Physicists propose a mirror-image antimatter universe extending backward in time before the Big Bang. Key Takeaways: Scientists suggest our universe has a mirror-image “antiuniverse” that existed before the Big Bang. This antiuniverse, filled with antimatter, obeys a fundamental physics rule called CPT symmetry. The theory offers a natural explanation for dark matter, linking it to…

Hyperion is a colossal proto-supercluster, over 1 million billion times the mass of the Sun. Key Takeaways: Astronomers discovered Hyperion, the earliest known proto-supercluster, just 2 billion years after the Big Bang. This massive structure is over 1 million billion times the Sun’s mass, rivaling today’s largest clusters. Hyperion’s vast network of galaxies is mapped…

PSR J1748-2446 spins 716 times per second—so fast, it nearly tears itself apart. Key Takeaways: PSR J1748-2446 is the fastest-spinning neutron star ever discovered, rotating 716 times per second. It’s an extreme example of a neutron star—denser than lead by 50 trillion times and harder than a diamond. Its intense gravity flattens anything on its…

Astronomers have detected at least 70 rogue planets—worlds that wander the galaxy alone. Key Takeaways: At least 70 free-floating planets have been discovered, making it the largest known group. These planets don’t orbit a star and travel freely through space. Rogue planets are difficult to detect because they emit little to no light. Scientists analyzed…

Earth’s radio signals have only reached about 15,000 stars—barely a blip in the Milky Way. Key Takeaways: Aliens might ignore planets with just life and look for technological signals instead. Earth’s radio waves have only reached a tiny portion of the Milky Way. Only civilizations within 50 light-years could have had time to respond. Early…

Phobos’ surface reflects light like a comet’s—hinting that Mars’ moon may have cosmic origins. Key Takeaways: Newly analyzed photos reveal that Phobos shares key reflective properties with Jupiter-family comets. High-resolution ESA photos, previously unpublished, show that Phobos’ surface behaves much like Comet 67P. Scientists suggest Mars’ moons could have once been a single bilobed comet…

The Oort Cloud is so vast that its outer edge may extend halfway to Proxima Centauri. Key Takeaways The Oort Cloud is a massive, spherical shell of icy objects surrounding our Solar System. It contains trillions of icy bodies and stretches from 2,000 to 200,000 AU from the Sun. Long-period comets originate from the Oort…

Astronomers directly imaged two giant exoplanets orbiting a young sunlike star 300 light-years away. Key Takeaways For the first time, astronomers have directly photographed multiple planets around a sunlike star. The European Southern Observatory’s VLT captured this rare cosmic snapshot using advanced imaging technology. The two gas giants, TYC 8998-760-1b and TYC 8998-760-1c, are much…

The UK’s first Flat Earth Convention drew global speakers and debated science, power, and knowledge. Key Takeaways A scientist attended a three-day Flat Earth Convention in the UK to understand their perspectives. Flat earthers emphasize scientific methods but distrust mainstream scientific institutions and experts. Many attendees believe knowledge is controlled by those in power, echoing…

The first photo of Earth from space was taken in 1946—years before the first satellite! 5 Key Takeaways The first-ever space photo was captured on October 24, 1946, from a V-2 missile at 65 miles above Earth. This achievement marked the beginning of space photography, paving the way for modern satellite imaging. Before this, in…
