This is an artist's concept of the silhouette of the extrasolar planet HAT-P-11b as it passes its parent star. The planet was observed as it crossed in front of its star in order to learn more about its atmosphere.

Newly identified galactic supercluster is home to the Milky Way

A slice of the Laniakea Supercluster in the supergalactic equatorial plane -- an imaginary plane containing many of the most massive clusters in this structure. The colors represent density within this slice, with red for high densities and blue for voids -- areas with relatively little matter. Individual galaxies are shown as white dots. Velocity flow streams within the region gravitationally dominated by Laniakea are shown in white, while dark blue flow lines are away from the Laniakea local basin of attraction. The orange contour encloses the outer limits of these streams, a diameter of about 160 Mpc. This region contains the mass of about 100 million billion suns.Astronomers using the National Science Foundation's Green Bank Telescope (GBT) -- among other telescopes -- have determined that our own Milky Way galaxy is part of a newly identified ginormous...

Study shows how chimpanzees share skills

This is individual KB of the Sonso chimpanzee community of the Budongo Forest in Uganda, using a moss-sponge in November 2011, a behavior she learned by observing her mother.Evidence of new behaviour being adopted and transmitted socially from one individual to another within a wild chimpanzee community is publishing on September 30 in the open access journal PLOS...

2014 Arctic sea ice minimum sixth lowest on record

Arctic sea ice hit its annual minimum on Sept. 17, 2014. The red line in this image shows the 1981-2010 average minimum extent. Data provided by the Japan Aerospace Exploration Agency GCOM-W1 satellite.Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on Sept. 17, according to the NASA-supported National Snow and Ice Data...

Smallest known galaxy with a supermassive black hole

This Hubble Space telescope image shows the gargantuan galaxy M60 in the center, and the ultracompact dwarf galaxy M60-UCD1 below it and to the right, and also enlarged as an inset. A new international study led by University of Utah astronomer Anil Seth and published in the journal Nature found that M60-UCD1 is the smallest known galaxy with a supermassive black hole at its center, suggesting the dwarf galaxy originally was much larger but was stripped of its outer layers by gravity from galaxy M60 over billions of years. M60's gravity also is pulling galaxy NGC4647, upper right, and the two eventually will collide. (NOTE: for a version of this photo with the galaxy names labeled, email <a href="mailto:lee.siegel@utah.edu">lee.siegel@utah.edu</a>.)A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole -- the smallest galaxy known to contain such a massive light-sucking...

Earth's water is older than the sun

This is an illustration of water in our Solar System through time from before the Sun's birth through the creation of the planets.Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth's water...

Climate detectives reveal handprint of human caused climate change in Australia

The impacts of man-made climate change were felt in Australia during its hottest year on record in 2013.Australia's hottest year on record in 2013 along with the accompanying droughts, heat waves and record-breaking seasons of that year was virtually impossible without the influence of human-caused global warming.

Researchers find Asian camel crickets now common in US homes

Greenhouse camel crickets (<i>Diestrammena asynamora</i>), like the one seen here, are native to Asia but are now more common than domestic camel cricket species in homes in the eastern United States.With their long, spiky legs and their propensity for eating anything, including each other, camel crickets are the stuff of nightmares. And now research from North Carolina State University finds...

Giant garbage patches help redefine ocean boundaries

This map shows how researchers from UNSW divided the entire ocean into seven regions whose waters mix very little.
