介绍:
China’s Dark Matter Particle Explorer (DAMPE) has detected mysterious signals, which might bring scientists a step closer to shedding light on invisible dark matter. DAMPE, also called Wukong, is a satellite designed to observe the direction, energy and electric charge of high-energy particles in space in search of dark matter.
Dark matter, which can’t be seen or touched, is one of the great mysteries of science. Scientists calculate that normal matter, such as galaxies, stars, trees, rocks and atoms, accounts for only about 5% of the universe. However, about 26.8% of the universe is dark matter and about 68.3% is dark energy. Everything we know is really a tiny part of reality.
DAMPE was sent into an orbit of about 500 kilometers above the earth in 2015. As China’s first ever space observatory, it has measured more than 3.5 billion cosmic ray particles.
You may wonder why exploring dark matter is important. Scientists believe that exploring dark matter will bring breakthroughs in technological development. Only when we understand the nature of dark matter can we find how it will change the future.
