November Roses and the Southern Sky

CCPs Rose Tub

I just got back from a week’s vacation in sunnier climes and was surprised to see one of my rose gardens still blooming after a snowstorm and some chilly rain while I was gone. We’ve had something of a mild autumn this year in New England, and some flower gardens are still glowing madly away, basking in the last warm weather before the snows start in earnest. This little tub of roses is dedicated to the memory of Caroline Robinson, late wife of Leif Robinson — a former colleague of mine from Sky Publishing. She loved to garden, and when I was planting these little Canadian roses earlier this year, I thought of her and her fight against cancer. A few weeks ago we attended Caroline’s memorial service and I thought about these roses out there, still blooming this late in the year.

Another set of blooms arrived in my computer’s inbox today — this set from the European Southern Observatory. These roses are really giant clouds of glowing hydrogen gas coloring the space in the Large Magellanic Cloud — a satellite galaxy of our own Milky Way. This European Southern Observatory image captures the beautiful sight of a 1,000 light-year-wide HII region (consisting of hydrogen gas being lit by radiation from 40 very bright bluish-colored stars) called N44. Astronomers studying this cloud think that some supernovae have exploded in N44 during the past few million years, “sweeping” the surrounding gas away from the supernova sites. Hot stellar winds from other massive stars in this area are blowing bubbles in the surrounding gases, twisting the material into wispy filaments and bright knots.

A small programming note: regular readers of this blog may notice that I’m fiddling around with the layout and template design. I hope to be through messing around with it soon but I do appreciate your patience while I figure out what I’m doing!

Also, have a look over at the library and gift shop on my website. I’ve been adding some holiday gift ideas at the suggestion of several readers who have been writing to ask me about the perfect gift for that stargazer they know. I’ve got links to books, telescopes, binoculars, star charts, space music and many other items — some with links to Amazon.com (which itself has loads of details about these products as well). Happy browsing!

Astronomy and Cats

In 1990 I wrote a planetarium show about a space cat. His name was Larry (after our own Lawrence E. Katt, who was with us from his birth in 1982 until his passing in 1999) and he had all kinds of adventures. Now we have three other cats (Pixel, Miranda, and Lazarus Long), and they’re all sort of astro cats in one way or another. Pixel is named after a Robert Heinlein cat character who plied the spaceways with Maureen Johnson Long. Miranda is so named because her mottled coloring reminded us of the Uranian moon Miranda.

And Laz (our newest addition) is named after another Robert Heinlein character who also plied the spaceways through a number of novels. What is it about cats and space? Would they do well on long voyages, in weightlessness? Would they travel well? I’ve always wondered about taking a cat on a cruise ship. Seems like a good companion to have on those days when all you want to do is slip into your cabin and relax…

Of course there are cats in astronomy. The constellations Leo Major and Leo Minor come to mind.

Aside from the constellations, cats show up in the cosmological tales of such civilizations as the Aztec, where their Jaguar God Tezcatlipoca rules the stars as god of the night sky and the winds of night. His name really means “smoking mirror”, which gives him a sort of magical aspect.

And of course, there is Bastet, the cat deity who was both goddess and protectress of cats and the people who lived with and cared for cats. While not exactly a deity associated with the stars, she was important in her own right — and I like to think of ancient Egyptians out stargazing with their cats by their sides!

So, how do cats figure in today’s stargazing? Hard to tell. Probably they don’t care much about what their humans are doing outside, as long as food regularly appears and the humans let them out to help during backyard stargazing sessions. I have a friend who used to brag that he kept a kitten in each pocket to keep his hands warm during long periods at the telescope. Our own cats don’t go outside (we live near a wooded area that is home to many critters that see cats as a tasty main dish), but they do like spend time indoors crawling around on the telescope base for my Dob and sleeping on the case for my 6″ Sovietski scope. But perhaps our cats are the exception. Maybe your cats go out stargazing with you ” and spend their evenings watching YOU scan through Leo or Lynx looking for excitement, adventure, and deep-sky objects! They’re great observers too — while you’re watching the universe, they’re watching YOU.
