Some of the planets in our Solar System are gigantic. But what if they got even bigger? Let’s go up the planetary size chart ...

As scientists delve deeper into a star system with seven rocky worlds, the prospect of one being a habitable planet seems to be quickly fading. Researchers who used the James Webb Space Telescope, a ...

Is our Milky Way galaxy home to other planets the size of Earth? Are Earth-sized planets common or rare? NASA scientists seeking answers to those questions recently revealed their discovery. “We went ...

In a recent paper, Harvard researchers found that raindrops are remarkably similar across different planetary environments, even planets as drastically different as Earth and Jupiter. Understanding ...

TRAPPIST-1e, an Earth-sized world in the system’s habitable zone, is drawing scientific attention as researchers hunt for signs of an atmosphere—and potentially life-supporting conditions. Early James ...

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

A giant planet the size of Saturn orbiting a sun-like star has potentially been identified in our nearest neighbouring stellar system, Alpha Centauri. At just four light years from Earth, Alpha ...

A team led by UdeM researchers confirms a fifth potentially habitable planet around L 98-59, a red dwarf 35 light-years away. A team led by the Trottier Institute for Research on Exoplanets (IREx) at ...

A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...

Researchers have found a candidate for the hypothetical Planet Nine, which could be an undiscovered giant planet way out in our solar system. However, as with all ninth planet research, the new ...
