Giant Exoplanet Found Orbiting Tiny Red Star Challenges Space Theories

A red dwarf star called TOI-6894, located 238 light-years away, hosts a giant planet despite existing theories suggesting such large planets shouldn't form around such small stars. This discovery challenges current models of planet formation, with further studies planned using the James Webb Space Telescope to understand the planet's atmosphere and origin.

Giant planet found orbiting tiny red star challenges planetary formation theories

Scientists discovered a massive planet, TOI-6894b, orbiting a low-mass red dwarf star, challenging existing theories of planet formation, as such large planets were thought unlikely to form around such small stars. This finding suggests many more giant planets may exist around small stars in the galaxy, prompting a reevaluation of current models.

Astronomers Discover Youngest Exoplanet Defying Cosmic Norms

The discovery of TIDYE-1b, a three-million-year-old exoplanet, challenges existing models of planetary formation, which typically assume a much longer development period. Located 430 light-years away in the Taurus molecular cloud, TIDYE-1b's rapid nine-day orbit and chaotic protoplanetary disk suggest a dynamic formation process, possibly influenced by nearby stars or environmental factors. This finding implies that planets can form and evolve more quickly than previously thought, offering new insights into the diversity and complexity of planetary systems.

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.

"TOI-1685 b: Discovery of a Hot, Rocky Super-Earth"

An international team of astronomers has confirmed that TOI-1685 b, a super-Earth exoplanet discovered in 2021, is a hot and rocky planet with an Earth-like density. Using data from NASA's TESS and various ground-based facilities, they determined that TOI-1685 b has a radius of 1.47 Earth radii, is three times more massive than Earth, and has a high equilibrium temperature of about 1,062 K. The findings suggest that TOI-1685 b is not a water world but may have a high mean-molecular weight atmosphere.
