I don’t usually post today’s APOD — I usually wait a few days — but, well, today’s APOD photo is nothing short of spectacular. Since this is yet another section of the vast and wonderful Veil Nebula, I’m not surprised it caught my eye! To put it in geek speak, that whole region of the sky is made of WIN.

Explanation: Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. Pictured above is the west end of the Veil Nebula known technically as NGC 6960 but less formally as the Witch’s Broom Nebula. The expanding debris cloud gains its colors by sweeping up and exciting existing nearby gas. The supernova remnant lies about 1400 light-years away towards the constellation of Cygnus. This Witch’s Broom actually spans over three times the angular size of the full Moon. The bright star 52 Cygni is visible with the unaided eye from a dark location but unrelated to the ancient supernova.

Today’s Picture of the Day @ NASA is the Peony Nebula, and this dreamily-colored image is downloadable in standard desktop/wallpaper sizes.

If our galaxy were to host its own version of the Olympics, the title for the brightest known star would go to a massive star called Eta Carina. However, a new runner-up, now the second-brightest star in our galaxy, has been discovered in the galaxy’s dusty and frenzied interior. This image from NASA’s Spitzer Space Telescope shows the new silver medalist, circled in the inset above, in the central region of our Milky Way.

Dubbed the Peony nebula star, this blazing ball of gas shines with the equivalent light of 3.2 million suns. The reigning champ, Eta Carina, produces the equivalent of 4.7 million suns worth of light. However, astronomers say these estimates are uncertain, and it’s possible that the Peony nebula star could be even brighter than Eta Carina.

If the Peony star is so bright, why doesn’t it stand out more in this view? The answer is dust. This star is located in a very dusty region jam packed with stars. In fact, there could be other super bright stars still hidden deep in the stellar crowd. Spitzer’s infrared eyes allowed it to pierce the dust and assess the Peony nebula star’s true brightness. Likewise, infrared data from the European Southern Observatory’s New Technology Telescope in Chile were integral in calculating the Peony nebula star’s luminosity.

NASA Images is a great new(er) resource developed last year as a joint project between NASA and Archive.org. If you’ve been looking for a one-stop resource for everything NASA does, you just found it!

NASA Images is a service of Internet Archive ( www.archive.org ), a non-profit library, to offer public access to NASA’s images, videos and audio collections. NASA Images is constantly growing with the addition of current media from NASA as well as newly digitized media from the archives of the NASA Centers.

The goal of NASA Images is to increase our understanding of the earth, our solar system and the universe beyond in order to benefit humanity.

For this week’s Perspective, I chose something that is indeed from a different perspective… literally! The above image was taken from the International Space Station during STS-123:

STS123-E-008018 (21 March 2008) — While docked and onboard the International Space Station, a STS-123 Endeavour crewmember captured the glowing green beauty of the Aurora Borealis. Looking northward across the Gulf of Alaska, over a low pressure area (cloud vortex), the aurora brightens the night sky.

The Kennedy Media Gallery is my one-stop source for launch and landing photos of the Space Shuttle missions. Sure, the NASA Human Spaceflight site gives you some of them… but not ALL, not like this! The above is just one example (from the STS-123 night landing, earlier this year) of the gobs and gobs of photos awaiting your downloading pleasure. Got broadband?

Released last week, the Apollo Surface Panoramas archive gives public access to some remarkable photographic panoramas taken on the lunar surface.

Apollo Surface Panoramas is a digital library of photographic panoramas that the Apollo astronauts took while exploring the Moon’s surface. These images provide a spectacular boots-on-the-ground view of the lunar landscape. The panoramas are stitched together from individual 70mm Hasselblad frames, each of which is also accessible through this new atlas. Lunar surface features captured in the panoramas can be studied using zoom and pan tools. An annotated version of each panorama is also available to assist users with the identification of major geographic features around each Apollo landing site.
