Colliding GalaxiesIt was assumed that all types of galaxies had formed in the distant past with those shapes and that they had kept those shapes up to the present. Considering that the distances between galaxies are only about 100 times larger than their diameters and that they move through space with relative veloci

After radio astronomy had come of age and was able to determine the positions of radio sources in the sky with greater accuracy, it turned out that several radio sources coincided with faint blue “stars.” The peculiar term ., short for quasi-stellar radio so

Interstellar matter consists mainly of hydrogen and helium left over from the immediate aftermath of the Big Bang, with some heavier chemical elements created in early generations of stars. The disks of spiral galaxies have an abundance of interstellar matter: in some places, it is thin and

Since the 1970s, attempts have been made to obtain resolved images of stars using sophisticated optical and mathematical methods. But it was still exciting
