Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45.

The Flame Nebula, also called NGC 2024, is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. It’s a part of the Orion Molecular Cloud Complex.

his close-up picture of a Zvezda Service Module array, reflecting bright rays of the sun, thus creating an artistic scene, was photographed on April 3 by one of the Expedition 35 crew members as part of an External Survey from International Space Station windows that was recently added to the crew's task list.

The Soyuz rocket is rolled out to the launch pad by train on Tuesday, March 26, 2013, at the Baikonur Cosmodrome in Kazakhstan. Launch of the Soyuz rocket is scheduled for March 29.

On March 21, 2013, the P-3B aircraft waits outside the hangar at Thule Air Base with the Greenland Ice sheet in the background. IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice.

JSC2013-E-017269 (16 March 2013) -- The Soyuz TMA-06M spacecraft lies passively on its side March 16 after bringing home Expedition 34 Commander Kevin Ford of NASA, Soyuz Commander Oleg Novitskiy and Flight Engineer Evgeny Tarelkin to a landing northeast of Arkalyk, Kazakhstan following a one-day delay due to inclement weather in the area.

What caused this outburst of V838 Mon? For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before.

Puffy white exhaust contrails stream from the engines of NASA's DC-8 flying laboratory in this image taken from an HU-25 Falcon flying about 300 feet behind. NASA researchers have begun a series of flights using the agency's DC-8 to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude.

NASA engineer Chip Holloway waits for the sun to align with the Stratospheric Aerosol and Gas Experiment (SAGE III) during a clean room "sun-look" test on March 4, 2013, at NASA's Langley Research Center in Hampton, Va. SAGE III passed this test, successfully locking onto the sun and completing a series of measurements.

The gravitational field surrounding this massive cluster of galaxies, Abell 68, acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies.The image of a spiral galaxy at upper left has been stretched and mirrored into a shape like a simulated alien from the computer game "Space Invaders!"

Saturn's north polar hexagon basks in the Sun's light now that spring has come to the northern hemisphere. Many smaller storms dot the north polar region and Saturn's signature rings, which appear to disappear on account of Saturn's shadow, put in an appearance in the background.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface.

Technicians encapsulate NASA's Landsat Data Continuity Mission (LDCM) satellite in its payload fairing in the Astrotech processing facility at Vandenberg Air Force Base in California.

The United Launch Alliance (ULA) Atlas-V rocket with the Landsat Data Continuity Mission (LDCM) spacecraft onboard is seen as it launches on Monday, Feb. 11, 2013 at Vandenberg Air Force Base, Calif. The Landsat Data Continuity Mission (LDCM) mission is a collaboration between NASA and the U.S. Geological Survey.

The Orion nebula is featured in this sweeping image from NASA's Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The nebula (also catalogued as Messier 42) is located in the sword of Orion.

This esthetic close-up of cosmic clouds and stellar winds features LL Orionis, interacting with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged Sun.

The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation.

The ring-region Saturnian moons Prometheus and Pan are both caught "herding" their respective rings in this image. Through their gravitational disturbances of nearby ring particles, one moon maintains a gap in the outer A ring and the other helps keep a ring narrowly confined.

ISS034-E-016601 (4 Jan. 2013) -- On Jan. 4 a large presence of stratocumulus clouds was the central focus of camera lenses which remained aimed at the clouds as the Expedition 34 crew members aboard the International Space Station flew above the northwestern Pacific Ocean about 460 miles east of northern Honshu, Japan.

The Milky Way and other galaxies in the universe harbor many young star clusters and associations that each contain hundreds to thousands of hot, massive, young stars known as O and B stars. The star cluster Cygnus OB2 contains more than 60 O-type stars and about a thousand B-type stars.

Technicians and scientists check out one of the Webb telescope's first two flight mirrors on Sept. 19, 2012 in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md. The mirrors are going through receiving and inspection and will then be stored in the Goddard clean room until engineers are ready to assemble them.

Un long silence s'est abattu sur la Corée du Sud, alors que plus d'un demi million d'élèves passaient un important examen d'entrée à l'université. Les autorités ont pris des mesures drastiques pour en assurer le bon déroulement
 
Afin de limiter toute perturbation, les autorités ont pris des mesures drastiques : les administrations, les banques et la bourse ont ouvert une heure plus tard que d'habitude pour faciliter la circulation et permettre aux étudiants d'arriver à l'heure pour l'examen  
 
Tous les décollages et atterrissages dans les aéroports du pays ont été suspendus 35 minutes pendant un test d'écoute d'anglais. Et tous les avions en vol ont dû maintenir une altitude supérieure à 3.000 mètres  
 
Selon le ministère des Transports, 79 vols ont été reprogrammés en raison de l'examen. Des voitures et motos de police étaient disponibles dans les zones scolaires pour les élèves coincés dans le trafic ou en retard.
 
La pression énorme qu'exerce sur les jeunes étudiants le système éducatif ultra-compétitif de la Corée du Sud a souvent été décriée.  
Pour ses détracteurs, il est à l'origine des taux - parmi les plus élevés au monde - de dépressions et de suicides chez les adolescents  
 
Au lycée pour filles Ewha, dans le centre de Séoul, certains candidats sont arrivés tenant la main de leurs parents, visiblement nerveux. À l'extérieur de l'école, certaines personnes ont été vues en train de prier ou de prendre des selfies

en france, pendant les épreuves du bac, la ratp se met en grève. Deux mondes.
 
J'ai passé mon brevet de francais en juin avec 1 marteau piqueur sous la fenêtre...
 
Nous sommes tellement loin de cet état d'esprit
