What's in the sky tonight?

-Have you ever wondered what a lunchbox suspended 112,000 feet above Earth's surface would look like? The answer is, this:

-This is actually a Space Weather Buoy--a lunchbox containing a cosmic ray detector, cameras, GPS trackers, a thermometer and other sensors. It flew to the stratosphere on August 22nd tethered to a suborbital helium balloon. In collaboration with Spaceweather.com, the students of Earth to Sky Calculus have been launching these buoys on a regular basis to study the effect of solar activity on Earth's upper atmosphere. Soon, they will release results from a year-long campaign covering altitudes of interest to aviation, space tourism, and ozone research.

The students wish to thank Eden Botanicals for sponsoring the August 22nd flight. (Note their logo on the corner of the payload.) This was the student group's 58th successful launch--almost all paid for by a combination of donations and commercial advertising. If you would like your own logo sent to the stratosphere, visit the spaceweather.com website and contact dr.tony.phillips@earthlink.net .

Why does this galaxy have such a long tail? In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a mere 420 million light-years distant toward the northern constellation Draco. Its eye-catching tail is about 280 thousand light-years long and features massive, bright blue star clusters. One story goes that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole by their gravitational attraction. During the close encounter, tidal forces drew out the spiral galaxy's stars, gas, and dust forming the spectacular tail. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper right. Following its terrestrial namesake, the Tadpole Galaxy will likely lose its tail as it grows older, the tail's star clusters forming smaller satellites of the large spiral galaxy.
