The cosmic beam was detected by the Tibet AS-gamma Experiment, a collaboration between Japanese and Chinese researchers. Gamma rays are electromagnetic waves with a very short wavelength which are produced during dramatic events in space such as the death of stars in massive supernova explosions. Other electromagnetic waves include radio waves and microwaves. If a strong gamma-ray hit a human, it could kill them or damage their cells and cause cancer. Luckily, Earthlings are protected from gamma rays, which tend to break apart into small particles when they crash into our atmosphere before showering down on Earth, where they can be detected by scientists.

They also placed 64 concrete barrels filled with water which can also detect the gamma-ray remnants. This experiment allowed to detect the power and source of the gamma-ray photons – the name of the tiny, basic particles in light and other forms of electromagnetic radiation including gamma-rays. They were measured at 100 tera-electron volts (TeV)l, which is one trillion electron volts or roughly 10 times the maximum energy recorded by the Large Hadron Collider when it is used to smash particles together. It was calculated that the photons emanated from the Crab Nebula – a cloud of dust and gas left behind when a star went kaboom in a supernova so bright it was observed by Chinese astronomers working in the 11th century AD. Scientists cannot fully explain why the nebula produces such powerful gamma rays, but it’s believed the system is home to a rapidly spinning star called a pulsar, which rotates at high speeds and emit powerful beams of electromagnetic radiation.

China’s Permanent Space Laboratory One Step Closer To Reality

Tiangong-2 to be launched tonight

CHINA will launch its second experimental space laboratory late today, part of a broader plan to have a permanent manned space station in service around 2022.

China will launch its Tiangong-2 space lab from the Jiuquan Satellite Launch Center in northwestern China’s Gobi desert at 10:04pm.

Engineers have begun injecting propellant into the Long March-2F T2 rocket, which will carry Tiangong-2 into space, said Wu Ping, deputy director of the manned space engineering office, yesterday.

“All systems are ready for lift-off,” she said.

“The launch of Tiangong-2 will lay a solid foundation for the building and operation of a permanent space station in the future,” she said.

Once in space, the 8.6-ton Tiangong-2 will maneuver itself into an orbit about 380 kilometers above the Earth for initial on-orbit tests.

It will transfer to a slightly higher orbit about 393 kilometers above the Earth’s surface before the Shenzhou-11 manned spaceship ferries two astronauts into space to dock with the lab.

The two astronauts will work in Tiangong-2 for 30 days before re-entering the Earth’s atmosphere.

In April 2017, China’s first cargo ship, Tianzhou-1, will also be sent into orbit to dock with Tiangong-2 and provide it with fuel and other supplies.

Wu said experts will verify and evaluate key technology involved in on-orbit propellant resupply and equipment repairs as well as that related to long-term stays in space by astronauts.

They will also use the lab, which is designed to operate for at least two years, to conduct space science experiments on a relatively large-scale compared to China’s previous efforts.

Measuring 10.4 meters in length and 3.35 meters in maximum diameter, the Tiangong-2 is much like its predecessor Tiangong-1, which was launched in 2011, but its living quarters and life support facilities have been improved to allow for longer stays by astronauts.

Originally built as a backup for Tiangong-1, it can enable two astronauts to live in space for up to 30 days and is capable of receiving manned and cargo spaceships.

Once inside Tiangong-2, the two astronauts will carry out key experiments related to aerospace medicine, space physics and biology as well as on-orbit equipment repairs in areas such as quantum key transmission, space atomic clock and solar storm research.

More than 40 space science and application experiments will be conducted aboard Tiangong-2.

Its payload includes POLAR, a collaboration between Swiss, Polish and Chinese institutions to study gamma ray bursts.

The space cold atomic clock, which scientists say only loses one second about every 30 million years, is expected to make future mobile navigation more accurate.

Also piggybacking on the Tiangong-2 launch will be a micro satellite that will orbit close to the space lab.

Earlier reports said Tiangong-2 will also carry three experiments designed by the winners of a Hong Kong middle school design contest.

According to Wu, Tiangong-2 is China’s first space lab “in the strict sense.”

In a manned space mission in 2013, three Chinese astronauts spent 15 days in orbit and docked with an experimental space laboratory, the Tiangong 1, or “Heavenly Palace.”

Tiangong-1 was mainly tasked with verifying technology involved in space docking and serving as a platform for a limited number of scientific experiments, Wu said.

Tiangong-1 ended its data service earlier this year.

The manned space engineering office said in March that the orbit of Tiangong-1 will descend gradually over several months until the orbiter eventually burns up in the atmosphere.
