Finding clouds of water floating in the atmosphere of an alien world is a significant find. Now, astronomers have reported preliminary findings that water clouds have been detected in the atmosphere of a brown dwarf, a mere 7.3 light-years from Earth. (Credit: NASA, JPL-Caltech, O’neil)

NASA mechanical engineer, Brian Trease, worked with Brigham Young University doctoral student Shannon Zirbel, and collaborated with origami expert Robert Lang, who has long been active in promoting it in science, and BYU professor Larry Howel, to combine different traditional folds for an 82-foot solar array that whirls down to 8.9 feet.

“If we find a noise we can’t get rid of, we might be detecting something fundamental about nature – a noise that is intrinsic to space-time,” said Physicist Aaron Choi, the holometer project’s lead scientist. (Credit: NASA, ESA)

In this picture, which combines views from Hubble and the Keck-II telescope on Hawaii (using adaptive optics), you can see a foreground galaxy that is acting as the gravitational lens. The galaxy resembles how our home galaxy, the Milky Way, would appear if seen edge-on. But around this galaxy there is an almost complete ring — the smeared out image of a star-forming galaxy merger far beyond. (Credit: NASA, ESA)

With a circumference of 52km, the “Higgs Factory” would be almost twice the size of Europe’s equivalent, and significantly more powerful. The Chinese said it is due to be completed by 2028. Image above is the Large Hadron Collider. (Credit: Getty)

“It’s the most distant object for which the spin has been directly measured. The universe is about 13.7 billion years old, so this is going significantly back towards when the epoch of furious galaxy formation was happening,” says, Astrophysicist, Mark Reynolds.

Dark matter and dark energy continue to be cosmological conundrum for physicists worldwide. Nobel prize winner Brian Schmidt offers his perspective in an interview. The image shown here is of the ALMA antennas and the constellations of Carina (The Keel) and Vela (The Sails). The dark, wispy dust clouds of the Milky Way streak from middle top left to middle bottom right. (Credit: ESO, B. Tafreshi)

. A novel class of electronic materials – the so-called transition-metal oxides – hold promise for exciting, new applications. Where layers of this novel class of electronic materials touch, often a unique, and unprecedented phenomenon occurs: for instance, the interface between two insulators can become superconducting, or a strong magnetic order can build up between two non-magnetic layers.

What’s that dot on the Sun? If you look closely, it is almost perfectly round. The dot is the result of an unusual type of solar eclipse that occurred in 2006. Usually it is the Earth’s Moon that eclipses the Sun. This time, the planet Mercury took a turn. (Credit: D. Cortner, NASA, K. Schmidt)
“Maybe we will see how galaxies are magnetically connected to intergalactic space. This is a key experiment in preparation for the planned Square Kilometre Array (SKA) that should tell us how cosmic magnetic fields are generated,” says Rainer Beck, lead astronomer with the Max Planck Institute.

Although they are gigantic, ranging from one to a few hundred lightyears in size, the physical process that causes these nebulae to emit their own light (rather than merely reflect light from nearby stars) occurs at the atomic level. It is the same process that makes familiar florescent lights shine here on Earth. (Credit: NASA, Prozesky)

A patterned 3-D grid of tiny whirlpools, called quantum vortices, populate a nanoscale droplet of superfluid helium. Researchers found that in a micron-sized droplet, the density of vortices was 100,000 times greater than in any previous experiment on superfluids. An artistic rendering of a wheel-shaped droplet can be seen in the distance. (Credit: SLAC National Accelerator Laboratory)
