A massive neutron star only 30 kilometers across but with a mass 2.17 times that of the Sun has been discovered 4,600 light years away from Earth. MSP J0740+6620 is therefore the most massive neutron […]
Alphard (Alpha Hydrae) has an apparent visual magnitude of +2.0, making it the brightest star in Hydra, the largest of the 88 recognized constellations. Alphard is at the midway point to becoming a bright giant […]
Caph (Beta Cassiopeiae) is a yellow-white Delta Scuti-class variable, F2-type giant star in the constellation Cassiopeia, with an apparent visual magnitude of +2.27. Along with the stars Alpheratz (Alpha Andromedae) and Algenib (Gamma Pegasi), Caph […]
Unlike most other prominent naked-eye stars, the star Gamma Cassiopeiae does not have a traditional Latin or Arabic name, which is strange considering that the star is relatively bright with a mean apparent magnitude of […]
Schedar (Alpha Cassiopeiae) is a second magnitude star in the constellation Cassiopeia which despite its “Alpha” designation appears to be marginally dimmer than Beta Cassiopeiae (Caph), depending upon which frequency is used to measure Schedar’s […]
Algol (Beta Persei), known informally as the Demon Star, is a triple star system in which the components are designated Beta Persei Aa1, Aa2, and Ab, respectively. The Algol system is not only the first, […]
Mirfak (Alpha Persei) is a yellow supergiant located about 510 light years away in the constellation of Perseus that is about sixty times bigger than our sun. It is the most luminous star in the […]
There’s a star located 1,280 light-years away in the constellation Cygnus that has been confusing astronomers ever since it was discovered in 2015 during the Kepler mission. The star, officially called KIC 8462852, is 50% […]
The Sun really does not need an introduction, except to say that it is not yellow, but pure white, and that it is not an average star. In fact, there are no average stars, as […]
Alpheratz (Alpha Andromedae) is the brightest star in the constellation Andromeda with an apparent visual magnitude of +2.06, which also makes it the 54th brightest star in the night sky. While this binary system properly […]
