The Pinwheel Galaxy
The Pinwheel Galaxy (Messier 101 or NGC 5457).
The Pinwheel Galaxy is located about 21 million light years away in the
direction of the Ursa Major (Big Dipper) constellation. This vibrant
astronomy picture combines data in the infrared, visible, ultraviolet
and x-rays from four of NASAs space telescopes.

spiral galaxy
Beautiful Barred Spiral Galaxy NGC 1300.
This Hubble Space Telescope image shows a spiral within a spiral: the nucleus of this spiral galaxy has its own extraordinary
and distinct, 'grand-design' spiral structure that is about 3,300
light-years long. Only galaxies with large-scale bars appear to have
these grand-design inner disks. Unlike other spiral galaxies, NGC 1300
is not presently known to have a massive central black hole.
NGC 1300 is located about 61 million light-years away in the direction of the Eridanus constellation. Its total length is about 110,000 light-years.

Explanation: In the center of star-forming region 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. These stars, known collectively as star cluster R136, were captured above in visible light by the Wide Field Camera peering through the refurbished Hubble Space Telescope. Gas and dust clouds in 30 Doradus, also known as the Tarantula Nebula, have been sculpted into elongated shapes by powerful winds and ultraviolet radiation from these hot cluster stars. The 30 Doradus Nebula lies within a neighboring galaxy known as the Large Magellanic Cloud and is located a mere 170,000 light-years away.

Witch Head Nebula (IC 2118)
Witch Head Nebula (IC 2118) is a faint
reflection nebula located about 1000 light-years away in the direction
of the Eridanus constellation. It is thought to be an ancient supernova
remnant or gas cloud illuminated by Rigel, a nearby supergiant star
located in the Orion constellation.
