Una Mirada a las Incontables Estrellas / A Look at the Countless Stars

Con muy pocas excepciones, todas las estrellas que podemos ver a simple vista pertenecen a nuestra propia galaxia, la Vía Láctea. A pesar de que los poetas hablan de las "innumerables" estrellas visibles, de hecho menos de 4.000 estrellas se pueden ver en un momento dado a simple vista. Veamos algunas de ellas, y de paso, unos globulos estelares, dentro y fuera de la Vía Láctea.

With very few exeptions, all the stars we can see with the unaided eye belong to our own galaxy, The Milky Way. Although poets talks of the "countless" visible stars, in fact less than 4000 stars can be seen at a time with the unaided eye. Lets see some of them and some globular clusters from our Milky Way and beyond.

A mere 4.3 light-years distant, Alpha Centauri actually consists of two component stars similar in size to the Sun, locked in a mutual orbit, and a third star (Proxima Centauri) going around this two

Orion's Belt

In the Great Nebula of Orion (M42) lies the star known as Theta1 Orionis, but actually is not an star, it is a bright star cluster known as the Trapezium

In the constellation of Aquila (the Eagle), lies a star nearing the end of its life that is surrounded by a starfish-shaped cloud of gas and dust

The binary star system Eta Carinae

The central star of NGC2440 is one of the hottest known, with a surface temperature near 200,000 degrees Celsius

Star Cluster Omega Centauri

The core of the star cluster in NGC 3603 is shown in great detail in an image from the Wide Field Planetary Camera 2 (WFPC2) camera on the NASAESA Hubble Space Telescope

Star Cluster NGC 1850 is a young globular star cluster located some 168,000 light years away in the Large Magellanic Cloud

Nicknamed the Southern Pinwheel, M83 is undergoing more rapid star formation than our own Milky Way galaxy, especially in its nucleus.  Hundreds of clusters and tremendous activity
