Using the Five-hundred-meter Aperture Spherical Radio Telescope, or the "China Sky Eye," a team of Chinese astronomers built the largest-ever high-quality catalog of neutral hydrogen (HI) sources beyond our Galaxy.
Hydrogen, the most abundant element in the universe, is a key component of galaxies. Within disk galaxies, the HI is a significant component of the interstellar medium.

Peat bogs in the tropics store vast amounts of carbon, but logging, plantations, road building, and other activities have destroyed large swaths of these ecosystems in places like Indonesia and Malaysia. Peat formations are essentially permanently flooded forestland, where dead leaves and branches accumulate because the water table prevents their decomposition.

When Chang'e-3 became the first Chinese craft to land on the Moon 10 years ago, it kicked off nationwide celebrations - and a decade of major successes for a rapidly accelerating space programme.
Since the December 14, 2013 landing, China has built a crewed space station, sent a robotic rover to Mars and become the first nation to make a controlled landing on the far side of the Moon.
