A powerful M9-class solar flare erupted early Jan. 23 (GMT) has triggered the strongest radiation storm since 2005, NOAA says. The solar flare has also triggered a geomagnetic storm on Earth and could amplify northern lights displays.

Découverte de deux planètes aux dimensions de la Terre | Ciel et Espace

Découverte de deux planètes aux dimensions de la Terre | Ciel et Espace | Astronomy Domain | Scoop.it
Pour le chasseur d'exoplanètes américain Geoffrey Marcy (lire son interview dans notre numéro de janvier, en kiosque le 24 décembre) leur découverte est cependant « beaucoup plus importante » que celle de Kepler-22b il y a deux semaines. « Kepler 20e et 20f sont les premières planètes d'une taille terrestre jamais découverte. Et elles sont presque certainement rocheuses. C'est un moment décisif dans l'histoire de l'humanité » s'enthousiasme le chercheur.

The Umbra of Earth

The Umbra of Earth | Astronomy Domain | Scoop.it

The dark, inner shadow of planet Earth is called the umbra. Shaped like a cone extending into space, it has a circular cross section most easily seen during a lunar eclipse. For example, last Saturday the Full Moon slid across the southern half of Earth's umbral shadow, entertaining moonwatchers around much of the planet. In the total phase of the eclipse, the Moon was completely within the umbra for 51 minutes. Recorded from Beijing, China, this composite eclipse image uses successive pictures from totality (center) and partial phases to trace out a large part of the umbra's curved edge. Background stars are visible in the darker eclipse phases. The result shows the relative size of the shadow's cross section at the distance of the Moon, as well as the Moon's path through Earth's umbra.

A Horseshoe Einstein Ring from Hubble

A Horseshoe Einstein Ring from Hubble | Astronomy Domain | Scoop.it

Explanation: What's large and blue and can wrap itself around an entire galaxy? A gravitational lens mirage. Pictured above, the gravity of a luminous red galaxy (LRG) has gravitationally distorted the light from a much more distant blue galaxy. More typically, such light bending results in two discernible images of the distant galaxy, but here the lens alignment is so precise that the background galaxy is distorted into a horseshoe -- a nearly complete ring. Since such a lensing effect was generally predicted in some detail by Albert Einstein over 70 years ago, rings like this are now known as Einstein Rings. Although LRG 3-757 was discovered in 2007 in data from the Sloan Digital Sky Survey (SDSS), the image shown above is a follow-up observation taken with the Hubble Space Telescope's Wide Field Camera 3. Strong gravitational lenses like LRG 3-757 are more than oddities -- their multiple properties allow astronomers to determine the mass and dark matter content of the foreground galaxy lenses.
