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.

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. The map could yield insights into the formation of giant ocean garbage patches, as well as ocean ecology.The Great Pacific Garbage Patch is an area of environmental concern between Hawaii and California where the ocean surface is marred by scattered pieces of plastic, which outweigh plankton in...

Ancient mammal relatives were active at night 100 million years before origin of mammals

The arrow on this gorgonsopian skull indicates where the fossil scleral ring is found.Most living mammals are active at night (or nocturnal), and many other mammal species are active during twilight conditions. It has long been thought that the transition to nocturnality occurred...

Cause of global warming hiatus found deep in the Atlantic Ocean

(Top) Global average surface temperatures, where black dots are yearly averages. Two flat periods (hiatus) are separated by rapid warming from 1976-1999.  (Middle) Observations of heat content, compared to the average, in the north Atlantic Ocean. (Bottom) Salinity of the seawater in the same part of the Atlantic. Higher salinity is seen to coincide with more ocean heat storage.Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at Earth's surface. At first this was a blip,...

Best view yet of merging galaxies in distant universe

ALMA, the VLA, and other telescopes used gravitational lensing to obtain the best view yet of a collision that took place between two galaxies when the Universe was only half its current age. These new studies of the galaxy H-ATLAS J142935.3-002836 have shown that this complex and distant object looks surprisingly like the well-known local galaxy collision, the Antennae Galaxies. The foreground galaxy is doing the lensing and around it is an almost complete ring &#8212; the smeared out image of a star-forming galaxy merger far beyond. This picture combines the views from the Hubble Space Telescope and the Keck-II telescope on Hawaii (using adaptive optics) along with the ALMA images shown in red. The ALMA data also give information about the motions of the material in the distant merging galaxies and were vital in unravelling the complex object.An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) -- among other telescopes -- has obtained the best...
