Astrophoto of M31, the Andromeda Galaxy, taken with an 85mm (3.35 in) diameter Takahashi a...

While nearly everyone enjoys a good astrophoto, the precision with which the astrograph (the telescope taking the photograph) must follow the stars is not widely appreciated. To take a good astrophoto of any but the brightest objects requires following their motion through the sky accurately. There are a number of approaches toward addressing this problem in the digital era. Perhaps the best option has now been enabled by Innovations Foresight's new ON-Axis Guider (ONAG).  Read More

CyFy WristView lets you check your blind spot

Despite some recent design improvements in field, it's still pretty hard to pedal around with a helmet-mounted rear-view mirror and look stylish. There are, however, alternatives for the fashion conscious cyclist. The CyFy WristView integrates a rear-view mirror into a bracelet, giving you a low profile, adjustable means of checking for traffic behind you.  Read More

The Isoteko bicycle helmet mirror is designed to be unobtrusive and good-looking

According to the U.S. Department of Transportation, collisions between bicycles and motor vehicles resulted in the deaths of 618 cyclists in 2010 ... and that’s just in the United States. Regardless of who was at fault in those accidents, one thing is certain – urban cyclists are safer when they’re better able to keep tabs on the vehicles around them. While helmet-mounted mirrors are a great help in that regard, many cyclists don’t use them. That’s why Canadian entrepreneurs Greg Maxwell and Richard Seck invented the Isoteko mirror.  Read More

Audi's digital rear-view mirror that will make its production debut in the R8 e-tron

Audi’s digital rear-view mirror, which made its debut in the R18 e-tron Quattro and R18 ultra race cars at this year’s Le Mans 24 Hours, is set to enter small scale production at the end of this year in the Audi R8 e-tron. Unlike previous rear-view mirrors from the likes of Ford, Toyota and Mazda, which dedicate only a percentage of the mirror’s surface area to displaying vision from a rear-view camera, Audi’s digital rear-view mirror does away with the conventional mirror altogether.  Read More

NASA researchers are trying a 'scotch tape' design to build larger, more affordable X-ray ...

A team led by NASA's Maxim Markevitch is investigating the possibility of building bigger X-ray telescope mirrors – up to thirty times as large as today's – using a plastic tape coated with a reflective material and then, just like a roll of Scotch tape, tightly rolled on itself. By studying cosmic rays and distant galaxy clusters, such large and significantly cheaper mirrors would allow us to learn more about the birth and evolution of the universe.  Read More

A dish-shaped mirror focuses sunlight onto a glass ball, which distributes it evenly onto ...

Borrowing technology from sophisticated telescope mirrors as well as high-efficiency solar cells used for space exploration, a group of students and researchers at the University of Arizona are putting the final touches on a novel power plant that promises to generate renewable energy twice as efficiently as standard solar panel technology with highly competitive costs and a very small environmental impact.  Read More

Dr. Hicks' mirror (top) as compared to a regular flat driver's side mirror

While there are already various anti-blind-spot automobile mirrors on the market, these all tend to incorporate a very curved surface that drastically distorts the appearance of objects seen in them – given that drivers use their mirrors to avoid getting in accidents, it’s kind of important that those mirrors show the surrounding traffic as it really is. That’s why Dr. Andrew Hicks, a mathematics professor at Philadelphia’s Drexel University, has created a side mirror that eliminates the blind spot, while causing almost no distortion.  Read More

From Earth's perspective, on June 5 and 6, Venus will pass across the face of the Sun. By observing the tiny fraction of sunlight that passes through Venus's atmosphere using the Hubble Space Telescope, it is hoped that the planet's atmospheric makeup can be determined. Though we already know the nature of Venus's atmosphere, it is hoped the event will help astronomers hone techniques, already in use, that may one day help to identify Earth-like planets in far-away solar systems. The catch? Hubble cannot observe the Sun directly. Instead it will look at the Moon to observe reflected light.  Read More

Located just outside the center of Berlin in Germany, Propeller Island City Lodge is an unusual hotel with "artistic" rooms that include flying beds and upside down fittings. The rooms and interior objects have all been created by the German artist Lars Stroschen, in an attempt to create a hotel that is a "living work of art". While sleeping in a coffin or a recreated dungeon might not be what you imagined a trip to Berlin to be like, the hotel no doubt leaves an impression and we thought it merited a mention on this Friday the 13th.  Read More

Danish architectural firm MLRP has come up with a novel way to prevent graffiti and vandalism of a local town hall. By turning the outside walls into mirrors, the team successfully transformed a "drab" building into a local attraction that is hopefully resistant to future graffiti attempts.  Read More
