Just in time for the holidays, a festive Hubble Space Telescope image that resembles a holiday wreath made of sparkling lights! The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our sun and 200 times larger.

RS Puppis rhythmically brightens and dims over a six-week cycle. It is one of the most luminous in the class of so-called Cepheid variable stars. Its average intrinsic brightness is 15,000 times greater than our sun’s luminosity.

The nebula flickers in brightness as pulses of light from the Cepheid propagate outwards. Hubble took a series of photos of light flashes rippling across the nebula in a phenomenon known as a "light echo." Even though light travels through space fast enough to span the gap between Earth and the moon in a little over a second, the nebula is so large that reflected light can actually be photographed traversing the nebula.

One of the best abstract-style animation-music pieces I've come across.

If you're anywhere on the East Coast, Google's Crisis Map may be helpful to you: http://www.theverge.com/2012/10/28/3569660/hurricane-sandy-google-crisis-map

Also, if you are in the NYC area, these maps are a good reference. http://google.org/crisismap/2012-sandy-nyc  & http://project.wnyc.org/news-maps/hurricane-zones/hurricane-zones.html FYI, If you are in Zone A you should have evacuated already.

Stay safe, dry and comfortable out there.

Aurora over White Dome Geyser

Sometimes both heaven and Earth erupt. Colorful aurorae erupted unexpectedly earlier October 2012, with green aurora appearing near the horizon and brilliant bands of red aurora blooming high overhead. A bright +Moon lit the foreground of this picturesque scene, while familiar stars could be seen far in the distance. With planning, the careful astrophotographer shot this image mosaic in the field of White Dome Geyser in Yellowstone National Park in the western USA. Sure enough, just after midnight, White Dome erupted -- spraying a stream of water and vapor many meters into the air. Geyser water is heated to steam by scalding magma several kilometers below, and rises through rock cracks to the surface. About half of all known geysers occur in Yellowstone National Park. Although the geomagnetic storm that created these aurorae has since subsided, eruptions of White Dome Geyser continue about every 30 minutes.

Check out the results of a study on contemporary tablet usage by fellow Googlers +Jenny Gove, +Hendrik Mueller, and +John S. Webb

http://research.google.com/pubs/pub38135.html

See +TechCrunch for coverage:

http://techcrunch.com/2012/10/22/google-research-shows-tablets-are-for-games-and-email-mostly-used-on-couch-in-bed/

Abstract: Tablet ownership has grown rapidly over the last year. While market research surveys have helped us understand the demographics of tablet ownership and provided early insights into usage, there is little comprehensive research available. This paper describes a multi-method research effort that employed written and video diaries, in-home interviews, and contextual inquiry observations to learn about tablet use across three locations in the US. Our research provides an in-depth picture of frequent tablet activities (e.g., checking emails, playing games, social networking), locations of use (e.g., couch, bed, table), and contextual factors (e.g., watching TV, eating, cooking). It also contributes an understanding of why and how people choose to use tablets. Popular activities for tablet use, such as media consumption, shopping, cooking, and productivity are also explored. The findings from our research provide design implications and opportunities for enriching the tablet experience, and agendas for future research.

This is great. The advancement of human-computer interfaces is starting to get very exciting. It will be neat to see how this evolves and what all can be done with it.

Of course, we'll have all new things to worry about, such as whether there are long term side-effects to using a device like this over extended periods of time.

For now though, we can be optimistic about the new possibilities that are being opened up.

See your mind at work, and control devices with your thoughts: http://tmpc.be/RTv8Ls
