According to the paper laying out the research behind the discovery, "TOI-1846b is a super-Earth-sized planet, with a radius of approximately 1.8R⊕, placing it within the intriguing radius valley area ...

Hundreds of distant planets may be far larger than scientists once believed. New research reveals that many exoplanets found ...

The exploration and study of exoplanets have advanced significantly in recent years, leading scientists to reconsider how ...

Astronomers want direct images of exoplanets. They may need 'quantum-level' tech to get them Victoria Corless Thu, May 22, 2025 at 9:00 AM UTC 7 min read ...

Scientists cast doubt on signs of alien life on K2-18b Since then, at least three different studies have largely dismissed the notion that any compelling evidence has been found to yet suggest ...

Space Exoplanet found in odd perpendicular orbit to brown dwarf star pair It is rare to find brown dwarf stars orbiting in pairs, and this pair has an even more unusual exoplanet companion By ...

Astronomers have located a rare exoplanet on the edge of the Milky Way. The exoplanet, a gas giant named AT2021uey b, orbits a low-mass star and is located about 3,200 light-years away from Earth ...

These observations link the disk population directly to the exoplanet population." Finally, our planetary system lacks a super-Earth, the creation of which seems favored by small protoplanetary disks.

So in some sense, alien worlds were not first discovered in the 1990s or even the 1980s. It took nearly a century to fully understand it, but the first evidence for exoplanets was found in 1917.

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
