The Milky Way bar is made of nougat, topped with caramel and covered with milk chocolate. It was created in 1923 by Frank C. Mars and originally manufactured in Minneapolis, Minnesota. The name and taste derived from a then-popular malted milk drink ( milkshake) of the day, not after the astronomical galaxy.
Galactic Center. 17 45 40.04, −29° 00′ 28.1″. The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
The Perseus Arm is one of two major spiral arms of the Milky Way galaxy. The second major arm is called the Scutum–Centaurus Arm. The Perseus Arm begins from the distal end of the long Milky Way central bar. [1] Previously thought to be 13,000 light-years away, it is now thought to lie 6,400 light years from the Solar System.
Harlow Shapley (November 2, 1885 – October 20, 1972) was an American scientist, head of the Harvard College Observatory (1921–1952), and political activist during the latter New Deal and Fair Deal. [1] [2] Shapley used Cepheid variable stars to estimate the size of the Milky Way Galaxy and the Sun's position within it. [3]
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.
Barnard's Star is the star with the highest proper motion. [1] In astronomy, stellar kinematics is the observational study or measurement of the kinematics or motions of stars through space. Stellar kinematics encompasses the measurement of stellar velocities in the Milky Way and its satellites as well as the internal kinematics of more distant ...
Nearly 6% of Americans have cognitive disabilities such as autism and dementia, which can cause difficulty concentrating or making decisions. To create accessibility for people with these ...
A gravitational-wave detector (used in a gravitational-wave observatory) is any device designed to measure tiny distortions of spacetime called gravitational waves. Since the 1960s, various kinds of gravitational-wave detectors have been built and constantly improved. The present-day generation of laser interferometers has reached the necessary ...
