Celestial Wonders- Binary Stars.
The twins of the stellar world are binary star systems.A binary star is a star system consisting of two stars orbiting around their common center of mass.When two stars appear close together in the sky, the situation is known as an “optical double”. This means that although the stars are aligned along the same line of sight, they may be at completely different distances from us. This occurs in constellations; however, two stars in the same constellation can also be part of a binary system.
Artist’s impression of the sight from a (hypothetical) moon of planet HD 188753 Ab (upper left), which orbits a triple star system( yes, a Triple Star system!). The brightest companion is just below the horizon.
Binary star systems are very important in astrophysics because calculations of their orbits allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated. This also determines an empirical mass-luminosity relationship (MLR) from which the masses of single stars can be estimated.
It is estimated that approximately 1/3 of the star systems in the Milky Way are binary or multiple, with the remaining 2/3 consisting of single stars. The Brightest star in the sky is a binary.
This is true. When it was discovered in 1844 by the German astronomer Bessel, the system was classed as an astrometric binary, because the companion star, Sirius B, was too faint to be seen. Bessel, who was also a mathematician, determined by calculations that Sirius B existed after observing that the proper of Sirius A (the main star) followed a wavy path in the sky, rather than a uniform path. Sirius can now be studied as a visual binary because, with improving technology and therefore improved telescopes, Sirius B was able to be seen, although not for 20 years after Bessel had correctly predicted its existence.
Black Holes in a binary System ?
The term “binary system” is not used exclusively for star systems, but also for planets, asteroids, and galaxies which rotate around a common center of gravity. However, this is not a trick question; even in star binaries, the companion can be a black hole. An example of this is Cygnus X-1.
The universe is pretty amazing huh?…
you ask what I have done with my life. why I am 22 with so many unfinished selves. so many futures I could not commit to. but you don’t know how much of my time has been spent keeping myself alive.

omg the tag isn’t even off the bed yet! ;w;
This cat looks and sounds like a very very tiny mountain lion
Our culture really romanticises the idea of a brooding misunderstood loner who’s an asshole to everyone but secretly has a heart of gold, so it’s frighteningly easy to meet a guy who treats everyone around him badly and believe without evidence that he has a heart of gold.
Don’t fall for it.
And a lapse in cruelty is not evidence of kindness.
“A lapse in cruelty is not evidence of kindness” Bolded because that line is so incredibly important
I agree with Bernie Sanders on every substantial issue but he can’t win so I’m not going to vote for him
a bunch of people whose votes could severely diminish his supposed unelectability, which you’re all intelligent enough to realize is a media narrative based entirely on optics, not substance, and in defense of corporate interests. Aren’t slick, focus-group tested, styled, coached, talking-point drones in ever-enlarging flag pins exactly what we’re so tired of?
Decades of advocacy for the underrepresented don’t outweigh a bad haircut and a goofy accent?
Take the opportunity to cast a vote you’re proud of!
