The aurora similar to the famous orthern Lightson Earth is 10,000 times more powerful than any previously seen.
They found the aurora not from a planet, but from a low-mass star at the boundary between stars and brown dwarfs.
The discovery reveals a major difference between the magnetic activity of more-massive stars and that of brown dwarfs and planets,
18 light-years from Earth, has characteristics unlike any seen in more-massive stars. Brown dwarfs, sometimes called ailed stars,
are objects more massive than planets, yet too small to trigger the thermonuclear reactions at their cores that power stars.
The discovery also has implications for studying extrasolar planets. The aurora the scientists observed from LSR J1835+3259 appears powered by a little-understood dynamo process similar to that seen on larger planets in our Solar system.
This process is different from that which causes the Earth auroral displays the planet magnetic field interacting with the solar wind. hat we see on this object appears to be the same phenomenon wee seen on Jupiter, for example,
but thousands of times more powerful, Hallinan said. his suggests that it may be possible to detect this type of activity from extrasolar planets,

#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.
and cater walls during the summer months on Mars. Eventually these dark streaks dry up as the planet's surface cools in autumn.
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

#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
Sprain and Paul Renne director of the Berkeley Geochronology Center and a UC Berkeley professor-in-residence of earth and planetary science are coauthors of the study
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
Though a magnetic reversal is a major planet-wide event driven by convection in Earth's iron core there are no documented catastrophes associated with past reversals despite much searching in the geologic and biologic record.
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.
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.
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.
--which is better for finding exoplanets. The stars we look at are brightest in the green visible range
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.
