Q. Pandora's Box: My parents are in their late 80s. When I say they are wonderful people, I mean that sincerely. They have been fair, generous, and loving to me and my siblings and their grandchildren. They are both in declining health--my father probably only has months left to live. I have taken over more of their personal accounts and business--no problem, until I opened my mother's email account for the first time recently to find a receipt.
At the same time, the open cluster Messier 44 (M44), which sits 610 light-years away, will be to the upper left of the moon, forming a neat triangle with M67. Known as the Beehive, M44 is close enough and bright enough to be just visible to the naked eye as a fuzzy spot in the dark sky. Binoculars and small telescopes will reveal about six dozen member stars stretching across 11 light-years of space.
During the World War II Nazi occupation of the Netherlands, it was hidden along with other valuable artworks in a cave in the southern city of Maastricht.

Night vision technology is essential on the modern battlefield but is not without its shortcomings. Conventional night vision goggles (NVGs) have been compared to looking "through toilet paper tubes" on account of their drastically diminished peripheral view. Even the top-of-the-line L-3 Ground Panoramic NGVs -- the ones used by US special forces during the Osama bin Laden raid -- are heavy, cumbersome and require an external power source. However, a breakthrough discovery out of the Australian National University could give us NGVs that are no thicker than a pair of normal sunglasses. Conventional NGVs rely on a process called cascaded secondary emission.
