ESO: Wild Ducks Take Flight in Open Cluster (M11)

[b][i]ESO Wide Field Imager (WFI) on the MPG/ESO 2.2-metre telescope[/i][/b]

---

The Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile has taken this beautiful image, dappled with blue stars, of one of the most star-rich open clusters currently known — Messier 11, also known as NGC 6705 or the Wild Duck Cluster.

Messier 11 is an open cluster, sometimes referred to as a galactic cluster, located around 6000 light-years away in the constellation of Scutum (The Shield). It was first discovered by German astronomer Gottfried Kirch in 1681 at the Berlin Observatory, appearing as nothing more than a fuzzy blob through the telescope. It wasn’t until 1733 that the blob was first resolved into separate stars by the Reverend William Derham in England, and Charles Messier added it to his famous catalogue in 1764. ...

The alternative and evocative name for NGC 6705, the Wild Duck Cluster, came about in the 19th century. When the cluster was seen through a small telescope it was noticed that the brightest stars formed an open triangle pattern on the sky that resembled ducks flying in formation.

Nick Risinger has always gazed up at the sky. But last year the amateur astronomer and photographer quit his day job as a Seattle marketing director and lugged six synchronized cameras about 60,000 miles to capture an image of the entire night sky.

Risinger, 28, set up his rack of cameras in high-elevation locales in the Western U.S. and South Africa, timing photo shoots around new moons when nights were long and dark. He programmed his six cameras to track the stars as they moved across the sky and simultaneously snapped thousands of photos.

He then stitched 37,440 exposures together into a spectacular, panoramic survey sky that he posted online two weeks ago. The photo reveals a 360-degree view of the Milky Way, planets and stars in their true natural colors. Viewers can zoom in on portions of the 5,000-megapixel image to find Orion or the Large Magellanic Cloud. ...

Royal Museums, Greenwich
Astronomy Photographer of the Year exhibition

Click to play embedded YouTube video.

Last month we announced the stunning winners of the 2014 Astronomy Photographer of the Year competition. These breath-taking images are now on display in a new exhibition at the Royal Observatory Greenwich, where you can see them up close and find out more about the stories behind them. If you can't make it to the exhibition you can also view the winners online , or own them with the official publication. In the video above the expert judges tell you why they loved the overall winner.

This is a Found Image, which came via a newsletter I get from Greenwich, but is a video of a still image, so I wasn't sure where to post it. If I decided wrongly, please move it.
I'm assuming the YouTube video is openly available for use, but I haven't contacted the Royal Museums to ask.

Children Building an E-ELT Mirror
ESO Picture of the Week (2014 Oct 06)

This aerial image shows a 1:1 scale model of the European Extremely Large Telescope's primary mirror, assembled next to the Asiago Astrophysical Observatory near Asiago, Italy.

The Italian observatory, founded in 1942, is dwarfed by the gargantuan E-ELT mirror… in fact, you could fit the entire Asiago building inside the footprint of the E-ELT mirror and still have enough room to swing a proverbial cat (and a big cat too)!

Around the edge of the mock-up mirror are the children who volunteered to participate in the task of positioning the 800 1.4-metre cardboard hexagons used to form the 39-metre E-ELT mirror mock-up.

A Dusty Spiral Galaxy in Virgo (NGC 4206)
ESA Hubble Picture of the Week (2014 Oct 06)

[b][i]Credit: ESA/Hubble & NASA; Acknowledgement: Nick Rose[/i][/b]

---

This magnificent new image taken with the NASA/ESA Hubble Space Telescope shows the edge-on spiral galaxy NGC 4206, located about 70 million light-years away from Earth in the constellation of Virgo.

Captured here are vast streaks of dust, some of which are obscuring the central bulge, which can just be made out in the centre of the galaxy. Towards the edges of the galaxy, the scattered clumps, which appear blue in this image, mark areas where stars are being born. The bulge, on the other hand, is composed mostly of much older, redder stars, and very little star formation takes place.

