Neptune holds many mysteries but thanks to an old spacecraft
and scientists using ground based telescopes we have an idea of what lurks inside of the strange ice giant. So lets put on our super science fiction space suits and dive directly into Neptune! But what will we find????

Falling into Neptune description -
As you fall towards Neptune you would have an incredible view of the planets immense storms raging below you. You would be descending at a similar speed to if you were falling towards Earth, as Neptune's Gravity is only 14% stronger than our own planets. Because you are so far away from the sun, very little light reaches this distant part of the solar system, resembling a dim twilight back on Earth. You would first fall through high white, cirrus clouds made of methane ice crystals, at about 0.5 atmospheres, which is half the atmospheric pressure at sea level on Earth. At this altitude it is incredibly cold, dropping to below -200 degrees Celsius (-350degrees Fahrenheit). Around 30 miles down you would enter into the ammonia and hydrogen sulphide cloud decks at about 5 atmospheres. Hear the clouds move faster than the speed of sound on Earth, as Neptune experiences the fastest wind in the solar system, reaching speeds of up to 1500 miles per hour. But because of your super science fiction space suit, you are kept steady and continue on your descent. Because of Neptune's thick clouds and distance from the sun, no light can penetrate this deep and you would find yourself in a pitch black, cold, lonely environment, with violent winds whipping past your helmet. After falling for a long time you would be 100 miles into Neptune, when huge flashes of lightning illuminate your dark surroundings, revealing towering white water ice clouds that are causing rumbling thunderstorms to occur. As you pass through this cloud stage the pressure would increase to well above 50 atmospheres and the temperature would be around 26 degrees Celsius. Using your hi tech science fiction helmet you can now see whats around you, but you would quickly realise that the cloud layers where the easy part of the adventure. As you emerge from the bottom of the water ice clouds the pressure would become intense and the temperature would drastically increase to above 1000 degrees Celsius. After a very long time of sinking you would be around 4000 miles in to Neptune and within the planets mysterious mantle layer. Hear your suit would have to withstand pressures greater than 10,000 atmospheres and increasing temperatures higher than 4000 degrees Celsius. This strange super heated layer is composed of water, methane and ammonia ices that behave as a hot dense fluid under immense pressures. Because of these extreme pressures carbon atoms might also crystallise and form diamonds. As you descend ever closer towards Neptune's core, these diamonds would rain down around you like glittering hailstone, as they slowly sink through the liquid mantle. After a long time of sinking through this thick region, with the pressures and temperatures continuing to drastically increase, your adventure would come to an end. Thousands of miles into the planet you would be standing on Neptune's core, a surface roughly the same mass as Earth and made of rock, iron and exotic ices, possibly with a layer of nestled diamonds. In this region you would be stranded, unable to travel further and unable to escape. You would be doomed to spend the rest of your life in a scorching environment with your science fiction suit having to withstands temperature of above 5000 degrees Celsius and pressures of above 7 million atmospheres.
