Behold: SS 433 – one of the most exotic eclipsing x-ray binary star systems we know of. And that’s saying something. To wit:

Its unremarkable name stems from its inclusion in a catalog of Milky Way stars which emit radiation characteristic of atomic hydrogen. Its remarkable behaviour stems from a compact object, a black hole or neutron star, which has produced an accretion disk with jets. Because the disk and jets from SS 433 resemble those surrounding supermassive black holes in the centres of distant galaxies, SS 433 is considered a micro-quasar. As illustrated in the animated featured video based on observational data, a massive, hot, normal star is locked in orbit with the compact object. As the video starts, material is shown being gravitationally ripped from the normal star and falling onto an accretion disk. The central star also blasts out jets of ionised gas in opposite directions – each at about 1/4 the speed of light. The video then pans out to show a top view of the precessing jets producing an expanding spiral. From even greater distances, the dissipating jets are then visualised near the heart of supernova remnant W50. Two years ago, SS 433 was unexpectedly found by the HAWC detector array in Mexico to emit unusually high energy (TeV-range) gamma-rays. Surprises continue, as a recent analysis of archival data taken by NASA‘s Fermi satellite find a gamma-ray source — separated from the central stars as shown — that pulses in gamma-rays with a period of 162 days – the same as SS 433’s jet precession period – for reasons yet unknown.

Last week, with a PAIR of free tickets to see Stars – one of the best Canadian indie bands of their generation –  perform their stunning 2004 masterpiece Set Yourself On Fire in Dublin’s Workmans Club on Friday September 27 on offer,  I asked YOU to name your favourite piece of music referencing stars.

You answered in your tens.

But there could be only one winner.

Third Place:

The Church – Under The Milky Way

Catherine Vaughan writes:

If you’re gonna reference stars, why not go all out, and reference the whole Milky Way!

Runner up:

Stars Of Heaven – Lights Of Tetouan

Brother Barnabas writes:

Yeah, I know – but no matter: that’s as good as pop gets…

Winner:

Don McLean – Starry Starry Night.

Bilbo writes:

You people are crazy, it’s Starry Starry Night. Apart from being fantastic lyrically and musically you could very easily draw a line from Don’s singing in this song directly to Torquil (of Stars) singing on Set Yourself on Fire (you’d have to make a brief stop-off at Morrissey considering the blatantly Morrissey-equee track Take Me To The Riots….on 2007’s In Our Bedroom After The War) I refuse to believe this album (Set Yourself On Fire) came out in 2004.

Thanks all.

Last week: Win Nick’s Free Tix

In the mood for exquisite chamber pop?

Then you are in luck as Stars – one of the best Canadian indie bands of their generation – return to perform their stunning 2004 masterpiece Set Yourself On Fire.

The Montreal collective led by Torquil and Amy have added a second late show at 11pm in Dublin’s Workmans Club on Friday September 27 after the earlier one sold out.

I have 2 free tickets to give to a reader to the late show.

Simply tell me below what is your favourite song referencing stars?

My astrologer Fergus will choose the winner.

Lines MUST close at 5.15pm EXTENDED until 10.15pm 3am.

Nick says: Good luck!

Behold: stars forming in Lynd’s Dark Nebula (LDN 1251). To wit:

About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, the dusty molecular cloud is part of a complex of dark nebulae mapped toward theCepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects seen in this sharp image. Distant background galaxies also lurk on the scene, visually buried behind the dusty expanse. The deep telescopic field of view imaged with broadband filters spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251.

A colourful composite of three bright nebulae in the constellation of Sagittarius –  recorded last last year from Teide National Park in Tenerife. To wit:

18th century cosmic tourist Charles Messier cataloged two of them; M8, the large nebula just left of centre, and colourful M20 on the top left. The third emission region includes NGC 6559 and can be found to the right of M8. All three are stellar nurseries about five thousand light-years or so distant. Over a hundred light-years across, the expansive M8 is also known as the Lagoon Nebula. M20’s popular moniker is the Trifid. Glowing hydrogen gas creates the dominant red colour of the emission nebulae. In striking contrast, blue hues in the Trifid are due to dust reflected starlight. Recently formed bright blue stars are visible nearby.

Behold: the bright young stars of the Trumpler 14 cluster – some as young as a mere 5 million years and still so hot, they emit detectable x-rays. Listen up, grandad:

In older star clusters, most stars this young have already died — typically exploding in a supernova — leaving behind stars that are fainter and redder. Trumpler 14 spans about 40 light years and lies about 9,000 light years away on the edge of the famous Carina Nebula. A discerning eye can spot two unusual objects in this detailed 2006 image of Trumpler 14 by the Hubble Space Telescope. First, a dark cloud just left of center may be a planetary system trying to form before being destroyed by the energetic winds ofTrumpler 14‘s massive stars. Second is the arc at the bottom left, which one hypothesis holds is the supersonic shock wave of a fast star ejected 100,000 years ago from a completely different star cluster.

A very pleasing experimental 4k CGI short by Maxim Zhestkov exploring the nature of the Universe formed by coalescing matter thrown out by exploding stars. To wit:

Everything around and inside us was conceived in a huge explosion of a star billions of years ago… and, probably, recycled from other matrices myriad times. In this eternal carousel of matter, particles gather, form complicated structures and then burst into all directions fusing atoms together and producing new elements and points of view, new colours and patterns of perception.

Some of the world’s oldest living trees ((in Botswana, Namibia and  South Africa) photographed against the backdrop of the night sky by Beth Moon, who sez:

The majority of these photographs were created during moonless nights, shot with a wide angle lens and ISO of 3200 – 6400. The Milky Way, a ribbon of stars that stretches from horizon to horizon burns brightly in some of the images. Exposures up to 30 seconds allowed enough light to enter the lens without noticeable star movement. Each location required a lot of experimenting. and different lighting techniques. Sometimes a short burst of diffused light from a flashlight was sufficient, or bounced light from multiple flashlights was used for a softer more natural glow.
