Thor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor’s Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages. Heroically sized even for a Norse god, Thor’s Helmet is about 30 light-years across. In fact, the cosmic head-covering is more like an interstellar bubble, blown with […]
This image from the NASA/ESA Hubble Space Telescope features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (very close at its left) respectively; and finally, IC 1947 […]
Venus goes through phases. Just like our Moon, Venus can appear as a full circular disk, a thin crescent, or anything in between. Venus, frequently the brightest object in the post-sunset or pre-sunrise sky, appears so small, however, that it usually requires binoculars or a small telescope to clearly see its current phase. The featured […]
To some it looks like a cat’s eye. To others, perhaps like a giant cosmic conch shell. It is actually one of the brightest and most highly detailed planetary nebula known, composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star. This nebula’s dying central star […]
You couldn’t really be caught in this blizzard while standing by a cliff on periodic comet 67P/Churyumov-Gerasimenko. Orbiting the comet in June of 2016, the Rosetta spacecraft’s narrow angle camera did record streaks of dust and ice particles similar to snow as they drifted across the field of view close to the camera and above […]
Expedition 70 NASA astronaut Loral O’Hara has her Russian Sokol spacesuit pressure checked ahead launching to the International Space Station with fellow crewmates, Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub, Friday, Sept. 15, 2023 in Baikonur, Kazakhstan. via NASA https://ift.tt/ijF7gZU
Near the center of this sharp cosmic portrait, at the heart of the Orion Nebula, are four hot, massive stars known as the Trapezium. Gathered within a region about 1.5 light-years in radius, they dominate the core of the dense Orion Nebula Star Cluster. Ultraviolet ionizing radiation from the Trapezium stars, mostly from the brightest […]
Amazonian leaders visit “Space for Earth,” an immersive audio-visual installation that draws from near real-time satellite data and images, in NASA’s Earth Information Center at the NASA Headquarters Mary W. Jackson Building in Washington on Nov. 17, 2023. via NASA https://ift.tt/ADh7dFq
Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait. In the false-color view, bluish Zeta Oph, a star about 20 times more massive than the Sun, lies near the center of the frame, moving toward the left at […]
NASA astronauts Kjell Lindgren, Jessica Watkins, and Robert Hines participate in STEM demonstrations with local students at the Martin Luther King Jr Memorial Library, Thursday, March 30, 2023, in Washington. Lindgren, Hines, and Watkins spent 170 days in space as part of Expeditions 67 and 68 aboard the International Space Station. via NASA https://ift.tt/1hDN8XE
