Coleynotes Naked Eye Dark Sky Update

Dark Night Black Hole

Feeling Cosmic?

The Theory of a Black Hole in the Milky Way or /and the Universe is not explained properly or very good in this...but still better than Creationism theory..

A short film about Black holes..

You tube video on massive black holes.

The Story Behind Metal Postcard


The title "Mittageisen" is a word play based on the German words "Mittagessen" (literally: "noon meal", i.e. lunch) and Eisen ("iron"). The title was inspired by John Heartfield's 

photocollage Hurrah, die Butter ist Alle! ("Hurray, the Butter is Finished!"), which was also used as the single's cover art.

Heartfield's photocollage was initially used on the front page of the Arbeiter-Illustrierte-Zeitung (Workers Illustrated Journal), published on 19 December 1935. Heartfield (1891–

1968) was an early member of Club Dada, which started in 1916 as Cabaret Voltaire in Zürich. The picture with the title 'Hurrah, die Butter ist Alle! / Hurray, the butter is finished!' 

shows a family who eats various pieces of metal. The trigger for it was the following quote from Hermann Göring: "Iron always made a nation strong, butter and lard only made the 

people fat".

Cabaret Voltaire was the name of a nightclub in Zurich, Switzerland. It was founded by Hugo Ball, with his companion Emmy Hennings on February 1, 1916 as a cabaret for
artistic and political purposes. Other founding members were Marcel Janco, Richard Huelsenbeck, Tristan Tzara, and Sophie Taeuber-Arp and Jean Arp. Events at the cabaret proved pivotal in the founding of the anarchic art movement known as Dada.

Bigging up band the June Brides - drop this name into - every conversation

8 million stories 

Have just been listening to....

The June Brides.... an English indie pop group, formed in London in 1983, by Phil Wilson and Simon Beesley of International Rescue. Influenced by Postcard-label bands such as Josef K and punk-era bands such as Buzzcocks, The Desperate Bicycles and The Television Personalities, their mix of guitar pop with viola and trumpet formed a blueprint for many of the indie pop bands that would follow.

Aurora lights danced as far as midlands for a naked eye view in march 2015

Naked Eye View of Aurora in UK aurora uk

Tuesday night was a busy one for the Beeb - see the pictures of aurora on the site tonight.

Most auroras occur in a band known as the auroral zone, which is typically 3° to 6° wide in latitude and between 10° and 20° from the geomagnetic poles at all local times (or longitudes), most clearly seen at night against a dark sky. A region that currently displays an aurora is called the auroral oval, a band displaced towards the nightside of the Earth. Day-to-day positions of the auroral ovals are posted on the internet. A geomagnetic storm causes the auroral ovals (north and south) to expand, and bring the aurora to lower latitudes. Early evidence for a geomagnetic connection comes from the statistics of auroral observations. Elias Loomis (1860) and later in more detail Hermann Fritz (1881) and S. Tromholt (1882) established that the aurora appeared mainly in the "auroral zone", a ring-shaped region with a radius of approximately 2500 km around the Earth's magnetic pole. It was hardly ever seen near the geographic pole, which is about 2000 km away from the magnetic pole. The instantaneous distribution of auroras ("auroral oval") is slightly different, being centered about 3–5 degrees nightward of the magnetic pole, so that auroral arcs reach furthest toward the equator when the magnetic pole in question is in between the observer and the Sun. The aurora can be seen best at this time, which is called magnetic midnight.

In northern latitudes, the effect is known as the aurora borealis (or the northern lights), named after the Roman goddess of dawn, Aurora, and the Greek name for the north wind, Boreas, by Galileo in 1619. Auroras seen within the auroral oval may be directly overhead, but from farther away they illuminate the poleward horizon as a greenish glow, or sometimes a faint red, as if the Sun were rising from an unusual direction. Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. It is visible from high southern latitudes in AntarcticaSouth America,New Zealand, and Australia. Auroras also occur on other planets. Similar to the Earth's aurora, they are also visible close to the planets’ magnetic poles. Auroras also occur poleward of the auroral zone as either diffuse patches or arcs, which can be sub-visual.

Astronomy for Geeks and Amateurs

Astronomy is one of the sciences
to which amateurs can contribute the most.

Collectively, amateur astronomers
observe a variety of celestial objects and phenomena sometimes with
that they build themselves
. Common
targets of amateur astronomers include the Moon, planets, stars,
comets, meteor showers, and a variety of
deep-sky objects such as star clusters, galaxies, and nebulae. One
branch of amateur astronomy, amateur
astrophotography, involves the taking of photos of the night sky.
Many amateurs like to specialize in the observation of particular
objects, types
of objects, or types of events which interest them.

Most amateurs work at visible
wavelengths, but a small minority experiment with wavelengths outside
visible spectrum. This includes the use of infrared filters on
telescopes, and also the use of radio telescopes. The pioneer of
amateur radio
astronomy was
Karl Jansky, who started observing the sky at radio
wavelengths in the 1930s. A number of amateur astronomers use either
telescopes or use radio telescopes which were originally built for
research but which are now available to amateurs (e.g. the
One-Mile Telescope).

Amateur astronomers continue to
make scientific contributions to the field of astronomy. Indeed, it is
one of
the few scientific disciplines where amateurs can still make
contributions. Amateurs can make occultation measurements that are used
refine the orbits of minor planets. They can also discover comets, and
regular observations of variable stars. Improvements in digital
technology have
allowed amateurs to make impressive advances in the field of
