An angiogram uses X-rays and a special dye (contrast) to take pictures of the arteries in your brain, heart, and kidneys. The dye is injected into a small tube or catheter into an artery in your groin or (sometimes) your arm.
As the cloud collapses the force of gravity drawing the cloud inward gradually becomes stronger because the strength of gravity follows an inverse square law with distance. hoâ¦pe that helps.
Beyond the line of ice, the temperature drops below 260 k and the water molecules, ammonia, hydrogen sulfide, carbon dioxide and methane are all condensed. The gravitational collapse on large nuclei surrounding gas - mostly hydrogen and helium - formed the giant planets (Jupiter, Saturn, Uranus, Neptune). Around these small systems, many small icy objects (satellites) were able to regroup. Jupiter attracted so much gas that eventually reached 318 Earth masses.
