How do you say NUCLEO (de un planeta o estrella) in English?

It is not called planet/star center or nucleus (it is NUCLEO in Spanish).
The word is CORE or PLANETARY CORE. The central part of a planet or a star is called CORE (also the central part of certain fruits such as the apple is called CORE). Though the CORE is in the center of the objects mentioned before, it is not the center of such objects. It is in that position but it does not constitute the center.
A CORE, in the case of planets and stars, is the most internal layer of several that constitute the object itself with the SURFACE being the most external. Because of their position it is believed that the material of a CORE is extremely hot, much more than the rest of the planet or star. The materials that constitute the CORE may stay in a constant state of liquefaction because of the high temperatures and the tremendous weight that have to withstand because the atmospheric attraction is much stronger there. It is believed that Earth core has two sections: an outer core that is believed to be liquid and an inner core said to be solid.

The stability of a CORE is of utmost importance for the existence of planets or stars. Any condition or unsuspected factor intervening to tip off the balance in which CORES exist would most likely cause problems of such magnitude that they could easily mean the end of the whole planet or star.  
It has been said that an inactive core is synonym of a dead planet.

What are LAS TRES MARÍAS called in English?

Image
(Left to right:  Alnitak ,  Alnilam  and  Mintaka )  The TRES MARIAS is this group of three bright stars that are apparently at the same distance from one another though in reality none is at the same distance. They are called like that in most of Latin America and apparently they are called the THREE KINGS (the Magi) in the Philippine Islands. The TRES MARIAS after whom those stars are named are Mary, mother of Jesus; Mary Magdalene and Mary, the wife of Clopas (probably a relative of Jesus's). To find them in the sky means you are also looking at the constellation of Orion (the Warrior), to be more precise, its belt because that is precisely what the TRES MARIAS are called in English: Orion's Belt.

The Maps of Ship-Trap Island

Image
Once I had my high school students read The Most Dangerous Game, a short story by Richard Connell. Rainsford, the main character, is a professional hunter traveling by ship to his next hunting area, accidentally ends up in an island called Ship- Trap island. When he goes into the island he finds there are two men living in a palace in the island. One of them is a Cossack general and the other, his brutish servant.  The Cossack is called general Zaroff who is also  a game hunter but has become bored of hunting regular game and now uses the island's unique position to capture sailors from shipwrecks. He lets them go first and next after some time he hunts them down. Rainford's arrival who is worldwide famous presents Zaroff with a rare opportunity to find excitement in hunting again by hunting another hunter. Little does Zaroff know that Rainsford is The Most Dangerous Game in the World and hunting him will not be easy at all. My students enjoyed themselves at reading

How do you say NACIMIENTO NAVIDEÑO in English?

Image
"Oh no! Not another power blackout!"             NACIMIENTO NAVIDEÑO or PESEBRE NAVIDEÑO is a tradition which consists in recreating the moment of Jesus Christ's birth with small figures representing Joseph, Mary, the shepherds and the Wise Kings. Baby Jesus is set on December 25th of course, while the other figures are placed before, usually at the beginning of December.       The translation is NATIVITY SCENE, though some people only say CHRISTMAS SCENE. This last term is a bit broad -- even an image of Santa Claus riding his sleigh falls under that description. Saying CHRISTMAS NATIVITY SCENE would be perhaps more appropriate.                                                                                        Merry Christmas!
