Seven Dusty Sisters
Is this really the famous Pleaides star cluster? Known for its iconic blue stars, thePleaides is shown here in infrared light where the surrounding dust outshines the stars. Here three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6microns). The base images were taken by NASA's orbiting Wide Field Infrared Survey Explorer (WISE) spacecraft. Cataloged asM45 and nicknamed the Seven Sisters, thePleiades star cluster is by chance situated in a passing dust cloud.
Sakurajima Volcano with Lightning
Why does a volcanic eruption sometimes create lightning? Pictured above, theSakurajima volcano in southern Japan was caught erupting in 2013 January. Magma bubbles so hot they glowed shot away as liquid rock burst through the Earth's surface from below.
Opposite the Setting Sun
On April 30, a Full Moon rose opposite the setting Sun. Its yellowish moonglow silhouettes a low tree-lined ridge along Lewis Mountain in this northeastern Alabama skyscape. Sharing the telephoto field-of-view opposite the Sun are Earth's grey shadow, the pinkish Belt of Venus, and bright planet Jupiter. Nearing its own 2018 opposition onMay 8, Jupiter is flanked by tiny pinpricks of light, three of its large Galilean moons.
Hubble's Jupiter and the Shrinking Great Red Spot
What will become of Jupiter's Great Red Spot? Gas giant Jupiter is the solar system's largest world with about 320 times the massof planet Earth. Jupiter is home to one of the largest and longest lasting storm systems known, the Great Red Spot (GRS), visible to the left. The GRS is so large it could swallow Earth, although it has been shrinking
7635: The Bubble Nebula
Blown by the wind from a massive star, this interstellar apparition has a surprisinglyfamiliar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula.
NGC 2023 in the Horsehead's Shadow
Carved by a bright young star in Orion's dusty molecular clouds, NGC 2023 is oftenoverlooked in favor of the nearby dramatic silhouette of the Horsehead Nebula.
The Crab from Space
The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crabis now known to be a supernova remnant, expanding debris from the death explosion of a massive star.
