Optical Tunnelling of Electron from an Atom Could Occur Instantaneously

The combination of ab-initio numerical experiments and theory shows that optical tunnelling of an electron from an atom can occur instantaneously.

Optical Nanofiber Inserted into Cold Atomic Cloud for Measuring Temperature

Experimental quantum physics often resides in the coldest regimes found in the universe, where the lack of large thermal disturbances allows quantum effects to flourish. A key ingredient to these experiments is being able to measure just how cold the system of interest is.

Researchers Plan to Flush out Dark Energy Hiding in the Form of 'Chameleons'

If dark energy is hiding in our midst in the form of hypothetical particles called "chameleons," Holger Müller and his team at the University of California, Berkeley, plan to flush them out.

Saturn’s F Ring and Shepherd Satellites Could Be Natural Outcome of Formation of Saturn’s Satellite System

HYODO Ryuki, a second-year student in the Doctoral Program, and Professor OHTSUKI Keiji of the Graduate School of Science at Kobe University have revealed that Saturn’s F ring and its shepherd satellites are natural outcome of the final stage of formation of Saturn’s satellite system. Their finding has been published online in Nature Geoscience on August 17.

Large Hydrocarbon Molecules in Interstellar Space may be the Cause of Diffuse Interstellar Bands

It is one of the most intriguing questions in astrochemistry: the mystery of the diffuse interstellar bands (DIBs), a collection of about 400 absorption bands that show up in spectra of light that reaches the earth after having traversed the interstellar medium. Despite intense research efforts over the last few decades, an assignment of the DIBs has remained elusive, although indications exist that they may arise from the presence of large hydrocarbon molecules in interstellar space. Recent experiments at the Max Born Institute lend novel credibility to this hypothesis.

Supermassive Black Hole Could Have Left Deep Scars on the Heart of the Milky Way

Who left the deep scars on the heart of our Milky Way? In their hunt for elusive clues that might reveal the culprit, an international team of astronomers at the Max Planck Institute for Extraterrestrial Physics has been scouring cosmic images of the X-ray satellite XMM-Newton. The prime suspect is the supermassive black hole lurking at the centre of the Milky Way. But a number of massive stars and supernovae do not appear entirely innocent, either.

Researchers Unravel Mystery of How Jupiter and Saturn Could Have Formed

Researchers at Southwest Research Institute (SwRI) and Queen’s University in Canada have unraveled the mystery of how Jupiter and Saturn likely formed. This discovery, which changes our view of how all planets might have formed, will be published in the Aug. 20 issue of Nature.

Two New Experiments Advance Efforts to Identify Components of Dark Matter and Energy

Two new reports advance efforts to identify components of dark matter and energy, which together comprise about 95% of the universe yet leave much to scientists' imaginations. Both experiments illustrate how basic questions about the universe's development can be addressed by laboratory-scale experiments.

Sensitive XENON100 Detector Helps Know a Lot More About What Dark Matter is Not

Results of the XENON100 experiment are a bright spot in the search for dark matter.

Dark Matter Particles May Annihilate into Dark Radiation When They Collide

Physicists suggest a new way to look for dark matter: They beleive that dark matter particles annihilate into so-called dark radiation when they collide. If true, then we should be able to detect the signals from this radiation.

Low-Density Conditions of Space Reproduced to Measure Interaction of Dark Energy with Normal Matter

Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The latter, which causes galaxies to accelerate away from one another, constitutes the majority of the universe’s energy and mass.

Powerful New Evidence Supports 2013 Observations of Existence of Cosmic Neutrinos

Sorting through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year, researchers using the IceCube Neutrino Observatory have gathered powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos.

Collisions, Accumulation of Pebbles may have led to Formation of Gas Giant Planets

Queen's University researcher Martin Duncan has co-authored a study that solves the mystery of how gas giants such as Jupiter and Saturn formed in the early solar system.

Stars Born Within IC 4651 Cluster Display Wide Variety of Characteristics

Open star clusters like the one seen here are not just perfect subjects for pretty pictures. Most stars form within clusters and these clusters can be used by astronomers as laboratories to study how stars evolve and die.
