Sky-Watching Images of the Year 2011

December 31, 2011

by yaska77

You might not have noticed but we love posting astro related imagery here at Sky-Watching. With that in mind we decided to put together our favourite images from throughout the year, as voted for by us :)

Sky-Watching Image of the Year 2011

At the risk of sounding like blowing our own trumpet, chosen independently as their favourite blog image from 2011 by both tte-77 and mattelk (with no coercion from me whatsoever!) this was one of the first ever stacked images I captured and processed.

Galaxies are fascinating for their variety and magnitude, so to photograph one so clearly using our own equipment through our own light polluted skies helped my M31 Andromeda image stand out.

Creating images like this was one of the main reasons I bought a telescope and camera in the first place, so astrophotography can be very rewarding when your efforts pay off.

The original post (also featuring the Orion Nebula and The Pleiades) can be viewed here.

Sky-Watching Best Planetary Image 2011

As soon as mattelk first posted this image of Saturn from the Cassini spacecraft we knew it would be a contender for the best planetary image of the year.

Taken by Cassini as it drifted in the shadow of the planet Saturn (looking towards the eclipsed sun) the night side of the planet is illuminated by sunlight reflected from its own ring system, and the rings themselves are lit by sunlight scattering off of the particles in the ring system.

The small white dot just top left of the main ring system is us, planet Earth!

Jaw-dropping.

Sky-Watching Historic Images of 2011

We followed the last months of NASA’s space shuttle program incredibly closely, so as 2011 saw the end of the iconic spacecraft (with all 3 remaining orbiters retired to museums) it’s only right that we picked a couple of historic shuttle photos for images of particular historic interest.

The image captured above by Paolo Nespoli from a Soyuz capsule returning to Earth were historic, as the first ever images taken from space of a shuttle docked to the ISS. Nothing like waiting for the penultimate mission!

NASA officials said this spacecraft “family portrait” served as a reminder of the contributions the shuttle program made to the construction of the International Space Station.  The 100 billion dollar station began assembly in 1998 with the Russian module Zarya, and then a certain orbiter called Endeavour (STS-88) took the first US built section (the Unity Module) into orbit the same year.

The NASA gallery page features several more photographs, take a look here.

NASA’s space shuttle Atlantis (STS-135) blasted into orbit on 8th July 2011 on the 135th and final space shuttle mission, launching from Kennedy Space Center (on a 13 day mission delivering supplies to the ISS) with thousands of spectators lining the roads and beaches nearby.

With the shuttle flying no more, we’re eagerly awaiting NASA’s next innovation in launch systems.

It’s been a good year for great images, and we’re now eagerly waiting to see what 2012 will bring.

Different images evoke different responses in different people, but we managed to agree what images should feature, even if I abstained from voting for one of them (for obvious reasons of favouritism) ;)

And on that note all of us at Sky-Watching wish all our visitors, subscribers and Twitter followers a very Happy New Year, may 2012 be great for all of you.

So let’s finish 2011 with a smile, this little image posted through Twitter made me laugh, and from comments made it caused a few chuckles in others too!

Just for Fun

A good year to watch the Draconid meteor shower

October 6, 2011

by tte-77

Taken from yaska77′s Astronomy Events – October 2011 post.

Saturday 8th OctoberThe annual Draconid meteor shower (also known as the Giacobinids) should reach its peak this evening (the height of activity expected between 16:00 and 22:00 UTC/GMT), with calculations suggesting we could be in for an outstanding display. The ZHR (Zenithal Hourly Rate) could range from a few tens of meteors per hour to several hundred

Here is a little extra on the Draconid meteor shower to help with locating Draco the Dragon, the Dragon’s eyes and the showers radiant point.

The Draconid meteor shower generally favours northerly latitudes. The best viewing of the meteors will mostly be at early to mid evening on Saturday 8th October – this is when the radiant point for the shower located in the constellation Draco the Dragon will be highest in the sky for that night. The most meteors tend to fall when radiant point is highest in the sky.

Although it is not essential to identify the meteor shower radiant to watch the Draconids as they streak all over the sky, doing so does allow you to trace the paths of the meteors backward – you will notice how they appear to radiate from the Dragon’s head!

See the image below to locate the Dragon’s eyes. Locate the two brightest stars in the constellation (Eltanin and Rastaban) to see the radiant point of the Draconid meteor shower.

The radiant will fall downward during the night reaching its lowest point around dawn, as seen from all points in the northern hemisphere.

So from early to mid evening on Saturday will probably provide the greatest number of meteors with the 2011 shower possibly producing a meteor storm of several hundred meteors per hour at its peak! The best locations are said to be Europe, North Africa and the Middle East. The one downside is that in the south there will be a bright moon with its light possibly affecting the view of the shower.

Get outside if you get a chance and go view!

Eclipse season for the Solar Dynamics Observatory

Earth eclipse of the sun

The beginning of the eclipse season begins from the vantage point in space of NASA’s Solar Dynamics Observatory (SDO) – this recent image shows an Earth eclipse of the sun.

For three weeks near to 0700 UTC our orbit has the Earth pass between NASA’s SDO and the Sun. The eclipses can for around an hour in the middle of an eclipse season. The current eclipse season started on 11 September and lasts until 4 October.

Stationed in geosynchronous orbit about 22,000 miles above Earth the eclipse season for NASA’s SDO begins twice a year near each equinox, according to NASA.

Visit NASA’s Solar Dynamics Observatory here for more eclipse images in the coming weeks.

Amazing shot.

Yay yay – the Allen Telescope Array!

skywatching Allen Telescope Array SETI

Telescopes looking for extra terrestrial intelligence should re-open within weeks after donors replaced income lost in public funding cuts.

The Search for Extraterrestrial Intelligence (SETI) Institute, had to shut the £18m Allen Telescope Array in April but donors have since raised more than £120,000 with more than 2,400 people contributing to the fund. Donors include the likes of actress Jodie Foster who played the lead role of an astronomer looking for evidence of aliens in the 1997 film Contact. Amongst other donors was the Apollo 8 astronaut, Bill Anders.

The 42 radio telescopes, in northern California, search space for potential signals from alien life forms.

The SETI Institute says the fund should be enough to keep the telescopes operating until the end of 2011.  The plan is still dependent on the institute receiving money from the US Air Force to help track space debris that could damage satellites.

SETI is hoping to raise more money to contribute to the £1.5m annual operating and staffing costs of the telescopes and keep them going beyond the end of this year. Ultimately the plan is to use the array to observe planets outside our own Solar System.

The array also contributes to research into black holes, pulsars and magnetic fields in the Milky Way.
