Elon Musk's Starlink: a threat to South Africa's astronomical research?
One of the 64 MeerKAT Telescopes observing our skies. Image: UWC The prospect of Elon Musk's satellite internet venture, Starlink, expanding its operations to South Africa has generated considerable excitement, particularly for its potential to bridge the digital divide in rural communities. However, experts in the field of astronomy are raising concerns about the unintended consequences of satellite constellations on South Africa's world-class radio telescopes. University of the Western Cape (UWC) Professor Lerothodi Leeuw recently spoke to Cape Talk radio about the disruptive impact that Starlink and similar satellite networks could have on the country's premier astronomical facilities. Among those at risk are the Southern African Large Telescope (SALT), a state-of-the-art observatory in Sutherland, and the ambitious Square Kilometre Array (SKA) project, designed to unlock new insights into the universe. Prof Leeuw likened the interference caused by satellites to a form of 'photo-bombing,' where artificial radio signals intrude upon critical observations. He emphasised that this issue is not new, but Starlink's growing prominence has renewed discussions around mitigating the effects of space-based transmissions. South Africa has invested significantly in its radio telescope infrastructure, and authorities have implemented strict regulations to minimise interference from terrestrial sources. The SKA site, for instance, is located within a designated radio-quiet zone. However, Prof Leeuw pointed out that these safeguards do not extend beyond national borders, leaving space-based satellites outside the scope of local regulations. Professor Lerothodi Leeuw Image: UWC 'We don't control low Earth-orbiting satellites,' he noted, highlighting that Starlink is not the only operator deploying satellite constellations. Other ventures, such as OneWeb and Project Kuiper, also contribute to the challenge. Despite the difficulties, Prof Leeuw remains optimistic that measures can be put in place to mitigate the problem. He suggested that temporarily disabling satellites while they pass over sensitive areas could help prevent interference. 'There is potential to mitigate the problem by turning off satellites for just a few seconds as they cross the region, without affecting transmission elsewhere,' he explained. Some scientists have already approached Starlink to explore solutions, leading to adjustments in satellite design. These include adding optical reflectors to redirect light away from telescopes or modifying the satellites' surfaces to reduce glare. However, altering orbital paths to completely avoid interference remains impractical. Prof Leeuw underscored the significance of this issue within the scientific community. He revealed that a conference dedicated entirely to tackling satellite interference was held last year, although discussions on radio astronomy only occupied half a day, showing that the subject, while growing in importance, remains under-addressed. As satellite constellations continue to proliferate, experts in astronomy are urging operators to take more proactive steps to minimise their footprint on scientific exploration. The balance between global connectivity and preserving the integrity of astronomical research is a delicate one, and finding solutions will require coordinated effort between governments, scientists and satellite providers alike.

High-school student accidentally discovers black hole 'light echo' twice as wide as the Milky Way
When you buy through links on our articles, Future and its syndication partners may earn a commission. ANAHEIM, Calif. — Long after the black hole in the center of a galaxy sputters out, you can still see its ghost lingering in surrounding gas clouds aglow with leftover radiation, like wisps of smoke emanating from an already extinguished flame. Astronomers call these cosmic ghosts "light echoes" — and that's what high-school junior Julian Shapiro found while scanning the cosmos for supernova remnants. "There are these outer regions of gas being ionized by a supermassive black hole, which results in this echo," Shapiro said at a March 20 presentation here at the 2025 American Physical Society (APS) Global Physics Summit. Shapiro, 17, is a student at The Dalton School in New York City. But in between classes and scoping out potential colleges, he's also an independent astronomer who presents at global conferences like this week's APS meeting. Originally, Shapiro began sifting through the DECaPS2 survey — an inventory of the southern galactic plane from the Dark Energy Camera at the Cerro Tololo Inter-American Observatory in Chile — to find the debris of exploding stars in supernova remnants and planetary nebulas. But after zeroing in on one such object, he found its structure didn't match the wispy filaments characteristic of a supernova remnant, nor did it show evidence of a supernova at its center. "It was a real surprise to stumble upon this," Shapiro told Live Science. Related: High school students who came up with 'impossible' proof of Pythagorean theorem discover 9 more solutions to the problem The object, which he believes to be a light echo, stands in a field of potential supermassive black holes. Using measurements from the Southern African Large Telescope, he found high contents of oxygen and ionized sulfur sprinkled into the region — both indicators of shocked material. All of these signs suggest that the object is the afterglow of a now-dormant black hole, which once spewed radiation that ionized the surrounding gas, causing it to emit light even after the black hole quieted down. Shapiro currently pegs the light echo at about 150,000 to 250,000 light-years in diameter — about 1.5 to two times the width of the entire Milky Way galaxy. And if his estimates hold up, he thinks it could be a viable candidate for the largest light echo ever discovered. "This object covers a large area in the sky, which makes it a bit easier to get in-depth images of," Shapiro said. According to Sasha Plavin, a black hole researcher at Harvard University who was not involved in the research, echoes like the one Shapiro discovered can help us learn more about how black holes behave in the hearts of galaxies. "I really like how carefully [Shapiro] looked into these images," Plavin told Live Science. "These galactic events are always of interest, and I think these echoes are a great way of studying them." Plavin is also interested in seeing how this new light echo measures up to others — whether it occurred faster or slower than existing examples. "Putting this discovery in a wider context could be useful in the future," he said.

This James Webb Space Telescope discovery might blow your mind —Evidence for Stephen Hawking's unproven black hole theory may have just been found — at the bottom of the sea As Shapiro continues studying the light echo, he hopes to learn more about its composition with measurements of its different regions. But in the meantime, he's excited to continue contributing to black hole science — even if he came across it by accident. "My involvement in this area of research came as a bit of a surprise to me," he said. "But I hope this object, in particular, helps expand the knowledge of galaxy activities that we don't have too great of an understanding of."
