A Partial Eclipse of an Active Sun

Copyright: Watch for three things in this unusual eclipse video. First, watch for a big dark circle to approach from the right to block out more and more of the Sun. This dark circle is the Moon, and the video was made primarily to capture this partial solar eclipse last week. Next, watch a large […]

NGC 6357: The Lobster Nebula

NGC 6357: The Lobster Nebula

Copyright: Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center — a home to unusually bright and massive stars. The overall red glow near the inner star forming region […]

LDN 43: The Cosmic Bat Nebula

LDN 43: The Cosmic Bat Nebula

Copyright: Mark HansonMike SelbyMichelle ThallerNASAGSFC What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying 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 […]

Night on a Spooky Planet

Night on a Spooky Planet

Copyright: Stéphane VetterNuits sacrées What spooky planet is this? Planet Earth of course, on a dark and stormy night in 2013 at Hverir, a geothermally active area along the volcanic landscape in northeastern Iceland. Triggered by solar activity, geomagnetic storms produced the auroral display in the starry night sky. The ghostly towers of steam and […]

LDN 673: Dark Clouds in Aquila

LDN 673: Dark Clouds in Aquila

Copyright: Capella Observatory Team Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through planet Earth’s skies near bright star Altair. In eerie silhouette against the Milky Way’s faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars […]

Seven Years of Halley Dust

Seven Years of Halley Dust

Copyright: Petr Horalek History’s first known periodic comet Halley (1P/Halley) returns to the inner Solar System every 75 years or so. The famous comet made its last appearance to the naked-eye in 1986. But dusty debris from Comet Halley can be seen raining through planet Earth’s skies twice a year during two annual meteor showers, […]

Sunset, Moonset, Taj Mahal

Sunset, Moonset, Taj Mahal

Copyright: Neelam and Ajay Talwar On October 25th, Sun and New Moon set together as seen from Agra, India. Their close conjunction near the western horizon, a partial solar eclipse, was captured in this elevated view in hazy skies near the solitary dome of the Taj Mahal. Of course, the partial solar eclipse was also […]

Cocoon Nebula Wide Field

Cocoon Nebula Wide Field

Copyright: Andy Ermolli When does a nebula look like a comet? In this crowded starfield, covering over two degrees within the high flying constellation of the Swan (Cygnus), the eye is drawn to the Cocoon Nebula. A compact star forming region, the cosmic Cocoon punctuates a nebula bright in emission and reflection on the left, […]

Jupiter Rotates as Moons Orbit

Copyright: Makrem Larnaout Jupiter and its moons move like our Sun and its planets. Similarly, Jupiter spins while its moons circle around. Jupiter’s rotation can be observed by tracking circulating dark belts and light zones. The Great Red Spot, the largest storm known, rotates to become visible after about 15 seconds in the 48-second time […]

Clouds Around Galaxy Andromeda

Clouds Around Galaxy Andromeda

Copyright: Andrew Fryhover What are those red clouds surrounding the Andromeda galaxy? This galaxy, M31, is often imaged by planet Earth-based astronomers. As the nearest large spiral galaxy, it is a familiar sight with dark dust lanes, bright yellowish core, and spiral arms traced by clouds of bright blue stars. A mosaic of well-exposed broad […]

Milky Way and Zodiacal Light over Australian Pinnacles

Milky Way and Zodiacal Light over Australian Pinnacles

Copyright: Jingyi Zhang What strange world is this? Earth. In the foreground of the featured image are the Pinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sized picturesque spires formed remains a topic of research. The picturesque panorama was taken in 2017 September. A […]

NGC 1499: The California Nebula

Copyright: this cosmic cloud Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way’s Orion Arm, only about 1,500 light-years from the California Nebula. Also known as […]

Andromeda in Southern Skies

Andromeda in Southern Skies

Copyright: Ian Griffin Looking north from southern New Zealand, the Andromeda Galaxy never gets more than about five degrees above the horizon. As spring comes to the southern hemisphere, in late September Andromeda is highest in the sky around midnight though. In a single 30 second exposure this telephoto image tracked the stars to capture […]

Pillars of Creation

Pillars of Creation

Copyright: A now famous picture from the Hubble Space Telescope featured these star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula, dubbed the Pillars of Creation. This James Webb Space Telescope NIRCam image expands Hubble’s exploration of that region in greater detail and depth inside the iconic stellar nursery. […]

A Galaxy Beyond Stars, Gas, Dust

A Galaxy Beyond Stars, Gas, Dust

Copyright: Howard TrottierEmily Rice Do we dare believe our eyes? When we look at images of space, we often wonder whether they are “real”, and just as often the best answer varies. In this case, the scene appears much as our eyes would see it, because it was obtained using RGB (Red, Green, Blue) filters […]
