100 Days Project

Tukara: 100 days of doodling

My goal is to get back in touch with my long lost drawing skills. I aim to complete one doodle a day for the next 100 days.
*Update* My new project and goal is now to sketch one of the 100 most influential people of last century each day. This will give me an opportunity to learn more about these individuals and what they were known for. The 100 individuals are taken from the collection by TIME Magazine and information taken from Wikipedia.

Day 31:

Day 31 - Edwin Hubble

Edwin Powell Hubble was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as one of the most important observational cosmologists of the 20th century. Hubble is known for showing that the recessional velocity of a galaxy increases with its distance from the earth, implying the universe is expanding. Known as "Hubble's law", this relation had been discovered previously by Georges LemaƮtre; a Belgian priest/astronomer who published his work in a less visible journal. There is still much controversy surrounding the issue and some argue that it should be referred to as "LemaƮtre's law" although this change has not taken hold in the astronomy community.

Hubble is also known for providing substantial evidence that many formerly known "nebulae" were actually galaxies beyond the Milky Way. American astronomer Vesto Slipher provided the first evidence to this argument almost a decade before.

Hubble supported the Doppler shift interpretation of the observed redshift that had been proposed earlier by Slipher, and that led to the theory of the metric expansion of space. He tended to believe the frequency of light could, by some so far unknown means, decrease the longer light travels through space.
