Space images and pictures.

Post by Smivs » Thu Jul 04, 2013 10:11 pm

Every now and again one of us finds a great space image and posts it, sometimes here, sometimes there, then we move on and it gets lost or forgotten.
So this thread is intended as somewhere to post these. The snappy title should make it easy to find in 'search', and being all in one place they could become a nice archive we can all enjoy.

So to start us off, NGC-3603 on space.com today.

100,000 stars in a sphere 100 ly in diameter - the night sky as seen from a planet within that lot would be awesome!

Comet ISON (getting closer), some stars (much further away)... and galaxies like grains of sand!

Well, since Cassini has taken our picture two days ago, here is the one from 2006. I tried to make it smaller but then we would have disappeared altogether.

Ah, one of my all-time favourites, is that. Truly beautiful - it was my desktop background for a long time...

In case anybody missed it, the Cassini image of Earth (arrowed)

This image is on the Sky News site which also contains an enlargement of the Earth in which the Moon is also visible.

Seeing those images of us, all of us, Carl Sagan's words about the Pale Blue Dot spring to mind.
From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.

Cool! Where can I find a bigger version of this picture? :)

Edit: I found it: http://apod.nasa.gov/apod/image/0901/ne ... ni_big.jpg

There appears to be a remake of Carl Sagan's Cosmos series in the works
http://www.youtube.com/watch?v=gMJxjYRX ... 8FOVvIsdsC
I'm sort of working my way through the original dvd box set of the original series not having seen it when it first came out, and i must admit i'm finding some of the (really lengthy) historical recreations stuff a chore to get through, so if they replace that stuff with faster paced animated versions this may be more my cup of tea, i know i know falling attention spans etc :lol:

Astro Picture of the Day - 28th July 2013 - Hoag's Object: A Strange Ring Galaxy
Is this one galaxy or two? This question came to light in 1950 when astronomer Art Hoag chanced upon this unusual extragalactic object. On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark. How Hoag's Object formed remains unknown, although similar objects have now been identified and collectively labeled as a form of ring galaxy. Genesis hypotheses include a galaxy collision billions of years ago and the gravitational effect of a central bar that has since vanished. The above photo taken by the Hubble Space Telescope in July 2001 revealed unprecedented details of Hoag's Object. More recent observations in radio waves indicate that Hoag's Object has not accreted a smaller galaxy in the past billion years. Hoag's Object spans about 100,000 light years and lies about 600 million light years away toward the constellation of the Snake (Serpens). Coincidentally, visible in the gap (at about one o'clock) is yet another ring galaxy that likely lies far in the distance.

Here's a photo that was being taken of the Milky Way, which also caught a surprise fireball meteor streaking across the sky.

The picture is copyright Christopher Georgia. Click on the image to take you to Space.com's page which includes the full size image.
Sometimes the best is saved for last. It certainly was the case for one night sky photographer, who was about to pack up from a night of taking time lapse images of the Milky Way when a bright meteor shot across the sky, as seen in this spectacular photo.

"I had been running a 50mm time lapse of the Milky Way passing behind Cannon Mountain Observatory for just about two hours on Friday night. Many meteors were lighting up the sky throughout the night," photographer Christopher Georgia wrote SPACE.com in an email.

"Just as I was about to break down my equipment and head out, one of the brightest fireballs I had seen all night lit up the sky just to the left of the Milky Way."

Georgia took this shot in July near Cannon Mountain Observatory in Franconia, New Hampshire. He used a Nikon D3s camera, Nikon 50mm lens, exposure 10 seconds, f/2.8 and ISO 2500, to capture the image. The photo was release to SPACE.com July 17, 2013.

Not exactly an image as such, but there is an interesting article here on the Bad Astronomy blog which includes an animation of how the Crab Nebular has expanded over a thirteen year period.
