Closest Earth-Sized Exoplanet Discovered Just 22 Light-Years Away

Scientists have confirmed the existence of an Earth-sized exoplanet, LTT 1445 Ac, orbiting a small red dwarf star just 22 light-years away. Although too hot for life, its similarity to Earth makes it an important target for studying planet evolution. The exoplanet resides in a trinary system, making it challenging to observe. However, using the Hubble Space Telescope, researchers were able to obtain high-resolution transit data, determining the exoplanet's diameter and density. Further characterization of LTT 1445 Ac can provide insights into the formation and evolution of Earth-like worlds and the potential for life elsewhere in the galaxy.

Possible Discovery of Dark Matter Planets and Rogue Earth-Neptune Pair.

Scientists have theorized that planets made of dark matter could exist and have laid out how they could be detected. These hypothetical planets could be detected through transit data and radial velocity measurements, which could reveal anomalies in their properties that defy our current understanding of planet formation. defy our current understanding of planet formation. The researchers also suggest that the light curve of a dark matter exoplanet could be distinguishable from that of an ordinary exoplanet due to its tiny but non-vanishing interaction strength with Standard Model particles. Further study is needed to set bounds on dark matter exoplanet abundance if they are not detected.
