This weekend, after sunset, we can observe a beautiful conjunction of Venus with the crescent Moon. On the 26th, our satellite will be in conjunction with Mars.

The seasons continue to advance following the rhythm marked by the great cosmic clock of the celestial vault.Rafael Bachiller is director of the National Astronomical Observatory (Instituto Geográfico Nacional) and academician of the Royal Academy of Doctors.
