This research encompasses a thorough examination of 5595 confirmed exoplanets listed in the Archive as of 10 March 2024, systematically evaluated according to their calculated average surface temperatures and stellar classifications of their host stars, taking into account the biases implicit in the methodologies used for their discovery. Machine learning, in the form of a Random Forest classifier and an XGBoost classifier, is applied in the classification with high accuracies. The feature importance analysis indicates that our approach captures the most important parameters for habitability classification.

In all likelihood, in the next 25 years, we’ll find evidence of life on another planet.

the researchers worked out the spread of the masses for more than 3,500 microlensing events

The UV radiation rates emanating from the host star in the TRAPPIST-1 system are large enough to have caused the planets to have hemorrhaged large amounts of water over time. The inner planets of the system, TRAPPIST-1b and -TRAPPIST-1c, could have lost more than 20 times the amount of water contained in Earth’s oceans over the course of 8 billion years.

these planets are so close that some scientists think microbes could potentially hop from planet to planet and colonize the system outright.

In 1671, Giovanni Cassini gazed through a telescope at Saturn, and discovered a number of incredible wonders: the famed gap in its rings, detailed band structures in its atmosphere, and a number of moons.

One of those worlds, TRAPPIST-1e, might be the vacation hotspot of the future.
