“Twinkle, twinkle little star, how I wonder what you are.”  

How far is far? To help put ‘space’ in perspective, Chandra X-ray Observatory takes us on a journey from some of the smallest to some of the largest distances in our universe.

The clearest way to define distance is as “the amount of space between two points.” But how far is far?

This short video compares distances from the very small to the very far, from the distance between gravitational waves to the distance to some of the farthest galaxies.

An interesting digital resource to include into your science lesson.

And why 'Chandra' telescope?

Chandra X-ray Observatory is in orbit around the Earth. It was launched in 1999. And next year marks the 20th anniversary of NASA's Chandra X-ray Observatory launch into space.

“Twinkle, twinkle little star, how I wonder what you are.” 

Roger Brissenden outlines some recent successes of the telescope and discusses the achievements of Subrahmanyan Chandrasekhar the Indian born astrophysicist after whom the telescope is named. 

Arguably the greatest astrophysicist of the twentieth century, his name is in every astronomy book. From the upper mass limit of a white dwarf, Chandrasekhar’s limit, to the orbiting Chandra X-ray telescope, he left his mark on the very concepts and vocabulary that physicists and astronomers use today. He received the Nobel Prize in 198.

Teachers, visit Chandra X-ray Observatory website. There are featured resources, app, interactive games, activities and quizzes that you can explore into your lessons.

As well, at the end of every month I put together a list of the most popular posts. You will find posts written in English and Portuguese. 

And now, it's time to the review of the most popular posts of March:
    Here are the most popular posts of the last month:

Wherever you are, I hope you are happy to come back to school after Easter holiday.
Thanks all the educators from around the world who kindly continue to read my blog every day. 

The classroom must be an open window to the world. Students must feel free to talk and share ideas about all the subjects they care about, in and around every curriculum.

Have a nice time wherever you are! Here, rainy time!
