Asteroid to graze past Earth this summer...but how close? If you liked 2004 MN4, you're bound to enjoy 2006 BQ6. Very small but real chance it could even hit around the end of July, beginning of August this year. NASA isn't officially tracking it yet, but they are including it in their report of upcoming close approaches, where the minimum possible distance is...zero. The space.com discussion puts everything into perspective, including graphs and charts and such.
Big object sighted... if you liked Sedna and Quaoar, you're bound to love 2003 EL61, which has been found lurking in photographs from a couple of years ago. There appears to be some speculation that this one could be larger than Pluto.
On March 5, 1979, astronomers saw a burst of gamma rays so strong it swamped their detectors. Another rare burst in 1998 helped confirm the existence of magnetars, intensely powerful magnetic stars, unusual enough that there might only be a dozen or so in the galaxy. Another one has just been found --when it let off a burst last December that, for a fraction of a second, was brighter than the full moon.
