Curiosity finds evidence of a daily water cycle on Mars

Science Focus

original post »

A huge range of data indicates that water has played a key part in the history of Mars, from entire oceans in the distant past, to evidence of lakes and streams at the landing site of the Curiosity rover. But what has not been clear is the role that water plays on the planet now. Hints of water activity have been spotted from orbit, but direct detection of liquid water on the surface has been elusive.

This week, a scientific team using data from the Curiosity rover has announced a bit more indirect evidence. Based on a combination of data about Martian weather and soil conditions, the researchers conclude that salts found on Mars can pull water out of the thin atmosphere and may drive a daily water cycle. While the evidence is indirect, it's consistent with data from a Russian instrument that registers indications of water molecules in the soil.

One of the more common chemicals in the Martian soil appears to be perchlorate salts, which have been detected from orbit and found by the Phoenix lander. These salts—calcium perchlorate in particular—readily form hydrates, where water molecules are integrated into the crystal structure itself to form an energetically favorable conformation. On Earth, this transition is so favorable that the salts can readily pull water out of the air on humid days.

Team tightens bounds on quantum information 'speed limit'

more »

If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards and Technology have narrowed the theoretical limits for where that "speed limit" is. The research implies that quantum processors will work more slowly than some research has suggested.

A blueprint for clearing the skies of space debris

more »

Scientists have put forward a blueprint for a purely space-based system to solve the growing problem of space debris. The proposal will be used to detect objects, and a recently developed high-efficiency laser system will be used to track space debris and remove it from orbit.

M46 Plus Two

more »
Galactic or open star clusters are young. These swarms of stars are born together near the plane of the Milky Way, but their numbers steadily dwindle as cluster members are ejected by galactic tides and gravitational interactions. In fact, this bright open cluster, known as M46, is around 300 million years young. It still contains a few hundred stars within a span of 30 light-years or so. Located about 5,000 light-years away toward the constellation Puppis, M46 also seems to contain contradictions to its youthful status. In this pretty starscape, the colorful, circular patch above and right of the center of M46 is the planetary nebula NGC 2438. Fainter still, a second planetary nebula, PK231+4.1, is identified by the box at the right and enlarged in the inset. Planetary nebulae are a brief, final phase in the life of a sun-like star a billion years old or more, whose central reservoir of hydrogen fuel has been exhausted. NGC 2438 is estimated to be only 3,000 light-years distant, though, and moves at a different speed than M46 cluster members. Along with its fainter cohort, planetary nebula NGC 2438 is likely only by chance appearing near our line-of-sight to the young stars of M46.

Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.
