APRIL NIGHT SKY 2021 -- STARGAZING GUIDE & KEY DATES The most noteworthy aspect of this view is the warped inner disc of the spiral galaxy. The core of this spiral galaxy contains an unusually energetic 40-million solar mass black hole that is churning up the material in its immediate surroundings, thus distorting the inner disc and creating the enormous streamers of pink-glowing material in the galaxy’s inner regions. STAR FACTS: MIZAR AND ALCOR Mizar is in fact a four-star system, while Alcor is a binary system in its own right, which means that the entire system consists of six stars, in which a two-star system orbits a four-star system once every 750,000 years or so.

We know them today as Mercury, Mars, Venus, Jupiter, and Saturn, while our solar system’s other two planets (not including the Earth), Uranus and Neptune, were not formally discovered until 1781 and 1846 respectively using telescopes.
