Serendipitous Stargazing

We’ve had an unexpected (but welcome) warm spell here in the Northeast U.S. today. That means later on I can go out and do a little warm-night skygazing at the spring stars overhead. It’s not often we can do that in April around here. And, actually, there’s a good chance that it’ll cloud up and rain sometime soon, so I don’t want to lose the opportunity! In this stargazing business, you have to grab your chances when you can!

A few years ago I remember going out in downtown Boston (I lived in the North End for a short time) and being amazed to find Comet Hale-Bopp! It was bright enough we could see it from the middle of all the city lights. In fact, Mark and I grabbed the wait staff at the restaurant where we’d just had dinner and showed them the comet. Of course, it wasn’t all that warm (being late March at the time), but the generous impulse was appreciated. People respond to nifty cool things like being able to see a comet from a spot where, by all rights, they shouldn’t have a chance. A friend of mine who lives in New York City has regaled me with tales of taking her little scope out to a park near her place and showing people Mars and Saturn and Jupiter and the Moon. So, you never know when you might get a chance to see a celestial sight — and maybe share it with somebody!

Ship’s Keel

The Carina Nebula
The Carina Nebula

In 2001 we went on a cruise around South America and I was the ship’s astronomy lecturer. My job was to help the paying passengers do some stargazing and give them some fun lectures about the stars. It was great fun, and I had a marvelous time getting to know the Southern Hemisphere skies along with my shipmates. One of our favorite areas to look was the constellation Carina, which harbors the great luminous blue variable Eta Carinae. This (probable) double star system is on the verge of tearing itself apart, and when it does the view should be spectacular.

The Nebula itself is made up of cast-off material from the star system, and there is evidence of star-forming activity inside the clouds. So, the whole area is being watched with great interest by those who want to understand the mechanics of starbirth and stardeath.

Of course we couldn’t see any of this from the ship — our view was “limited” to the gaspingly beautiful southern Milky Way and the Magellanic Clouds and all the other sights we don’t get much chance to see from the Northern Hemisphere. The sky is just full of great stuff to study, and if you travel a lot, it enhances your visits to other lands.
