The James Webb Space Telescope (JWST) has discovered three massive galaxies, dubbed "red monsters," that challenge current theories of galaxy formation. These galaxies, formed just one billion years after the Big Bang, are far larger and more evolved than expected, suggesting that galaxies may have formed much faster in the early universe than previously thought.
Zoologist Professor Tim Coulson suggests that octopuses, with their remarkable intelligence and adaptability, could potentially become Earth's dominant species if humans were to disappear. Their advanced cognition and problem-solving skills hint at a future where they might develop complex societies, though their lack of physical adaptation for land poses a challenge.
Humanity's exploration of outer space continues to unveil astonishing discoveries that challenge our understanding of the cosmos. From the immense size of the universe, with more stars than grains of sand on Earth, to the bizarre phenomena like cold welding and the existence of a gigantic reservoir of water vapor, space remains a realm of endless wonder and mystery.
The Pentagon's latest UFO report reveals 757 unexplained aerial phenomena sightings in the past year, including a near-collision between a commercial airliner and a cylindrical object off the coast of New York. While many sightings were later identified as ordinary objects, a significant number remain unexplained. Despite investigations, no evidence of extraterrestrial activity has been found.
A new study reveals that extreme weather events, fueled by climate change, are accelerating nitrate contamination of groundwater. Heavy rains following droughts can drive nitrates from fertilizers over 30 feet into the ground in mere days. This rapid percolation poses a significant threat to drinking water, particularly in regions heavily reliant on agricultural fertilizers.
The Pentagon and intelligence officials released their yearly report on UFO sightings, now called UAPs. They investigated over 750 new reports but found no proof of alien life. However, 21 cases remain unexplained, often involving strange shapes like orbs and triangles seen near military areas. While some could be drones, experts are baffled and continue to investigate.
A team of researchers from National Geographic's Pristine Seas team have discovered the world's largest coral colony in the Solomon Islands. The colony, which is larger than a blue whale and estimated to be centuries old, was found in October 2024 and is a testament to the resilience of marine life in the face of climate change.
November's night sky will be illuminated by the Beaver Moon, the final supermoon of 2024. This full moon, appearing larger and brighter than usual, peaks on November 15th. The name originates from beavers' active preparations for winter during this time. Alongside the supermoon, skywatchers can also observe the Pleiades star cluster.
The Indian Institute of Technology Madras (IIT Madras) and the Indian Space Research Organisation (ISRO) have partnered to establish a new Centre of Excellence for Fluid and Thermal Sciences.
