An interstellar cloud of gas will remain in hydrostatic equilibrium as long as the kinetic energy of the gas pressure is in balance with the potential energy of the internal gravitational force. Mathematically this is expressed using the virial theorem, which states that, to maintain equilibrium, the gravitational potential energy must equal twice the internal thermal energy.[13] If a cloud is massive enough that the gas pressure is insufficient to support it, the cloud will undergo gravitational collapse. The mass above which a cloud will undergo such collapse is called the Jeans mass. The Jeans mass depends on the temperature and density of the cloud, but is typically thousands to tens of thousands of solar masses.[2] This coincides with the typical mass of an open cluster of stars, which is the end product of a collapsing cloud.

Astronomers explain why disk galaxies eventually look alike

more »

(Phys.org) —It happens to all kinds of flat, disk galaxies – whether they're big, little, isolated or crowded in a cluster. They all grow out of their irregular, clumped appearance and their older stars take on the same smooth look, predictably fading from a bright center to a dim edge.

Detecting biomarkers on faraway planets

more »

(Phys.org) —On Earth, life leaves telltale signals in the atmosphere. Photosynthesis is ultimately responsible for the high oxygen levels and the thick ozone layer. Microbes emit methane and nitrous oxide into the atmosphere, and seaweeds emit chloromethane gas. These chemicals, when present in sufficient quantities, are indicators of life and are known as atmospheric biomarkers. Detecting them in the atmosphere of an exoplanet should, in theory, be a means of discovering whether life exists on any alien worlds.

Building bridges between nanowires

more »

Place a layer of gold only a few atoms high on a surface bed of germanium, apply heat to it, and wires will form of themselves. Gold-induced wires is what Mocking prefers to call them. Not 'gold wires', as the wires are not made solely out of gold atoms but also contain germanium. They are no more than a few atoms in height and are separated by no more than 1.6 nanometres (a nanometre is one millionth of a millimetre). Nanotechnologists bridge this small 'gap' with a copper-phthalocyanine molecule. A perfect fit. This molecule was found to be able to rotate if the electrons coursing towards it possess sufficient energy, allowing it to function as a switch. What's more: the copper atom of this molecule floats in the vacuum above the gap - fully detached. This might allow researchers to identify new properties the nanowires may possess.

Nanocrystal catalyst transforms impure hydrogen into electricity

more »

(Phys.org) —The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts—nanoscale machines that enhance chemical reactions. Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis. In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas. This impure fuel—40 percent less expensive than the pure hydrogen produced from water—remains largely untapped.

On the road to fault-tolerant quantum computing: High temperature superconductivity in a toplogical insulator

more »

Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today's most powerful supercomputers. Other types of problems that quantum computing could tackle would not even be feasible with today's fastest machines. The key word is "reliable." If the enormous potential of quantum computing is to be fully realized, scientists must learn to create "fault-tolerant" quantum computers. A small but important step toward this goal has been achieved by an international collaboration of researchers from China's Tsinghua University and the DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) working at the Advanced Light Source (ALS).

Galaxies, Stars and Nebulae series An awesome photograph from deep space featuring a super bubble in the Large Magellanic Cloud, which is a small satellite of our Milky Way galaxy around 160000 light years from us.
The massive stars of this nebula produce intense radiation, expelling matter at high speeds, and race through their main stage finally to explode as supernovas. The stellar winds of charged hydrogen and other particles and the supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. Blue shows hot regions created by these winds and shocks, while red shows where the dust and cooler gas are found. Yellow regions show where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

Quantum steps towards the Big Bang

more »

(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only an all-encompassing theory of quantum gravity which unifies these two fundamental pillars of physics could provide an insight into how the universe began. Scientists from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Golm/Potsdam and the Perimeter Institute in Canada have made an important discovery along this route. According to their theory, space consists of tiny "building blocks". Taking this as their starting point, the scientists arrive at one of the most fundamental equations of cosmology, the Friedmann equation, which describes the universe. This shows that quantum mechanics and the theory of relativity really can be unified.
