New research shows that the Martian meteorite Northwest Africa (NWA) 7034, known more commonly as ‘Black Beauty,’ was ejected between 5 and 10 milliom years ago from a crater in the north-east of the Terra Cimmeria-Sirenum province in the southern hemisphere of Mars. NWA 7034, approximately 320 grams in weight, is a regolith breccia from […] The post Planetary Scientists Identify Home Crater of Famous Martian Meteorite appeared first on Sci.News: Breaking Science News ..read more

Geologists have discovered 1.2-billion-year-old groundwater about 3 km below surface in Moab Khotsong, a gold- and uranium-producing mine in South Africa. This ancient groundwater is enriched in the highest concentrations of radiogenic products yet discovered in fluid. The discovery have implications beyond Earth, where on rocky planets such as Mars, subsurface water may persist on long […] The post 1.2-Billion-Year-Old Groundwater System Found in South African Mine appeared first on Sci.News: Breaking Science News ..read more

Hackmanite, tugtupite, and scapolite change their color from white to purple, pink, and blue, respectively, under UV irradiation, according to a team of scientists from the University of Turku. “Color-changing minerals are inorganic natural materials, but there are also organic compounds, hydrocarbons, that can change color reversibly due to exposure to radiation,” said Professor Mika […] The post Natural Aluminosilicate Minerals Change Color Under UV Light appeared first on Sci.News: Breaking Science News ..read more

Using neutron and X-ray tomography, a team of planetary researchers from Lund University and elsewhere examined a section of Miller Range (MIL) 03346, a nakhlite meteorite from Miller Range in Antarctica. Nakhlites are a group of igneous Martian meteorites that are rich in minerals called pyroxene and olivine. One key finding in these meteorites is […] The post 1.3-Billion-Year-Old Martian Meteorite Had Limited Exposure to Water, Study Finds appeared first on Sci.News: Breaking Science News ..read more

Scientists from West Virginia University have found ancient cells of prokaryotes and eukaryotes within fluid inclusions in halite crystals from the Neoproterozoic Browne Formation in central Australia. “As halite crystals grow in saline surface waters, it traps parent water in primary fluid inclusions,” said Sara Schreder-Gomes and her colleagues from the Department of Geology and […] The post 830-Million-Year-Old Microorganisms Found in Australian Halite appeared first on Sci.News: Breaking Science News ..read more

Named Lake Snow Eagle, the newly-discovered subglacial lake is approximately 42 km in length and 370 km2 in area, making it one of the largest subglacial lakes in Antarctica. Revealed by heavily instrumented polar research aircraft, Lake Snow Eagle is lies in a km-deep canyon in the highlands of Princess Elizabeth Land, a few hundred […] The post Huge Subglacial Lake Discovered in East Antarctica appeared first on Sci.News: Breaking Science News ..read more
