Explanation: Pictured above is the first image ever taken of the Earth from the Moon. The image was taken in 1966 by Lunar Orbiter 1 and heralded by then-journalists as the Image of the Century. It was taken about two years before the Apollo 8 crew snapped its more famous color cousin. Recently, modern technology has allowed the recovery of higher resolution images from old data sources such as Lunar Orbiter tapes than ever before. Specifically, recovery of the above image was initiated 20 years ago by Nancy Evans, and completed recently by Dennis Wingo and Keith Cowing who lead the Lunar Orbiter Image Recovery Project. Images like that above carry more than aesthetic value — comparison to recent high definition images of the Moon enables investigations into how the Moon has been changing.

Explanation: Fomalhaut (sounds like “foam-a-lot”) is a bright, young, star, a short 25 light-years from planet Earth in the direction of the constellation Piscis Austrinus. In this sharp composite from the Hubble Space Telescope, Fomalhaut’s surrounding ring of dusty debris is imaged in detail, with overwhelming glare from the star masked by an occulting disk in the camera’s coronagraph. Astronomers now identify, the tiny point of light in the small box at the right as a planet about 3 times the mass of Jupiter orbiting 10.7 billion miles from the star (almost 14 times the Sun-Jupiter distance). Designated Fomalhaut b, the massive planet probably shapes and maintains the ring’s relatively sharp inner edge, while the ring itself is likely a larger, younger analog of our own Kuiper Belt – the solar system’s outer reservoir of icy bodies. The Hubble data represent the first visible-light image of a planet circling another star. .

Explanation: On October 7, the early dawn over northern Sudan revealed this twisted, high altitude trail. Captured in a video frame, the long-lasting persistent train is from the impact of a small asteroid cataloged as 2008 TC3. That event was remarkable because it was the first time an asteroid was detected in space before crashing into planet Earth’s atmosphere. In fact, after astronomers discovered 2008 TC3, the time and location of its impact were predicted based on follow-up observations. Later, the impact predictions were confirmed by sensors, including a Meteosat-8 image of a bright flash in the atmosphere. Astronomers are now hoping for more reports of local ground-based observations of what must have been a brilliant meteor streaking through Sudan’s night sky. Additional reports could improve the chances of recovering meteorites.

The Double Ring Galaxies of Arp 147 from Hubble

Explanation: How could a galaxy become shaped like a ring? Even more strange: how could two? The rim of the blue galaxy pictured on the right shows an immense ring-like structure 30,000 light years in diameter composed of newly formed, extremely bright, massive stars. This blue galaxy is part of the interacting galaxy system known as Arp 147, and shows a ring because it has recently collided with the other galaxy in the frame, the red galaxy on the left. Unusually, even this red galaxy shows a ring like band, although it is seen nearly edge-on. When galaxies collide, they pass through each other — their individual stars rarely come into contact. Clouds of interstellar gas and dust become condensed, causing a wave of star formation to move out from the impact point like a ripple across the surface of a pond. The above image was taken last week by NASA’s Hubble Space Telescope to demonstrate the ability of its Wide Field Planetary Camera 2 after some recent technical difficulties.

Eta Carinae, a hypergiant luminous blue variable star in the Carina constellation and one of the most massive and most luminous stars yet discovered, and the bipolar Homunculus Nebula which surrounds it. The nebula was partly created in an eruption of Eta Carinae, whose light reached Earth in 1843. Eta Carinae itself appears as the white patch near the center of the image, where the 2 lobes of the Homunculus touch.

A Spectre in the Eastern Veil

Explanation: Menacing flying forms and garish colors are a mark of the Halloween season. They also stand out in this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape covering nearly 3 degrees on the sky in the constellation Cygnus, this portion of the eastern Veil spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil’s estimated distance of 1,400 light-years from planet Earth. In this composite of image data recorded through narrow band filters, emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen atoms in greenish hues. In the western part of the Veil lies another seasonal apparition, the Witch’s Broom.
It looks like 3D w/out the glasses.

Haunting the Cepheus Flare

Explanation: Spooky shapes seem to haunt this starry expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds faintly visible in dimly reflected starlight. Far from your own neighborhood on planet Earth, they lurk at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over 2 light-years across and brighter than the other ghostly apparitions, the nebula known as Sh2-136 near the center of the field is even seen in infrared light. Also cataloged as Bok globule CB230, the core of that cloud is collapsing and is likely a binary star system in the early stages of formation.

Amazing Comet Holmes

Explanation: One year ago, Comet 17P/Holmes amazed sky watchers across planet Earth. A stunningly rapid outburst transformed it from a faint comet quietly orbiting the Sun with a period of about 7 years to a naked-eye comet rivaling the brighter stars in the constellation Perseus. Its largely tail-less shape, as in this wide-angle view recorded on November 11, 2007, became well-known to astronomers trying to unravel the mystery of the comet’s surprising outburst . Still, Comet Holmes had a dim ion tail that was seen to separate from the bright coma. In this image, the separated tail creates the illusion of a reflection nebula. It appears as a faint bluish haze right of center against a background of stars in the loosely grouped Alpha Persei Moving Cluster.

SOHO’s Uninterrupted View of the Sun

Explanation: Launched ten years ago this week, SOHO (the SOlar and Heliospheric Observatory) still enjoys an uninterrupted view of the Sun. Twelve sungazing instruments on board the spacecraft have explored the Sun’s internal structure, the extensive solar atmosphere and solar wind, and discovered over 1,000 comets from a remarkable orbit around a point about 1.5 million kilometers directly sunward of planet Earth itself. At that location, known as a Lagrange point, the gravitational influence of the Earth and Sun are equal. With scientific instrument teams distributed around the world, the SOHO operations center is located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Mission operations are planned through March of 2007 to allow the study of a complete 11-year solar cycle. Contributions from SOHO’s instruments are represented in the colorful montage image. Happy tenth anniversary SOHO!

Explanation: The Great Nebula in Orion, also known as M42, is one of the most famous nebulae in the sky. The star forming region’s glowing gas clouds and hot young stars are on the right in this sharp and colorful two frame mosaic that includes the smaller nebula M43 near center and dusty, bluish reflection nebulae NGC 1977 and friends on the left. Located at the edge of an otherwise invisible giant molecular cloud complex, these eye-catching nebulae represent only a small fraction of this galactic neighborhood’s wealth of interstellar material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems. The gorgeous skyscape spans nearly two degrees or about 45 light-years at the Orion Nebula’s estimated distance of 1,500 light-years.

Bright Bolide

Explanation: On September 30, a spectacular bolide or fireball meteor surprised a group of amateur astronomers enjoying dark night skies over the Oklahoma panhandle’s Black Mesa State Park in the Midwestern US. Flashing past familiar constellations Taurus (top) and Orion, the extremely bright meteor was captured by a hillside camera overlooking the 2008 Okie-Tex Star Party. Astronomy enthusiast Howard Edin reports that he was looking in the opposite direction at the time, but saw the whole observing field light up and at first thought someone had turned on their car headlights. So far the sighting of a such a bright bolide meteor, produced as a space rock is vaporized hurtling through Earth’s atmosphere, really is a matter of luck. But that could change. Earlier this week the discovery and follow-up tracking of tiny asteroid 2008 TC3 allowed astronomers to predict the time and location of its impact with the atmosphere. While no ground-based sightings of the fireball seem to have been reported, this first ever impact prediction was confirmed by at least some detections of an air burst and bright flash on October 7th over northern Sudan.
