Salut, j etais en train de delirer sur les images soho ce matin,


je me disais  ; c est impossible je vois jupiter disparaitre vers la droite, c est impossible les planetes tournent dans le meme sens ... puis j ai realisé que nous tournons plus vite que
jupiter autour du soleil et que ce n est que le mouvement apparent .


Ensuite je vois une planete arriver par la gauche mais quand meme bien basse sur l equateur du soleil ! c est venus ? mais alors quid du passage devant le soleil ? soho est il plus haut sur l
ecliptique ? il me semble que sur l orbite de lagrange il fait une sorte de 8 peut etre le fait il en montant et descendant au dessus de l ecliptique ? SDO a une position geostationaire ( il me
semble !? ) peut etre est ce a travers SDO que nous aurons des images ou alors c est carrement depuis la terre ? si quelqu un a des information ?


Hélas, cette fois-ci, le phénomène sera peu visible de France puisque Vénus sortira de devant le disque solaire
à 6h 49 (**).  Si vous voulez profiter du spectacle, dès 6 h du matin installez-vous dans un lieu où l’horizon Est sera bien dégagé et attendez le lever du Soleil qui aura lieu
vers 6 h 20. Vous bénéficierez donc de moins d’une demi heure pour apprécier le spectacle.

campus, for a single flight of stairs.


USDA irrigation research: Good to the last drop

An "unprecedented" surge in debris from last year's Japanese tsunami is washing up on Alaska's coastline, environmentalists about to embark on a major cleanup operation said.


NASA's NuSTAR gearing up for launch
(Phys.org) -- Final pre-launch preparations are underway for NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The mission, which will use X-ray vision to hunt for hidden black holes, is
scheduled to launch no earlier than June 13 from Kwajalein Atoll in the Marshall Islands. The observatory will launch from the belly of Orbital Sciences Corporation's L-1011 "Stargazer" aircraft
aboard the company's Pegasus rocket.

The other end of an eclipse
As the annular eclipse on May 20 sent skywatchers around the globe gazing upwards to see the Sun get darkened by the Moon’s silhouette, NASA’s Terra satellite caught the other side of the event:
the Moon’s shadow striking the Earth!


Extremely rare transit of Venus to occur on June 5, 2012
A few hours before sunset on June 5th, 2012 residents of the Washington, DC metropolitan area will have a chance to witness one of the rarest celestial phenomena known: a “Transit of Venus”.


A planetary system that never was teaches about those that may be
While Kepler and similar missions are turning up planets by the fist full, there’s long been many places that astronomers haven’t expected to find planetary systems. The main places include
regions where gravitational forces conspire to make the region around potential host stars too unstable to form into planets. And there’s no place in the galaxy with a larger gravitational force
than the galactic center where a black hole four and a half million times more massive than the Sun, lurks. But a new study shows evidence that a disk, potentially far enough along to begin
forming planets, is in the process of being disrupted.


Beetle-infested pine trees contribute more to air pollution and haze in forests
The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce
and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS'
journal Environmental Science & Technology.


Nomads of the galaxy
A recent study proposes the galaxy is crowded with nomad planets adrift in space. If this is the case, nomad planets may play a dynamic role in the universe.


Commercial space race gets crowded behind SpaceX
(AP) -- A privately built space capsule that's zipping its way to the International Space Station has also launched something else: A new for-profit space race.


SpaceX capsule completes first tests before ISS docking
The Dragon space capsule, which has launched a new era of commercial spaceflight, completed its first tests before its scheduled docking at the International Space Station, NASA said Wednesday.


TRMM satellite sees heavy rainfall in Tropical Storm Bud
Tropical Storm Bud is dropping heavy rainfall, and appears to be intensifying. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has been monitoring rainfall within the storm, and has
watched it become heavier over the last day - a sign the storm is intensifying.


New satellite movie chases post-Tropical Storm Alberto in Atlantic
On May 23, 2012, the remnants of post-tropical storm Alberto were chasing a frontal system over the Atlantic Ocean, several hundred miles east of the U.S. East coast. A new NASA animation of
imagery from NOAA's GOES-15 satellite shows the progression of Alberto's remnants.


NASA sees Tropical Storm Sanvu continue to intensify
Two NASA satellites have provided infrared and rainfall data that has shown Tropical Storm Sanvu continues to intensify as it heads toward Iwo To, Japan. NASA's Tropical Rainfall Measuring
Mission (TRMM) satellite has scanned rainfall rates, and NASA's Aqua satellite has provided a look at cloud temperatures which indicates where the strongest thunderstorms and heaviest rainfall is
occurring.


'Creeping quakes' rumble New Zealand: researchers
Researchers have discovered New Zealand's earthquake-prone landscape is even more unstable than previously thought, recording deep tremors lasting up to 30 minutes on its biggest fault line.


Dark shadows on Mars: Scene from durable NASA rover
(Phys.org) -- Like a tourist waiting for just the right lighting to snap a favorite shot during a stay at the Grand Canyon, NASA's Mars Exploration Rover Opportunity has used a low sun angle for
a memorable view of a large Martian crater.


Cassini reveals details about charged 'nanograins' near Enceladus
(Phys.org) -- It was a call that Rice University physicist Tom Hill had waited more than 20 years to receive. It traveled almost a billion miles to reach him. And the message — once it arrived
from NASA’s Cassini spacecraft near Saturn — was so enigmatic that it would take another three years to decipher.


Venus Express unearths new clues to the planet's geological history
(Phys.org) -- ESA's Venus Express has been used to study the geology in a region near Venus' equator. Using near-infrared observations collected by the Venus Monitoring Camera (VMC), scientists
have found evidence that the planet's rugged highlands are scattered with geochemically more evolved rocks, rather than the basaltic rocks of the volcanic plains. This finding is in agreement
with previous studies, which used data from the spacecraft's Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) to map the planet's surface in the southern hemisphere.
