Clumps of Cold Stuff Across the Sky
This map illustrates the numerous star-forming clouds, called cold cores, that Planck observed throughout our Milky Way galaxy. Planck, a European Space Agency mission with significant NASA participation, detected around 10,000 of these cores, thousands of which had never been seen before. Cold cores are chilly chambers of gas and dust where stellar embryos are just beginning to take shape. Some of the cold cores found by Planck are the coldest ever observed, as cold as just seven degrees above absolute zero, or minus 447 degrees Fahrenheit.
Planck unveils the Universe - UK Space Agency
“The Planck space satellite – ESA’s mission to study the early Universe - has delivered its first image of the entire sky. By looking at microwave radiation, it not only provides new insight into the way stars and galaxies form, but also tells us how the Universe itself came to life after the Big Bang.
This single image captures both our own cosmic backyard – the Milky Way galaxy that we live in – but also the subtle imprint of the Big Bang from which the whole Universe emerged.
The dust throughout the Galaxy is shown in blue, while hot gas can be seen as red regions across the centre of the image. In the background, the mottled yellow features are relic radiation, called the Cosmic Microwave Background, which contains information about the earliest stages of the Universe.”
Engineers dressed in Self-Contained Atmospheric Protective Ensemble, or SCAPE suits, fuel Planck with liquid hydrazine on 15 April 2009.
Planck will use its thrusters, propelled by liquid hydrazine, for manoeuvres once in orbit. This is a volatile and toxic substance, commonly used as rocket fuel. The critical fuelling operations required plenty of preparation, including safety training exercises for the fuelling team, and was executed with great care.
