New Look

I’m trying out a new, minimalist look.

The Pages sidebar is now on the left behind a slider and the keyword search is at the end of the first batch of posts.

Suns and Galaxies

keplerA member of Year 9 has told me that she’s fascinated by astronomy, as am I.  So, I’m going to post a few interesting links from time to time here which I happen to have seen and enjoyed myself. I liked this video about the Sun in particular and this link to NASA images is  changed every day. Finally, there’s links in the sidebar to the space telescope Hubblewatch’s weekly podcasts, so you can listen to the most up-to-date information. The Kepler mission to search for habitable planets is well worth a listen. The image is of the Delta rocket sending Kepler into space, where it will gaze at a patch of sky for over three years, looking for the dimming of starlight as a planet passes between it and a star, perhaps like our Sun.  Enjoy.

Blue Bananas

bluebananasBananas look blue in ultraviolet light. The colouring might be due to the breakdown of chlorophyll – the stuff that makes plants look green -as the fruit ripens. Some animals can see in the shorter wavelength UV, so it might be a means of attracting them.

Would you eat a blue banana?

This image isn’t real. Amazing what can be done with Photoshop…
