Echoes of Carl & A Pale Blue Dot

Echoes of Carl & A Pale Blue Dot


Cassini's Pale Blue Dot (credit: Cassini/JPL/CalTech/NASA)


It is often said that:

a picture is worth a 1000 words

The great champion of space, science, adventure, and exploration, Carl Sagan coined the phrase: a pale blue dot to describe how the Earth would appear from the vastness of space. The Jet Propulsion Laboratory at CalTech in Pasadena released a photograph that answers this question. It was captured by the Cassini space probe while in orbit around Saturn nearly 900 million miles distant. Cassini's image echos Sagan's famous quote and offers a noble tribute to him.

It is also is an example of how existential an image and statement can be in this era of amplified climate change and environmental degradation. It is especially appropriated on Earth Day. Sagan's complete existential thoughts about 'a pale blue dot' are a reminder to deeply ponder. WHB
