Night Sky Astronomy

I was out on November 3rd at  a Fireworks show in Trispen in Cornwall and whilst I was waiting for the Fireworks to start I was having a good look at the Sky.  It was clear as a bell and a very cold evening, so the Stars were shining brilliantly. To my amazement, I saw a really bright and big shooting star followed by another, and another, and another and another. I think I saw a total of 6 or 7 in the end and they were all really clear to view, and were flying across the Sky right above us! It was an amazing sight as I wasn’t expecting to see a Meteor show as well!

A few days later I looked up whether there were any Meteor showers taking place around this time and found that the Meteors must have been from the Leonids which is a Meteor shower that happens throughout November every year. The best days to view them this year were on the 17th and 20th of November, so I was very lucky to see as many as I did in only about 45 minutes of viewing, a good couple of weeks before the height of the shower.

The Leonids are said to be a lot better quality than the Perseids in August as they are much brighter and about 10mm in diameter, and this was certainly true from my observations. The Perseids paled in comparison to the Leonids. These Meteors originate from a Comet named Tempel-Tuttle, which was discovered in 1865 by Ernst Tempel, and radiate from the constellation Leo (hence their name).

Remember to keep an eye out for them next year as they are a great sight to behold!

The weather forecast was not good for the actual height of the Perseid meteor shower (it turned out to be shocking) so I went out and had a look the day before, which was last Saturday. It turned out to be a strange half hour or so!

When I first went to look outside there was a massive flash of lightning which made me jump as I wasn’t expecting it, so I assumed that the sky would be completely cloudy, but I was surprised to see that the sky was in fact mostly clear. So I went on out and had a good stare at the sky above.  During the star gaze, lightning was still flashing in the distance somewhere over Dartmoor, which made it interesting. In fact, the lightning turned a bit strange at one point as it seemed to be pulsing in one cloud only! It was like the scene in Independence Day when the alien ships first started to appear out of the skies around the world.  The flashes were quick as well – no more than 10 to 15 seconds apart, so there must have been one heck of a storm over Dartmoor somewhere!

Luckily this weird lightning storm didn’t take anything away from the meteors as I saw some amazing ones shoot across the sky.  On some, the ‘tail’ that they left was very distinct and easy to see well after the meteor itself had vanished! I think in the time I was out there (not much more than half an hour or so), I saw 6 or 7 meteors with probably 3 or 4 of those being really big and bright. Add to this, I saw the ISS again (purely by accident this time) and 6 other satellites, which meant it was a great time sky gazing! In fact, a couple of the meteors were up there with the best I have ever seen, although the one I saw in Weymouth last September was still the best ever as it was very bright and large as it streaked across the constellation of Cassiopeia.

Did anyone else manage to see any Meteors or the strange lighting storm? Send me a comment or tweet me (@strethewey) if you did!

Finally we have had a break in the miserable weather and I have been able to go out and have a look at the night Sky again!

Luckily the clearer night skies have coincided with the time of the year when the International Space Station is most visible in our region.  Last night I saw it for the first time this year and it was as good as it was in 2011.  This year it seems to have changed its trajectory in the sky as it came in from towards the Hoe and travelled towards Yelverton, wheras last year it came from the direction of Cornwall and right over the top of our house towards the edges of Dartmoor. I would recommend to anyone to have a look each evening for it. It is currently coming into view in Plymouth for several minutes between 21:30 and 23:00, but you will have to check for exact timings. Once you see it in the Sky, then you know what it is straight away as it is much brighter than anything else and it is moving at a constant speed. If you can get hold of some binoculars you should be able to see the solar panels on each side of the main pod with ease.

It is also the time of year for the annual Perseid Meteor Shower. This year the height of the shower is on the 12th and 13th of August. I am hoping the evenings will stay clear enough on those nights to view them, however I will be out before and after those dates as you will still be able to see the miniscule dust particles light up the night sky, but less frequently. They originate from the Perseus Constellation which is basically looking towards Dartmoor from anywhere in Plymouth, so can easily be seen.

During the month of August the ISS (International Space Station) could be seen in the sky during most evenings. The first time that I saw it was on Sunday 21st August when my family and I were on holiday in Weymouth. I wasn’t sure what to expect really as I didn’t know how bright it was going to be and how easily it could be made out from the rest of the stars in the sky. I had a NASA app on my phone which gave the general direction of where the ISS would be coming from and the length of time it would be viewable in the sky, but I was still worried that I wouldn’t see it.

Whilst on the look out, I was scanning the sky generally for constellations and satellites and to my amazement saw the best two shooting stars I had ever seen in my life.  These were obviously not actual shooting stars but were two meteors from the Perseid Meteor Shower. This was especially great as the height of the meteor shower was a couple of weeks before, so these would have come from the tail end of the passing shower and were totally unexpected. They were so bright and the trails in the sky were long and wide. It was brilliant to see and completely lucky that I was looking at that area of the sky at the right time. I knew these were part of the Perseids as their general direction originated from towards the constellation Perseus, and from my position, they shot past in front of Cassiopeia as well.

The image below is the best image I can find that shows almost exactly what I saw in the sky.

Not long after, I suddenly spotted a very bright light in the sky coming from the direction where the ISS was meant to originate from. The object was moving as well which meant that what I was seeing was the ISS, and it was bang on time (the app gives the time of when the ISS becomes visible in the sky). Where I was watching was in the direct path of the ISS, so it flew directly over the top of me which was great to see!  Looking at it you could just make out the solar panels and the general shape which made it an amazing sight. It lasted for about 4 minutes before it passed by and faded to black as it moved away from the sun (which was reflecting off the panels which is why it was visible in the sky).  After seeing this, I was out most evenings when the sky was clear to view the International Space Station pass overhead, and I would recommend the viewing to anyone as it is a great thing to experience and puts a lot of things into perspective.  Unfortunately, now we are in mid-September, the ISS has moved out of viewable range in the evenings although it can be seen for a fleeting moment during the early hours of the morning on occasions.

The sighting of the International Space Station also cleared up a little mystery from earlier in the year when I was out at Mount Batten in Plymouth and saw a very bright object move across the sky at a fairly brisk pace.  At the time I wasn’t sure what it was and thought it may have actually been a UFO, but after seeing the ISS during the Summer, I can now say that what I saw in March was the ISS travelling across the sky above us. Am glad this has been cleared up although it would have been nice if it was a UFO!  😉

The Perseid Meteor Shower (the ‘Perseids’) will reach its peak activity on Saturday 13th August this year. Unfortunately, this coincides with a full moon this year which will make the sky so bright that only the closest and largest meteors will be seen.  But don’t ignore it for this year, as it will still be possible to view them!

The Perseids originate from the constellation Perseus, but actually have nothing to do with any of the stars in the constellation. They are actually rock fragments left over from the comet Swift-Tuttle when it last flew near the Sun. So if you can find the constellation of Perseus in the night sky, you will know where to look for the meteors streaking across the sky.  However, don’t just look at the constellation, look at the area around it as you will still be able to see them as they only originate from Perseus.

Let’s hope for a clear sky and good viewing to everyone!
