What data is used to create the star map?

Hipparcos was a satellite launched by the ESA (European Space Agency) in 1989, which remained active until 1993, collecting information on more than 2.5 million stars.
The results of this work were published in a catalog called Tycho-1, which was made public in 1997 and is in the public domain.

This catalog is considered one of the most precise and contains a large amount of astrometric information that allows us to project the alignment of stars with remarkable accuracy.

For detailed information about the Tycho-1 catalog and the Hipparcos satellite, please visit the mission’s dedicated website by following this link.

Pulso Astral has a star map generator software that uses this catalog to determine the position of the stars on a specific date as seen from any point on the planet Earth. This allows us to offer you an astronomically accurate product that you can create yourself with just a few clicks.

In summary, a perfect gift that uses advanced technology to surprise a loved one.
