Black holes capture the imagination of scientists and space enthusiasts because they represent the most extreme gravitational forces in the universe. NASA explains that anything approaching a black hole encounters enormous tidal forces that stretch and distort matter, and that time itself slows dramatically due to gravitational time dilation. According to NASA, if an object…
Menstruation in space is a topic that has long been overlooked, yet it is becoming an essential part of astronaut health research as more women travel beyond Earth and missions grow longer. Spaceflight changes how the human body functions. Microgravity affects circulation, fluid movement, bone density, muscle strength, and immune response. These physiological shifts can…
Stunning images of mysterious red lights appearing to fall from space have captured global attention, sparking widespread speculation online. Many social media users suggested these ghostly flashes could be linked to alien signals, but scientists and space agencies have confirmed a more down-to-earth explanation. These striking phenomena are known as red sprites, a rare and…
Comet 3I/ATLAS reveals glowing coma, plasma and dust tails from ESA’s Juice mission/ Image: European Space Agency Harvard astrophysicist Avi Loeb has made a kind of second career out of being the person in the room who refuses to leave “aliens” off the table. With 3I/ATLAS, only the third confirmed interstellar object ever spotted passing…
Sentinel-6B, which was launched on November 17, is the latest satellite in a series of spacecraft used by NASA and its partners to record sea levels since 1992. Their data has aided meteorologists in storm forecasting, infrastructure protection, and coastal community planning.After launch, Sentinel-6B began data cross-calibration with its predecessor, Sentinel-6 Michael Freilich, to give…
NEW DELHI: Former Nasa astronaut Mike Massimino, known for his work on the Hubble Space Telescope and who flew on two space missions, has weighed in on one of humanity’s biggest questions: Are we alone in the universe?The veteran astronaut–who flew on two space missions, conducted four spacewalks, and spent an astonishing 30 hours and…
A Washington study linked sleep above 6.5 hours to cognitive decline Most of us worry about not sleeping enough, the bleary mornings, the heavy eyelids, the sense of running on fumes. What almost no one considers is the opposite problem: the idea that getting too much sleep might quietly work against your brain. It sounds…
With the launch of Sentinel-6B, a new environmental monitoring satellite developed as part of a multibillion-dollar worldwide program, NASA has made a major advancement in its long-term climate monitoring mission. Launched in mid-November atop a SpaceX rocket, the satellite is expected to provide highly precise data on sea-level rise and atmospheric conditions, letting scientists follow…
Doctors warn microsleep is the sleep they fear most, a 1–30 second blackout where your brain stops processing anything, often with your eyes still open. People often imagine danger creeping in when they stay awake too long, the nodding head, the heavy eyes, the drift into sleep they try to fight off. What they don’t…
For centuries, humanity has believed that life and death exist as two fixed states with nothing in between. Either the body functions, breathes and responds, or it stops forever. However, recent scientific discoveries are questioning this long-held view. Several researchers have found evidence that certain cells taken from a dead organism can continue to function…
Scientists’ understanding of Late Cretaceous ecosystems is changing as a result of an amazing finding made in the untamed centre of Bolivia. The biggest known concentration of dinosaur footprints ever discovered is found in a site called Carreras Pampa in Torotoro National Park. There are an astounding 16,600 tracks there, all of which were left…
Observations of the sky recorded thousands of years ago continue to play a remarkable role in modern science, demonstrating that careful human observation has long-lasting value. One particularly significant record comes from ancient China, which documented a total solar eclipse in 709 BCE with remarkable detail. These records include descriptions of the timing and duration…
Source: Earth via X (formerly Twitter) The night of 5 December 2025 offered sky watchers a final lunar spectacle as the full Moon rose into view under a widely recognised seasonal name and a striking orbital alignment. Known traditionally as the Cold Moon, this full Moon coincided with the last supermoon of the year and…
More than 60,000 African penguins vanished from two of South Africa’s most important breeding islands in less than a decade, and scientists say they now understand why. A study published in the journal Ostrich: Journal of African Ornithology has revealed that the collapse of sardine stocks triggered an unprecedented wave of starvation, wiping out more…
Observing the universe has always depended on dark skies, long exposures, and instruments designed to capture signals that are often barely distinguishable from background noise. This delicate balance is beginning to shift as satellite megaconstellations expand across low Earth orbit, increasing both in number and operational complexity. These networks support global communication services, navigation systems,…
ESA’s Jupiter Icy Moons Explorer, or Juice, has recently captured striking new observations of Comet 3I/ATLAS. In November 2025, the spacecraft employed five of its scientific instruments to study the comet, collecting crucial information about its activity, structure, and composition. These measurements are helping scientists understand the behaviour and characteristics of this interstellar visitor. Alongside…
Source: Discover Magazine Recent genetic research has uncovered that ancient humans in southern Africa lived in near-total isolation for almost 100,000 years. This long period of separation led to the development of unique genetic traits that are strikingly different from those found in modern populations. The study, which sequenced genomes from 28 ancient individuals, demonstrates…
Mars Express mission has uncovered a remarkable geological formation on Mars that resembles a butterfly. Situated in the Idaeus Fossae region, this unusual crater has intrigued scientists across the globe, providing valuable insights into the planet’s complex geological history. The butterfly shape was formed by a shallow-angle impact, which caused debris to be ejected in…
The earliest stages of the universe are often envisioned as chaotic, filled with young galaxies that lacked order or recognisable structure. Yet recent high resolution imaging from the James Webb Space Telescope has revealed a galaxy that appears far more mature than expected for its epoch, offering a rare glimpse into the complexity of cosmic…
A small, rarely discussed bacterium has begun reshaping how scientists think about sterility in high security environments. Tersicoccus phoenicis was first detected in spacecraft assembly clean rooms that were engineered to be almost completely free of biological life. These facilities enforce strict contamination controls because any surviving microbe has the potential to hitch a ride…
