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...

Study finds marine protected areas inadequate for protecting fish and ocean ecology

Reducing water scarcity possible by 2050

This map shows regional feasibility of strategies to reduce water stress. In most basins under stress, at least five of the six strategies could be applied.Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials...

Stone-tipped spears lethal, may indicate early cognitive and social skills

Spears were carefully constructed to measure the same for the controlled experiments.Attaching a stone tip on to a wooden spear shaft was a significant innovation for early modern humans living around 500,000 years ago. However, it was also a costly behavior...

Orion rocks! Pebble-size particles may jump-start planet formation

Radio/optical composite of the Orion Molecular Cloud Complex showing the OMC-2/3 star-forming filament. GBT data is shown in orange. Uncommonly large dust grains there may kick-start planet formation.Rocky planets like Earth start out as microscopic bits of dust tinier than a grain of sand, or so theories predict.

Duality principle is 'safe and sound'

Scientist uncovers red planet's climate history in unique meteorite

Was Mars -- now a cold, dry place -- once a warm, wet planet that sustained life? And if so, how long has it been cold and dry?

Study: Earth can sustain more terrestrial plant growth than previously thought

Scientists have historically underestimated the potential productivity of the earth's land plants, researchers report in a new study.A new analysis suggests the planet can produce much more land-plant biomass -- the total material in leaves, stems, roots, fruits, grains and other terrestrial plant parts -- than previously...
