April 25 2015 Astronomy Newsletter


Hi everybody

Here's the latest article from the Astronomy site at BellaOnline.com.

Columbus and the Flat Earth Myth
Doesn't everyone know that in the 15th century people thought the Earth was flat? And that brave Christopher Columbus sailed westward from Spain to get to Asia to show that the Earth was round? Once I'd have answered “Yes” to both of these questions, but it turns out that they are myths.

*How Eratosthenes calculated the circumference of the Earth*
Here's the video link that I put on the Astronomy forum: https://www.pinterest.com/pin/250090585534428857/

But I can also recommend this page from Windows to the Universe: http://www.windows2universe.org/the_universe/uts/eratosthenes_calc_earth_size.html
It has an explanation and an animation. You can also choose to read it in Spanish.

*Ode to Hubble competitions – the winners*
It was 25 years ago this week that the Hubble Space Telescope was deployed. The two Ode to Hubble competitions were part of this silver anniversary celebration. One category was for the over 25s and the other for the under 25s, those who had been born after Hubble. Here are the links to the winning entries and runners-up: http://www.spacetelescope.org/projects/Hubble25/odetohubble/

I hope to hear from you sometime soon, either in the forum or in response to this email message. I welcome your feedback!

I wish you clear skies.
