The Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) project is making available to the scientific community the first 12 square degrees of the three-dimensional map of the Universe that it is carrying out from the Javalambre Astrophysical Observatory. The area studied contains 550,000 astronomical objects and is only a small sample of the full survey area, which will observe thousands of square degrees over 10 years.

The Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) releases the first set of data, corresponding to a sky area of one square degree observed at the well-known Extended Groth Strip. The data release contains a catalogue of more than 60,000 astronomical objects, each of them having more than a thousand parameters, including multi-band photometry in the unique set of 56 narrow-band (14 nm width) optical filters of J-PAS.
