How far have Earths radio signals really travelled into space
Earth's radio bubble, a century-old expansion of broadcast signals, now spans over 119 light-years. While these waves have reached nearby stars like Proxima Centauri, they are too faint and blended with cosmic noise for any civilization to decipher. Modern communication methods are also reducing the energy leaked into space, making Earth quieter.
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.
A hidden Arctic world: Methane mounds and life found 3.6 km below the Greenland Sea
Scientists have found a unique geological and biological complex deep in the Greenland Sea. Methane hydrate mounds, formed by trapped methane and ice, were discovered along the Molloy Ridge. These mounds support chemosynthetic organisms, life that thrives without sunlight. This discovery offers new insights into Arctic oceanography and methane stability.

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.
