#Nasa confirms water on Mars, increasing chance of alien life Mars has long been known as our barren sister planet but today,
NASA scientists have announced they have found flowing water on the red desert planet. NASA and the Nature Geoscience journal released their findings on a Live Stream announcement stating that the long,
dark streaks found on Mars are a telltale sign of still flowing water on the Martian surface.
These dark features, some of which span 5 meters wide and 100 meters long, were discovered originally in 2010.
Over the last few years eight scientists have been analyzing their light signature and now have concluded that the streaks contain mineral salts that easily absorb moisture.
Judging by images of Martian cliffs taken from orbit, NASA scientists theorize the liquid water runs down canyons
and cater walls during the summer months on Mars. Eventually these dark streaks dry up as the planet's surface cools in autumn.
The only question is where does the water come from? Astrologists suggest it may originate from underground water contained in ice or salty aquifers.
Another likely theory could be the water condenses into a liquid from Mars'atmosphere. To this day, Earth is still the only planet in the known universe with liquid H2o on its surface
and so finding out flowing water once exists on Mars is huge. Beyond the geological discovery, dramatically increases our chances of finding extraterrestrial life.
If life On earth is any indication, water is the central building block to all animals, bacteria and everything else alive today y

#Hendo's hoverboard technology could help NASA control satellites Last October, we rode a hoverboard.
microsatellites. Arx Pax is partnering up with NASA to explore how its technology could be used to move around tiny satellites in space using the MFA technology.
It could allow satellites to more safely dock with each other, for example.""Conveniently all satellites and spacecraft are made of aluminum,
which works just fine.""Henderson explains that his hover engine technology works with any conductive surface
which is to say it doesn't have to float over magnets nor utilize superconductors (like the Lexus hoverboard does).
"but conveniently all satellites and spacecraft are made of aluminum, which works just fine.""Speaking of convenience, sound doesn't travel in a vacuum.
In space, that's probably not a problem. The hover engine essentially creates"swirls of electricity"that form magnetic fields both within the hover engine and the conductive surface.
But in space, of course, the concept of"hovering"doesn't really apply. Instead, Arx Pax believes that using its tech to move around tiny objects in space will mean that they won't have to smack into each other
when they need to pair up. Arx Pax plans to co-develop a prototype with NASA over the course of the next couple of years
and chances are it will be pretty small. Cubesats can be as little as 10cm square, and the hover engine also isn't meant to work over large distances either."
"We're talking on the scale of centimeters,"Henderson notes. But in space, smaller pushes can have larger effects over time than they do under gravity.

#Earths magnetic field could flip within a human lifetime Imagine the world waking up one morning to discover that all compasses pointed south instead of north.
Earth's magnetic field has flipped--though not overnight--many times throughout the planet's history. Its dipole magnetic field like that of a bar magnet remains about the same intensity for thousands to millions of years but for incompletely known reasons it occasionally weakens

Flip could affect electrical grid cancer ratesthe discovery comes as new evidence indicates that the intensity of Earth's magnetic field is decreasing 10 times faster than normal leading some geophysicists to predict a reversal within a few

