About this deal
But there is a hope that it may even be possible to get a closer look at one of these Oort Cloud comets with a space mission.
Sahara space rock 4.5 billion years old upends assumptions
But with Voyager 1, which launched more than 40 years ago, still only a one-tenth of the distance from the edge of the Solar System to the Oort Cloud and unlikely to make direct contact with anything there unless it crashes, getting such samples could be a long time coming.A solar system crystal ball is a decorative object that features a miniature model of our solar system inside a crystal sphere. This enormous shell of objects is thought to start somewhere around 190 billion miles (306 billion km) to 470 billion miles (756 billion km) from the Sun. Scientists found that the hibonite crystals had lots of helium and neon atoms, a result of being bombarded by tons of energetic particles from an infant Sun.

SIX Lighting Modes: (Slow Flashing Multi-Coloured;Fast Flashing Multi-Coloured;Constant White Light,Red Light,Blue Light and Green Light). Because it decays over time, we can use it to date events – particularly within the first four or five million years of the Solar System’s life. Still other achondrites, including Erg Chech 002, are “ungrouped”: their parent bodies and family relationships are unknown.In any case, Kööp is happy that the helium and neon atoms managed to stick around inside these tiny crystals for so long. The decay of aluminium-26 is also important for another reason: we think it was the main source of heat in the early Solar System. Over a period of millions of years, the Earth (out of all other planets surrounding the Sun) may have been the only ‘Moon like world from Saturn’ that could have had the capabilities of converting itself into a biological, evolutionary life sustaining environment. To confirm whether the Sun went through an active phase like this, scientists have been studying the chemical composition of meteorites to look for tell-tale signs of reactions caused by energetic particles. Kööp and her collaborators conclude that since these noble gases couldn’t have bonded into the crystals as they formed, the helium and neon atoms they found in hibonite crystals must be the products of this splitting caused by high-energy particles.
