Sirius – Why Does it Twinkle

Sirius – The Twinkling Star

Orion and Sirius Credit Adrian West

During the winter months and around this time of year, after dark we in the northern hemisphere are able to see the mighty constellation of Orion rise high in the sky with a very bright companion in a nearby constellation: Sirius – The Dog Star.

Sirius is the brightest star in the sky and can easily be found in the faint constellation of Canis Major to the left and below Orion. Its name comes from ancient Greek meaning “glowing” or “scorcher.”

Sirius (a CMa) is the alpha star in this trusty hound and is roughly 8.5 light years away from Earth, making it one of the closest stars to us. It has a tiny companion star making it a binary system composed of “Sirius A” the main component (which is a white main sequence star) and “Sirius B,” a white dwarf star. As seen with the naked eye, Sirius can be seen to twinkle many different colours low in the winter evening sky. Read the rest of this entry »

Dark Sky Bucket List: Part 1

Originally posted on Dark Sky Diary by Steve Owens @Darkskyman on twitter

Astronomy tourism is a burgeoning field – luckily for me, as it’s how I make a living! – with city-folk now starting to make the effort to travel to places with darker skies, in the hope of seeing things that simply cannot be seen from the orange glare of a town sky.

Galloway Forest Dark Sky Park, which I helped establish in 2009, has seen a lot of this dark sky tourism trade, due to its high profile in the media, but many other places around the country – Sark in the Channel Islands, and Exmoor National Park to name but two – have followed suit, hoping to attract the stargazing crowds.

And as more and more people come out of the city for a stargazing weekend under dark skies it’s becoming clear to me that there’s a real appetite for seeing the Milky Way and other elusive dark sky objects. It’s almost become something to put on your “bucket list”: see a wild lion in Africa; fly in a hot air balloon; see the Milky Way.

However there are lots of other amazing astronomical objects visible under a dark sky so here is the first installment of my top-ten “Dark Sky Bucket List”. Read the rest of this entry »

Scopeless not hopeless

A blog for us AMATEUR amateur astronomers. By @RadioVicky.

Bio:

I’m 33, I live in Bristol and I like astronomy.  However, I don’t have a telescope and even if you did give me one, I’d be uncertain where to put my eye. I write comedy and I’m a professional blogger. My favourite colours are beer and dark skies.

Telescopes scare me. Not in the way a stranger in my bedroom or a spider in my knickers would scare me, but they do fill me with a certain fear.

I mean, I absolutely love things that go *shine* in the night, and have since I was a little girl, but the prospect of going out and buying a scope – something I know NOTHING about — is fairly petrifying. It even makes me feel a bit of a fraud. How can I be in to astronomy when I don’t even know my azimuth from my elbow? And also, I’m not too hot on my constellations either – sure, I know the main ones they teach you at school, but ask me to point out Lyra? Pegasus? Lucky Jim’s Pirate Ship?

OK, I admit it, I’m an AMATEUR amateur astronomer, but so is 99.9999999999999999999999% (possibly more nines than that, I didn’t have time to conduct a survey) of the world’s population, so it’s a cool club to be in.

Before I got friendly with astronomers on Twitter, I always fancied one of those thin tubular ones they sell for £90 in Argos. Surely I would be able to see the storms on Jupiter, the arms of Andromeda, and the Bristol football team practicing from 10 miles away? Turns out I’d be better off peering through a toilet roll tube with some cling film on the end of it – I’ve been told that cheap telescopes merely turn unimpressive white dots into marginally less impressive WOBBLY white dots, so I’m saving the cash for a Virgin Galactic space holiday instead. I hear the weather’s quite exceptional on Mercury…

But something happened this weekend that made me feel better about scope envy. I’ve been getting friendly with our very own @virtualastro on Twitter, and when I discovered I had 900 free minutes to use before the end of the month, I thought it was nigh on time we spoke to each other.

So, I called him up, and we spent a total of FIVE HOURS on the phone over the course of Saturday and Sunday night. Rest assured Twitter, we have plotted and planned some very exciting things together which will be blazing your way like a comet made of ideas instead of muddy ice soon …but the best, most wonderful, amazing, magical thing we did was…GO STAR HOPPING TOGETHER. Without a freakin’ telescope!

Even though we are about 70 miles apart (I live in Bristol, he lives in Oxfordish somewhere) we were both able to look up at the same sky, see the same ISS passes, and the same meteors. It was remarkable to be on the phone to someone with such an incredible knowledge of the skies. I sat gob smacked, mouth and ears open, as he talked me through constellations, clusters, satellites and gory Greek myths. I had no idea Cassiopeia had been a naughty girl and was sentenced to dangle upside down on a chair for eternity. I’d never heard of the Cygnus Rift — an ominously dark patch of sky in our milky way. I couldn’t even pick out the summer triangle, but now I know where it lives I will undoubtedly point it out to people in the pub, spilling cider as I leap around, trying to remember which stars make it up.

The best part was a dazzling ISS pass with a Perseid meteor streaking past like an arrow through a love heart. @VirtualAstro even had to put the phone down to deal with the deluge of tweets, and it felt amazing to be part of something so communal, so magical, yet so fleeting.

He also reassured me I didn’t need a telescope to enjoy the skies – which is fabulous because I was getting a bit sick of wishing for one on every meteor I saw. He said ‘if you look up at the sky…then you’re already an astronomer,’ a line which neatly castrated the last traces of my scope envy.

As I lay back and looked at the star-flecked sky, with crickets singing in the hedge, and Adrian firing me up with a guided tour of our resplendent heavens, it dawned on me. This was better than any naughty phone chat line. He could quite easily wire up a premium-rate number to his phone and charge £1.50 a minute for the pleasure of his knowledge.

Yep, I had a great time star-gazing without a scope last night. To the point of rubbing my thighs and drooling a bit. And how was it for you, darling?

Vicky pretended she was having fun looking through the telescope, but the view was better with just her eyes.
