The future of astronaut meals may soon involve a surprising ingredient: insects. As NASA plans longer missions to the Moon and Mars, researchers are exploring food sources that are compact, nutritious and sustainable. According to a NASA study on aquatic invertebrate protein sources for long-duration space travel, insects such as mealworms and crickets could provide…

Astronomers have detected the first-ever radio signal from the interstellar object 3I/ATLAS, marking a milestone in the study of visitors from beyond our solar system. The finding, made using South Africa’s MeerKAT radio telescope, confirms that the mysterious object is a natural comet, not an alien probe as some had speculated. Scientists say the discovery…

On a November night when most of the world was busy doomscrolling, the heavens scrolled back. Curtains of pink and green light unfurled above the plains, over mountains and strip malls, over the tired suburbs of Tennessee and the endless highways of New Mexico. For a brief moment, even Alabama looked like Iceland. The northern…

Woodpeckers are remarkable examples of natural engineering, capable of delivering rapid, powerful pecks to drill into trees, find insects, and communicate, all without causing self-injury. Although it seems as if they simply strike with their heads, a study published in the Journal of Experimental Biology shows a far more intricate system at work. The bird…

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 efficient…

It’s that time of the year when India’s east coast braces for cyclones that pose a threat to lives and livelihoods. But are cyclones all that bad? A new study shows these extreme weather systems can have an environmental benefit: carbon sequestration.The Indian Ocean absorbs about 190 million tonnes of carbon every year. The study…

Blue Origin has postponed the much-anticipated launch of its New Glenn rocket carrying NASA’s twin ESCAPADE probes to Mars. Originally scheduled for Sunday, 9 November 2025, the launch was called off due to unfavourable weather conditions at Cape Canaveral’s Launch Complex 36. This delay comes just one day before new federal restrictions for commercial spaceflights…

It may seem surprising to ask which country is closest to space, since no part of Earth’s surface crosses the boundary into the atmosphere beyond. Yet from a scientific standpoint, one location can be identified as physically nearer to outer space than any other. This has nothing to do with national borders or sea-level elevation…

A remarkable new image of interstellar comet 3I/ATLAS has reignited global fascination among astronomers and space enthusiasts alike. As reported, the image is captured by British astronomers Michael Buechner and Frank Niebling. The photograph reveals intricate jet structures streaming from the comet in multiple directions, offering an unprecedented glimpse into its dynamic behaviour as claimed.Taken…

Source: Royal Society Open Science Beneath the waves off Japan’s Pacific coast, scientists have made a discovery that seems straight out of a nature documentary: a pale pink sea anemone that actually builds homes for hermit crabs. Named Paracalliactis tsukisome, this elegant creature isn’t just another deep-sea oddity; it’s a living architect of the ocean…
