Galaxies forming stars at extreme rates nine billion years ago were more efficient than average galaxies today, researchers find.

The Global Precipitation Measurement (GPM) mission core satellite analyzed rainfall within Tropical Storm Koppu and identified areas of some intense thunderstorms.
Launching humans to Mars may not require a full tank of gas: A new MIT study suggests that a Martian mission may lighten its launch load considerably by refueling on the moon.
Previous studies have suggested that lunar soil and water ice in certain craters of the moon may be mined and converted to fuel. Assuming that such technologies are established at the time of a mission to Mars, the MIT group has found that taking a detour to the moon to refuel would reduce the mass of a mission upon launch by 68 percent.
Ushering new technologies from the university lab to the marketplace has long been a challenge, with many stalling indefinitely due to a lack of funding. But a model of investing has developed over the past 15 years to help bridge that gap with some stunning successes, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
RIVERSIDE, Calif. -- In recent years the practice of Android rooting, that is the process of allowing an Android phone or tablet to bypass restrictions set by carriers, operating systems or hardware manufacturers, has become increasingly popular.
Scientists using NASA's Hubble Space Telescope have produced new maps of Jupiter -- the first in a series of annual portraits of the solar system's outer planets.
Collecting these yearly images -- essentially the planetary version of annual school picture days for children -- will help current and future scientists see how these giant worlds change over time. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry.
Much like the flapping of a windsock displays the quick changes in wind's speed and direction, called turbulence, comet tails can be used as probes of the solar wind - the constant flowing stream of material that leaves the sun in all directions. According to new studies of a comet tail observed by NASA's Solar and Terrestrial Relations Observatory, or STEREO, the vacuum of interplanetary space is filled with turbulence and swirling vortices similar to gusts of wind on Earth.
A study of spiral galaxies seen edge-on has revealed that halos of cosmic rays and magnetic fields above and below the galaxies' disks are much more common than previously thought. Edge-on galaxies, when seen with the naked eye, look like a line in the sky.An international team of astronomers including lead author and Queen's postdoctoral student Theresa Wiegert and Queen's researcher Judith Irwin (Physics, Engineering Physics and Astronomy) used the Karl G.
Ancient memory devices such as handwriting were based on mechanical energy--but in the modern world they have given way to devices based generally on electrical manipulation.
Today, scientists from the RIKEN Center for Emergent Matter Science may be about to wind back time. In a study published in Nature Communications, they have found a way to manipulate skyrmions--tiny nanometer-sized magnetic vortices found at the surface of magnetic materials--using mechanical energy.
While new evidence suggests that Mars may harbor a tiny amount of liquid water, it exists today as a largely cold and arid planet. Three billion years ago, however, the situation may have been much different.
In 2012 the Mars Curiosity rover beamed images back to Earth containing some of the most concrete evidence that water once flowed in abundance on the planet. Small, remarkably round and smooth pebbles suggested that an ancient riverbed had once carried these rocks and abraded them as they traveled.
A study of spiral galaxies seen edge-on has revealed that "halos" of cosmic rays and magnetic fields above and below the galaxies' disks are much more common than previously thought.
An international team of astronomers used the Karl G. Jansky Very Large Array (VLA) to study 35 edge-on spiral galaxies at distances from 11 million to 137 million light-years from Earth. The study took advantage of the ability of the VLA, following completion of a decade-long upgrade project, to detect radio emission much fainter than previously possible.
New research at the Luxembourg School of Finance suggests that investor belief in higher returns by investing in private equity investment funds may be misplaced, calling into question their rising popularity.
The hope is to develop efficient and environmentally friendly solar energy applications. Solar energy is an inexhaustible resource that we currently only utilise to a very limited extent. Researchers around the world are therefore trying to find new and more efficient ways to use the energy in sunlight.
The technique the researchers in Lund are working on is solar cells consisting of a thin film of nanostructured titanium dioxide and a dye that captures solar energy. Today, the best solar cells of this type use dyes containing ruthenium metal - a very rare and expensive element.
Tropical Cyclone 03A formed in the Arabian Sea, Northern Indian Ocean on October 10 and by October 12 it weakened to a remnant low pressure area. NASA's Terra satellite happened over the storm when it developed and caught a visible image of this short-lived storm.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite passed over Tropical Cyclone 03A as it was forming on Oct. 10, 2015 at 06:30 UTC (2:30 a.m. EDT). The MODIS image showed a concentration of storms around the center of circulation.
An international team of astronomers, including Dr Simon Vaughan from the University of Leicester's Department of Physics and Astronomy, has discovered a previously unknown link between the way young stars grow and the way black holes and other exotic space objects feed from their surroundings.
