A serious challenge to the discovery of gravity waves by the BICEP2 2014 results has appeared: the researchers had underestimated the amount of interstellar dust that could be contaminating their data. (Credit: MacRobert, Andrei Linde)

Scientists have found definitive traces of water on a relatively small exoplanet. HAT-P-11b is the size of Neptune and four times the size of Earth. The exoplanet has copious amounts of both water vapor and hydrogen in its atmosphere. (Credit: NASA)

Our current model of the early inflationary period predicts that the universe should be flat, and so far that has held up. If the universe actually is curved, then the inflationary period must have been more complex than we have thought. (Credit: Koberlien)

Einstein, like no other physicist before or after him, demonstrated how the power of human thought alone, used skillfully, can allow us to consider experiments that could never be practically performed. This line of thinking, these experiments performed only in our imaginations, showed we little humans often have the power to deduce equations that govern the natural world by logical deduction alone.

Astronomers find the strength of the electromagnetic force hasn’t changed in ten billion years. “We didn’t see any difference between electromagnetism in these three distant galaxies and here on Earth, so we don’t support that previous finding,” says Associate Professor Michael Murphy of Swinburne University.

Lt. Will Curtin, a student in the mechanical engineering program, demonstrates the carbon nano-fiber foam (CFF) following its creation in the NPS Functional Materials Laboratory. For the first time, NPS researchers have developed a CFF that behaves as a viscoelastic solid with stable mechanical properties without the need of a polymeric component. (Credit: Javier Chagoya)

The image at the top of the page shows open star clusters M35 and NGC 2158. M35, on the upper left, is relatively nearby at 2800 light years distant, relatively young at 150 million years old, and relatively diffuse, with about 2500 stars spread out over a volume 30 light years across.

Few scientists doubt that Einstein was right. But the mathematics describing the time-dilation effect are “fundamental to all physical theories”, says Thomas Udem, a physicist at the Max Planck Institute for Quantum Optics in Garching, Germany, who was not involved in the research. “It is of utmost importance to verify it with the best possible accuracy.” (Credit: A.

The illustration shows how oscillating photons create an image of frozen light. At first, photons in the experiment flow easily between two superconducting sites, producing the large waves shown at left. After a time, the scientists cause the light to ‘freeze,’ trapping the photons in place. Fast oscillations on the right of the image are evidence of the new trapped behavior.

The quasicrystals formed 4.5 billion years ago in a violent collision between two rocks, among the asteroids that coalesced into planets. The rock with the quasicrystals landed in Chukotka as a meteorite. “They’re part of the primal stuff that formed our solar system,” Dr. Steinhardt said. The above is A penteract (5-cube) pattern using 5D orthographic projection to 2D using Petrie polygon basis vectors overlaid on the diffractogram from an Icosahedral Ho-Mg-Zn quasicrystal.

When space probes, such as Rosetta and Cassini, fly over certain planets and moons, in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A researcher has now analyzed whether or not a hypothetical gravitomagnetic field could have an influence. However, other factors such as solar radiation, tides, or even relativistic effects or dark matter could be behind this mystery. An artist’s rendition of Rosetta probe during a flyby.
