When you look up at the night sky, could something mysterious be looking back?
When you look up at the night sky, could something mysterious be looking back?
Every year on 2nd July, people around the world celebrate World UFO Day — a day to look up at the sky with wonder, ask big questions, and think like a scientist. UFO stands for Unidentified Flying Object. This simply means any object seen in the sky that cannot be easily or immediately identified. It does not automatically mean aliens or spacecraft from another planet! It could be an unusual cloud, a weather balloon, a drone, a meteor, or even a satellite catching the sunlight at a strange angle. The important thing is that science encourages us to investigate, gather evidence, and search for answers rather than jumping to conclusions.
Our universe is incredibly vast and filled with mysteries. Scientists called astronomers study stars, planets, black holes, and galaxies. Other scientists called astrophysicists try to understand the forces and energy that shape the cosmos. Space agencies like NASA in the United States and the European Space Agency send telescopes and probes into space to gather data. In recent years, even governments around the world have released reports about unexplained aerial phenomena — the official scientific term for things seen in the sky that are hard to explain right away. Singapore students can follow these discoveries through science news, space exhibitions at the Science Centre Singapore, and online learning platforms.
World UFO Day is a wonderful reminder that curiosity is the engine of science. Some of the greatest discoveries in human history began with someone asking a simple question: What is that? Why does it do that? How does it work? When you observe something you do not understand, the next step is not to be frightened but to be curious. Write down what you saw, describe it carefully, look for patterns, and seek more information. These are exactly the same skills that scientists, engineers, and astronauts use every single day. In Singapore, where STEM education is highly valued, learning to observe and question the world around you is one of the most powerful skills you can develop.
So this World UFO Day, take a moment to step outside after dark if you can safely do so with an adult, and look up at the sky. Can you spot a star, a planet, or a moving satellite? If you see something you cannot identify, do not panic — get curious! Draw what you see, write down the time and direction, and research what it might be. The universe is around 13.8 billion years old and unimaginably large. There is still so much for scientists — and perhaps you — to discover. Who knows? The next great space discovery might begin with a child in Singapore simply looking up and asking, What is that bright light in the sky?
