Astronomers Unveil Youngest Known Planet, Challenging Formation Theories

Astronomers have discovered one of the youngest planets ever, TIDYE-1b, at just 3 million years old, using NASA's TESS telescope. This discovery challenges existing models of planetary formation, as TIDYE-1b is visible despite being surrounded by a protoplanetary disc, which usually obscures such young planets. The planet's tilted orbit relative to its star and disc offers new insights into early planet formation, suggesting planets can form earlier than previously thought.

"Planetary Origins: Young Planets Resemble Flattened Smarties, Not Spheres"

Astrophysicists from the University of Central Lancashire have discovered that young planets have flattened shapes like oblate spheroids rather than being spherical, challenging previous assumptions. Using computer simulations, the researchers found that protoplanets form as flattened structures called oblate spheroids, similar to smarties, and grow predominantly from their poles rather than their equators. This finding has important implications for understanding planet formation mechanisms and suggests that observations of young planets through telescopes may depend on the viewing angle. The researchers are now working on improved computational models to further examine the shape and chemical composition of these young planets.

"Study Reveals New Planets Resemble Flattened Smarties"

Researchers at the University of Central Lancashire (Uclan) have used computer simulations to model the formation of planets and found that young planets formed around stars have flattened shapes similar to Smarties, contrary to the previous assumption that they were spherical. The study, published in the journal Astronomy & Astrophysics Letters, revealed that young planets are oblate spheroids, with implications for viewing planets through telescopes and understanding how they form.
