Hoy queremos celebrar no solo a todas esas mujeres q han pasado a la historia de la ciencia sino también a todas aquellas q hacen su trabajo todos los días y q quizás no las estudiemos en los libros pero sin su aportación científica no se hubiese avanzado tan rápido.

The term "microwave" is due to the wavelength of these photons, of about 1.9 mm. Background refers to the fact that such radiation is all over the space. Wherever your radiotelescope is pointing, you will detect it.
#WeirdWednesday
The photons arriving to our eyes from the Microwave Background Radiation (MBR) are not from the origin of the Universe, as sometimes is said, but they are the oldest photons we can detect from the Universe. All the other photons we see are originated later.
@MiaDoesAstro I post it upon acceptance and I do not read any paper which is not accepted, just because some of them are not complete or right in all their aspect.
#planetTuesday
Jupiter is the largest of all the planet of our Solar System. It is so big that it is bigger (in mass) than the other seven planet together! It is located at an intermediate distance from the Sun (about 750 millions of Kms) and it is the first of the gigant

hydrogen burning. The contracting phase is called pre-main sequence. If the stars have a mass smaller than 2M. is called a TTauri while is a Herbig Ae/Be if the mass is between 2 & 8 M.

When the protostars have blown away most of its envelope it might become visible although the hydrogen burning in its core has not yet starts. No more mass will be accreted. On the contrary, it will contract until the temperature inside get the value to ignite the
However, some of them show a cuasi-elliptical form at the IR (old stellar population). Some other irregular galaxies might have this lack of shape due to interactions with some other galaxies. In this case thy might show some disturbance like tails. Or not.

#GalacticFriday
When a galaxy is not elliptical or spiral is called irregular. The name came from E. Hubble himself at the beginning of the XX century. Such galaxies have no a clear form in the bluest band of the optical spectrum.
@CronicaCultura @Perestupinya@debatelibros@LaCronicaDeHoy Absolutamente en desacuerdo!! la mayoría de las veces que he puesto el grito en el cielo por algo más "divulgado" nunca lo ha dicho un científico, nunca. Podemos decir las cosas un poco más oscuras, pero nunca decimos algo incorrecto...
