Neptune’s brightness and solar variation

To those who accuse me of having a particular bias on the issue of anthropogenic global warming, I offer the following, sent my way by planetary astronomer Heidi Hammel, the subject of a recent children’s book I wrote in the “Women’s Adventures of Science” series.

Science thrives on questions that challenge the consensus view. In this case, the analysis of changes in Neptune’s brightness suggest that a solar component may be in play. If further research bears out Heidi’s hypothesis, then our understanding of Earth’s recent warming may need to be refined to include a greater role for solar phenomena than are included in the current consensus view.

Time for grassroots action

My blog has been on hiatus, and that will continue because I am directing my energies elsewhere — in my community. You can do the same in yours.

Support the Candidates that Support Science

In my book reviews, I avoid becoming partisan, but when it comes to voting, I am passionate about electing leaders who understand science, who support science, and who avoid the temptation to misconstrue science for their political advantage.

No matter what category you put it in, Pluto is as interesting as ever.

Many of my young readers are disappointed that Pluto is no longer a planet. I think its important for them to realize that the body is as interesting as ever. That’s why I revised an old “Ask Dr. Fred” question on my website for children’s science and retitled it “Why Isn’t Pluto a Planet Anymore?”

It says, in part:

August 24, 2006, was a significant day in the history of planetary science. If you read the newspaper headlines, you might think it was famous as the day that Pluto was thrown out of the planetary family. But if you read more about the 2006 meeting of the International Astronomical Union, you will discover that the story is a bit different than that. August 24, 2006, was really the first day that there was an official scientific definition of the word “planet.”
