The Hubble Space Telescope was able to detect a complex dust structure stretching 150 billion miles around the young star HR 4796A. Interestingly, the design resembles the planetary system around a star with an age of 8 million years.
Scientists used the NASA Hubble Space Telescope to find a large-scale, complex dust structure with a length of 150 billion miles. It is located around the young star HR 4796A with an age of 8 million years. It is surprising that the design strongly resembles the initial stage of the formation of the planetary system.
Most likely the field of fragments was formed due to the impacts between the developing planets near the star. This is confirmed by a bright dust ring, 7 billion miles away from the star. Starlight, exceeding the sun by 23 times the brightness, influenced the dust and pushed it into space.
However, the dynamic continues. The elongated outer dust structure resembles an inner tube in the shape of a donut that fell under a truck. It seems more extended in one direction, so it looks pinned down. Perhaps the reason is the movement of the main star, or it is the result of the influence of the neighbor - the red dwarf HR 4796V, which is 54 billion miles distant from the first star. Dust distribution acts as a control signal of how dynamically the internal system interacts with the ring. It is important to understand that contact with the interstellar medium and the power of stellar neighbors influence the evolution of such systems. Coarse asymmetries of external dust suggest that many different forces are involved in the game, moving the material.
The first official evidence of the presence of dust discs around the stars arrived in 1983. Later in the pictures also found the disc around the Beta Painter. In the late 1990s. Hubble’s second-generation tools have learned to block the glare of central stars and capture a variety of disks.
