Artie Aardvark Goes to Greenwich

Artie Aardvark told me to stop working so hard on revising my paper to post about his adventures in Greenwich already.  So here you go!

What an exciting day- I am in London, and off to see the Royal Observatory in Greenwich!  This might be the most famous observatory in the world because the prime meridian runs through here- the line that all the countries agreed to use when it comes to measuring locations on Earth from East to West.  It’s also the place from where people define Greenwich Mean Time, which is the global standard for time in the world.  It sounds like a really important place to visit!

Artie Aardvark Jaunts to Jodrell Bank

 

Last weekend I had my 15 minutes of Internet fame with a front page AMA about astronomy on Reddit.  Exciting times!  So in honor of that I decided to skip ahead and hand the mic off to Artie Aardvark, who’s been bursting to tell us all about his adventures in England a few weeks ago.

If you’re new to this blog, yes, Artie is an aardvark, and my group’s project mascot.  He comes with my on astronomy adventures, as he can explain what he sees far better than I could.  Enjoy!

Today is an exciting day: I am off to Jodrell Bank Observatory in England to see all the radio telescopes!  Jodrell Bank is one of the most important radio observatories in the world, with some of the biggest radio telescopes you can find anywhere.  It is south of Manchester in the country, with a lot of sheep and cows all around.  Look there in the distance- is that a radio telescope?

Time to turn off cell phones so they don’t interfere with the sensitive radio telescopes- we must be getting close!

Of course, once we get to the observatory it’s pretty obvious!

This is the Lovell telescope, which is the third biggest steerable radio telescope in the world.  Wow!  The dish is 250 feet across at the top, and they use it for a lot of research things like pulsars, which are the spinning cores of stars that exploded in what is called a supernova.  Astronomers study the neatest things!

Unfortunately I couldn’t see the telescope in action, as it was undergoing maintenance and it was stowed pointing straight up for this.  But I did find a model in the observatory showing just what the telescope would look like if you could see the top part.

Then I got to work, keeping an eye on some data coming in to the observatory…

Be careful though not to get too curious and be stuck behind this door in the control center!  This giant door looked like a safe to me, but was actually where a lot of equipment like the computer servers for the observatory are kept.  This is because they give off a lot of radiation in radio frequencies the astronomers are studying, so they have to be kept in a special vault to make sure the signals from them don’t get out.  Jodrell Bank still worries about a lot of things like that- the astronomers are forever complaining that you can’t have a wifi network for example!

(Editor’s note: the SKA office is next door to the observatory building though, and they have wifi. Conclude what you will!)

IMG_2855

Here’s the observatory building from the outside- that “little” radio telescope isn’t all that little at all, as it’s 42 feet across!  Astronomers use it to monitor the Crab Pulsar, which is left over from a supernova explosion about a thousand years ago.  In fact, people all over Earth recorded seeing this explosion as there was a “guest star” in the sky!  The Crab Pulsar gives of all kinds of radiation to this day, and astronomers are studying the system constantly in order to learn more about young pulsars.

I also went for a walk towards the back of the building and saw radio telescopes everywhere!  This telescope is called Mark II, and was being repainted by workers when I visited. All telescopes have to be painted in England else they’ll rust, and astronomers choose white to reflect as much of the sun as possible from the dish.  Mark II isn’t actually used on its own much like the other telescopes, and instead is usually used with a bunch of other radio telescopes around the world networked together- a trick astronomers use to get more detailed images called interferometry.  Jodrell Bank is a huge center for a place to process all these signals.

IMG_2845

There are all sorts of other telescopes to explore at Jodrell Bank though!  This one looked pretty crazy to me- it’s a test project to have a student telescope for students from the University of Manchester.  It’s hard for me to believe that radio telescopes can look like this, but they were in fact testing it when I visited by listening to radio signals from the sun!

All told, I had a really fun time visiting Jodrell Bank and seeing what radio astronomers do!  But all too soon it was time to go, and catch a train to London- Yvette promised to take me to the Greenwich Observatory next!  Oh boy!

Artie Aardvark Navigates to Noordwijk

Per tradition of this blog, my experiences last week at the Dutch astronomers conference is handed off to the mascot of my project, Artie Aardvark.  Take it away, Artie!

Last week I was very excited, as it was time to meet up with all my good friends in Dutch astronomy at the NAC, the annual Dutch astronomers conference.  Hooray!  NAC is in a different place every year, and this year it was in Noordwijk, which is near Amsterdam in the middle of the area famous for tulip fields in spring.  Because it’s not that far from Yvette’s apartment in Amsterdam- Google Maps said it would take two hours of bicycling- but a bit of a hassle to get to with public transportation, I decided to go to the conference by bicycle.  I hope the Astrobites poster is secure enough for the ride!

During the ride I discovered this is a very pretty part of Holland, and in fact probably the area people imagine when they think of when they think of the Dutch countryside.  There were lots of bicycle trails everywhere, and canals, and even flower fields!

20140528-113529-41729695.jpg

There are also a lot of little roadside stands like this in this part of Holland, at the end of the driveways for the farms.  You can buy flowers directly from the farmers by putting money in the little box on the side, which I thought was really cool.

20140528-113528-41728741.jpg

Finally after two and a half hours of biking- I guess Google Maps doesn’t take into account the fact that aardvarks can’t pedal as fast as humans*- I made it to the conference, poster and all!  Hooray!

