Read the story

Euclid’s DR1-Foundation release brings together approximately 13 months of observations, ESA announced on November 12. It records light from over a billion objects.

Researchers can now begin constructing a detailed three-dimensional cosmic map. Such mapping is intended to help investigate dark matter and dark energy, rather than establish that those mysteries have already been solved.

Read and practise

1. What does DR1-Foundation bring together?

   1. Only observations from November 12
   2. A completed three-dimensional map
   3. Approximately 13 months of observations

2. Why would claiming the mysteries are solved be unsupported?

   1. The observations contain only dark matter
   2. The text describes investigation as an aim
   3. The telescope records no light

Your turn

Describe the available evidence and one conclusion the text does not support.
