Astronomy is very much a work in progress and our understanding of it is still lacking. Several topics in astronomy are well understood, others are approximated by complex models and simulations. Up to very recently …
Proxima Centauri is the closest star to our own Sun, and for the last 4 years there have been several hints pointing to an exoplanet orbiting it. Not just any planet, an Earth like planet. …
While they seem to be eternal, even stars have a lifespan. At the end of this lifespan they can die in several ways depending on their mass. Perhaps the most spectacular star death is the …
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 …
The image above shows an artists’ impression of what the surface of the super-Earth orbiting Barnard’s Star might look like. However, given that the planet receives only about 2% of the light Earth receives from …
Alphard (Alpha Hydrae) is an orange-colored star that 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 …
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, …
