Scientists believe early Earth was not green, it may have been purple: Know how scientists believe it’s possible |

[ad_1] Source: NASA Astrobiology Beginning two billion years of Earth’s history, the amount of oxygen was not sufficient, but rich in carbon dioxide and methane. The early forms have been able to generate metabolic energy from sunlight using the ‘purple’ pigment, predating the evolution of chlorophyll and photosynthesis. The pigment called retinal, if evolved, could […]

One million AI satellites to orbit Earth? SpaceX’s mind-blowing plan of data centers in outer space explained

[ad_1] SpaceX Wants a Million Satellites for AI: Is This the Future of Computing or a Space Disaster Waiting to Happen? SpaceX has submitted a daring proposal to the US Federal Communications Commission (FCC) to launch a constellation of up to one million satellites into Earth orbit, not for Internet coverage like Starlink but as […]

Will Earth lose gravity in 2026? Viral ‘Project Anchor’ claim sparks panic, NASA responds |

[ad_1] Will Earth Lose Gravity in 2026? Viral Claim Sparks Panic, NASA Responds/ AI rendered Image A viral claim warning of catastrophic consequences if Earth were to “lose gravity” for seven seconds in August 2026 has spread rapidly across social media, drawing millions of views and fuelling speculation about hidden NASA projects and impending global […]

This lake is the ‘most nuked location on Earth’ and still remains dangerously radioactive; know why | World News

[ad_1] Source: National Geographic Where some cities fade away with time, others are deliberately erased and destroyed. Deep within Central Asia, a chilling symbol of Cold War-era secrecy has long been concealed: a region made inconspicuous on maps after it was transformed into the most nuclear-bombarded spot on earth. Hidden away for so long as […]

This ocean near Panama is dying, and same thing might happen all over earth | World News

[ad_1] This ocean near Panama is dying, and same thing might happen all over earth. AI-generated Something unusual happened off the coast of Panama this year, and at first it did not look dramatic. There was no single storm, no sudden die-off washing ashore. Instead, there was an absence. The water stayed warm when it […]

Scientists say a space explosion 13,000 years ago may have changed life on Earth |

[ad_1] For a long time, the end of the Ice Age felt like a slow fading rather than a sharp break. Mammoths vanished. Old ways of living disappeared. The climate lurched colder again, without much warning. Archaeologists and geologists have argued over the cause for decades. Some blamed hunting. Others pointed to natural climate shifts. […]

How can we reduce CO2?

[ad_1] Carbon dioxide is vital to all life on Earth. Without it, plants wouldn’t be able to grow and produce the oxygen we breathe. Yet an excess of CO2 is posing a real threat to the livability of the planet. As a greenhouse gas it traps heat in the Earth’s atmosphere and CO2 levels have […]

NASA captures record-breaking images of the fastest-spinning asteroid in space |

[ad_1] NASA has released a set of extraordinary radar images showing an asteroid spinning so fast that it has forced scientists to rethink long-held assumptions about small bodies in space. The asteroid, known as 2025 OW, is tiny compared to the large space rocks we normally hear about, yet its behaviour is anything but ordinary. […]

How was the first full-colour photograph of Earth captured by NASA |

[ad_1] The first full-colour photograph of Earth marked a turning point in how humanity understood its planet, shifting the view from fragmented satellite snapshots to a vivid global portrait. During the late 1960s, NASA was expanding its experimental satellite programme, exploring how colour imaging could enhance weather forecasting and planetary observation. This period saw rapid […]

How ESA plans to make astronaut food from thin air for Moon and Mars missions |

[ad_1] Long-duration space missions to the Moon or Mars present one of humanity’s greatest scientific and logistical challenges: how to ensure astronauts receive a sustainable and nutritious food supply without relying on resupply missions from Earth. Traditional storage-based solutions are not viable for journeys spanning years, while cultivating food in microgravity has yet to prove […]
