Scientists have been looking for clear pictures of newborn planets for a long time so they could provide the evidence needed for theories of planetary formation: that planets coalesce in a ring of dust surrounding young stars.
For years, they could not differentiate between planets and other masses in the images and relied on very vague evidence such as “gaps”; these were dark rings in the bright mass of dust surrounding stars that scientists thought were being formed as a planet revolves around the sun and gathered surrounding material to grow.
However, this year they were finally able to take a clear picture which has the potential to reveal much more than they originally thought it could. When pictures were taken of two newborn planets of a star PDS-70, the planets were found to have a surrounding ring of dust which may be an initial stage in the formation of moons.
Most of these observations are recorded by using the Very Large Telescope (VLT) that is a set of four large telescopes placed on a mountaintop in Chile’s Atacama Desert. By viewing these embryonic planets, not only we will have evidence of planetary formation but also the evidence of moon formation.
