By starlight, this eerie visage shines in the dark with a crooked profile evoking its popular name, the Witch Head Nebula. In fact, this entrancing telescopic portrait gives the impression that a witch has fixed her gaze on Orion’s bright supergiant star Rigel. More formally known as IC 2118, the Witch Head Nebula spans about […]
NASA test pilot Joe Walker took the Lunar Landing Research Vehicle (LLRV) for its first spin 60 years ago today. NASA used the LLRV, also known as the flying bedstead, to train Apollo astronauts for the descent to the Moon’s surface. via NASA https://ift.tt/RKYkQLw
What created this huge space bubble? Blown by the wind from a star, this tantalizing, head-like apparition is cataloged as NGC 7635, but known simply as the Bubble Nebula. The featured striking view utilizes a long exposure to reveal the intricate details of this cosmic bubble and its environment. Although it looks delicate, the 10 […]
New Zealand’s stunning scenery has famously provided the backdrop for fictional worlds in fantasy films. A unique cloud that forms over the Otago region of the country’s South Island also evokes the otherworldly, while very much existing in reality. via NASA https://ift.tt/tiO8ncE
The stars are destroying the pillars. More specifically, some of the newly formed stars in the image center are emitting light so energetic that is evaporating the gas and dust in the surrounding pillars. Simultaneously, the pillars themselves are still trying to form new stars. The whole setting is the star cluster NGC 602, and […]
Space science is fun! NASA astronaut and Expedition 72 Flight Engineer Don Pettit fills this sphere of water with food coloring creating a Jupiter-like effect in the microgravity environment of the International Space Station. via NASA https://ift.tt/tzEDogV
Sometimes a river of hot gas flows over your head. In this case the river created a Strong Thermal Emission Velocity Enhancement (STEVE) that glowed bright red, white, and pink. Details of how STEVEs work remain a topic of research, but recent evidence holds that their glow results from a fast-moving river of hot ions […]
What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic batflying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background […]
These brightly outlined flowing shapes look ghostly on a cosmic scale. A telescopic view toward the constellation Cassiopeia, the colorful skyscape features the swept-back, comet-shaped clouds IC 59 (left) and IC 63. About 600 light-years distant, the clouds aren’t actually ghosts. They are slowly disappearing though, under the influence of energetic radiation from hot, luminous […]
The spiral galaxy in this NASA/ESA Hubble Space Telescope image is IC 3225. It looks remarkably as if it was launched from a cannon, speeding through space like a comet with a tail of gas streaming from its disk behind it. via NASA https://ift.tt/aoLPjbX
