The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Galileo made studies of sunspots, the Milky Way, and made various observations about stars, including how to measure their apparent size without a telescope. [78] [79] [80] He coined the term Aurora Borealis in 1619 from the Roman goddess of the dawn and the Greek name for the north wind, to describe lights in the northern and southern sky when ...
The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars. The Sun is part of one of the Milky Way's outer spiral arms, known as the Orion–Cygnus Arm or Local Spur.
The Milky Way started out small and grew in size as it merged with other galaxies, gaining stars as well as hydrogen to form more stars. Each galaxy has hydrogen gas that aids in the birth of stars.
Night on the Galactic Railroad (銀河鉄道の夜, Ginga Tetsudō no Yoru), sometimes translated as Milky Way Railroad, Night Train to the Stars or Fantasy Railroad in the Stars, [1] is a classic Japanese fantasy novel by Kenji Miyazawa written around 1927. The nine-chapter novel was posthumously published by Bunpodō (文圃堂) in 1934 as ...
Orion Arm. The Orion Arm, also known as the Orion–Cygnus Arm, is a minor spiral arm within the Milky Way Galaxy spanning 3,500 light-years (1,100 parsecs) in width and extending roughly 10,000 light-years (3,100 parsecs) in length. [2] This galactic structure encompasses the Solar System, including Earth.
The term was coined by Steve Mandel who defined them as "high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way. As a result, these nebulae are incredibly faint, taking hours of exposure to capture.
Later in the 1920s, Edwin Hubble showed that Andromeda was far outside the Milky Way by measuring Cepheid variable stars, proving that Curtis was correct. It is now known that the Milky Way is only one of as many as an estimated 200 billion ( 2 × 10 11 ) [7] to 2 trillion ( 2 × 10 12 ) or more galaxies in the observable universe.
