Have scientists found an active triple black hole system in a galaxy merger; know the truth
Astronomers have discovered a rare cosmic event: three supermassive black holes, each at the heart of a merging galaxy, are actively feeding and emitting radio waves. This unprecedented observation confirms theoretical models of triple black hole systems and provides a real-world example of multiple black holes consuming matter simultaneously, a phenomenon previously unseen in such detail.
NASA's Hubble Telescope has revealed that planetary systems experience violent collisions for much longer than previously thought. Observations of the Fomalhaut system, 25 light-years away, show recent, massive impacts between planetesimals, challenging existing models of planetary formation and dynamics. These events, once believed to be rare, are now seen as crucial for shaping planetary development.
Why this Indian river turns red during the monsoon
India's rivers transform annually during the monsoon season. Heavy rainfall increases river flow, stirring up sediment. Iron-rich soil particles are carried into the water, giving it a red hue. This natural process is linked to climate and geographical features. The intensity of the monsoon directly impacts the river's color. This annual event highlights India's dynamic natural cycles.
From foot to head: How Chinese doctors kept a severed ear alive; reattached it months later
In a remarkable feat of reconstructive surgery, Chinese doctors successfully grafted a woman's severed ear onto her foot to preserve it. After a severe workplace accident, the ear was reattached to her head following extensive scalp reconstruction. This innovative procedure highlights China's history of pioneering, unconventional medical interventions for severe injuries.
Did humans domesticate wolves 5000 years ago? Scientists find supporting evidence
Ancient wolf remains unearthed on a Baltic island suggest a complex relationship with humans 5,000 years ago. These wolves, brought to the island by people, shared diets and showed signs of care, hinting at a bond beyond mere coexistence. Genetic analysis reveals they weren't ancestors of modern dogs, raising new questions about early human-canid interactions.
What is the colour of water, and why does it look clear in a glass but blue in the sea
Water's colour, often unseen in small amounts, reveals itself in larger bodies like the sea. Scientists explain that water absorbs red light more than blue, a phenomenon noticeable only with significant depth. Particles, algae, and even sky reflection further influence the hues we perceive, turning clear water into a vibrant spectacle.

Lunar Nuclear Power Race: Russia plans plant on Moon by 2036; US eyes 2030 deadline
Insect Use In Moon And Mars Habitats: NASA explores ecosystem support; closed-loop life systems eyed
NASA is exploring the use of insects for future space missions. These small creatures can help pollinate crops, process waste, and maintain soil health on the Moon and Mars. Their ability to thrive in controlled environments with gravity offers a sustainable solution for long-term human survival beyond Earth. This biological approach complements technological advancements for space exploration.
A 15,600-year-old human footprint in Chile may rewrite the story of the first Americans
A 15,600-year-old human footprint discovered in southern Chile is now believed to be the earliest confirmed sign of human presence in South America. This discovery, made near Osorno, predates the previously accepted earliest settlement by about a thousand years, potentially altering migration timelines.
Black Moon Explained For Stargazers: Rare new moon patterns aid astronomy; 2026 dates for India
Skywatchers, take note! A 'black moon,' a rare lunar timing event, occurs when there are two new moons in a single month or the third new moon in a four-new-moon season. While invisible, these nights offer the darkest skies, perfect for stargazing and astrophotography. Plan your celestial observations for 2026 with our new moon calendar, featuring IST times.
Dolphins arent cute : GoPro footage shows brutal, unsettling reality of how they hunt
Dolphins are often cast as playful, gentle creatures, but footage from GoPros attached to six wild bottlenose dolphins tells a different story. Trained by the US Navy, the animals were filmed hunting with precision, using sonar clicks, suction feeding and audible victory squeals as they consumed hundreds of fish, and even venomous sea snakes, revealing a far more primal side to their behaviour.
This asteroid might hit moon: Scientists track asteroid 2024 YR4
Astronomers are closely watching asteroid 2024 YR4. This space rock may hit the Moon in December 2032. The impact could be visible from Earth. It could also send debris towards Earth. This poses a risk to satellites and future human missions. The James Webb Space Telescope will provide more data. Scientists are monitoring the skies for safety.
Loud alien signals may be humanitys first clue to extraterrestrial life
Scientists may soon detect alien life. Astronomer David Kipping suggests initial signals will be loud and unusual. This is because the first detected civilizations might be in decline. Past astronomical discoveries show extreme examples are found first. This could mean humanity receives warnings about advanced societies facing problems. The search for alien life might reveal much about our own future.
