Nibiru-Astronomical Society (Spanish: Sociedad Astronomica) is a non-profit academic and student astronomical society created at the Faculty of Sciences (UNAM) of the National Autonomous University of Mexico in 2001.

The goal of the society is to create a channel linking students studying physics at the Faculty with astronomers at the Institute of Astronomy (UNAM).^[1] This is achieved through year-round biannual astronomy related activities such as conferences, courses, movie debates,^[2] planetary observations through telescopes and outings focused on archeoastronomy.

On March 24, 2009, Nibiru opened up a new astronomical society at the Metropolitan Autonomous University in Azcapotzalco (Mexico City), known as Nibiru UAM. The UAM served as a hub for student-academic astronomical activities at the north of the city until April 2010. A new astronomical society derived from the pilot program, as intended.

It has performed several important observations^[3][4] of astronomical phenomena, such as solar and lunar eclipses, and has been noted on several national newspapers and television stations for its activities.^[5][6] It has also toured several faculties at the University,^[7][8] creating awareness of astronomy and light pollution through telescope observations of Jupiter, Saturn, Mars and the Orion Nebula.

Several important Mexican scientists from the UNAM have participated in conferences^[9] on cosmology, general relativity and astrobiology organized by the Society:

• Carlos Frenk
• Miguel Alcubierre
• Antonio Lazcano

In 2009, the Society assisted Mexican authorities with activities celebrating the International Year of Astronomy, becoming the astronomical society with the most events nationwide.
