In preparation for its final switch-off on 23 October, mission controllers today fired Planck’s thrusters to empty its fuel tanks. The burn is one of the final steps to ensure that Planck ends its hugely successful mission in a permanently safe configuration.
All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck’s law. If, however, the radiating object is smaller than the thermal wavelength, it behaves according to different rules and cannot emit the energy efficiently.
An international team of scientists at the Planck observatory has made the closest reading yet of the most ancient story in our universe: the cosmic microwave background (CMB).
For the first time, ESA's Planck space telescope has detected a bridge of hot gas connecting a pair of galaxy clusters 10 million light-years apart.
New images from the European Space Agency’s Planck mission have revealed previously undiscovered islands of star formation, along with a mysterious haze of microwave emissions in our Milky Way galaxy.
The European Space Agency has released the fist results from its Planck mission, focusing on the coldest objects in the universe.
The Planck telescope team has released its first full-sky picture - the clearest yet taken, showing the glow of the first light in the universe.
