Thanks to orbiters armed with powerful cameras and rovers carrying suites of scientific instruments, the red planet's history is becoming clearer year-by-year. In the past decade or so, evidence of…...
Yes, Mars Once Had an Ocean, says New Research
6+ mon, 1+ week ago (813+ words) Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of Arkansas found strong evidence in Mars' geology of an ocean…...
Mars Didn't Have Bathtubs, It Had Shelves
1+ hour, 31+ min ago (960+ words) Scientists have been debating for decades whether Mars once held a vast ocean covering a large part of its northern face. To prove the idea, they've been looking for a "bathtub ring" - a distinct, level shoreline that shows where water…...
Stellar Flares May Expand Habitable Zones Around Small Stars
8+ hour, 29+ min ago (1149+ words) The search for life beyond Earth has traditionally focused on exoplanets orbiting Sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target for astrobiology, primarily due to…...
