nousek造句

• Dr . John Nousek, a professor of astrophysics at Pennsylvania State University who is the mission director, pointed out that the name Swift was not an acronym but a design philosophy.
• Swift may be ready to observe its first flash of gamma radiation about three weeks into the flight, Nousek said, with full capability expected in 45 days and a life span of at least two years.
• A few longer-lasting gamma ray bursts, the more common type, have been observed in some detail by previous spacecraft . The afterglows, Nousek said, appear to support the hypothesis of immense stellar explosions, or hypernovas, as the most likely cause.
• "If you don't move fast enough, you miss seeing the environment closest to where the explosion occurred, " Nousek said . " That material probably gives you the best information about what caused the explosion and what the conditions are like in the afterglow ."
