Movie - DESHIMA Stargazing & Nanotechnology

News - 27 December 2017 - Communication

Imagine you could look at the early beginnings of our universe, looking back into space and time. Light, which has travelled from these early beginnings of the universe to our earth in between 10 and 13 billion years, can now be measured by DESHIMA. DESHIMA - developed by the TU Delft in collaboration with SRON (Netherlands Institute for Space Research), Leiden Observatory and Japanese astronomers - is the birth of a new technology. It allows scientists to address the question of the whole history of the universe: from the first galaxy to where we are now.

DESHIMA is a wideband spectrometer, one or two orders more than existing ones. This means you can point it at a particular galaxy of which you don't know the redshift, and you can rapidly determine the redshift of that galaxy and move on to the next one. Scientists captured first light from Saturn falling on DESHIMA on November the 20th of 2017.

The baseline goal of this mission in Chile, to get DESHIMA working on the ASTE Telescope, has been a success. The scientists will be able to create the first 3D maps of galaxies dating back to the dawn of our universe.

The next challenge for the coming year is a technological upgrade from this prototype to a full-scale science instrument. The development will continue to take place in the Terahertz Sensing Group/Cryolab of TU Delft, and students are encouraged to participate.
