The international University of California, Riverside-led SpARCS collaboration has discovered four of the most distant clusters of galaxies ever found, as they appeared when the universe was only 4 billion years old. Clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars, as well as hot gas and mysterious dark matter. Spectroscopic observations from the ground using the W. M. Keck Observatory in Hawaii and the Very Large Telescope in Chile confirmed the four candidates to be massive clusters. This sample is now providing the best measurement yet of when and how fast galaxy clusters stop forming stars in the early Universe.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) surveyed dozens of young stars -- some Sun-like and others approximately double that size -- and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks. In contrast, the lower-mass, Sun-like stars have debris disks that are virtually gas-free.

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

The center of the Milky Way galaxy is currently a quiet place where a supermassive black hole slumbers, only occasionally slurping small sips of hydrogen gas. But it wasn't always this way. A new study shows that 6 million years ago, when the first human ancestors known as hominins walked the Earth, our galaxy's core blazed forth furiously. The evidence for this active phase came from a search for the galaxy's missing mass.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

Ahuna Mons is a volcano that rises 13,000 feet high and spreads 11 miles wide at its base. This would be impressive for a volcano on Earth. But Ahuna Mons stands on Ceres, a dwarf planet less than 600 miles wide that orbits the Sun between Mars and Jupiter. Even stranger, Ahuna Mons isn't built from lava the way terrestrial volcanoes are -- it's built from ice.

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is gusty and turbulent. But near the sun where it originates, this wind is structured in distinct rays, much like a child's simple drawing of the sun. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.

In order for Hermine or any other tropical depression, to intensify there must be a pathway for heat energy from the ocean surface to enter the atmosphere. For Hermine, the conduit may have been one of the two "hot towers" that the Global Precipitation Measurement mission or GPM core satellite observed on Aug. 31 at 4:09 p.m. EDT (2009 UTC).

Operation IceBridge, NASA's airborne survey of polar ice, is flying in Greenland for the second time this year, to observe the impact of the summer melt season on the ice sheet. The IceBridge flights, which began on August 27 and will continue until September 16, are mostly repeats of lines that the team flew in early May, so that scientists can observe changes in ice elevation between the spring and late summer.

Terzan 5, 19 000 light-years from Earth in the constellation of Sagittarius (the Archer) and in the direction of the galactic centre, has been classified as a globular cluster for the forty-odd years since its detection. Now, an Italian-led team of astronomers have discovered that Terzan 5 is like no other globular cluster known.

Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

The majestic auroras have captivated humans for thousands of years, but their nature -- the fact that the lights are electromagnetic and respond to solar activity -- was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.

An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.

Ecosystems in the Catalan coastal system in Spain are worth €2,573 million per year to local citizens, according to new research. By placing a value on ecosystems the research has provided insight into integrated coastal zone management (ICZM) in the area.

A new study highlights the economic importance of coastal and marine areas and the urgent need to develop concrete methods for assessing their value. Researchers say the need is especially strong now as climate change's impacts could reduce the economic value of coastal and marine environments.

A recent report has assessed the latest research on the adverse affects of noise on health, focusing on approaches to estimating the economic cost of noise. This information could help policy makers tasked with designing cost-effective noise reduction and management policies.

Payments for ecosystem services (PES) are one of a number of policy options available to support the provision of ecosystem services. Based on the characteristics of ecosystem services, a recent study has developed a framework for deciding when payments are a suitable tool for delivering ecosystem services.

Some 'intangible' ecosystem services, such as the aesthetic and cultural value, as well as the recreational use of land, are particularly difficult to price. New research has proposed three explorative methods to value these more intangible services using landscape evaluation, statistics on level of recreational use and the price of real estate in the area.

In theory, payment for environmental services (PES) is a market mechanism but, in practice, it depends on intervention from the state or community. This is the conclusion of a new review of case studies that indicates that PES relies on public bodies and communities to act as intermediaries in the trading of services.

Transaction costs can be incurred during various phases of environmental policy making, from planning through to enforcement. A recent study has examined what influences these costs and concluded that policy selection and evaluation could benefit from a better understanding of the causes of these transaction costs.

Researchers have examined two cases of managed realignment in the UK, whereby coastal areas are deliberately flooded to recreate protective salt marshes. They demonstrated that a sequential decision support system (DSS) can be combined with an ecosystem services approach to provide a robust economic valuation of managed realignment’s benefits. For the case studies analysed, the benefits of managed realignment were found to outweigh costs in the long-term.

When natural disasters, such as earthquakes, storms and hurricanes, are reported in the media, they are often accompanied by an assessment of the cost of the disaster. While such information can be useful to help governments and international organisations target aid and recovery efforts, the details of what is included in the assessment, and the methods used, are often unclear.

Marine litter not only causes environmental damage, but has significant economic costs for industry. A recent study has now estimated that marine litter in the Asia-Pacific region is likely to cost over US$1.26billion per year in damage to marine industries. Policy options for reducing this cost are explored.

A new tool allows European businesses to see how, through informed decision-making, conserving the ecosystems they depend on is not only environmentally responsible, but can also increase profits, reduce risk and boost the value of their product or services.

A new study has proposed a method to place monetary value on green infrastructure at both a project and regional scale, which illustrates the value of investing in green infrastructure to the public and other stakeholders.

The design and implementation of Payments for Ecosystem Services (PES) schemes could benefit from lessons learned from the management of common pool resources (CPR). By examining previous research into CPR, an international team of researchers has demonstrated that six sustainable management characteristics of CPRs also hold lessons for PES practitioners.

Payments for Ecosystem Services (PES) schemes offer direct payments for communities and individuals in exchange for conserving areas of land reserved for conservation for their environmental qualities. The results of an Ecuadorian study highlight key aspects for designing successful PES schemes and demonstrate how investments associated with PES can also benefit poor communities.

Understanding the role of neighbourhood networks in encouraging farmers to participate in Payments for Ecosystem Services (PES) schemes is important as this can help to create local patterns of high and coordinated uptake of PES schemes, and thus an impact on ecosystem protection at a wider, landscape level. This is the outcome of a recent UK study, which found that neighbourhood networks were particularly important for small, remote communities.

According to a recent viewpoint article, future agri-environmental schemes (AES) can more effectively pay for the provision of ecosystem services at a landscape level if they are prepared, designed and implemented in a collaborative and coordinated manner.

Wetland management needs to consider the role wetlands play in supporting livelihoods and wellbeing as well as more traditional conservation goals, according to UK researchers. Such a ‘human-centric’ approach, would link hydrological conservation to societal benefits, including clean water, food production, flood protection and improved human health.

Soils play a vital role in the Earth's life-support system, yet their importance and value to society is not always recognised. A recent study suggests that incorporating soils into a National Capital and Ecosystem Services framework will raise the profile of soils and enable soils to be more easily integrated into policy decisions.

A recent study has assessed the costs and effectiveness of reducing phosphorus pollution for lakes in Scotland, UK, to achieve good ecological status as required by the EU’s Water Framework Directive (WFD). It was found that phosphorus in 72% of the lake area in Scotland could be mitigated at a cost of £5.7 million (€7 million) per year, which is considered a proportionate or reasonable cost given the resulting social benefits.
