How about another picture from Milford Sound? Again, lucky timing with the moon right there over Mitre Peak.

ブラックホールが「星を破壊して飲み込む瞬間」をNASAが公開(動画あり)

On the night of Oct. 8, a photographer in Harstad, Norway captured this image of the dancing northern lights. Auroras are created when fast-moving, magnetic solar material strikes Earth's magnetic bubble, the magnetosphere. This collision rattles the magnetosphere in an event called a geomagnetic storm, sending trapped charged particles zooming down magnetic field lines towards the atmosphere, where they collide brilliantly with molecules in the air, creating auroras. Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind. "Geomagnetic storms caused by high-speed solar wind streams aren't uncommon," said Leila Mays, a space physicist at our Goddard Space Flight Center in Greenbelt, Maryland. "Near solar minimum-when solar activity like CMEs are less frequent-these fast streams are actually the most common cause of geomagnetic storms that create auroras."

銀河から噴き出す真紅の光 - ギャラリー

すばる望遠鏡FOCASで撮影した不規則銀河、M82。左上から右下に伸びる青白い光は星の分布を表し、それと垂直な方向に広がる赤い光は、銀河の中心部で起きている活発な星生成活動によって噴き出された電離ガスを見ています。このように銀河からガスが吹き飛ばされる現象は銀河の進化に大きな影響を与えると考えられて …

This Hubble Space Telescope picture shows a galaxy named SBS 1415+437 (also called SDSS CGB 12067.1), located about 45 million light-years from Earth. SBS 1415+437 is a Wolf-Rayet galaxy, a type of star-bursting galaxy with an unusually high number of extremely hot and massive stars known as Wolf-Rayet stars. These stars can be around 20 times as massive as the sun, but seem to be on a mission to shed surplus mass as quickly as possible - they blast substantial winds of particles out into space, causing them to dwindle at a rapid rate. A typical star of this type can lose a mass equal to that of our sun in just 100,000 years! Image credit: ESA/Hubble & NASA #nasa hubble #hst #hubble25 #space #galaxy #astronomy #science
