NASA's ATLAS thermal testing: You're hot, then you're cold

more »
Once in orbit, the Ice, Cloud and land Elevation Satellite-2 will go from basking in the heat of the sun to freezing in Earth's shadow every 90 minutes. And every second in that orbit, it will need to take thousands of precise measurements of the height of the surface below.

Electrons move like light in three-dimensional solid

A stable bulk material shows the same physics found in graphene, which illuminated the interactions of electron’s orbital motion and its intrinsic magnetic orientation. The new material will be a test ground for theories on how electron interactions in solids shape exotic electron behavior.

Printing silicon on paper, with lasers

more »
In seeking to develop the next generation of micro-electronic transistors, researchers have long sought to find the next best thing to replace silicon. To this end, a wealth of recent research into fully flexible electronic circuitry has focused on various organic and metal-oxide ink materials, which often lack all the favorable electronic properties of silicon but offer superior "printability." Recently, a group of researchers has pioneered a method that allows silicon itself, in the polycrystalline form used in circuitry, to be produced directly on a substrate from liquid silicon ink with a single laser pulse -- potentially ousting its pale usurpers.

Everybody Wants to Rule the Quantum World (Synopsis)

more »

The biggest, most surprising revolution that came along with the development of quantum theory, quantum mechanics and later, quantum field theory, was the overthrowing of the idea of a deterministic Universe, replacing it with a Universe where only a probability distribution of outcomes could be theoretically known, even if you knew all the initial conditions of a system.

But one of the most intriguing concepts to come along with this was borne out through Niels Bohr’s Copenhagen Interpretation, which gives central importance to the observer, a huge change from the classical world, where the observer is merely an onlooker, watching but not influencing the outcome. This, in particular, really resonated with Tears for Fears’ cofounder, Roland Orzabal, with whom physicist Paul Halpern conducted an exclusive interview:

It resonated with me, the suggestion that the person doing the experiment influences the outcome, that the outcome is influenced by what the experiment is indeed trying to prove. It seems to make more sense to me, that our view of the world directly influences and interferes with the world around us, as opposed to the suggestion or feeling that we are mere cogs in an unfeeling machine.

Star Birth in Constellation Cygnus, The Swan Sticker

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


tagged with: envelope sealers, nebulae, gstlnrsr, rcw120, breathtaking astronomy images, star nurseries, ionised gas clouds, star forming regions, european southern observatory, clusters of stars, galaxies, eso, vista

Galaxies, Stars and Nebulae series A gorgeous star forming region in Constellation Cygnus (The Swan). This Hubble image shows a dust-rich, interstellar gas cloud with a new-born star in the centre of the hour-glass shape. The glowing blue of the hydrogen in this nebula is due to the jets being emitted from the forming star as dust falls into into it and this causes the heating and turbulence of the hydrogen. The star, known as S106 IR, is reaching the end of its birth and will soon enter the much quieter period of adulthood known as the main stage.

Carina Nebula - Breathtaking Universe Sticker

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


tagged with: stlrnrsry, star clusters, galaxies, awesome astronomy pictures, constellation puppis, the stern, star nurseries, nebulae, outer space exploration, universe photographs, starfields, european southern observatory, eso, vista

Galaxies, Stars and Nebulae series

A gorgeous set of oval stickers showing the area surrounding the stellar cluster NGC 2467, located in the southern constellation of Puppis ("The Stern"). With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas.

The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region - the lower eye of the Mandrill), as well as vast areas of ionised gas.

The bright star at the centre of the largest pink region on the bottom of the image is HD 64315, a massive young star that is helping shaping the structure of the whole nebular region.

Construction of the LSST telescope begins in Chile

more »
The first stone of the future LSST telescope was laid on 14 April 2015 by the Chilean President Michelle Bachelet, at the Cerro Pachón site in the Chilean Andes. The LSST will be equipped with the most powerful digital camera ever built. The 8.4-meter-diameter telescope will shed light on the nature of dark energy, which accelerates the expansion of the Universe.< The LSST will achieve first light in 2019 and will be fully operational in 2022. The 8.4-meter-diameter telescope will image the sky systematically for ten years, providing a three-dimensional film of the entire visible Universe.
