Scientist Claims Mysterious Interstellar Comet Could Be Alien Technology.Here's What We Know
Measuring over 12 miles in width and traveling at a speed of 37 miles per second relative to the Sun, 3I/ATLAS is expected to pass within 130 million miles of Earth on October 30, 2025. Initial observations led astronomers to believe it was an asteroid, but follow-up studies confirmed it as a comet of interstellar origin.
However, a new paper co-authored by Harvard University astrophysicist Avi Loeb has introduced a provocative theory: What if 3I/ATLAS is not just a natural object, but an example of alien technology?
Loeb, a well-known figure in the scientific community for his bold ideas about extraterrestrial life, leads the Galileo Project-a scientific initiative to search for alien technology. In the new paper, uploaded to the preprint server arXiv on July 16, Loeb and his colleagues analyze the comet's unusual speed and trajectory. The paper has not been peer-reviewed and is described by Loeb as a theoretical "pedagogical exercise."
While the majority of scientists believe 3I/ATLAS is a typical icy comet, Loeb's suggestion encourages researchers to keep an open mind. He emphasized in a blog post that the idea is meant to inspire curiosity and scientific exploration, not confirm alien presence.

Moon tonight shines at 69 percent brightness as Waxing Gibbous phase illuminates the sky
TIL Creatives The Moon is in its Waxing Gibbous phase tonight, with 69 percent of its surface illuminated, offering stunning views of craters and lunar seas as it moves closer to next week's full moon Skywatchers across the United States can expect a dazzling display in tonight's sky as the Moon enters a Waxing Gibbous phase, lighting up 69 percent of its surface, according to NASA's Daily Moon Observation. The glowing lunar disk is steadily building toward the next full moon, expected on August 9. Moon tonight(August 3) marks day 10 of the lunar cycle, part of the Moon's ongoing 29.5-day journey around Earth. These cycles, new moon to full moon and back again, are created by the Sun's light reflecting off different portions of the Moon's surface as it orbits Earth. It's a rhythm that has guided humanity for millennia. The Waxing Gibbous moon is more than halfway lit but not yet full. As it rises in the eastern sky just before sunset and sets shortly after midnight, it creates an excellent opportunity for both casual stargazers and astronomy enthusiasts. Even without any equipment, you can spot major features like the Copernicus Crater, Mare Fecunditatis, and Mare Crisium. Binoculars will reveal the Alphonsus Crater, Posidonius Crater, and Mare Frigoris. Those with telescopes can explore the Rima Ariadaeus, the Descartes Highlands, and the Fra Mauro Highlands, where Apollo 14 once landed. According to NASA, there are eight primary phases of the Moon: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous (tonight's phase), Full Moon, Waning Gibbous, Last Quarter, and Waning always see the same side of the Moon, but the amount illuminated changes as it orbits Earth. That shifting glow creates the lunar phases we observe each night.

Seeds of seabuckthorn, Himalayan buckwheat part of experiment on ISS
Reuters NASA's SpaceX Crew-11 crew members (File photo) Seeds of seabuckthorn and buckwheat grown in the cold desert of Ladakh are part of the experiments on board the International Space Station flown by NASA's Crew-11 mission. Seeds procured from 11 nations across five continents are part of the study spearheaded by US-based bioastronautics firm Jaguar Space, which plans to expose the seeds to microgravity conditions for a week. The seeds are part of the "Emerging Space Nation's Space for Agriculture & Agriculture for Space" payload that flew to the ISS along with NASA's Crew-11, which lifted off from Florida on Friday and docked onto the orbital lab on seeds will be brought back by the Crew-10, which is expected to return to Earth later this month. The seeds grown in Ladakh were sourced by Bengaluru-based space start-up Protoplanet. "We will study how the seeds react to micro-gravity conditions and their potential use as a food source for long-duration space missions," Siddharth Pandey, Director, Protoplanet, told stated that Protoplanet has contributed sea buckthorn and Himalayan tartary, nutrient-rich plants native to high-altitude regions. The Himalayan tartary is a variety of buckwheat that is nutrient-rich and return from space, the seeds will be studied by Indian to Jaguar Space, the World Seeds study examines how seeds react to the unique stresses of the space environment before they begin to grow, focusing on fundamental processes such as the activation of genes and metabolic pathways essential for germination. This experiment explores the potential of previously unexamined species to contribute to future space agriculture initiatives. Seeds from the Maldives, Argentina, Brazil, Costa Rica, Guatemala, Nigeria, Armenia, Egypt, Pakistan and Nigeria are part of the experiment. "Beyond its scientific potential to advance research on climate resilience and global food security, the World Seeds payload represents a meaningful step toward ensuring that, as humanity becomes a spacefaring civilization, the millennia-old knowledge, biodiversity, and cultural heritage of communities around the world are carried forward as an essential part of that journey," said Dr Luis Zea, Founder of Jaguar Space.
