On NPR’s Morning Edition, I heard a story about Noreen Grice, an astronomer at Boston’s Museum of Science and President of You Can Do Astronomy. She’s been writing and illustrating astronomy books since 1990. What makes these books cool is they are written, and illustrated, for the blind. The pictures are textured, so the blind can feel them.

Her most recent book, Touch the Invisible Sky:

has images taken by telescopes that detect things like radio waves, x-rays and gamma rays — the wavelengths of light that no one can see with the naked eye.

“I think we all have the same thing in common with this book,” says Grice. “No human can see these other wavelengths so we’re all approaching it together.”

As a middle-schooler, I thought I wanted to be an astronaut, a la Sally Ride. She was the first American woman in space, aboard Challenger in 1983. And while my career plans have changed, I still have an interest in astronomy. It had never occurred to me to wonder what resources were available for people with disabilities who share that interest. Noreen’s books enable other children to dream of being astronauts.

That’s one reason why Chelsea Cook, a high school student in Newport News, Virginia, got her family to drive four hours to Baltimore for the new book’s unveiling. She says Noreen Grice’s astronomy books are “really interesting, you know, the visuals are easy to read, and they’re just cool to look at.”

Cook says she has enough vision to see a full moon, but not stars. Still, she wants to study astrochemistry and astrophysics. And she’s fascinated by the idea of space exploration.

Her ultimate career goal? To become the first “blind astronaut.” It will be “a lot to work towards,” she says, “but I think it’s possible.”

NASA is making this book available for free to schools for the blind, as well as the Library of Congress. What a wonderful way to make science accessible for everyone.

Xena, the third brightest object in the Kuiper belt, has gotten her official name, just weeks after Pluto got demoted to dwarf status. 2003UB313 is now officially Eris, named after the Greek goddess of chaos and strife. Her satellite, nicknamed “Gabrielle,” also now has an official name, Dysnomia, daughter of Eris and “spirit of lawlessness.” Michael Brown, discoverer of Eris, called the name “too perfect to resist.” Ahh, geek humor.

The International Astronomical Union voted today to redifine “planet.” Planet now means:

a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a … nearly round shape, and [has] cleared the neighbourhood around its orbit.

That means Pluto is no longer a planet because its elliptical orbit overlaps the orbit of its nearest celestial neighbor, Neptune. Pluto is instead now classified as a dwarf planet, along with Ceres (a large object in the asteroid belt), and Xena (2003 UB313), an icy body in the Kuiper Belt that’s larger than Pluto. Recent discoveries using new telescope technologies had identified several objects that were larger than Pluto, raising the possibility of as many as 50 planets. With the new definition, the solar system now includes only 8.

Neil de Grasse Tyson (who is awesome, by the way, right up there with Sagan and Gould) must be feeling some vindication today. As head of the Hayden Planetarium, he received quite a bit of hate mail from school children when their new solar system exhibit excluded Pluto in 2001. Turns out he was right all along.

I have a slight tear in my eye today, yes; but at the end of the day we have to describe the Solar System as it really is, not as we would like it to be. — Professor Iwan Williams, chair IAU “planet” committee
