HubbleSite - NewsCenter - NASA's Hubble Spots Rare Gravitational Arc from Distant, Hefty Galaxy Cluster (06/26/2012) - Introduction | Astronomy Domain | Scoop.it

The giant arc is the stretched shape of a more distant galaxy whose light is distorted by the monster cluster's powerful gravity, an effect called gravitational lensing. The trouble is, the arc shouldn't exist.

APOD: 2012 June 9 - Venus at the Edge

APOD: 2012 June 9 - Venus at the Edge | Astronomy Domain | Scoop.it

Explanation: As its June 6 2012 transit begins Earth's sister planet crosses the edge of the Sun in this stunning view from the Hinode spacecraft. The timing of limb crossings during the rare transitswas used historically to triangulate the distance to Venus and determine a value for the Earth-Sun distance called the astronomical unit. Still, modern space-based views like this one show the event against an evocative backdrop of the turbulent solar surface with prominences lofted above the Sun's edge by twisting magnetic fields. Remarkably, the thin ring of light seen surrounding the planet's dark silhouette is sunlight refracted by Venus' thick atmosphere.

Noctilucent Clouds, NLCs

Noctilucent Clouds, NLCs | Astronomy Domain | Scoop.it

Their visibility window extends from mid May to mid August in the Northern Hemisphere. They are best seen at high latitudes of 50 - 65° but are increasingly noticed further south - as here in Hungary. In the New World they have been seen as far south as Utah and Colorado.

Look to the north in a non light polluted sky an hour or more after sunset or before sunrise. They can be distinguished from lower (and dark) tropospheric clouds by their much slower motion and sharp skein-like structure. Binoculars help.

Existe-t-il des alternatives au Modèle du Big Bang ? - Sciences - France Culture

L'univers est-il apparu il y a 13,7 milliards d'années et est-il toujours dans une phase d'expansion accélérée ? Cette conception de l'univers né d'un Big Bang est universellement admise. La majorité des cosmologistes et astrophysiciens partagent cette conception. Pourtant, il existe bel et bien d'autres scénarios possibles sur l'histoire du Cosmos. Reste donc à comprendre les alternatives au modèle standard du Big Bang. Que se soit, par exemple, à travers la question de l’énergie noire, du rôle de certaines constantes, de la nature du rayonnement dit « fossile », ce rendez-vous de Continent Sciences permet de relancer de nouvelles et fascinantes interrogations sur la véritable nature de notre Cosmos.

APOD: 2012 May 24 - All the Water on Europa

APOD: 2012 May 24 - All the Water on Europa | Astronomy Domain | Scoop.it

Explanation: How much of Jupiter's moon Europa is made of water? A lot, actually. Based on the Galileo probe data acquired during its exploration of the Jovian system from 1995 to 2003, Europa posses a deep, global ocean of liquid water beneath a layer of surface ice. The subsurface ocean plus ice layer could range from 80 to 170 kilometers in average depth. Adopting an estimate of 100 kilometers depth, if all the water on Europa were gathered into a ball it would have a radius of 877 kilometers. To scale, this intriguing illustration compares that hypothetical ball of all the water on Europa to the size of Europa itself (left) - and similarly to all the water on planet Earth. With a volume 2-3 times the volume of water in Earth's oceans, the global ocean on Europa holds out a tantalizing destination in the search for extraterrestrial life in our solar system.

All the Water on Planet Earth

All the Water on Planet Earth | Astronomy Domain | Scoop.it

Explanation: How much of planet Earth is made of water? Very little, actually. Although oceans of water cover about 70 percent of Earth's surface, these oceans are shallow compared to the Earth's radius. The above illustration shows what would happen is all of the water on or near the surface of the Earth were bunched up into a ball. The radius of this ball would be only about 700 kilometers, less than half the radius of the Earth's Moon, but slightly larger than Saturn's moon Rhea which, like many moons in our outer Solar System, is mostly water ice. How even this much water came to be on the Earth and whether any significant amount is trappedfar beneath Earth's surface remain topics of research.
