Ghosts of the radio universe’: astronomers have discovered a slew of faint circular objects



Astronomers have uncovered a fascinating new class of cosmic phenomena—faint circular objects (FCOs)—dubbed the "ghosts of the radio universe." These enigmatic structures appear as ghostly rings in deep-space radio surveys, defying easy classification. Unlike supernova remnants or distant galaxies, these newly discovered objects challenge existing astrophysical models, hinting at unknown mechanisms shaping our universe.




FCOs were first detected using advanced radio telescopes such as the Square Kilometre Array Pathfinder (ASKAP) and MeerKAT. Their faint, circular appearance suggests they might be remnants of ancient cosmic explosions, radio halos surrounding distant galaxies, or even exotic manifestations of extreme astrophysical processes. However, their exact nature remains elusive, sparking intrigue among astronomers worldwide.

One leading hypothesis proposes that these structures could be fossil radio emissions from past activity of supermassive black holes, now fading over eons. Alternatively, they might be massive shockwaves propagating through intergalactic space, revealing a previously unseen aspect of large-scale cosmic interactions. Their rarity and faint signals make them difficult to detect, suggesting that many more could be lurking unseen in the depths of the cosmos.

The discovery of FCOs opens new avenues for research into the radio sky's hidden secrets. These ghostly signals may help scientists understand the life cycles of galaxies, the fate of cosmic jets, and the interplay between dark matter and interstellar gas. With the upcoming next-generation radio observatories, such as the Square Kilometre Array (SKA), astronomers hope to uncover more of these mysterious rings and decode their origins.

As technology advances, we are gaining deeper insights into the universe’s most enigmatic structures. These faint radio circles, whispering across the cosmic void, remind us that the universe is still full of surprises. The ghosts of the radio universe beckon us to explore further, unveiling the secrets hidden in the radio frequencies that permeate the cosmos.

Does AI pose a threat to sustainable development?

Image
  The 2025 World Economic Forum, being held in Davos from Monday to Friday under the theme " Collaboration for the Intelligent Age ", is expected to foster a spirit of cooperation and optimism in the digital age in a more sustainable way, despite the different positions of the participants and global uncertainties. Three experts share their views on the issue with China Daily. Projected estimates indicate that advanced artificial intelligence (AI) systems will necessitate over $1 trillion in investments for cloud and enterprise data center infrastructure within the next five years. The AI infrastructure includes servers equipped with graphics processing units (GPUs) or custom accelerators, dedicated networks, storage solutions and specialized facilities, which are all factors that demand significant capital investment. Therefore, evaluating the scale, potential returns and environmental impact of AI's rapid development and application is essential. The rise of AI will si...

Building urban resilience to climate change

Image
  Building Urban Resilience to Climate Change is an essential framework for cities to safeguard their infrastructure, ecosystems, and populations from the increasing threats of climate change. As urban areas grow and climate impacts intensify, it's crucial to develop adaptive measures that not only reduce vulnerabilities but also promote sustainable urban development. This approach involves a variety of strategies, including enhancing green infrastructure, improving water and energy management, promoting low-carbon transportation, and integrating climate adaptation into urban planning. Urban resilience focuses on creating systems that are both adaptable and responsive to climate stressors like heatwaves, flooding, and storms. By prioritizing nature-based solutions such as urban parks, green roofs, and wetlands, cities can mitigate heat island effects, improve air quality, and protect biodiversity. Moreover, integrating sustainable architecture, resilient infrastructure, and effici...

'Our model of cosmology might be broken': New study reveals the universe is expanding too fast for physics to explain

Image
 A recent study has revealed a puzzling discrepancy in our understanding of the universe’s expansion rate, suggesting that our current cosmological models may need a significant overhaul. The crux of the issue lies in the Hubble constant (H₀), a measure of the universe's expansion rate, which appears to differ depending on how it is calculated. For decades, scientists have relied on two primary methods to determine H₀. The first involves observing the cosmic microwave background (CMB), the faint afterglow of the Big Bang, and extrapolating the universe's expansion rate using early-universe physics. The second method uses the local universe, measuring distances to nearby galaxies via "standard candles" like Cepheid variables and Type Ia supernovae. However, these two methods yield conflicting results. The CMB method, based on data from missions like Planck, estimates H₀ to be around 67.4 kilometers per second per megaparsec (km/s/Mpc) . In contrast, local measurements...
