NASAs Europa Clipper, the largest spacecraft designed for a planetary mission, was recently moved to the SpaceX hangar at Launch Complex 39A in anticipation of its launch.
The spacecraft, encapsulated within payload fairings for protection, is set to be mounted on a SpaceX Falcon Heavy rocket.

A recent study suggests that by the Neoproterozoic period, distinct lineages of amoebae, as well as the ancestors of plants, algae, and animals, had already emerged and managed to survive the two global glaciations that covered the planet.
Approximately 800 million years ago (mya), long before the formation of the supercontinent Pangea, Earth’s biodiversity was more varied than previously thought. Brazilian researchers, through the reconstruction of the evolutionary tree of life from ancient amoebas and the ancestors of algae, fungi, plants, and animals, have proposed a scenario where multiple distinct lineages of species coexisted during this era. Their findings are detailed in an article published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).
According to the literature, several lineages of eukaryotes that first emerged 1.5 billion years ago diversified and established themselves during the Neoproterozoic oxygenation event (850−540 mya), when oxygen levels in the atmosphere and oceans rose significantly owing to changes in the planet’s geochemistry.
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle’s observations two millennia ago and modern-day understanding, while opening the door to a whole host of “cool”—and “cooling”—implications.
While various studies have hinted at the existence of dark matter, its nature, composition and underlying physics remain poorly understood.
In fusion experiments, understanding the behavior of the plasma, especially the ion temperature and rotation velocity, is essential. These two parameters play a critical role in the stability and performance of the plasma, making them vital for advancing fusion technology. However, quickly and accurately measuring these values has been a major technical challenge in operating fusion reactors at optimal levels.
The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable than others. These nuclei had specific numbers of protons or neutrons, or magic numbers, as physicist Eugene Wigner called them.
ESA’s first planetary defence spacecraft has departed planet Earth. The Hera mission is headed to a unique target among the more than 1.3 million known asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering mysteries associated with its deflection.
By sharpening scientific understanding of the ‘kinetic impact’ technique of asteroid deflection, Hera aims to make Earth safer. The mission is part of a broader ambition to turn terrestrial asteroid impacts into a fully avoidable class of natural disaster.
Developed as part of ESA’s Space Safety programme and sharing technological heritage with the Agency’s Rosetta comet hunter, Hera lifted off on a SpaceX Falcon 9 from Cape Canaveral Space Force Station in Florida, USA, on 7 October at 10:52 local time (16:52 CEST, 14:52 UTC) with its solar arrays deploying about one hour later.

Dr. Isaac Asimov was a prolific science fiction author, biochemist, and professor. This was recorded in 1982. Asimov was best known for his works of science fiction and for his popular science essays. Born in Russia in 1920 and brought to the United States by his family as a young child, he went on to become one of the most influential figures in the world of speculative fiction. He wrote hundreds of books on a variety of topics, but he’s especially remembered for series like the \.
