The Pleiades: the seven cosmic sisters

When we speak of the Pleiades we refer to a set of celestial objects that have been mentioned by many civilizations throughout history. Also known as The Seven Sisters, these Pleiades are an open cluster that contains stars of spectral type B, of young age and located in the constellation of Taurus. They are also known as M45 or Messier 45. How to see the Pleiades? Throughout human history, there have been many civilizations that have mentioned the existence of these celestial constellations. To see this set of celestial objects we have to locate the constellation of Orion in the sky. Once located, we must follow its star to end in the constellation of Taurus and they will be easily divisible. Astronomy experts recommend December and January to contemplate the Pleiades in all their magnitude in our sky. In addition, they are observable with the naked eye, so we do not need any special equipment to see them. The Seven Sisters During ancient times there were many civilizations that observed these types of stars in the sky. The Greeks called them “doves” and this is where the myth of The Seven Sisters arose. Chronicles are told that these seven sisters are daughters of Atlas and Pleyone. In this myth it is said that the seven of them took their lives and that it was the god Zeus himself who turned them into stars to leave them immortalized in the sky after their death. Many gods of Olympus such as Ares, Zeus or Poseidon fell at the feet of these seven sisters for their beauty.The Seven Sisters that the Greeks knew were: Taygeta: triple star system that is at a distance from the Earth of about 440 light years .Astérope: the Greeks described her as one of the weakest sisters since she is one of the least brilliant of the seven. Alcyone: the brightest and most noticeable of all the sisters of the Pleiades. It is estimated that it shines about 1,400 times more than the Sun and can move at great speed: 215 kilometers per second. Electra: the third brightest of the sisters, she is considered a giant star. Celeno: it is the farthest star of the sisters about 562 light years from Earth. Merope: with a temperature of 12,300 degrees on its surface, Merope is also one of the brightest since its luminosity can be up to 630 times that of the sun. Maya: known as “blue giant”, Maya is located 385 light years from Earth and is the one that can best be seen given its luminosity and proximity to our planet.

The first polarized X-ray map of Cassiopea A

Cassiopeia A is a supernova remnant approximately 11,000 light-years distant from Earth.

Neutron stars aren't really stars.

Neutron stars are not true stars, although, thank goodness, they are made of neutrons.

Ready to see the Orionids? Tonight will reach the maximum peak of 'shooting stars'

Don't forget to look at the sky this Friday night. Up to 20 meteors per hour are expected.

Detected a brutal cosmic explosion that sweeps the Earth (the origin?)

This spectacular phenomenon was captured by multiple telescopes around the world. What came out of that event? Astronomers believe that it is the birth of a black hole.

A black hole is 'vomiting' material from a star it devoured years ago

Astronomers had never seen anything like it. The radio waves appeared three years after the star was swallowed.
