Herbig-Haro 24

This might look like a double-bladed lightsaber, but these two cosmic jets actually beam outward from a newborn star in a galaxy near you. Constructed from Hubble Space Telescope image data, the stunning scene spans about half a light-year across Herbig-Haro 24 (HH 24), some 1,300 light-years or 400 parsecs away in the stellar nurseries […]

Zeta and Rho Ophiuchi with Milky Way

Copyright: Ireneusz Nowak Behold one of the most photogenic regions of the night sky, captured impressively. Featured, the band of our Milky Way Galaxy runs diagonally along the bottom-left corner, while the colorful Rho Ophiuchi cloud complex is visible just right of center and the large red circular Zeta Ophiuchi Nebula appears near the top. […]

Spiral Galaxy NGC 2566 from Webb

What’s happening in the center of spiral galaxy NGC 2566? First, the eight rays that appear to be coming out of the center in the featured infrared image are not real — they are diffraction spikes caused by the mechanical structure of the Webb space telescope itself. The center of NGC 2566 is bright but […]

Beneath Jupiter

Copyright: NASA, Juno, SwRI, MSSS; Processing & License: Gerald Eichstädt & Seán Doran Jupiter is stranger than we knew. NASA’s Juno spacecraft has now completed over 70 swoops past Jupiter as it moves around its highly elliptical orbit. Pictured from 2017, Jupiter is seen from below where, surprisingly, the horizontal bands that cover most of […]

Deimos Before Sunrise

Deimos takes 30 hours and 18 minutes to complete one orbit around the Red Planet. That’s a little more than one Martian day or sol which is about 24 hours and 40 minutes long, so Deimos drifts westward across the Martian sky. About 15 kilometers across at its widest, the smallest of Mars’ two moons […]

NGC 6366 vs 47 Ophiuchi

Copyright: Massimo Di Fusco Most globular star clusters roam the halo of our Milky Way galaxy, but globular cluster NGC 6366 lies close to the galactic plane. About 12,000 light-years away toward the constellation Ophiuchus, the cluster’s starlight is dimmed and reddened by the Milky Way’s interstellar dust when viewed from planet Earth. As a […]

Curly Spiral Galaxy M63

Copyright: Alberto Pisabarro A bright spiral galaxy of the northern sky, Messier 63 is nearby, about 30 million light-years distant toward the loyal constellation Canes Venatici. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across, about the size of our own Milky Way. Its bright core and majestic spiral arms […]

International Space Station Crosses the Sun

Copyright: Pau Montplet Sanz Typically, the International Space Station is visible only at night. Slowly drifting across the night sky as it orbits the Earth, the International Space Station (ISS) can be seen as a bright spot about once a month from many locations. The ISS is then visible only just after sunset or just […]

Milky Way over Maunakea

Copyright: Marzena Rogozinska Have you ever seen the band of our Milky Way Galaxy? In a clear sky from a dark location at the right time, a faint band of light becomes visible across the sky. Soon after your eyes become dark adapted, you might spot the band for the first time. It may then […]

Charon Flyover from New Horizons

What if you could fly over Pluto’s moon Charon — what might you see? The New Horizons spacecraft did just this in 2015 July as it zipped past Pluto and Charon with cameras blazing. The images recorded allowed for a digital reconstruction of much of Charon’s surface, further enabling the creation of fictitious flights over […]

Pluto Flyover from New Horizons

What if you could fly over Pluto — what might you see? The New Horizons spacecraft did just this in 2015 July as it shot past the distant world at a speed of about 80,000 kilometers per hour. Images from this spectacular passage have been color enhanced, vertically scaled, and digitally combined into the featured […]

Ares 3 Landing Site: The Martian Revisited

This close-up from the Mars Reconnaissance Orbiter’s HiRISE camera shows weathered craters and windblown deposits in southern Acidalia Planitia. A striking shade of blue in standard HiRISE image colors, to the human eye the area would probably look grey or a little reddish. But human eyes have not gazed across this terrain, unless you count […]

Messier 101

Big, beautiful spiral galaxy M101 is one of the last entries in Charles Messier’s famous catalog, but definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way. M101 was also one of the original spiral nebulae observed by Lord Rosse’s large 19th […]

A Plutonian Landscape

Copyright: This shadowy landscape of majestic mountains and icy plains stretches toward the horizon on a small, distant world. It was captured from a range of about 18,000 kilometers when New Horizons looked back toward Pluto, 15 minutes after the spacecraft’s closest approach on July 14, 2015. The dramatic, low-angle, near-twilight scene follows rugged mountains […]

NGC 1360: The Robin’s Egg Nebula

Copyright: Andrea Iorio, Vikas Chander & ShaRA Team This pretty nebula lies some 1,500 light-years away, its shape and color in this telescopic view reminiscent of a robin’s egg. The cosmic cloud spans about 3 light-years, nestled securely within the boundaries of the southern constellation of the Furnace (Fornax). Recognized as a planetary nebula, egg-shaped […]
