9 November is reserved to Hedy Lamarr
She is remembered for her beauty on the silver screen, but the Hollywood actor spent her nights inventing a weapons communication system that was a precursor to wireless technologies including Bluetooth and Wi-Fi.

Lamarr also, captured international attention as the first female actor to simulate an orgasm in a non-pornographic film. 
Lamarr quickly got bored of Hollywood, though, and decided to try her hand at helping the Allied war effort instead. She had learned about military technology from her first husband, arms manufacturer Friedrich Mandle, and decided to use that knowledge for the greater good
.
She teamed up with her friend George Antheil, a composer, to figure out how to help stop German submarines from jamming Allied radio signals using the same mechanisms found in pianos. In 1942, she developed the “secret communication system,” a frequency-hopping mechanism that laid the foundation for the development of Bluetooth and wi-fi technology. She died at the age of 85 in 2000.

"Her idea of a good evening was a quiet dinner party with some intelligent friends where they could discuss ideas."
Indeed she falls in the category "Brains before beauty". ;)

The Incredible Variety of Extraterrestrial Worlds
Exoplanets (or extrasolar planets) are planets beyond our own solar system: they orbit a star other than the Sun. Nearly 2000 exoplanets have been discovered since 1988, mostly with NASA’s Kepler space telescope. It has intensified interest in the search for extraterrestrial life.

This new poster shows over 500 extrasolar planets and demonstrates how much they vary. The visualization, created by graphic artist and writer Martin Vargic from Slovakia, is based on the estimated radius and temperature of the planets, however other factors, such as density, age or stellar metallicity were also taken into consideration.

All the various known classes of exoplanets are shown on the graphic, such as super-Earths, hot Jupiters, hot Neptunes, water worlds, gas dwarfs or superdense diamond planets. 
 Zoom in and explore!

Heads Up!! Last time to see a Super Blood Moon eclipse until 2033!
There is a total eclipse of the moon on the night of September 27-28, 2015. It happens to be the closest supermoon of 2015. It’s the Northern Hemisphere’s Harvest Moon, or full moon nearest the September equinox. This September full moon is also called a Blood Moon, because it presents the fourth and final eclipse of a lunar tetrad: four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. 

The total lunar eclipse is visible from the most of North America and all of South America after sunset September 27. From eastern South America and Greenland, the greatest eclipse happens around midnight September 27-28. In Europe, Africa and the Middle East, the total eclipse takes place in the wee hours of the morning, after midnight and before sunrise September 28.

H/t Earthsky; thanks for the nice reading!

Tardigrades: Practically Invisible, Indestructible ‘Water Bears’

Tardigrades are tiny creatures that survive under conditions few others can tolerate. The biggest adults may reach a body length of 1.5 mm (0.059 in), the smallest below 0.1 mm. Newly hatched tardigrades may be smaller than 0.05 mm.

Most tardigrades are phytophagous (plant eaters) or bacteriophagous (bacteria eaters), but some are predatory.

They live just about everywhere: in moss and lichens, but also in bubbling hot springs, Antarctic ice, deep-sea trenches and Himalayan mountaintops. They can survive for years as a dried-out ball, with no water, and have even survived the extreme cold and radiation of outer space.

Typically taupe-ish and somewhat translucent, they are variously described as resembling minuscule hippopotamuses (if hippos had giant snouts and eight legs, each with several claws), mites or, most commonly, bears.
Tardigrades (also known as water bears or moss piglets) are water-dwelling, segmented micro-animals, with eight legs.

The German pastor Johann August Ephraim Goeze, who first discovered them in 1773, originally named the tardigrade kleiner Wasserbär (Bärtierchen today), meaning 'little water bear' in German.
The name Tardigrada means "slow walker" and was given by Lazzaro Spallanzani in 1776. The name water bear comes from the way they walk, reminiscent of a bear's gait. 

Since 1778, over 1,150 tardigrade species have been identified.
