Pluto is, isn’t, is, a planet

A ques­tion at Perkins Obser­va­tory by a very intel­li­gent fourth grader reminded me recently that cer­tain sci­en­tific con­tro­ver­sies never really go away.

Learning to see

As with any wor­thy endeavor, it takes time to become a good stargazer. Even the small­est tele­scopes and binoc­u­lars are space­ships to other worlds, but you have to learn to run the controls.

Dogs in space

Sir­ius, the Dog Star, is deeply a part of our mod­ern mythol­ogy. Peo­ple still refer to the dog days of sum­mer, but few know that they are refer­ring to the bright­est star in the night­time sky. In August, Sir­ius rises with the sun. The ancient Greeks believed that the intense glow of the star added to the sun’s heat, leav­ing us with those nasty, late-summer days.

Time (keeps on slippin’ into the future)

The week between Christ­mas and New Year’s Eve is the time we think about time, and it’s about time that we reflect on this most puz­zling aspect of astronomy.

A Christmas message

Recent events at Sandy Hook Ele­men­tary School in Con­necti­cut remind me of the neces­sity of our mis­sion at Perkins Observatory.

More Bull about Jupiter

If any­one is expect­ing me to write about the Mayan apoc­a­lypse sup­pos­edly com­ing up on the Win­ter Sol­stice, Dec. 21, then you will be dis­ap­pointed. The sup­po­si­tion is so much bull that it isn’t worth the expen­di­ture of ink or elec­trons to dis­cuss. But speak­ing of bull, an event is occur­ring there that is wor­thy of observation.

Observing with that Christmas telescope

The hol­i­day sea­son is upon us. Most folks are filled with the joy that rises out of mass con­sump­tion, but I am feel­ing a few mis­giv­ings. I know that more than a few tele­scopes and binoc­u­lars will be sit­ting under trees on Dec. 25. Many of these mar­velous opti­cal instru­ments will sit idle until March as their own­ers hud­dle with cold-weather dread inside their houses.
