On the 12th of April 2017, the Cassini spacecraft orbiting Saturn took a minute to look back towards its home planet and snap a picture. At the time, the Earth, Moon, and all 7.125 billion humans were about 1.8 billion kilometers away. The fortuitous image catches Earth sitting between the A and F rings of Saturn, with the Keeler and Encke gaps visible as well. Cassini hasn't taken many pics of home, but this is probably my favourite so far.
On 22 April 2017, Cassini will take a gravity assist from Saturn's largest moon Titan and start the first of 22 orbits that slowly bring it closer to the cloud-tops of the gas giant. In September, this intrepid spacecraft will burn up in its atmosphere, but it's legacy will live on.

Une image de Saturne captée au-dessus de son pôle Nord, avec ses anneaux (credit d'image: NASA).
Le 12 avril 2017, l’astronef Cassini en orbite autour de Saturne a pris un moment pour se tourner vers sa planète et prendre une photo. À ce moment, la Terre, la Lune et les 7,125 milliards d’humains se trouvaient à environ 1,8 milliard de kilomètres. L’image inopinée capte la Terre entre les anneaux A et F de Saturne avec les divisions de Keeler et d’Encke également visibles. Cassini n’a pas pris beaucoup de photos de la Terre et celle-ci est probablement ma préférée jusqu’à maintenant.
Le 22 avril 2017, Cassini profitera de l’assistance gravitationnelle de la plus grande lune de Saturne, Titan, et commencera la première orbite de 22 qui le rapprocheront lentement du sommet des nuages de la géante gazeuse. En septembre, l’intrépide astronef brûlera dans son atmosphère, mais son héritage demeurera.

Two spiral galaxies: NGC 4302 and 4298 (image credit: NASA).
On the 24th of April, 1990, the Hubble Space Telescope (HST) was launched into Earth orbit. After a bit of a rocky start, HST soon became one of the most important telescopes humans have ever built. Over its 27 years in orbit it has helped shape and guide our understanding of the Universe; from measuring the furthest galaxies to imaging smashed asteroids in the belt between Jupiter and Mars, it has contributed to many of the current astronomical fields.
For its birthday each year, HST releases a new 'spectacular image' to celebrate. This year, the image is of the two spiral galaxies NGC 4302 and 4298 (the 4302nd and 4298th galaxies in the New General Catalogue). Looking forward to many more insights from HST!

Deux nébuleuses spirales : NGC 4302 et NGC 4298 (credit d'image: NASA).
Le 24 avril 1990, le télescope spatial Hubble (TSH) a été mis en orbite terrestre. Après un mauvais départ, le TSH est rapidement devenu l’un des plus importants télescopes jamais construits. Durant ses 27 années en orbite, il a aidé à façonner et à orienter notre compréhension de l’univers. Qu’il s’agisse d’évaluer la distance des galaxies les plus éloignées ou de produire des images d’astéroïdes fracassés dans la ceinture entre Jupiter et Mars, le télescope a contribué à de nombreux domaines de l’astronomie actuelle.
Chaque année, pour son anniversaire, le TSH diffuse une nouvelle « image spectaculaire » à célébrer. Cette année, l’image présente deux nébuleuses spirales NGC 4302 et NGC 4298 (soit les 4 302e et 4 298e galaxies du New General Catalogue). Nous avons hâte de voir d’autres images produites par le TSH!

Astronomers have found an exoplanet that has the right conditions for liquid water on its surface image credit: ESO).
A newly discovered exoplanet, LHS 1140b, is being called the "best place to look for signs of life beyond the Solar System." The reason is because of a confluence of factors: the planet is likely rocky, orbits a relatively quiet star, passes in-front of its star from Earth's point-of-view every 25 days, and likely has an atmosphere. At the moment, studying that atmosphere in detail is not possible; however, with the next generation of telescopes coming online in the coming years (TMT, ELT, JWST), exoplanet atmospheres will become the new science.
At the moment, we know of over 3500 planets orbiting stars other than the Sun; check out exoplanet.eu for up-to-date information.

Des astronomes ont trouvé une exoplanète qui réunit les bonnes conditions pour la présence d’eau liquide à sa surface (crédit d’image: ESO)
Baptisée LHS 1140b, une exoplanète nouvellement découverte reçoit le titre de « meilleure candidate pour la recherche de traces de vie au-delà du système solaire ». C’est qu’en raison d’une multitude de facteurs, l’exoplanète est constituée de roches, tourne autour d’une étoile relativement calme, passe devant son étoile tous les 25 jours – du point de vue de la Terre – et possède probablement une atmosphère. Actuellement, nous ne pouvons observer cette atmosphère en détail. Toutefois, lorsque de nouveaux télescopes (le Télescope de trente mètres, l’Extremely Large Telescope, le télescope spatial James-Webb) entreront en service dans les années à venir, l’étude de l’atmosphère des exoplanètes deviendra la nouvelle science.
À l’heure actuelle, plus de 3 500 planètes ont été détectées autour d’étoiles autres que le Soleil. Visitez le site Web exoplanet.eu pour obtenir des renseignements à jour.

NASA releases new images of Earth at night (image credit: NASA).
NASA has released new composite images of the Earth at night. The images were all taken with the VIIRS instrument aboard the Suomi NPP satellite (an imager that orbits around Earth's poles). While the images are breathtaking, I'm more excited for what's coming next: later this year, NASA will be releasing DAILY data dumps from the night lights project. Meaning... scientists/anyone will be able to study the light/energy uses around the globe on a daily basis.
I love data.

La NASA diffuse de nouvelles images de la Terre la nuit (credit d'image: NASA).
La NASA a publié des images composites de la Terre la nuit. Les images ont toutes été captées à l’aide de l’instrument VIIRS à bord du satellite Suomi NPP (un imageur orbitant les pôles de la Terre). Bien que les images soient époustouflantes, j’ai davantage hâte à ce qui va suivre : plus tard cette année, la NASA publiera des vidages de données QUOTIDIENNES du projet de lumières nocturnes. C’est-à-dire que les scientifiques (ou n’importe qui) pourront étudier l’utilisation de lumières/d’énergie partout dans le monde sur une base quotidienne.
J’adore les données.

The Cassini spacecraft is beginning its Grand Finale, a final tour of Saturn (image credit: NASA/JPL).
A short description of the upcoming Grand Finale of the Cassini Spacecraft. Over the next 5 months, Cassini will make 22 plunges between Saturn's rings and the planet itself. No craft has ever been that close. During this final phase, Cassini will make close up measurements of the rings for the first time, image the planet's cloud-tops in unprecedented detail, and even answer long-standing questions like: how fast does Saturn actually rotate?
It's going to be a very interesting 5 months.

L’astronef Cassini entame sa grande finale, un dernier tour de Saturne (credit d'image: NASA/JPL).
Une courte description de l’imminente grande finale de l’astronef Cassini. Au cours des cinq prochains mois, Cassini effectuera 22 plongeons entre Saturne et ses anneaux. Aucun engin spatial ne s’est jamais rendu aussi proche. Durant cette dernière phase, Cassini prendra des mesures de très près des anneaux pour la première fois et des photos détaillées comme jamais du sommet des nuages de la planète. Il répondra même à des questions qu’on se pose depuis longtemps, comme la vitesse de rotation actuelle de Saturne.
Les cinq prochains mois seront très intéressants.
