Explanation:
Una estrella de unas 38 veces la masa del Sol y otra ligeramente inferior, de unas 32 masas solares, están tan cerca que comparten una única envoltura. Ambas orbitan alrededor de un centro de masas común, y acabarán fusionándose en una única estrella supermasiva, dicen los científicos, de unas 70 veces la masa del Sol. “Será dentro de algunos millones de años, ni siquiera decenas de millones de años, y tenga en cuenta que eso no es apenas nada en términos astronómicos… nuestro Sol tiene 4.500 millones de años de vida”, explica a EL PAÍS Javier Lorenzo, astrónomo de la Universidad de Alicante y líder del equipo que ha descubierto y caracterizado está sistema binario. MY Camelopardalis, situado, en la constelación de la Jirafa, está a una distancia de entre 12.000 y 15.000 años luz de la Tierra, en nuestra galaxia.

About RBC</h3>
RBC stands for Red Blood Cells. They are also called erythrocytes. They are circular, biconcave, disc-shaped and non -nucleated cells. They are formed in red bone marrows and destroyed in the spleen. Their lifespan is very short that is 4 months.
RBC contains an iron pigment called haemoglobin that carries oxygen from place to place in the form of oxyhemoglobin. When haemoglobin is exposed to oxygen, it turns red. So the blood is red in colour. If RBC is less in blood then, a person is suffering from anaemia , as there is not enough haemoglobin to transport oxygen.
