What’s the brightest star you can see in the sky tonight? If you live below 83 degrees north latitude, the brightest star in the sky is Canis Alpha Majoris, orSirius. Seriously, (bad pun intended) the -1st magnitude star is usually the fifth brightest natural object in the sky, and s...

which makes it the closest single star after the sun. Due to this proximity, it's commonly known by the name of Proxima Centauri. While its dimness makes Proxima a telescope-only object, its parent Alpha Centauri A and B, seen together, make up one of the brightest stars in the sky. ...
Themass of a staris an important factor in the object's stellar evolution because it determines the star's core temperature and how long and hot the star will burn. Astronomers can calculate the mass of a star based on its brightness, or luminosity, but this was challenging for Sirius B....
From this, it also knows that for a distant object to appear in focus, it must be very large. This close-up of the Harvest Moon was snapped in Calgary, AB, on September 13, 2019. Credit: Siv Heang So, when we see a bright Full Moon hanging crisp and clear in the sky ...
Usually I connect SkySafari wirelessly to my Losmandy G-11 to do a go-to an object selected on the iPad. But in this case I'll use your maps to determine its location relative to a prominent background star. Then I'll have the mount go-to the location (RA & Dec) of that star....
