#SolarSystem facts : The Solar System consists of the #Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. 99.86% of the system’s mass is in the Sun.
“I am done with great things and big things, great institutions and big success, and I am for those tiny, invisible molecular moral forces that work from individual to individual, creeping through the crannies of the world like so many rootlets, or like the capillary oozing of water, yet which if you give them time, will rend the hardest monuments of [a person's] pride.” --William James
The Bubble Nebula really is a bubble. It is being blown into this shape by the bright star known as SAO20575, which sits just to the left of centre in this image. This is a giant star of 10–20 times the mass of the Sun.
Electrospray ionization - Charged particles fly to counter electrod. Solvent evaporated so only analyte enters. Analyte flies into Mass analyzer. m/z ratio calculated for determination of molecular mass down to 0.01%.
Celestial Finger Painting This colour-composite image was obtained by FORS1 on ANTU. It displays a sky area near the Chamaeleon I complex of bright nebulae and hot stars in the constellation of the same name, close to the southern celestial pole
