China launched satellite in search for Dark Matter

Beijing: China on Thursday launched its first Dark Matter Particle Explorer (DAMPE) satellite in a fresh search for smoking-gun signals of the invisible material that scientists believe makes up most of the universe’s mass.

The DAMPE satellite, nicknamed “Wukong” after the Monkey King with penetrating eyes in the Chinese classical fiction “Journey to the West”, blasted off on Thursday morning on a Long March 2-D rocket from the Jiuquan Satellite Launch Centre in Gansu province, Xinhua news agency reported.

It will enter a sun-synchronous orbit at a height of 500 km to observe the direction, energy and electric charge of high-energy particles in space.

From there, scientists hope the 1.9-tonne desk-sized satellite could help raise the “invisible cloak” on the dark matter and shine more light on the hypothetical mass.

With the new DAMPE satellite, scientists will look for evidence of dark matter annihilation or decay.

Wukong will scan the space in all directions in the first two years and focus on sections where dark matter are most likely to be observed afterwards.

More than 100 scientists will study the data sent back by Wukong. Initial findings are expected to be published in the second half of 2016.

Dark matter, which does not emit or reflect enough electromagnetic radiation to be observed directly, is one of the huge mysteries of modern science.

Theorised by scientists who could not understand missing mass and strangely bent light in faraway galaxies, dark matter has become widely accepted in the physics community even though its existence has never been concretely proven.

Scientists now believe only around five percent of the total mass-energy of the known universe are made up of ordinary matter, whereas dark matter and dark energy make up the rest.

Knowing more about dark matter could hence give humanity a clearer idea about the past as well as future of galaxies and the universe, and will be revolutionary for the world of physics and space science. (IANS), (image courtesy: space.com)

China hopes to welcome the United States “back to the negotiating table” to discuss global efforts to limit climate change at a United Nations summit to be hosted by Chile in December, its top climate change envoy said on Tuesday.

Xie Zhenhua, China’s Special Representative for Climate Change Affairs, told journalists during a visit to a solar energy plant outside the Chilean capital Santiago that China would provide “full support to the Chilean presidency of this meeting.”

The summit was “strong proof that a multilateral negotiation process is successful, that multilateralism is working,” he said.

Asked if the U.S. approach to the threat of climate change under President Donald Trump and the U.S.-China trade dispute might affect the outcome in Santiago, Xie replied: “China and the U.S. has many differences but we do have some common grounds on climate change issues as well and we welcome them back to the negotiating table on climate change, we are very open to that.”

Trump has signaled his intention to withdraw the United States from the 2015 Paris climate accord and been dismissive of regulations aimed at slashing greenhouse gas emissions. He has also expressed his preference for bilateral trade pacts over multilateral agreements.

In July, China pledged on the sidelines of the G20 summit in Osaka to show “the highest possible ambition” in the fight against climate change. Experts and policy advisors say the world’s biggest greenhouse gas emitter could introduce new and more stringent carbon targets next year.

Xie said China would back a bid by the U.N. secretary-general and climate change envoy to persuade all countries to update their Nationally Determined Contributions (NDC) goals to keep global warming to well below two degrees centigrade.

“The most important objective is to identify the new NDCs for the post-2020 period and link those new NDCs together with the financial support from the developed countries as promised,” Xie said. “To have that financial support in place is very important and that’s the objective we would like to achieve.”
