ESO Top 100 Images – 100-96

June 5, 2011

by tte-77

Following some discussion last night with the team we realised how we could create a simple series of posts that could last for some weeks.  Uninstructive in their content the posts would be images from the ESO Top 100 captioned and linking to descriptions from the official archives. The course – a  dosage of 5 images a week for 20 weeks – countdown style!

The ESO Top 100 Images series gives visitors a selection of the best astronomical images taken by a suite of the world’s most advanced ground-based astronomical telescopes from the Atacama Desert in Chile.

Astonishing views of distant galaxies and nebulae, amazing night-sky landscapes, first-class telescopes with lasers shooting into the sky – the series will act as an exciting window to the Universe.

Here’s the first 5 -  images 100 counting down to image 96*.

Double take… oh, it’s NGC 6744

Astronomers say that this faraway galaxy – NGC 6744 – is a twin to our own Milky Way galaxy.

The image shown is said to be the best image yet of NGC 6744, released recently by astronomers at the European Southern Observatory (ESO) in Chile.

Astronomers took images of NGC 6744 with the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory, Chile. The images have been created by using the exposures taken through four different filters that passed blue, yellow-green and red light and the glow coming from hydrogen gas.

Similar to the Milky Way, NGC 6744 has satellite galaxies too. You can see one of them — NGC 6744A – as a smudge to the lower right of NGC 6744.

NGC 6744 is located around 30 million light-years away in the direction of the constellation of Pavo, The Peacock, which is a southern hemisphere constellation.

Astronomers say that one difference between NGC 6744 and the Milky Way is their size. While our galaxy is roughly 100,000 light-years across – NGC 6744 is twice as big. It extends to almost 200,000 light-years! While it is almost twice as large, NGC 6744 exhibits the same sharply defined spiral arms and stretched central region as the Milky Way.

Inspirational amateur photography

I was doing my regular catch-up on astronomy related photography today and cannot believe I missed this National Geographic Photo of the Day from 19 April this year. I showed the amazing photograph (above) to my partner who it turns out had already seen it (!?). Sitting down at my desk wondering if she should be posting to this blog instead an instant message popped up on my computer screen. The message pointed me here -  to a collection of simply breathtaking photographs taken by the same amateur photographer, Bret Webster from Utah, USA.

The photographs show the Milky Way in all its awe-inspiring glory.

Created by this up-and-coming photographer, they are all the more remarkable because he has been taking photographs for only three years!

Using the night skies of the national parks in his home state of Utah as the canvas, Bret Webster has created stunning photographs that really highlight the insignificance of Earth in the cosmos.

The photograph (above) – called Balanced – appeared in National Geographic magazine of April this year and though his shots of our galaxy look more like something captured by sophisticated equipment they were taken using a simple digital camera and a tripod!

Working with a Canon 5D MK2 on a tripod pointed at the sky and using a 30-60 second exposure, the photographs rely heavily on the quality of the camera equipment.

As equipment has become so advanced it is clearly possible to take such shots from the surface of the planet and use the camera sensors to capture thousands of stars at a time!

Heres a couple more to share for good measure.

Best Night-Sky Pictures of 2011

The first prize in the Beauty of the Night Sky category - Stephane Vetter, “A Starry Night of Iceland”

If this doesn’t inspire you to get your camera out then not much will! These scenes of the night sky, as seen from Earth look almost too surreal to be true.

The images below, remarkable for their beauty and captured by photographers have been named in the top ten of most vibrant and stunning photos taken across the world in the last year.

The competition, Best Night-Sky Pictures 2011 (our favourite winner above) is organised by The World At Night (TWAN) and highlights just how incredible our planet is once the sun goes down. Open to anyone, anywhere around the world the competition received around 240 entries from about 30 countries.

The image theme given this year was “Dark Skies Importance” and the submitted photos were judged in two ways: “Beauty of the Night Sky” and “Against the Lights.” The best images were those most effective in impressing people on both how important and amazing the night sky is, and also how bad light pollution has become. Today, most city skies have become virtually void of stars. Light pollution obscures the stars, interferes with astronomical observatories and of course disrupts ecosystems and has health effects.

TWANS’ criteria included a request for ‘landscape astrophotography’, or pictures of landmarks against the night sky. Their aim was to bridge the gap between the natural and man-made worlds. Here’s some to be getting on with.

Stunning.
