BEIJING: Scientists have detected cosmic ray energy readings that would deliver them nearer to proving the existence of dark matter mystery substance believed to comprise 1 / 4 of our universe, a study mentioned Thursday.
Chinese Satellite Closes in on Dark Matter Mystery Check the Reason
Doubtless made up of unknown sub-atomic materials, dark matter mystery is invisible to telescopes and might be perceived solely by way of its gravitational pull on different objects in the universe.

Beijing’s first astronomical satellite launched two years in the past detected 1.5 million cosmic ray electrons and protons, the study mentioned, and unprecedented measurements found curiously low-energy rays.
The team of researchers from China, Switzerland and Italy, who revealed their first ends in the journal Nature, mentioned the info could forged mild on “the annihilation or decay of particle dark matter mystery”.
“This new unseen phenomena can deliver breakthroughs,” Bai Chunli, president of the Chinese Academy of Sciences, mentioned at a briefing.
“After gathering extra knowledge, if we will determine it’s dark matter mystery for certain then that could be very vital. And if not, it’s much more vital as a result of they might be contemporary new particles that nobody had predicted before,” Bai added, to applause from fellow scientists.
The Dark Matter Mystery Particle Explorer (DAMPE) is now gathering extra knowledge from space to assist researchers work out what it may very well be.
DAMPE was launched from the Jiuquan Satellite Launch Centre in the Gobi desert in December 2015, after almost 20 years in growth.
Its designers boast that DAMPE is superior to its US counterpart, the AMS-02 (Alpha Magnetic Spectrometer) that NASA installed on the Worldwide Space Station in 2011.
“Our cosmic ray detection range is 10 times that of AMS-02 and 3 times as correct,” mentioned DAMPE chief scientist Chang Jin.
“Proving the existence of dark matter mystery takes lots of time. Now we have now worked out essentially the most exact spectrum, however we aren’t 100 % sure that this may lead us to the placement of dark matter mystery,” he mentioned.
In keeping with the present state of its devices, DAMPE is expected to record a complete of more than 10 billion cosmic ray events over its helpful lifetime of round three more years.
The project is a collaboration of greater than 100 scientists, students and technicians in China, Switzerland and Italy and funded by the state-backed Chinese Academy of Sciences.
Beijing invests hundreds of billions of in scientific analysis annually, below a five-year plan for 2016 to 2020 that seeks to elevate the country’s technological research capabilities into the world’s top 15.
