A First Africa Wide Amateur Radio Contact Experiment with the International Space Station

The Amateur Radio on the International Space Station (ARISS) program is recognized by its great Science, Technology, Engineering, and Mathematics (STEM) impact: it brings space science to education and outreach initiatives by enabling direct contact with astronauts in orbit and other space savvy professionals. Strategic partnerships between ARISS and digital platforms for citizen science act as a powerful real-world STEM motivator and can overcome logistical barriers, demonstrating a scalable model for inclusive outreach, sparking curiosity in space exploration and STEM careers among underrepresented communities. As a case study, this article focus on the impact of an historic milestone: on April 18$^{th}$ 2025 the Pan-African Citizen Science e-Laboratory (PACS e-Lab) orchestrated the first Africa-wide ARISS contact experiment and connected 300 students, educators, and STEM enthusiasts from 38 African nations and beyond with NASA astronaut Nichole Ayers aboard the ISS Expedition 72. Within the African context, this initiative not only inspired a new generation of African scientists, but it also set a precedent for wider collaboration on space science education across the continent. Strategic partnership between ARISS and PACs e-LAB promotes capacity building through international and regional cooperation on space science and adds a new "New Space" narrative that emphasizes the interconnectedness of space with our daily lives and the possibility that everyone has to be a part of it.

Investigation into Pulsar Glitch Parameters

An updated analysis of pulsar glitch parameters was conducted using a sample of 215 pulsars, encompassing 677 recorded glitch events, each glitch at least once between 1968 and 2024. The glitch rates were estimated and plotted against various pulsar parameters, including rotational frequency, spin-down rate, and characteristic age. These relationships were analyzed using Pearson's correlation coefficient. The results indicate linear and weak relationships between glitch rate and the pulsar parameters. However, the relationship between glitch rate and characteristic age is inversely weak.

Pan-African Asteroid Search Campaign: Africa's Contribution to Planetary Defense

Asteroid search is a global effort for planetary defense. The International Astronomical Search Collaboration (IASC) is the leading global educational outreach program that provides high-quality astronomical datasets to citizen scientists to discover asteroids. Since December 4, 2020, the Pan-African Citizen Science e-Lab (PACS e-Lab) has been IASC's biggest partner on the continent in recruiting and training citizen scientists in asteroid search endeavors. Over 30 asteroids have been discovered by 60 citizen scientists. About 595 citizen scientists from over 40 countries have been engaged in the project up to the time of composing this literature. The group is set to expand its endeavors to the rest of the continent and aims to engage thousands of citizen scientists.

Pan-African Citizen Science e-Lab: An Emerging Online Platform for Astronomy Research, Education and Outreach in Africa

Citizen science offers an opportunity for ordinary people, known as citizen scientists or citizen astronomers in the context of astronomy, to contribute to scientific research. The Pan-African Citizen Science e-Lab (PACS e-Lab) was founded to promote and engage the African public in citizen science and soft astronomy research to advance space research and exploration and enhance space education and outreach. PACS e-Lab, in collaboration with several international astronomy research, education, and outreach organizations, currently runs several projects including but not limited to asteroid search, exoplanet photometry, research writing for peer-reviewed publications, astrophoto visual development, and Amateur Radio contact with astronauts aboard the International Space Station (ARISS). Despite several challenges, the group has engaged over 600 Africans from more than 40 countries and is working towards covering the entire continent in the future. PACS e-Lab's development efforts resonate with seven United Nations Sustainable Development Goals (UN-SDGs).

Astrometric Measurement of the Double-Star System WDS 09168-3407 B 1118

We present updated measurements for the position angle and separation of the double-star WDS 09168-3407 B 1118, incorporating data from our observation, Gaia Early Data Release 3 mission, and historical records. Our findings indicate a position angle of 341.4° and separation of 3.36". Additionally, we utilized parallax and the ratio of proper motion metric (rPM) values to evaluate the potential binarity of the system. Our analysis suggests that the system may be gravitationally bound.

New Astrometric Measurements of the Position Angle and Separation of the Double Star System WDS 03245+5938 STI 450

We report new measurements of the position angle and separation of the double star WDS 03245+5938 STI 450, based on our observations, Gaia EDR3, and historical data. We find that the position angle and separation are 209.7° and 7.68", respectively, showing slight changes from the previous values of 210° and 7.742". We also find that the distances between the two stars are far apart, suggesting that the system is an optical double, and therefore not gravitationally bound together. Furthermore, we find that the ratio of proper motion (rPM) metric of the system is distinct, indicating that the system is a chance alignment of two unrelated stars that are at different distances.

Measurement of the Double Star System WDS 03286+2523 BRT 133 with a Web Telescope

WDS 03286+2523 BRT 133, is a double-star system that has been under observation since 1896. In this study, we present new measurements of the position angle and separation of the system, utilizing data obtained from a web telescope with a Charged Couple Device (CCD) camera, Gaia EDR3, and historical records. We determined that the position angle and separation are 222.4° and 5.35", respectively, indicating a slight increase from the previous values of 222° and 5.34" measured in 2004. We also employed the parallax and the ratio of proper motion metric (rPM) values of the system to assess its binarity. This analysis showed that the system may be gravitationally bound and with a long orbital period.
