Field of diamonds



Field of diamonds in the sky
Worlds are whirling right on by
Are you wondering who am I
Field of diamonds in the sky

Am I just a star in some crown
Or someone's live sun going down, down, down

Field of diamonds in the sky
Silent beauty shining high
Are you tears the angels cry
Field of diamonds in the sky

Field of diamonds in the sky
Like the nihgt you pass me by
I could touch you if I try
Field of diamonds in the sky

Am I just a star in some crown
Or someone's live sun going down, down, down

Field of diamonds in the sky
Silent beauty shining high
Are you tears the angels cry
Field of diamonds in the sky

Black Hole Surfing

The researchers modelled how molecular clouds are sucked into black holes

Astronomers have shed light on how stars can form around a massive black hole, defying conventional wisdom.
Scientists have long wondered how stars develop in such extreme conditions.
Molecular clouds - the normal birth places of stars - would be ripped apart by the immense gravity, a team explains in Science magazine.
But the researchers say stars can form from elliptical discs - the relics of giant gas clouds torn apart by encounters with black holes.
They made the discovery after developing computer simulations of giant gas clouds being sucked into black holes like water spiralling down a plughole.
"These simulations show that young stars can form in the neighbourhood of supermassive black holes as long as there is a reasonable supply of massive clouds of gas from further out in the galaxy," said co-author Ian Bonnell from St Andrews University, UK.
Ripped apart
Their findings are in accordance with actual observations in our Milky Way galaxy that indicate the presence of a massive black hole, surrounded by huge stars with eccentric orbits.
The simulations, performed on a supercomputer - and taking over a year of computing time - followed the evolution of two separate giant gas clouds up to 100,000 times the mass of the Sun, as they fell towards the supermassive black hole.
The simulations show how the clouds are pulled apart by the immense gravitational pull of the black hole.
The disrupted clouds form into spiral patterns as they orbit the black hole; the spiral patterns remove motion energy from gas that passes close to the black hole and transfers it to gas that passes further out.
This allows part of the cloud to be captured by the black hole while the rest escapes.
In these conditions, only high mass stars are able to form and these stars inherit the eccentric orbits from the elliptical disc.
These results match the two primary properties of the young stars in the centre of our galaxy: their high mass and their eccentric orbits around the supermassive black hole.
"That the stars currently present around the galaxy's supermassive black hole have relatively short lifetimes of [about] 10 million years, which suggests that this process is likely to be repetitive," Professor Bonnell explained.
"Such a steady supply of stars into the vicinity of the black hole, and a diet of gas directly accreted by the black hole, may help us understand the origin of supermassive black holes in our and other galaxies in the Universe."

Milky goes black



There is a giant black hole at the centre of our galaxy, a 16-year study by German astronomers has confirmed.

They tracked the movement of 28 stars circling the centre of the Milky Way, using two telescopes in Chile.

The black hole, said to be 27,000 light years from Earth, is four million times bigger than the Sun, according to the paper in The Astrophysical Journal.

Black holes are objects whose gravity is so great that nothing - including light - can escape them.

According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit.

'The black pearl'

Dr Massey said: "Although we think of black holes as somehow threatening, in the sense that if you get too close to one you are in trouble, they may have had a role in helping galaxies to form - not just our own, but all galaxies.

"They had a role in bringing matter together and if you had a high enough density of matter then you have the conditions in which stars could form.

"Thus the first generation of stars and galaxies could have come into existence".

The researchers from the Max Planck Institute for Extraterrestrial Physics in Germany said the black hole was 27,000 light years, or 158 thousand, million, million miles from the Earth.

"Undoubtedly the most spectacular aspect of our 16-year study, is that it has delivered what is now considered to be the best empirical evidence that super-massive black holes do really exist," said Professor Reinhard Genzel, head of the research team.

"The stellar orbits in the galactic centre show that the central mass concentration of four million solar masses must be a black hole, beyond any reasonable doubt."

Observations were made using the 3.5m New Technology Telescope and the 8.2m Very Large Telescope (VLT) in Chile. Both are operated by the European Southern Observatory (Eso).

Conquest of Space



Film (1955) directed by George Pal and partly inspired by Ley and Bonestell's book. In a thematic sense, Conquest follows on from Pal's Destination Moon (1950), taking space exploration beyond the Moon to interplanetary space and, in particular, a manned journey to Mars. Although the characterization is poor and the dialogue often inane, there are some memorable scenes, including those of a rocket attempting to outrace a pursuing asteroid and a wheel-like space station, designed along the lines proposed by Wernher von Braun.




Eraserhead



Eraserhead is a surrealist-horror film written and directed by David Lynch, and released in 1977.

Metropolis



Metropolis is a 1927 silent science fiction film directed by Fritz Lang and written by Lang and Thea von Harbou. Lang and von Harbou, who were married, wrote the screenplay in 1924, and the story was novelized by von Harbou in 1926. It is set in a futuristic urban dystopia and examines a common science fiction theme of the day: the social crisis between workers and owners in capitalism. The film stars Alfred Abel as the leader of the city, Gustav Fröhlich as his son, who tries to mediate between the elite caste and the workers, Brigitte Helm as both the pure-at-heart worker Maria and the debased robot version of her, and Rudolf Klein-Rogge as the mad scientist who created the robot.

Que Sera Sera



wax tailor

After being a host on a French radio in the Paris suburb of Mantes-La-Jolie, JC Le Saout started the French Rap band La Formule in the 1990's. He created his label Lab'Oratoire in 1998 and produced records from La Formule as well as Break Beat compilations and a collaboration with the Swedish band Looptroop. He began work on the Wax Tailor project in 2001, first appearing on a remix of Looptroop & La Formule's "Breathing Under Water". Wax Tailor's first EP Lost The Way was released in 2004 and features contributions from Charlotte Savary, Marina Quaisse, and Big Dada rapper Infinite Livez. Other musicians who have appeared alongside Wax Tailor include North Carolina Hip-Hop duo The Others, Ursula Rucker, Sharon Jones, Voice and A State Of Mind.

His second album Hope & Sorrow was nominated for "Best Electronic Album" at the 2008 Victoires de la Musique
