World Space Week is a UN declared celebration of space held annually, every October 4 to 10. It is the largest space event on Earth, with over 8,000 events reported in 2019 and held in 96 countries. These events are organized by thousands of organizations, including space agencies, aerospace companies, astronomy clubs and museums.
The 2020 World Space Week is dedicated to satellites and their broad benefits under the theme “Satellites improve life.” With this theme, the World Space Week will show the importance of satellites in daily life and how our lives are affected by satellites such as in communications, environmental monitoring, transportation, weather forecasting, telemedicine, science, and in many other ways.
Next to Scorpius, and directly above the direction of South is Sagittarius, the Archer. As seen above, it is more recognisable by its relatively bright stars forming the shape of a Teapot. Positioned right below the Galactic Centre itself, Sagittarius is a treasure trove of deep sky objects that can be relatively easily found by utilising its bright stars.
Starting from the teapot itself, near the top of the teapot, M22, a globular cluster, can be found by extending a line from Kaus Borealis (the closest easily visible star in the direction of the Wow! signal!) to Polis. The line can then be extended further on to find M23, another open cluster. One can also extend a line from Phi Sagittarii (φ Sgr) through Kaus Borealis, to find the Trifid Nebula (M20). Thereafter, Lagoon Nebula (M8) and M21, an open cluster, can be found by going southwards and northwards respectively from M20. M25, an open cluster, can also be found by extending a line through Kaus Borealis from Kaus Australis.
Moreover, one can also find the Wild Duck Cluster (M11) by extending a line through Kaus Borealis from Kaus Media. Penultimately, by extending a line through Polis from Alnasl, one can find M24, an open cluster, the Omega Nebula (M17), NGC 6605, an open cluster, the Eagle Nebula (M16), as well as NGC 6604, another open cluster, in sequential order. Lastly, one can find the following open clusters by extending a line through Alnasl from Nunki: Butterfly Cluster, NGC 6416, NGC 6384 and NGC 6374.
