Rather different is the famous, and unexplained "Milky Braid", a band of diffuse white light that crosses the sky. ... At any given time, from and particular point on Klovia, you can only see half of it, but the full braid goes all the way, 360 degrees, around the sky. ... Let's say you see a dot of light. ...

... A reconstruction method of 3D vector velocity field (three components of velocities) of gas in disks of spiral galaxies from observed line-of-sight velocity field is proposed. This method is based on Fourier analysis of observed velocity field. ... The knowledge of velocity field in spiral galaxies allows to clarify the nature of the galactic structures and mechanisms of their formation. ...

... Observers looking at an object that is moving away from them see light that has a longer wavelength than it had when it was emitted (a redshift), while observers looking at an approaching source see light that is shifted to shorter wavelength (a blueshift). ... By measuring the amount of the shift to the red, we can determine that the bright galaxy is moving away at 3,000 km/sec, which is 1 percent of the speed of light, because its lines are shifted in wavelength by 1 percent to the red. ... Part 2...