NGC 4206 was imaged as part of a Hubble snapshot survey of nearby edge-on spiral galaxies to measure the effect that the material between the stars — known as the interstellar medium — has on light as it travels through it. Using its Advanced Camera for Surveys, Hubble can reveal information about the dusty material and hydrogen gas in the cold parts of the interstellar medium. Astronomers are then able to map the absorption and scattering of light by the material — an effect known as extinction — which causes objects to appear redder to us, the observers.

NGC 4206 is visible with most moderate amateur telescopes at 13th magnitude. It was discovered by Hanoverian-born British astronomer, William Herschel on 17 April 1784. ...

That was my reaction when I first saw it but now it doesn't seem as impressive. I also wish it was wider and included more of Monoceros and Canis Major.

Description
ESA astronaut Alexander Gerst spent six hours and 13 minutes outside the International Space Station with NASA astronaut Reid Wiseman on Tuesday, 7 October 2014. This was the first spacewalk for both astronauts but they performed well in the weightlessness of orbit.
... After working with Reid to attach the pump, Alexander took the arm for a last ride to park it and prepare it for its next use, berthing visiting spacecraft. Here, Alexander had his hands free and time to take a few photographs, such as this one.

MUSE: Galactic Chromodynamics (M87)

[b][i]Credit: Eric Emsellem/ESO[/i][/b]

---

This colourful picture resembles an abstract painting, or perhaps a contemporary stained-glass window. But it is actually an unusual view of a galaxy taken with the new MUSE instrument on ESO’s Very Large Telescope.

Colours in astronomical pictures are usually related to the real colour of an object. In this image, however, the colours represent the motion of the stars that form the giant elliptical galaxy Messier 87 — one of the brightest galaxies in the Virgo Cluster which lies about 50 million light-years away.

Red in the image indicates that stars in that part of the object are, on average, moving away from us, blue means they are coming towards us, and yellow and green are in between.

This new map of Messier 87 from MUSE shows these trends more clearly than ever before. It reveals a slow rotation of this massive object — the upper left part (in blue) is coming towards us and the lower right (in red) is moving away. It also reveals some unexpected features — for example the reversal of colours at the centre of the image, with blueish in the lower part of the centre and yellow–orange in the upper part — that suggest Messier 87 may have had a more dramatic past than previously believed, and may thus be the result of the merging of several galaxies.

Turquoise-tinted plumes in the Large Magellanic Cloud

The brightly glowing plumes seen in this image are reminiscent of an underwater scene, with turquoise-tinted currents and nebulous strands reaching out into the surroundings.

However, this is no ocean. This image actually shows part of the Large Magellanic Cloud (LMC), a small nearby galaxy that orbits our galaxy, the Milky Way, and appears as a blurred blob in our skies. The NASA/ESA Hubble Space Telescope has peeked many times into this galaxy, releasing stunning images of the whirling clouds of gas and sparkling stars (opo9944a, heic1301, potw1408a).

This image shows part of the Tarantula Nebula's outskirts. This famously beautiful nebula, located within the LMC, is a frequent target for Hubble (heic1206, heic1402).

In most images of the LMC the colour is completely different to that seen here. This is because, in this new image, a different set of filters was used. The customary R filter, which selects the red light, was replaced by a filter letting through the near-infrared light. In traditional images, the hydrogen gas appears pink because it shines most brightly in the red. Here however, other less prominent emission lines dominate in the blue and green filters.

This data is part of the Archival Pure Parallel Project (APPP), a project that gathered together and processed over 1000 images taken using Hubble’s Wide Field Planetary Camera 2, obtained in parallel with other Hubble instruments. Much of the data in the project could be used to study a wide range of astronomical topics, including gravitational lensing and cosmic shear, exploring distant star-forming galaxies, supplementing observations in other wavelength ranges with optical data, and examining star populations from stellar heavyweights all the way down to solar-mass stars.

In my opinion, there are a lot better targets/regions in the LMC that they could have chosen to take an image of.

That was a parallel observation. The telescope can rotate around so that the parallel field can be anywhere in a circle around the primary observation but other than that there isn't much of a choice where the parallel field is aimed at.
