|BEIJING Tiago Splitter Spurs Jersey , May 28 (Xinhua) -- Many black holes and neutron stars are thought to be hidden in the Milky Way. Since they don't emit visible light, or are covered by dust, only X-ray telescopes can find them.
China will soon launch its first X-ray space telescope, the Hard X-ray Modulation Telescope (HXMT), with the aim of surveying the Milky Way to observe celestial sources of X-rays.
"Our space telescope has unique capabilities to observe high-energy celestial bodies such as black holes and neutron stars. We hope to use it to resolve mysteries such as the evolution of black holes and the strong magnetic fields of neutron stars Sean Elliott Spurs Jersey ," says Zhang Shuangnan, lead scientist of HXMT and director of the Key Laboratory of Particle Astrophysics at the Chinese Academy of Sciences (CAS).
"We are looking forward to discovering new activities of black holes and studying the state of neutron stars under extreme gravity and density conditions, and the physical laws under extreme magnetic fields. These studies are expected to bring new breakthroughs in physics," says Zhang.
Compared with X-ray astronomical satellites of other countries, HXMT has larger detection area Pau Gasol Spurs Jersey , broader energy range and wider field of view. These give it advantages in observing black holes and neutron stars emitting bright X-rays, and it can more efficiently scan the galaxy, Zhang says.
The telescope will work on wide energy range from 1 to 250 keV, enabling it to complete many observation tasks previously requiring several satellites, according to Zhang.
Other satellites have already conducted sky surveys Patty Mills Spurs Jersey , and found many celestial sources of X-rays. However, the sources are often variable, and occasional intense flares can be missed in just one or two surveys, Zhang says.
New surveys can discover either new X-ray sources or new activities in known sources. So HXMT will repeatedly scan the Milky Way for active and variable celestial bodies emitting X-rays.
Zhang says other countries have launched about 10 X-ray satellites, but they have different advantages and therefore different observation focuses.
"There are so many black holes and neutron stars in the universe Nikola Milutinov Spurs Jersey , but we don't have a thorough understanding of any of them. So we need new satellites to observe more," Zhang says.
The study of black holes and neutron stars is often conducted through observing X-ray binary systems. The X-ray emissions of these binary systems are the result of the compact object (such as black hole or neutron star) accreting matter from a companion regular star.
By analyzing binary system X-ray radiation, astronomers can study compact objects such as black holes or neutrons stars.
How do the black holes or neutron stars accrete matter from companion stars? What causes X-ray flares? These are questions scientists want to answer, and China's new space telescope might help.
Lu Fangjun, chief designer of the payload of HXMT Matt Bonner Spurs Jersey , says the space telescope will focus on the Galactic plane. If it finds any celestial body in a state of explosion, it will conduct high-precision pointed observation and joint multiband observation with other telescopes either in space or on the ground.

A lot of the origami airplanes flying you do will be inside home, at home. Inside Home flying has some major advantages - no airflow to carry off the plane or send it crashing to the Earth. No rain to turn it into a soggy wreck. No sun receiving in your eyes. No dead wood or bushes to gobble up the aircraft in their leaved. And Indoors game is great for origami airplane contests because it means everyone flies from below the same considerations. (For more on paper airplane contests, see my web page origami-kids) But indoor flying also has a few problems, namely walls and ceilings Marco Belinelli Spurs Jersey , not to mention furniture, to crash into. The thing to do is to turn these drawbacks into benefits. Here are some games you can play that take advantage of the fact that you`re inside
Paper Plane Golf
This game is a lot like the real game of golf, but you play it indoors using your arm and a paper airplane rather than outside using gold clubs and a ball, and it doesn`t take nearly as long. You can play the game alone or with friends. We recommend using the Count, Slice Manu Ginobili Spurs Jersey , or Butterfly. Choose between three and nine landing spots (these will be your `holes`), such as chairs, tables, and small rugs. They don`t all have to be within one throw of each other; in fact they don`t even have to be I the same room. In golf it`s normal to have to hit a few shots between holes, and in this game you can set it up so that some holes require at least three to five throws. If you want LaMarcus Aldridge Spurs Jersey , number the `holes` with pieces of paper so you remember the order you`re supposed to go in. the object of the game is to land on all the spots using the fewest number of throws. If you set up a challenging and fun course, write down where all the holes are so you can play the course again and improve your `golf` game. This is an excellent game to play if you`re sick and have to stay in bed. It`s also fun if you`re sick and have to stay in bet. It`s also fun if you`re feeling lazy or watching TV. All you need is a paper airplane (almost any kind will do), about 15 feet of string or strong thread, and some tape. Tape the string to the pane near where you`d hold it to throw it. Then tie the other end of the string to your wrist. Choose or set up a target about 10 feet away from where you are and see how.
