Explosive volcanic eruptions that shot jets of hot ash, rock and gas skyward are the likely source of a mysterious Martian rock formation, a new study finds. The new finding could add to scientists' understanding of Mars's interior and its past potential for habitability, according to the study's authors.
The close collaboration between the Met Office and the China Meteorological Administration-National Satellite Meteorological Center helped support China in generating high quality satellite data for weather and climate services.
Scientists from the University of Maryland, the University of Leeds and the University of California, San Diego, have reviewed decades of satellite measurements to reveal how and why Antarctica's glaciers, ice shelves and sea ice are changing. Their report, published in a special Antarctica-focused issue of the journal Nature on June 14, 2018, explains how ice shelf thinning and collapse have triggered an increase in the continent's contribution to sea level rise.
A new analysis of data from NASA's Dawn mission suggests that organic matter may exist in surprisingly high concentrations on the dwarf planet's surface.
Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3.0 mm) coming in the last five years alone. The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), and are published today in Nature. It is the most complete picture of Antarctic ice sheet change to date -- 84 scientists from 44 international organizations combined 24 satellite surveys to produce the assessment.
Monitoring Antarctica from space has revealed how its ice is being lost to the oceans, providing crucial insight into the continent's response to a warming climate.
University of Groningen astronomers have discovered relics of merger events in the Milky Way halo. Five small groups of stars appear to represent mergers with smaller galaxies, while a big 'blob' comprising hundreds of stars appears to be the remnant of a large merger event. These results were published in The Astrophysical Journal Letters on 12 June.
A faint and mysterious stream of microwaves emanating from star systems far out in the Milky Way could be caused by tiny diamonds, new research has suggested.
Global Fishing Watch releases the first-ever 'live' global view of likely transshipping at sea -- a practice that can mask illegal fishing activity, and imagery of night-time fishing and its location, exposing vessels often hidden from other monitoring systems.
NASA's Curiosity Rover discovered 'tough' organic molecules on Mars, increasing the chances that a record of potential life could have been preserved despite harsh conditions that can easily break down organics. Carnegie's Andrew Steele was a key member of the research team, whose work on this project built off his discovery six years ago of indigenous organic carbon in Martian meteorites. The organic molecules he found in 2012 are comparable to those found by Curiosity.