And since Earth's magnetic field protects life from energetic particles from the sun and cosmic rays both
and why Earth's magnetic field episodically reverses polarity Renne said. The magnetic record the Italian-led team obtained shows that the sudden 180-degree flip of the field was preceded by a period of instability that spanned more than 6000 years.
#Rediscovering Venus to find faraway Earths: Measuring gravitational pull of a planet should speed search Astronomers Chih-Hao Li
and David Phillips of the Harvard-Smithsonian Center for Astrophysics want to rediscover Venus--that familiar nearby planet stargazers can see with the naked eye much of the year.
Granted humans first discovered Venus in ancient times. But Li and Phillips have something distinctly modern in mind.
They plan to find the second planet again using a powerful new optical device installed on the Italian National Telescope that will measure Venus'precise gravitational pull on the sun
. If they succeed their first-of-its-kind demonstration of this new technology will be used for finding Earthlike exoplanets orbiting distant stars.
We are building a telescope that will let us see the sun the way we would see other stars said Phillips who is a staff scientist at the Harvard-Smithsonian Center for Astrophysics.
He and Li a research associate at the Center for Astrophysics will describe the device in a paper to be presented at The Optical Society's (OSA) 98th Annual Meeting Frontiers in Optics being held Oct 19-23 in Tucson Arizona USA.
Astronomers have identified more than 1700 exoplanets some as far as hundreds of light years away. Most were discovered by the traditional transit method
when a planet orbiting a distant star transits that luminous body moving directly between the Earth
and the star This provides information about the planet's size but not its mass.
which offers complementary information about the mass of the distant planet. From this information astronomers will be able to determine
whether distant exoplanets they discover are rocky worlds like Earth or less dense gas giants like Jupiter.
The method is precise enough to help astronomers identify Earthlike planets in the habitable zone the orbital distance sweet-spot where water exists as a liquid.
Better Precision with a Laserthe radial velocity method works by measuring how exoplanet gravity changes the light emitted from its star.
As exoplanets circle a star their gravitation tugs at the star changing the speed with
which it moves toward or away from Earth by a small amount. The star speeds up slightly as it approaches Earth with each light wave taking a fraction of a second less time to arrive than the wave before it.
To an observer On earth the crests of these waves look closer together than they should so they appear to have a higher frequency and look bluer.
As the star recedes the crests move further apart and the frequencies seem lower and redder.
This motion-based frequency change is known as the Doppler shift. Astronomers measure it by capturing the spectrum of a star on the pixels of a digital camera
and watching how it changes over time. Today's best spectrographs are only capable of measuring Doppler shifts caused by velocity changes of 1 meter per second or more.
Only large gas giants or super-earths close to their host stars have enough gravity to cause those changes.
however will be able to detect Doppler shifts as small as 10 centimeters per second--small enough to find habitable zone Earthlike planets even from hundreds of light years away.
This way we can compare data we take tonight with data from the same star five years from now
Their new version of the astro-comb lets astronomers measure green light --which is better for finding exoplanets.
The stars we look at are brightest in the green visible range and this is the range spectrographs are built to handle Phillips said.
Building the green astro-comb was a challenge since the researchers needed to convert red laser light to green frequencies.
The researchers plan to test the green astro-comb by pointing it at our sun analyzing its spectrum to see
when we point our spectrographs at distant stars Li said. The Harvard-Smithsonian team is installing this device on the High-Accuracy Radial Velocity Planet Searcher-North (HARPS-N) a new spectrograph designed to search for exoplanets using the Italian National Telescope.
We will look at the thousands of potential exoplanets identified by the Kepler satellite telescope by the transit method.
Together our two methods can tell us a lot about those worlds Li said. And because he will have discovered already Venus he will be more certain of the answers s
#Is matter falling into the massive black hole at the center of the Milky way or being ejected from it?
Is matter falling into the massive black hole at the center of the Milky way or being ejected from it?
but a UC Santa barbara astrophysicist is searching for an answer. Carl Gwinn a professor in UCSB's Department of physics and colleagues have analyzed images collected by the Russian spacecraft Radioastron.
Their findings appear in the current issue of The Astrophysical Journal Letters. Radioastron was launched into orbit from Baikonur Kazakhstan in July 2011 with several missions one
of which was to investigate the scattering of pulsars--the cores of dead stars--by interstellar gas.
What the team found led them to examine additional observations of Sagittarius A-Star (A*)the source that marks the Milky way's central black hole.
Sagittarius A is visible at radio infrared and X-ray wavelengths. This massive black hole--which contains 4 million solar masses--does not emit radiation
but is visible from the gas around it. The gas is being acted upon by the black hole's very strong gravitational field.
The wavelengths that make Sagittarius A*visible are scattered by interstellar gas along the line of sight in the same way that light is scattered by fog On earth.
Gwinn and his colleagues found that the images taken by Radioastron contained small spots. I was surprised quite to find that the effect of scattering produced images with small lumps in the overall smooth image explained Gwinn.
