31. The intrepid bearers of the celestial sword
    A group of Chinese scientists have something on their mind, and it does not get any darker than this.   This is a search unlike any other: It's going on in the darkness of outer space, and the hunters have no idea where their quarry is or when it will pop up. In fact they do not know what they ar......

37. First study on the X-ray imaging of Kelvin-Helmholtz waves at the magnetopause
    The solar wind charge exchange (SWCX) process occurs when a high charge state solar wind ion (e.g., O7+) encounters a neutral atom or molecule (e.g., H) and picks up an electron in an excited state. The ion then emits a photon when it decays to a lower energy state and thus may lead to the satell......
