Observatory: Earthlike Planets May Be Merely an Illusion

more »

Researchers have found that Gliese 581g and its presumed neighbor, Gliese 581d, don’t exist. They were simply illusions created by the star they supposedly orbited.

Technology using microwave heating may impact electronics manufacture

original post »

Engineers at Oregon State University have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating – essentially the same forces that heat up leftover food with such efficiency. This graphic outlines the basic functions of a “continuous flow ” reactor that could be used to produce a variety of high quality nanoparticles, using microwave heating. Instead of warming up yesterday’s pizza, however, this concept may provide a technological revolution. It could change everything from the production of cell phones and televisions to counterfeit-proof money, improved solar energy systems or quick identification of troops in combat. The findings, recently published in Materials Letters, are essentially a “proof of concept” that a new type of nanoparticle production system should actually work at a commercial level. “This might be the big step that takes continuous flow reactors to large-scale manufacturing,” said Greg Herman, an associate professor and chemical engineer in the OSU College of Engineering. “We’re all pretty excited about the opportunities that this new technology will enable.” Nanoparticles are extraordinarily small particles at the forefront of advances in many biomedical, optical and electronic fields, but precise control of their formation is needed and “hot injection” or other

Saturn Solar Eclipse Posters

Here's a great poster featuring a beautiful image from deep space


tagged with: space, astronomy, saturn, stars, planets, earth, cassini, sun, exploration, rings, moons

You may think that this is a fake image, but it is actually a real photo taken from the Cassini space craft of Saturn eclipsing the Sun. The rings glow brightly as the light filters through them and the reflect that light all the way around to the back of the planet creating a surreal effect. A special surprise in the photo is that, just to the left of the rings, that bright blue dot is Earth, where you're sitting right now. This is truly a fascinating and beautiful image.

Carina Nebula in Argo Navis constellation Square Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: stars, galaxies, astronomy, envelope sealers, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, ngc 3372

Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

Comet Pan-STARRS marches across the sky

more »

NASA's NEOWISE mission captured a series of pictures of comet C/2012 K1 -- also known as comet Pan-STARRS -- as it swept across our skies in May 2014. The comet is named after the astronomical survey project called the Panoramic Survey Telescope and Rapid Response System in Hawaii, which discovered the icy visitor in May 2012.