In order to better understand the substructure Michael Johnson Gwinn's former graduate student now at the Harvard-Smithsonian Center for Astrophysics conducted theoretical research.
--and the 100-meter Green Bank Telescope in West virginia showed the presence of lumps in the image of Sagittarius A*.Recent upgrades have increased greatly the sensitivity of these telescopes.
The theory and observations allow us to make statements about the interstellar gas responsible for the scattering
and about the emission region around the black hole Johnson said. It turns out that the size of that emission region is only 20 times the diameter of the event horizon as it would be seen from Earth.
With additional observations we can begin to understand the behavior in this extreme environment. While no scientific team has been able to produce a complete image of the black hole's emission astronomers have drawn inferences about scattering properties from observations at longer wavelengths.
From these they can extrapolate those properties to 1 centimeter and use that to make a rough estimate of the size of the source Gwinn said.
and his colleagues directly confirm these indirect inferences about the size of Sagittarius A*they were also able to provide new information about fluctuations in the interstellar gas that cause scattering.
This will be important for future research on the gas near this black hole. This work is a good example of the synergy between different modern research infrastructures technologies and science ideas.
A friendly international race is going on to see who will be the first to image the black hole's emissions
whether gas falls into the black hole or is being ejected in the form of a jet.
and we can get closer to the black hole. We may be able to extract more information than just the size of the emission region.
We might possibly be able to make a simple image of how matter falls into a black hole
and reduce carbon dioxide emissions on the earth Shimoi said. Story Source: The above story is provided based on materials by American Institute of Physics (AIP.
#Solar activity impacts polar ozone The increase in greenhouse gases explains to a large extent the rise in the average temperature of Earth.
According to the research study published in Nature Communications today the Sun affects middle atmosphere ozone with potential implications on smaller scale to regional but not global climate.
Humankind is responsible for the global warming of our climate by increasing the amount of greenhouse gases in the atmosphere.
However according results published today fluctuations in the activity of the Sun impact middle atmosphere ozone providing a potential link to regional scale climate variability.
This climate variability is not a trend like climate change but rather year-to-year fluctuations following solar activity.
The detected ozone variation may in part help understand the alternation of local mild and cold winter seasons as hints have been obtained in previous research that the ozone changes in the middle atmosphere may link as far as the surface of Earth
The research team was able to confirm for the first time the long-term implications of solar-driven electron impact on the upper middle atmosphere ozone.
The ozone variation between the extremes of the Sun's activity is so great that it is likely to impact the temperature balance of the atmosphere.
Electrons from space: Auroras and ozone lossaccording to the research study conducted by the Finnish Meteorological Institute University of Otago
and The british Antarctic Survey the electrons similar to those behind the aurora cause significant solar cycle variation in the polar mesosphere ozone.
The amount of ozone is smaller when more electrons enter the atmosphere. These results are only the first step
but an important one allowing us to better understand the long-term impacts of this type of solar activity
and its role in regional climate variability says Dr Monika Andersson who lead the study at Finnish Meteorological Institute.
Earth's radiation belts are regions in near-Earth space that contain vast quantities of solar energetic electrons trapped there by Earth's magnetic field.
During magnetic storms which are driven solar wind the electrons accelerate to high speeds and enter the atmosphere in the polar regions.
In the atmosphere the electrons ionize gas molecules leading to the production of ozone-depleting catalyst gases.
Based on currently available satellite observations electron precipitation may during solar storms lasting a few days reduce ozone in the upper atmosphere (60-80 km) as much as 90 per cent on a momentary basis

Over the years scientists have been very successful at making complex 3d shapes from DNA using diverse strategies said Wei Sun a postdoctoral scholar in the Wyss'Molecular Systems Lab

The concept can be likened to the Japanese method of growing watermelons in glass cubes. By nurturing watermelon seeds to maturity inside cube-shaped glass boxes Japanese farmers create cube-shaped mature melons that allow for densely-packed shipping and storage of the fruit.

Along with gravity the electromagnetic interaction and weak nuclear force strong-interactions are one of four fundamental forces. Lead scientist Professor Tim Gershon from The University of Warwick's Department of physics explains:
Gravity describes the universe on a large scale from galaxies to Newton's falling apple whilst the electromagnetic interaction is responsible for binding molecules together
and also for holding electrons in orbit around an atom's nucleus. The strong interaction is the force that binds quarks the subatomic particles that form protons within atoms together.
It is so strong that the binding energy of the proton gives a much larger contribution to the mass through Einstein's equation E=mc2 than the quarks themselves. 3 Due in part to the forces'relative simplicity scientists have previously been able to solve the equations behind gravity
why there is more matter than antimatter in the Universe. Notes 1 The Ds3*(2860) particle is a meson that contains a charm antiquark and a strange quark.
