Hydrothermal Vents on Mars Could Have Supported Life Posted: 6 months ago by AutumnLotus

Ancient bacteria could point to life on Mars: study Posted: 1 year ago by AutumnLotus
Ancient bacteria are able to survive nearly half a million years in harsh, frozen conditions, researchers said on Monday in a study that adds to arguments that permafrost environments on Mars could harbor life.

Wow! Newest Mars probe photographs rover Opportunity from Mars orbit Posted: 2 years ago by Fanatic
The Mars Reconnaissance Orbiter has just begun its science mission, and one of the first targets is Victoria Crater, where the rover Opportunity has just arrived after nearly 1000 sols on Mars.
The photos, using the largest interplanetary telescope ever lofted, are truly amazing.
See comments for links to original imagery.

Sun's Temper Blamed for Loss of Water on Mars Posted: 1 year ago by AutumnLotus
Mars was wet in its early history, but today it appears bone dry other than ice below the surface and at the poles. Astronomers have long wondered where all the water went. The water might have been blown into space long ago by strong gusts of solar winds, new satellite observations suggest.

Building blocks of life formed on Mars Posted: 12 months ago by AutumnLotus
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impacts or more speculatively originated from ancient Martian microbes.

New Discovery on Mars: Ephemeral Polar Water Ice Mapped Posted: 10 months ago by AutumnLotus
After decades of studying the climate conditions of Mars, scientists have recently made a breakthrough observation. Adrian Brown's team found a substantial amount of ephemeral (short lived) water ice in the polar regions of Mars.

Scientists discover signs of ancient life on Mars Posted: 9 months ago by AutumnLotus
For the first time, satellite imagery reveals thick Martian salt deposits scattered across the planet's southern surface, which one planetary scientist claims could be sites of ancient life. The mats of sodium chloride — the same taste-enhancing mineral found on your kitchen table — serve as more evidence of Mars' watery past, and researchers think the briney pools that made them could have been hospitable to life.

Liquid crystal phases of tiny DNA molecules point up new scenario for first life on Earth Posted: 1 year ago by AutumnLotus
A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth.

Mars: a once habitable environment? Posted: 12 months ago by tundramonkey
Spirit and Opportunity, the NASA Mars Rovers, have discovered interesting features that suggest Mars could have supported life at one time, including 'rivers' of frozen carbon dioxide that flow uphill.

Hope for Water on Mars Dims with Sharp New Images Posted: 1 year ago by AutumnLotus
New images obtained by a sharp-eyed Martian satellite reveal that some Red Planet features once thought to have been carved by flowing water were in fact created by other processes.

Bottled Water - Where Does That Water Come From? Posted: 2 years ago by AutumnLotus
The economic value of "special water" was first cultivated in Europe during the late 1700s when people began visiting natural springs to drink the water or bathe in it. Then in 1767, Jackson's spa in Boston began bottling their water.

Fire and Brimstone Helped Form Mars Oceans Posted: 12 months ago by AutumnLotus
The longstanding mystery of how oceans once formed on Mars could be solved by fire and brimstone. Specifically, researchers now suggest that ancient volcanoes could have released brimstone — now more commonly known as sulfur — that warmed up the red planet enough for liquid water oceans in the early days of Mars. These findings might also shed insight on the young Earth, including the origins of life.

Huge reservoir of frozen water discovered on Mars Posted: 2 years ago by BrownTrout
