Stars have always been part of civilizations. In Ancient Times, we relied upon the apparent motion of these bodies to navigate distances, to measure the passage of time therefore determining seasons, months, and years. Simply, stars are the very reason we exist. We are literally made up of “stardust”.
In the constellation Libra about 190 light years away from our planet, reside one of the most mysterious objects in our galaxy, the impossible star which appears to be older than the universe itself.
The most mysterious star in the universe KIC 846852 still baffling scientists. We have no idea what’s going around this bizarre star and maybe we’ll never know for sure; the only thing we can do is just to exclude the many-proposed hypotheses.
Everything in the universe comes to an end, and our sun is no exception. In five billion years from now, the sun will become a huge orange giant star, so large that it will engulf the orbits of Mercury and Venus.
Our sun is really huge some 1 391 400 km in diameter, but 4 billion years from now, it will be even larger, 150 times its current size; though compared to the biggest stars in the universe even this will be small.
In a relatively distant place, approximately 1,480 light years away from Earth, sits one of the most controversial objects in our galaxy, KIC 8462852, as its dubbed, clearly becomes the primary subject of much ongoing research.
The first stars in the Universe, so–called Population III or Pop III stars, are believed to have formed from the primordial ‘molecular’ clouds, a metal–free gas available in the very early Universe, in pristine conditions.
Astronomers have discovered a hot-Jupiter planet orbiting a red giant star on a circular orbit, a unique system that serve as a perfect laboratory for planet formation and migration theories.
KIC 8462852, aka Tabby’s star located 1,480 light years away from us, has puzzled astronomers with its erratic dimming, a dimming pattern never seen before — more than 20% of its light was being blocked out by something!
The Hypergiant red star VY Canis Majoris, one of the largest stars in our galaxy, is going to die soon, new study suggests. Will it impose some risks to our planet as it dies in violent supernovae explosion?
Just 29 light-years away from us, the star AU Microscopii can be described as a close neighbor. This red dwarf, which is ‘only’ half the mass of our Sun, lies in the southern constellation Microscopium — unfortunately, is not visible in the northern hemisphere.
By using Gaia satellite, a team of scientists, with a little help from amateur astronomers, have found an extremely rare star system: a binary system where one star completely eclipses the other, the first of its kind ever discovered.
