Video: Flash on Jupiter

Copyright: T. Humbert, S. Barré, A. Desmougin & D. WalliangSociété Lorraine d’AstronomieAstroqueyras There has been a flash on Jupiter. A few days ago, several groups monitoring our Solar System’s largest planet noticed a two-second long burst of light. Such flashes have been seen before, with the most famous being a series of impactor strikes in […]

Cyclone Paths on Planet Earth

Copyright: Where on Earth do cyclones go? Known as hurricanes when in the Atlantic Ocean and typhoons when in the Pacific, the featured map shows the path of all major storms from 1985 through 2005. The map shows graphically that cyclones usually occur over water, which makes sense since evaporating warm water gives them energy. […]

Mars Panorama 360 from Curiosity

Copyright: Which way up Mount Sharp? In early September, the robotic rover Curiosity continued its ascent up the central peak of Gale Crater, searching for more clues about ancient water and further evidence that Mars could once have been capable of supporting life. On this recent Martian morning, before exploratory drilling, the rolling rover took […]

Night Sky Reflected

Copyright: Egon Filter What’s that in the mirror? In the featured image of the dark southern sky, the three brightest galaxies of the night are all relatively easy to identify. Starting from the left, these are the Small Magellanic Cloud (SMC), the Large Magellanic Cloud (LMC), and part of the central band of our Milky […]

A Spiral Aurora over Iceland

Copyright: Davide Necchi What’s happened to the sky? Aurora! Captured in 2015, this aurora was noted by Icelanders for its great brightness and quick development. The aurora resulted from a solar storm, with high energy particles bursting out from the Sun and through a crack in Earth’s protective magnetosphere a few days later. Although a […]

Rosetta’s Comet in View

Copyright: CARA Project Faint comet Churyumov-Gerasimenko (67P) sweeps past background stars in the constellation Taurus and even fainter distant galaxies in this telescopic frame from September 7. About 5 years ago, this comet’s 4 kilometer spanning, double-lobed nucleus became the final resting place of robots from planet Earth, following the completion of the historic Rosetta […]

M16 Cose Up

Copyright: Martin Pugh A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region adopts the colorful Hubble palette and includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. […]

The Deep Sky Toward Andromeda

Copyright: What surrounds the Andromeda galaxy? Out in space, Andromeda (M31) is closely surrounded by several small satellite galaxies, and further out it is part of the Local Group of Galaxies — of which our Milky Way galaxy is also a member. On the sky, however, gas clouds local to our Milky Way appear to […]

NGC 520: Colliding Galaxies from Hubble

Copyright: Is this one galaxy or two? The jumble of stars, gas, and dust that is NGC 520 is now thought to incorporate the remains of two separate disk galaxies. A defining component of NGC 520 — as seen in great detail in the featured image from the Hubble Space Telescope — is its band […]

Firefly Milky Way over Russia

Copyright: Anton Komlev It started with a pine tree. The idea was to photograph a statuesque pine in front of the central band of our Milky Way Galaxy. And the plan, carried out two months ago, was successful — they both appear prominently. But the resulting 3-frame panorama captured much more. Colorful stars, for example, […]

Earth and Moon

Copyright: The Earth and Moon are rarely photographed together. One of most spectacular times this occurred was about 30 years ago when the Jupiter-bound Galileo spacecraft zoomed past our home planetary system. Then, robotic Galileo watched from about 15-times the Earth-Moon separation as our only natural satellite glided past our home world. The featured video […]

A Falcon 9 Nebula

Copyright: Dennis Huff Not the Hubble Space Telescope’s latest view of a distant galactic nebula, this illuminated cloud of gas and dust dazzled early morning spacecoast skygazers on August 29. The snapshot was taken at 3:17am from Space View Park in Titusville, Florida. That’s about 3 minutes after the launch of a SpaceX Falcon 9 […]

Dancing Ghosts: Curved Jets from Active Galaxies

Copyright: Why would galaxies emit jets that look like ghosts? And furthermore, why do they appear to be dancing? The curled and fluffy jets from the supermassive black holes at the centers of two host galaxies (top center and lower left) are unlike anything seen before. They were found by astronomers using the Australian Square […]

A Blue Moon in Exaggerated Colors

Copyright: Robert Fedez The Moon is normally seen in subtle shades of grey or gold. But small, measurable color differences have been greatly exaggerated to make this telescopic, multicolored, moonscape captured during the Moon’s full phase. The different colors are recognized to correspond to real differences in the chemical makeup of the lunar surface. Blue […]

A Fire Rainbow over West Virginia

Copyright: What’s happening to this cloud? Ice crystals in a distant cirrus cloud are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a […]
