Realm of the Galaxies (From Camberwell) – 21st February 2015

Latest batch of captures from the orange skies of Camberwell. A very rewarding session last night with unusually good skies.

The main objective of the evening was to attempt to see some of the more distant galaxy clusters from my home location.

So these are up first. Whilst feint and fuzzy, just being able to see such distant galaxy clusters from my backyard has been a long time aim and to be able to see these at all from the polluted skies of London is very satisfying indeed.

First up: Abell 1367 The Leo Cluster – Part of the Great Wall – A distance of 280 Million Light Years. Other than 6 or 7 bright stars in the image below, all other items are Galaxies, each not dissimilar to our own Milky Way.

The Milky Way (and our local group of galaxies) is heading towards the Great Wall drawn by the gravitational pull of the Great Attractor, a localised concentration of an unimaginable quantum of mass which resides further distant still, at a break neck speed of 22,000,000 KM/Hour but we will never reach it because the fabric of space is expanding by a similar amount due to the measured expansion of the Universe or ‘Dark Flow’, discovered by Edwin Hubble.

Second: Copelands Septet or Hickson 57. A group of 8no interacting, possibly merging galaxies, also in the constellation of Leo. (upper right of centre in the capture below). This cluster is at a staggering distance of 480 Million Light Years which means that the light photons observed last night had been travelling the equivalent to 3.5% of the age of the Universe to reach my telescope/camera last night.

Third: Abell 1656, also part of the Great Wall. This cluster, along with the Leo Cluster above is part of a Super Cluster known as the Coma Super Cluster with some 1000+ identified Galaxy members. Abell 1656 is some 320 Million Light Years away in the Constellation of Coma Berenices.

Finally: NGC3158 and region – Galaxy Cluster in Leo Minor some 275 Million Light Years away.

On to a few other objects a little closer to home:

Below is a fantastic example of an edge on spiral galaxy – NGC4565. This one is known as the Needle Galaxy and from end to end is approximately 130,000 Light Years in length. NGC4565 has a very bright nuclei and the dark dust lane is also clearly evident in its disc. The Needle Galaxy is in the constellation of Coma Berenices and is between 30-50 Million Light Years away.

Next up is M81 – Bodes Galaxy. This is a popular target and lies in the Constellation of Ursa Major and is a mere 12 Million Light Years distant. M81 is also a spiral galaxy and lies at an inclined angle to our vantage point. It has an active galactic nuclei that is believed to contain a 70 Million Solar Mass black hole.   Its spiral arms can be made out in the image below.

Third: Another favourite, The Whirlpool Galaxy M51 – A face on Spiral interacting with the adjacent smaller galaxy. In the Constellation of Canes Venatici. At a distance of approximately 25 Million Light Years.

Closer to home still. Below is a selection of other objects located within our own Galaxy system the Milky Way which were also captured during last nights observing session:

The Owl Nebula / M97 – A Planetary Nebula. Again in Ursa Major some 2100 Light Years away. M97 is thought to be only 8000 years old and was formed from an outfall of gas including Hydrogen, Helium, Nitrogen and Oxygen when an aging star began to run out of fuel and has shed its outer layers. At its centre resides a White Dwarf.

Below is another favourite – IC434, The Horsehead is a Dark Nebula, some 1500 Light Years away in the Constellation of Orion.

Below is Globular Cluster M3. Made up of some 500,000 stars and thought to be over 8 Billion Years old and one of the best examples of this type of object in the Northern Hemisphere. M3 is approximately 34,000 Light Years away.

Sunday observing session between the clouds

Results of a very brief observing session this evening between tea and the clouds rolling in here in London.

More magnification than last week with a larger telescope and also using a UHC filter to improve contrast.

First up is M42 The Great Orion Nebula, the nearest star forming region with reflection, emission and dark nebula all evident.

Next up is M82 in Ursa Major with supernova 2014. M82 is a starburst galaxy 12 million light years away in Ursa Major (The Plough). The 2014 type 1a supernova can be clearly seen in the upper side of the galaxy. M82 is apparently 5 times more luminous than the Milky Way.

Next is an edge on spiral galaxy in the Lynx constellation called NGC 2683. Just visible as a slender fuzzy strip but with a particularly bright core. Discovered by William Herschel in 1788, and often referred to as the UFO galaxy it is located about 20million light years away and receding from us at about 400km/second.

Lastly but not particularly visually impressive but rewarding to find none the less is the globular cluster called NGC 2419, the ‘Intergalactic Wanderer’, again in the Lynx constellation (the fuzzy grey blob in the centre of the image below). This object is a gravitationally bound group of up to 1 million stars that orbits the Milky way at a great distance of some 300,000 light years and is one of the most distant globular clusters in our galaxy. It orbits the centre of the galaxy only once every 3 billion years or so. It was also discovered by William Herschel in 1788.

Tucanae 47

Tucane 47

Image Credit: ESO

An infrared image of the globular cluster Tucanae 47 otherwise known as NGC 104 located in the constellation of Tucana.

The image was taken by the VISTA telescope located at ESO Paranal Observatory in Chile.

The second brightest globular cluster in the sky, Tuc 47 is visible with the naked eye but unfortunately only from the southern hemisphere.

Tucanae 47 contains over a million stars and is aproximately 120 light years across and is located about 15,000 light years from Earth.

Home to many types of exotic stars including binary stars, neutron stars and a large number of millisecond pulsars, Tuc 47 has an approximate age of over 13 billion years.
