BEIJING, May 29 (Xinhua) -- China's new space telescope to be launched soon will probe many mysteries of the universe, including the belching "big eaters" -- active galactic nuclei at the most remote edges of the universe.

Scientists have discovered that almost every galaxy has a supermassive black hole with a mass several million to several billion times that of the Sun at its center. With their mighty gravitational attraction Air Max 95 Womens Sale , the supermassive black holes engulf the surrounding gas and dust.

When a black hole swallows too much, the excess matter is converted into two jet-flows perpendicular to the accretion disk of the black hole, which is like a glutton with a bloated belly belching.

The jet-flows and accretion disk of the supermassive black hole generate X-ray radiation strong enough to travel billions of light years. These galaxies have very bright nuclei -- so bright the central region can be more luminous than the remaining galaxy. Scientists call them active galactic nuclei.

The Hard X-ray Modulation Telescope (HXMT), developed by Chinese scientists, will observe some active galactic nuclei.

"Since the active galactic nuclei are very far from the Earth Air Max 90 Womens Sale , our telescope can only detect the brightest ones," says Zhang Shuangnan, lead scientist of HXMT and director of the Key Laboratory of Particle Astrophysics at the Chinese Academy of Sciences (CAS).

The big eaters are full of mysteries. Scientists have found the double jet phenomenon is very common in galaxies with active galactic nuclei, but they don't understand why supermassive black holes cannot engulf all the matter falling into them.

Supermassive black holes are very different from black holes of stellar mass, which are formed when very massive stars collapse at the end of their life cycles. Scientists are still not clear how supermassive black holes are formed and grow Air Max Womens Sale , which is a key to understanding the evolution of galaxies.

HXMT's observation is expected to help scientists see the core region close to the event horizon of supermassive black holes at the center of active galaxies and gather information about the extremely strong gravitational fields, Zhang says.

MOSCOW, July 10 (Xinhua) -- Russia and the United States will continue cooperation in Syria on the basis of a trilateral agreement with Jordan on setting up a de-escalation zone in the war-torn country, Russian Foreign Minister Sergei Lavrov said Monday.

"Although yesterday Nike Air Max 95 Sale , from 12 p.m. Syrian time, the regime of ceasefire became effective, it has to be strengthened, so there will be plenty of work to be done there," Lavrov told a press conference.

On Friday Nike Air Max 90 Sale , Russia, the United States and Jordan reached a deal to support a ceasefire in southwest Syria, setting up a de-escalation zone to create appropriate environment for reaching a political solution to the situation in the Middle East country.

Lavrov said the agreement envisages the elaboration of additional details on the practical functioning of the zone.

To coordinate those details, it was agreed to put into operation a monitoring center, which is being created by Russia Nike Air Max Sale , the United States and Jordan in the Jordanian capital of Amman, and which will be in permanent contact with the Syrian government forces and the opposition, he said.

According to Lavrov, the participants in the talks on Syria in the Kazakh capital of Astana were close to reaching an agreement on setting up two more de-escalation zones in the western Syrian region of Homs and in the eastern region of Ghouta, and talks were continuing on another zone in the northwestern governorate of Idlib.

Lavrov said Russia saluted "active participation" of the United States in the Astana process and would keep cheering it Air Max 95 Sale , in spite of Washington's observer status at the talks.

He added that Moscow also maintained stable contacts with Washington at the talks in Geneva, which were restarting on Monday, as well as with other key countries, which influenced the developments in Syria.

"We have to consider attitudes of a very big number of players when referring to its solution, and it is not easy to reconcile those positions and to find the balance of interests. But as the Russia-U.S.-Jordan agreement of July 7 has shown Air Max 90 Sale , it is possible," Lavrov said.

The Syrian war, now into its seventh year, has taken a toll on the country's population with hundreds of thousands being killed, around 6.3 million being displaced within the country Air Max Sale , and 5.1 million being forced to flee as refugees outside its borders.

Over the past months, the situation is particularl.
