Astronomy 2024 Full Moon Hike

April 2, 2023/in Africa, Astronomical events, Outreach/by Duduzile

Efforts are underway as we gear up for the International Astronomical Union’s General Assembly 2024 meeting. Our Ambassador and University of Cape Town (UCT) student, Venu Prayag, organized a Full Moon Hike which was held on Tuesday, 7 March 2023. Although the weather threatened to spoil this exciting event, we were, fortunately, able to proceed and enjoy a great evening outdoors, and experienced the scenic beauty and beautiful city lights and night sky from the top of one of Cape Town’s must-see destinations, Lion’s Head, which offers picturesque and breathtaking views of the city.

Everyone was amazing in helping and caring for one another and made this a fun and safe experience for all. It was inspiring to hear members of the public getting excited about spotting Venus on the horizon and their stories about stargazing in the Kruger National Park.

We are looking forward to more fun and educational activities in the future and hope a lot more of you can join us.

NB: Look out for a call for more ambassadors to be released soon.

10 December: Come hear about the JWST, by JWST scientists

December 7, 2021/in AfAS, Astronomical events/by wpadmin

JWST stands for James Webb Space Telescope. This is the new generation telescope that will overtake the Hubble Space Telescope after over 30 years of incredible astronomical images and science.

The JWST is due to launch on 22 December this year, and a lot is at stake. To learn more about this feat of science and technology, join us:

on 10 December 2021 at 13:00 – 15:00 GMT as we speak to:
Dr. Sarah Kendrew from the European Space Agency and the Space Telescope Science Institute in the USA, and
Mr. Robel Geda from Princeton University, USA.

Registration to the Zoom webinar

If you don’t register, the talks will be live on YouTube as well at this link.

Solar Eclipse of 4 December 2021

December 3, 2021/in Africa, Astronomical events, News/by wpadmin

The moon will pass in front of the sun, covering it on 4 December 2021. It will be visible partially from the Southernmost parts of the continent. For more information and instructions on when and how to observe this partial solar eclipse safely, see the poster below.

Enjoy the event and if you would like to share photos of your observations, feel free to email us at IAUGA2024@afasociety.org. And remember, never look at the sun directly or through an instrument!

Large fireball illuminates Southern African skies

August 25, 2021/in Africa, Astronomical events, News/by wpadmin

On the evening of August 24, a bright object traveling fast in the upper atmosphere had thousands of people mesmerised. It was spotted by many in the Gauteng province of South Africa but was visible further North into Limpopo and Zimbabwe. At first we didn’t know what it was.

A usual shooting star is a rock the size of a grain of sand, so this looked a lot larger and it could be seen breaking up in the atmosphere. We’re lucky it happened after sunset, otherwise it would not be visible.

It could also have been something made by humans. Indeed, space is full of the debris of our interplanetary dreams. In 2001, the Russian Space Station Mir ended its faithful service to humanity in a stunning fireball above the Pacific Ocean.

Rockets reach space in stages. Until Elon Musk’s SpaceX Falcon 9 landed back on Earth, rockets used to be discarded in space after one launch, and only capsules used to come back to Earth. One such capsule can be seen at the Cape Town Science Centre in South Africa. This is one of the reasons space travel was so expensive. OK it still is – but less so, and space has even become the next frontier in terms of tourism for the very wealthy.

This single-use approach to space travel also created a lot of large debris. This debris eventually falls back onto Earth. When large human-made objects orbit the planet they are often monitored, as they could present a hazard for satellites, aircraft, or us on the ground.

Thanks to this, astronomer and space geek Jonathan McDowell as well as twitter user @Skitt0608 were able to identify last night’s object as Chinese rocket Yuanzheng-1S, meant to demonstrate satellite internet provision capabilities.

OK if I assume that the YZ-1S stage made a deorbit burn at about 1230 UTC to an orbit around 100 x 1100 km but it failed to reenter at first or second perigee, surviving to the third perigee, I get a good match with the time and location of the observations pic.twitter.com/YkkHZHdC1s

— Jonathan McDowell (@planet4589) August 24, 2021

So there you have it: it was a piece of rocket, re-entering the atmosphere and burning up due to friction with air molecules. As more of our space junk falls back to Earth we may see more of these human-made shooting stars.

If you want to work in space, here’s what to do: take mathematics and science at school, enroll in a physics degree, or an engineering degree, and dream big! Who knows where this could take you?

Celebrate Africa Day on May 25th with your stories of the Moon

May 19, 2021/in AfAS, Africa, Astronomical events, News, Outreach/by wpadmin

25 May is celebrated as Africa Day every year. There will be a lunar eclipse on 26 May this year, which cannot be seen from Africa, but – the whole world share the same sky, right? And as Africans we have always had a special relationship with the Moon.

Therefore, we want to use the Moon to bring all of us Africans together. In collaboration with the African Astronomical Society, we invite you to share your stories and songs about the Moon. 

How to take part:

We invite you to create a 2-3 minute video on your phones of your stories and songs, either as a selfie or of someone you know telling it. Send them to us through

WhatsApp: +27 (0)82 403 0908
Email: outreach@afasociety.org 

We will celebrate Africa day by sharing your stories with the world. Please also send us your name, email address and location.
