“This is a long-standing, really neat experimental idea,” says Paul Lett, of the National Institute of Standards and Technology in GaithersburgLett, “Now we have to see whether or not it will lead to something practical, or will remain just a clever demonstration of quantum mechanics.”(CreditBarreto-Lemos, Vergano)

The Borexino neutrino detector uses a sphere filled with liquid scintillator that emits light when excited. This inner vessel is surrounded by layers of shielding and by about 2,000 photomultiplier tubes to detect the light flashes.(Credit: Borexino Collaboration)

MOLECULAR MODEL In the molecular model, quark-antiquark pairs form two color-neutral mesons that become weakly linked as a molecule.DIQUARK MODEL The particles form quark-quark and antiquark-antiquark pairs, which are forced to combine to balance their color charges.

A computer model shows one scenario for how light is spread through the early universe on vast scales (more than 50 million light years across). Astronomers will soon know whether or not these kinds of computer models give an accurate portrayal of light in the real cosmos. (Credit: Andrew Pontzen/Fabio Governato)

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.

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.

To celebrate the NASA-ESA Hubble Space Telescopes 16 years of success, NASA and the European Space Agency are releasing this mosaic image of the starburst galaxy, Messier 82 (M82), made in March 2006. It is the sharpest wide-angle view ever obtained of M82, a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions. Located 12 million light-years away, it is also called the “Cigar Galaxy” because of the elongated elliptical shape produced by the tilt of its starry disk relative to our line of sight. (AP Photo/NASA-ESA)
This image of the galaxy Messier 82 is a composite of data from the Chandra X-Ray Observatory, the Hubble Space Telescope and the Spitzer Space Telescope. The intermediate-mass black hole M82 X-1 is the brightest object in the inset, at approximately 2 o’clock near the galaxy’s center. (Credit: NASA/H. Feng et al.)
