2. Explosion of Monster Star Requires New Supernova Mechanism
NASA's InSight Prepares to Take Mars' Temperature
In this computer graphic, NASA's Voyager 1 probe, moving toward upper left, nears the edge of the sun's influence, flying through a region of space dominated by a "magnetic highway" that helps mediate the flow of particles into and out of the solar system. The region includes particles from the sun's southern hemisphere that have been forced northward by the pressure of the interstellar wind. Voyager 1 is expected to cross the boundary into interstellar space sometime within the next few years if not sooner. (Credit: NASA)

5. The Night Sky Sky & Telescope Friday, August 16
• As August proceeds and nights begin to turn chilly, the Great Square of Pegasus lifts up in the east, balancing on one corner. Its stars are only 2nd and 3rd magnitude, and your fist at arm's length fits inside it. Late this evening the waning gibbous Moon rises below it.
From the Square's left corner extends the main line of the constellation Andromeda: three stars (including the corner) about as bright as those forming the Square.
This whole giant pattern was named "the Andromegasus Dipper" by the late Sky & Telescope columnist George Lovi. It's shaped sort of like a giant Little Dipper with an extra-big bowl, and it's currently raising its contents upward.
Saturday, August 17
• The actual Little Dipper, meanwhile, is tipping far over leftward in the north. It's less than half as long as the Andromegasus Dipper, and most of it is much fainter. As always, you'll find that it's oriented more than 90° counterclockwise compared to Andromegasus.
Sunday, August 18
• As summer progresses and Arcturus moves down the western sky, the kite figure of Bootes that sprouts from Arcturus tilts to the right (depending on your latitude). The kite is narrow, slightly bent with its top
leaning right, and 23° long: about two fists at arm's length. Arcturus is its bottom point where the stubby tail is tied on.
The Big Dipper now slants at about the same height in the northwest, to the Kite's right.
Monday, August 19
• Whenever bright Vega crosses nearest your zenith, as it does right after dark now, you know that the Sagittarius Teapot must be at its highest due south, even if it's hidden by buildings or trees.
Two hours later when Deneb crosses closest to the zenith, it's the turn of little Delphinus and boat-shaped Capricornus down below it to stand at their highest due south.
