A shower of shooting stars cometh

 

N’oubliez pas, cette nuit une pluie d’étoiles filantes
“Et si la vie était une étoile filante traversant une sombre éternité, chacun aurait le loisir de la faire briller à sa guise.”
Torino Benacquista

Do not forget, this night, a shower of shooting stars
“And if life was a shooting star travelling through a dark eternity, everyone would take the leisure to make it shine as they please.”
Torino Benacquista

Phases of the moon

 

The phases of the moon are caused by the light from the sun and the moon’s orbit around the Earth. From new moon through waxing crescent, quarter, gibbous, full moon, and waning back to new moon again…

Making a star

.
.
Simulation of star formation by collapse of molecular clouds (2008). The calculation models the collapse and fragmentation of a molecular cloud with a mass 50 times that of our Sun. The cloud is initially 1.2 light-years (9.5 million million kilometres) in diameter, with a temperature of 10 Kelvin (-263 degrees Celsius).

Solar system


The Solar System was formed approximately 4.6 billion years ago and consists of the Sun, planets, dwarf planets and other astronomical objects bound in its orbit. The formation was cause by the collapse of a giant molecular cloud, the mass at the centre collecting to form the Sun and a flat disc of dust around it which the planets and other bodies would eventually be formed from.

99.86% of the system’s mass is found in the Sun and the majority of the remaining 0.14% is contained within the solar system’s eight planets.
