The recent discovery of possible salt water on mars could lead to extraterrestrial life on Mars. NASA's Reconnaissance Orbiter release photos of possible flowing water extending onto a rocky slope. The images show dark colored slim streaks flowing down from slopes and crevices. Brown streaks appear and disappear throughout Mars' winter spring and summer seasons. Briny water has been speculated to be flowing during those seasons.

NASA announced Thursday that they've potentially discovered liquid water on the surface of Mars. Researchers are studying satellite images that appear to have the consistency of salty brine water.

NASA scientists have discovered fresh evidence that water is flowing on Mars during its warmest months, raising the likelihood that life could exist on the red planet, the agency said on Thursday.

NASA's possible water discovery could mean there is life on the red planet. However, one prominent scientist disputes that notion.

Mysterious dark lines discovered on Mars by a search algorithm shows indications of flowing water on the surface today. NASA officials also raised the possibility of how life such as micro-organisms could possibly survive in such an environment.

The images of the findings show flows lengthen and darken on rocky equator-facing slopes from late spring to early fall, and the seasonality, latitude distribution and brightness changes suggest a volatile material is involved, but there is no direct detection of one, NASA said.

The latest findings suggest signs of water in lower latitudes of Mars. Previously, it was known that water (in the form of ice) existed at the poles of the planet.

At one Martian crater, McEwen said, about a thousand ?water flows? were identified.

NASA said it will host a news briefing on Thursday about a significant new Mars science finding. The space agency did not give too many details in the release but said the new finding is based on observations from NASA's Mars Reconnaissance Orbiter (MRO), which has been orbiting the Red Planet since 2006.

U.S. Centers for Disease Control (CDC) continues to investigate the outbreak of Salmonella poisoning that spread across 26 states linked to ground turkey, as a new strain of salmonella highly resistant to the antibiotic Ciprofloxacin surfaces, scientists say.

A recent study published on Wednesday suggests that two strains of Salmonella are resistant to multiple antibiotic treatment drugs as the U.S. Centers for Disease Control and Prevention, along with the U.S. Department of Agriculture?s Food Safety and Inspection Service investigate a multi-state outbreak of Salmonella poisoning linked to ground turkey.
