|TEHRAN Nike Epic React Flyknit Pearl Pink Womens , June 26 (Xinhua) -- Iran's Supreme Leader Ayatollah Ali Khamenei on Monday called the cause of Palestine as major issue of the Islamic world and urged Muslims to fight Israel with "whatever means possible."
Khamenei made the remarks in an address to a gathering of Iranians in the capital Tehran.
"According to Islamic jurisprudence, when an enemy takes over Muslim lands, Jihad (struggle or fight against enemies of Islam) in any possible form becomes everyone's duty," Khamenei was quoted by Press TV as saying.
"Palestine is the number one issue of the Islamic world, but some Islamic countries are acting in such a way that as if the Palestinian case had been ignored and forgotten," Khamenei said.
"Today the fight against the Zionist regime is obligatory and necessary for Muslims," he said Nike Epic React Flyknit Mens Sale , urging unity among the Muslim states.
"Division and discord are harmful to Islam and the Islamic Ummah (nation)," he stressed.
Khamenei also hailed Al-Quds Day rallies on Friday and the massive turnout in the capital Tehran and other cities across Iran to support the Palestinian people.
On Friday, the ralliers chanted anti-Israel and anti-U.S. slogans and carried banners condemning Israel's continued occupation of Palestinian lands.

BEIJING, Nov. 30 (Xinhua) -- China's Dark Matter Particle Explorer (DAMPE) has detected unexpected and mysterious signals in its measurement of high-energy cosmic rays, which might bring scientists a step closer to shedding light on invisible dark matter.
The satellite, also called Wukong, or Monkey King Nike Epic React Flyknit Mens , has measured more than 3.5 billion cosmic ray particles with the highest energy up to 100 tera-electron-volts (TeV for short, corresponding to 1 trillion times the energy of visible light), including 20 million electrons and positrons, with unprecedentedly high energy resolution.
"DAMPE has opened a new window for observing the high-energy universe, unveiling new physical phenomena beyond our current understanding," said Chang Jin, chief scientist of DAMPE and vice director of the Purple Mountain Observatory of the Chinese Academy of Sciences (CAS).
The initial detection results were published in the latest issue of the academic journal Cheap Nike Epic React Flyknit Womens , Nature.
"This is the first time a space experiment has reported a detailed and precise electron and positron spectrum up to about 5 TeV. In this energy range, we found some unexpected and interesting features. We have detected a spectral break at 0.9 TeV and a possible spike at 1.4 TeV," said Chang.
Precise measurement of cosmic rays, especially at the very high energy range, is important for scientists to look for traces of dark matter annihilation or decay, as well as to understand the most energetic astrophysical phenomena in the universe, such as pulsars Nike Epic React Flyknit Womens Sale , active galaxy nuclei and supernova explosions. "Our data may inspire some new ideas in particle physics and astrophysics," said Chang.

Dark matter, which cannot 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 Cheap Nike Epic React Flyknit Black Womens , accounts for only about 5 percent of the universe. However, about 26.8 percent of the universe is dark matter and 68.3 percent dark energy.
China sent DAMPE into an orbit of about 500 kilometers above the earth on December 17, 2015, to look for evidence of the annihilation or decay of dark matter particles in space.
DAMPE has the widest energy range coverage and the highest energy resolution of all the dark matter probes currently in space. Based on the satellite's data, scientists drew the cosmic ray electron and positron spectrum.
To their surprise, scientists found a break at around 0.9 TeV and a strange spike at around 1.4 TeV on the spectrum. "We never expected such signals," Chang said.
"The spike might indicate that there exists a kind of unknown particle with a mass of about 1.4 TeV Nike Epic React Flyknit Black Womens Sale ," said Chang.

"All the 61 elementary particles predicted by the standard model of particle physics have been found. Dark matter particles are beyond the list. So if we find a new elementary particle, it will be a breakthrough in physics Nike Epic React Flyknit Black Womens ," he added.
"The spike is very unusual," said Fan Yizhong, deputy chief designer of the scientific application system of DAMPE. "The signals might have originated from either dark matter or pulsars. Even if they were from puls.
