Our mission

  • To contribute towards a positive change in the world through expanding the knowledge of astronomy and related sciences.
  • To unify our communities by providing any knowledge related to astronomy and science to all who wish to learn, and to offer useful tools and resources to any person interested in passing down that knowledge.

Your donations could make a huge difference for a student, child or teacher. Thanks for your help!






We just introduce a petition about a new threat to astronomy.

We encourage you to read and sign it. It’s about the constellations of low earth internet satellites (including Starlink and others). We are sure you are interested in this topic, because this is a common interest for all of us. We intend to send it to all the companies and CEO’s. We need all your support! Please use this link to sign it:

Call to Internet satellite constellations companies to prevent the pollution of the night sky, and to help and collaborate with astronomers.

Don’t forget to talk about to your friends and family, thanks!

Events in Astronomy

Here you can find events around the world. For South Florida events, visit the “Activities” page.

Astronomy Day

The first Astronomy Day this year is in the Spring: May 2, 2020; Astronomy Day next fall will be Wednesday September 23, 2020. Astronomy Day is an annual event in the United States and other countries, intended to provide a means of interaction between the general public and various astronomy enthusiasts, groups and professionals. This event was started in 1973 by Doug Berger, the president of the Astronomical Association of Northern California. His intent was to set up various telescopes in busy urban locations so that passersby could enjoy views of the heavens. Since then the event has expanded and is now sponsored by a number of organizations associated with astronomy. The lunar influence on the schedule means that the events happen on a different date each year, rather than set calendar dates. Astronomy Day also forms part of National Astronomy Week, which begins on the preceding Monday.

World Space Week

 The General Assembly of United Nations declared 4 to 10 October World Space Week to celebrate each year at the international level,  all contributions of space science and technology to the betterment of the human condition. More than 3,700 events in 80 countries celebrated the benefits of space and the excitement about space exploration in 2017.  The theme for World Space Week 2020 will be “Satellites Improve Life”.

International Observe the Moon Night

International Observe the Moon Night is a worldwide celebration of lunar science and exploration held annually since 2010. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest neighbor. The event occurs in September or October, when the Moon is around first quarter. A first quarter Moon is visible in the afternoon and evening, a convenient time for most hosts and participants. Furthermore, the best lunar observing is typically along the dusk/dawn terminator, where shadows are the longest, rather than at full Moon. There are currently 184 events and participants.
 Plan Ahead, date for International Observe the Moon Night:
September 26, 2020

This year’s celebrations begin on Sunday, April 19, and run through Sunday, April 26, 2020.In explaining why she started the week, Barlow said, “I want people to be able to see the wonder of the night sky without the effects of light pollution. The universe is our view into our past and our vision into the future. … I want to help preserve its wonder.”International Dark Sky Week draws attention to the problems associated with light pollution and promotes simple solutions available to mitigate it.
