luminous than the Milky Way. Rapid star formation in the last 100million years or so is attributable to the gravitational influence of nearby M81.
The Whirlpool Galaxy M51, Canes Venatici – A face on spiral galaxy discovered by Charles Messier in 1773. Currently interacting with companion galaxy NGC5195. The first to be classified as a Spiral Galaxy. Some 25 Million Light Years away, M51 is approximately 60,000 Light Years across.
The Leo Triplet – Three interacting galaxies located in the Constellation of Leo. Some 35 Million Light Years distant.
For comparison, below is an image from the European Southern observatory of the Leo Triplet:
