The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 trillion miles. A pair of planet-hunting satellites — NASA’s Tess and the European Space Agency’s Cheops — teamed up for the observations.
The Solar System orbits the center of the Milky Way in the same way as Earth orbits the Sun. According to Interesting Engineering, our Solar System takes around 250 million years to complete a single revolution while traveling through space at speeds of over 515,000 mph (828,000 kmph).
According to the best current knowledge, the Milky Way is about 100,000 light-years across, about 2,000 light-years deep, and has 100 to 400 billion stars. There may be four primary spiral arms
Milky Way Star Clusters and Gaia: A Review of the Ongoing Revolution Tristan Cantat-Gaudin Max-Planck-Institut für Astronomie, Königstuhl 17, D-69117 Heidelberg, Germany; cantat@mpia.de Abstract: The unprecedented quality of the astrometric measurements obtained with the ESA Gaia spacecraft have initiated a revolution in Milky Way astronomy.

28. In the Milky Way galaxy, the most recent observed supernova appeared in 1604. 29. Never in the history of humanity has there been more people living on this relatively small planet. 30. Because of the mobility of Americans today, it is difficult for they to put down real roots. 31.

For visual observation it is best to use a fast telescope, such as a large aperture, f/5 Newtonian telescope or faster. Binoculars are the best for recreational and easy observation of the sky and the milky way. 8×40 and 10×50 binos do provide a very bright image and can easily be used handheld.
