2025年的史詩級發現：恐龍足跡、火焰起源和行星遊行揭曉！

The year 2025 was full of incredible scientific discoveries that gave us new insights into our planet, our history, and even the universe. One of the most fascinating finds happened in Oxfordshire, where a quarry revealed one of the largest dinosaur trackway sites ever found. Scientists uncovered around 200 huge footprints that were left by dinosaurs 166 million years ago. These tracks belonged to two very different dinosaurs: a long-necked plant-eater called Cetiosaurus and a two-legged meat-eater known as Megalosaurus. Some of the tracks stretched for up to 150 meters, and researchers believe there could be even more hidden beneath the ground, waiting to be discovered.

Another major breakthrough came from an archaeological site in Barnham, Suffolk. Here, researchers found evidence that humans were making fire as far back as 400,000 years ago. This pushes back the timeline for fire-making by more than 350,000 years. The ability to create fire was a huge step for early humans. It allowed them to cook food, stay warm, and gather together in groups. Fire also helped their brains grow and made it possible for them to think, plan, and invent new things. This discovery shows just how important fire was in shaping human evolution.

Scientists also studied how humans form relationships compared to other animals. They found that about 66 percent of humans form monogamous bonds, meaning they stay with one partner for a long time. This is higher than chimpanzees and gorillas, but not as high as the California deermouse, which is completely monogamous. The study shows that while humans are not the most loyal creatures in the animal kingdom, our tendency to form lasting relationships is still impressive.

In the world of astronomy, 2025 brought a rare event called a planetary parade. For a few evenings in February, seven planets—Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn—were visible in the evening sky at the same time. Four of these planets could be seen without a telescope, while the others needed special equipment. Scientists say that such a clear and well-timed planetary parade will not happen again until 2040, making this a special moment for skywatchers.

There were also exciting developments in space science. For the first time in nearly 50 years, samples of Moon dust arrived in the UK. These tiny grains of lunar dust are extremely valuable for scientists because they can help us learn more about how the Moon was formed and how it has changed over time. The dust is kept in a high-security facility to prevent contamination, and only a few scientists are allowed to study it.

Another surprising discovery came from the forests of Uganda, where wild chimpanzees were filmed using plants to treat their wounds. Researchers from the University of Oxford, working with local teams, observed chimpanzees applying plant material to their own injuries and even to the injuries of other chimpanzees. This behavior suggests that chimpanzees have a deep understanding of natural remedies and know how to use plants as medicine.

All these discoveries from 2025 show how science continues to reveal the wonders of our world and our past. Whether it is finding ancient dinosaur footprints, learning about the origins of fire, or watching chimpanzees use plants as medicine, each discovery helps us understand more about ourselves and the world we live in.
