The Hubble Sequence Throughout the Universe's history

NASA, ESA, M. Kornmesser

This image shows "slices" of the Universe at different times throughout its history (present day, and at 4 and 11 billion years ago). Each slice goes further back in time, showing how galaxies of each type appear. Image released August 15, 2013. [Read the Full Story]

Present Day Universe

NASA, ESA, M. Kornmesser

This image shows a "slice" of the Universe as it is today. The shape is that of the Hubble tuning fork diagram, which describes and separates galaxies according to their morphology into spiral (S), elliptical (E), and lenticular (S0) galaxies. Image released August 15, 2013. [Read the Full Story]

The Universe 4 Billion Years Ago

NASA, ESA, M. Kornmesser

This image shows a "slice" of the Universe some 4 billion years back in time. The shape is that of the Hubble tuning fork diagram, which describes and separates galaxies according to their morphology into spiral (S), elliptical (E), and lenticular (S0) galaxies. Image released August 15, 2013. [Read the Full Story]

The Universe 11 Billion Years Ago

NASA, ESA, M. Kornmesser

This image shows a "slice" of the Universe some 11 billion years back in time. The shape is that of the Hubble tuning fork diagram, which describes and separates galaxies according to their morphology into spiral (S), elliptical (E), and lenticular (S0) galaxies. Image released August 15, 2013. [Read the Full Story]

The Hubble Tuning Fork — Classification of Galaxies

NASA & ESA

The American astronomer Edwin Hubble, developed a classification scheme of galaxies in 1926. he diagram is roughly divided into two parts: elliptical galaxies (ellipticals) and spiral galaxies (spirals). Hubble gave the ellipticals numbers from zero to seven, which characterize the ellipticity of the galaxy: "E0" is almost round, "E7" is very elliptical. Image released October 6, 1999.
