Arrow Some Astronomy news

If anyone's interested...

1. They've discovered a 5th planet (a record, so far) around 55cancri one of the stars in the constellation of Cancer. This star holds a place near to my heart because I had to do a presentation at University on it. It was one of the first Earth-like stars to have been discovered with a solar system.

There's some beautiful artwork - see siggie - and information here: http://www.nasa.gov/audience/formedia/telecon-20071106/

2. Apparently a comet exploded in the region of Perseus a few days ago. This is best visible from the northern hemisphere. I don't know if anyone's had a chance to check this out?

Thanks for the heads up, unfortunately, I don't think we can get a good view here in the southern hemisphere especially since it's almost summer here.

Orion is just beautiful. And there are very familiar stars and constellations around it.

Re: Some Astronomy news

I looooove astronomy. When I was in nursery school, all the other kids were drawing some crappy stick-figure portraits of their dog, but I was drawing the solar system. WITH the asteroid belt. My teachers thought I was a weird kid.

Re: Some Astronomy news

We are many who love astronomy
This is my desktop here in my work:

It is Pluto System: Plutón, Charón, Hydra and Nix.

Last year a poster made a poll to change his name to a star name, and we helped him to choose his new name (don´t remember the star that won).

Take a look to this album I made about McNaugt (the Great Comet of 2007)

I love astronomy since I was 10 years old, I have my own telescope since last year ;D and I have loads of books.

How can a comet explode?? I thought comets were just a big ball of ice and snow.

I think the poster was Albireo?? A gorgeous double I might add, splitable with just about any scope I was thinking about getting a scope for Christmas, but I travel too much and don't have room for it Schmidt-Cassegrains and catadioptric scopes seem appealing because of their folded focal length, but I'm not sure a super-amateur like me is up to the required maintenance. Maybe I should get a pair of those giant binocs???

Re: Some Astronomy news

I can´t wait New Horizons to reach Pluto system!
I track the ship potition in space from time to time:
http://www.nasa.gov/mission_pages/ne...ain/index.html
Right now, between Saturn and Urano´s orbit, closer to the second one.

Last November 9th they woke it up from his nap (it was hibernating since August). The space ship sleeps most of the time but they wake it up to reorientate the antena and check the instruments.
It has reached 15 U.A. (15 times the distance from Earth to Sun) and is flying towards Pluto at 60.000 km/h.

It was launched 19/1/2006 and will reach Pluto on July 2015.

Maybe by exploded he meant of the effects which took place because of crashing of the comet on the planet, I am not sure though

And sorry, maybe I couldn't make you understand what I wanted to say because right now I can't remember some of the appropriate words

And I also love astronomy

You rang?

Actually, this has always been my user name, so it wasn't me.

Giant binocs are great--I have a pair of 11 x 80s--but you'll definitely want/need a tripod to hold them steady (especially the higher-power ones, like 20 x 80s).

If you want a small scope, and you have the money, try to scrounge up a TeleVue Pronto (70mm). Awesome little scopes, with pinpoint images and very little aberration. (I got mine for $900 new back in '94.) Also, Orion Telescopes has a great little 4.5" Dobsonian (the StarBlast) that runs less than $200; the 6" model is still less than $400, IIRC.

The Schmidt-Cass doesn't take a huge amount of maintenance. Get a dew-buster like the Kendrick Dew Ropes to keep the corrector plate clear. They're commonly f/10s, so collimation isn't a huge issue (it's not particularly hard anyway, but be careful which screws you turn!). I have an old C-8 on a German equatorial mount (wooden legs!), and it was pretty simple to use and care for. The corrector plates are a little trickier to clean than a Newtonian mirror, so you'd probably want someone in your local astronomy club to show you, in person, how to do it.

"If you practice for ten years, you may begin to please yourself, after 20 years you may become a performer and please the audience, after 30 years you may please even your guru, but you must practice for many more years before you finally become a true artist—then you may please even God." --Ali Akbar Khan, 1922-2009