I must say, the NAC is a very good conference to attend if you are learning all about astronomy like me and are curious about many things.  This is because it is small with about 200 scientists and students this year, and you can learn about a lot of different topics.  My favorite talks were about a young pulsar who had a companion that might be another pulsar, and the discovery of an extrasolar planet with rings over four hundred times bigger than those of Saturn.  That’s more than the distance from the Sun to Venus!  Amazing!

When the talks were done, though, it was time to have fun with all my astronomer friends!  First we found a geocache next to the hotel disguised to look like a log next to a tree…

And then because we were near the beach, we went there to enjoy the spring sunshine!

20140528-113530-41730279.jpg

Afterwards, I was really hungry and decided to have a snack…

20140528-113530-41730634.jpg

And got up my energy for the bowling competition later that night!  My friend Dario even won a prize for having one of the best bowling scores!

20140528-113531-41731208.jpg

 

This was also my least favorite part of the conference, though, because while Yvette stopped paying attention to me for a few minutes I was aardvark-napped by some other astronomers!  Luckily I was found and safe the whole time, but it was scary!

Anyway, at the end of the conference, it was time to cycle back to Amsterdam.  This time I took a different route, along the sand dunes by the North Sea.  It’s probably the most isolated area I’ve seen in Holland… and also the hilliest!  It might not look like much, but the bike is a single speed so some of those dunes felt steep!

20140528-113531-41731539.jpg

I was also surprised at one point to see a lot of antennas poking out of the dunes, and discover a huge radio listening station!  Apparently it was used to receive signals when the Dutch still had colonies in the East Indies and other far away places, and also by the Germans in World War 2 to listen for their U-boats.  You can pick up all sorts of far away signals when next to the ocean due to special conditions there.20140528-113532-41732796.jpg

Finally, after the dunes I turned in towards Haarlem to catch the train home from there- you can bike all the way back to Amsterdam, of course, but that ride is not very interesting and I was getting a little tired by this point.  There was still a lot to see though, because between the North Sea and Haarlem a lot of rich Dutch merchants hundreds of years ago built country houses.  A lot of them look like palaces to me!  This was the view of Elswout, which I found when a little lost on the bicycle path.  It is very neat how in Holland even when you get lost you find the nicest, prettiest places…

20140528-113532-41732173.jpg

Finally, when I got home, I went straight to my bookshelf for a nice long nap.  NAC is good, but left me NACered by the end of it!

Feet in the Sand- Curacao

IMG_1778

Artie Aardvark sits in the shade, adjusting his sunglasses against the glare of the azure ocean.  He sips a mojito, awaiting word on the wire from Havana…

Ok, I did not bring the aardvark– he has a “don’t ask, don’t tell” policy in place on holidays, and only comes along for work for some reason- and this is about as far away from work as one can get.  Curacao!  I’m writing this on my balcony looking south over the Caribbean Sea where I’m told Venezuela lies about 60km away (not that you can tell other than the giant oil refinery on the island and the standard beer here being Venezuelan), spending a week with my feet in the sand when not scuba diving.  So a rather nice week getting acquainted with the fishes when not reading an inordinate number of books I never manage to read at home.

Also I will note because I’m proud of it that this trip was made possible thanks to my writing last year.  It is immensely satisfying to ponder the exact shade of blue of the ocean and think of how you’ve graduated to a “nice scuba diving holiday in the Caribbean” level of writer, believe you me!

The aardvark scowls in frustration at the paper delivered by his assistant, and orders another drink.  He ponders the problem facing him in great detail.

“Yes,” he muses, “yes… I would look really good in a Panama hat.”

Artie Aardvark Looks at La Palma

For those who don’t know him, Artie Aardvark is my little friend who is very curious and likes to visit various astronomy sites. Naturally when he heard about the La Palma observing run, he was begging to go…
IMG_1248

I am so excited, I get to visit La Palma and see what astronomers do!  La Palma is an island in the Canary Islands off the coast of Morocco where a lot of Europeans come for vacation, and here I am relaxing with them on the beach a little before heading up to the observatory on the summit.  I am worried though- it’s cloudy!  Won’t the clouds make observing stars hard?IMG_1253

IMG_1260I soon learn the secret of La Palma though is the mountain is so tall and steep that we are above the clouds here!  Wow!  I can’t wait to visit all the telescopes! Continue reading

Artie Aardvark Sees Santorini

For those of you who don’t know him, Artie Aardvark is my curious little aardvark friend who is the mascot for our radio astronomy group.  He likes to tag along on astronomy adventures and write about them in a far cuter way than I ever could.  Take it away, Artie!

IMG_1219

Wow it’s a good life being an astronomy project’s mascot- the astronomers had a conference here in Santorini and they brought be along!  This is the view from the conference center.  I think it might be the prettiest place in the world to have a conference. Continue reading

Artie Aardvark’s Belgian Beer Adventure Continues

Artie is my super curious little aardvark friend who comes along on adventures where astronomers go, like our brewery weekend in Belgium.  Part 1 of his adventure can be found here.

The last day of the Belgian weekend I was super-duper excited in the morning cause we were going to visit a famous Trappist brewery called Westvleteren.  Westvleteren monks only sell enough beer to cover the costs of the monastery so even though some people call it “the best beer in the world” it is super-duper hard to get your paws on some.  But it turns out not to be so hard if you go to the monastery and buy some at the tasting room!
