The concept of black holes fascinates scientists and laypeople alike, evoking images of cosmic vacuum cleaners that consume everything in their vicinity. However, recent studies propose a more nuanced understanding of these enigmatic objects. In particular, tiny primordial black holes (PBHs) may not only exist but could also be zipping through our Solar System more

As humanity strides further into the realm of space exploration, the need for efficient and standardized systems on celestial bodies has become increasingly evident. Missing a train or bus can derail one’s day, but imagine missing your spacecraft home. NASA is addressing this profound concern by working on the establishment of Coordinated Lunar Time (LTC)
When discussing cosmic phenomena, few events are as extraordinary or influential as a supernova explosion. These colossal eruptions not only release an immense amount of energy that brightens entire galaxies, but they also play a crucial role in shaping the very fabric of our universe. Notably, supernovae are instrumental in the creation of heavy elements,
Dark matter, a term that has puzzled scientists for decades, derives its name not from the notion of being shadowy or elusive but rather from its intrinsic inability to interact with light. Unlike ordinary matter, which can absorb, emit, and scatter light due to the electromagnetic forces exerted by charged particles within atoms, dark matter
The fascination with finding a second Earth is a pursuit that has captivated astronomers and scientists for decades. With the vast expanse of the Milky Way galaxy stretching before them, researchers are constantly on the lookout for exoplanets that could harbor life or resemble our home planet. A recent discovery has added a new dimension
Astronomers continuously seek to understand the vast complexities of our Universe, and one of the most intriguing phenomena they encounter are gravitational lenses. Serving as natural magnifying glasses, these cosmic structures not only distort the light from distant celestial objects but also offer a profound glimpse into the depths of cosmic history. Recently, a significant
For long, the Moon has been perceived as devoid of significant water resources, almost akin to a barren wasteland. Recent geological analyses, however, have turned this notion on its head. Contrary to the previous belief that water on the lunar surface was limited primarily to the frigid polar regions, new findings indicate that both water
Far beyond the reaches of our solar system, approximately 5,825 light-years away, a red giant star has become the focus of intense astronomical scrutiny. Labeled G3425, this star is not merely twinkling in solitude; instead, it appears to be engaged in an unusual orbit with an unseen binary companion. What makes this observation particularly intriguing
Astronomy continuously presents us with dazzling spectacles, yet few phenomena capture our imagination quite like star clusters. Among these celestial wonders is the Palomar 5 globular cluster, situated approximately 80,000 light-years away from Earth. Marked by a unique distribution of stars, Palomar 5 homes a striking secret—over 100 stellar-mass black holes. Such discoveries not only
As the number of satellites in low Earth orbit continues to surge, the implications for astronomical research and the overall environment have become increasingly dire. Notably, the rise of satellite constellations, particularly SpaceX’s Starlink, has ignited discussions regarding unintended electromagnetic radiation leaking into radio frequency bands critical for astronomical observations. Current advancements in satellite technology,
The cosmos continues to astonish us with its intricate structures and phenomena, none more spectacular than the recent discovery surrounding supermassive black holes and their colossal jets. Researchers have identified a particularly striking example known as Porphyrion—a structure so vast that it stretches across an astonishing 7 megaparsecs, or roughly 23 million light-years. This discovery
Mars, renowned for its striking reddish hue and captivating topography, has been a focal point of astronomical inquiry for centuries. Despite extensive exploration and numerous studies, its unusual shape and geological features continue to baffle scientists. A new hypothesis proposed by astronomer Michael Efroimsky from the US Naval Observatory puts forward a compelling theory that
The recent skies above Earth are set to feature an intriguing spectacle: a ‘mini-moon’ named 2024 PT5. This temporary natural satellite, measuring approximately 10 meters (33 feet) in diameter, will grace our orbit for approximately 56.6 days starting from September 29, 2024. However, this brief cosmic encounter is not a first-time event; the asteroid has
The concept that our planet might once have been adorned with a magnificent ring is not just a flight of fancy. Recent scientific investigations suggest that Earth may have hosted a temporary ring structure around 466 million years ago, during the Ordovician period. This intriguing hypothesis is rooted in meticulous detective work conducted by planetary
The recent Polaris Dawn mission, conducted by SpaceX, marked a significant milestone in the realm of commercial space travel. When the quartet of non-government astronauts completed the first spacewalk in history, it not only underscored the rapid advancement of private space ventures but also highlighted the shifting landscape of our approach to exploring the cosmos.
