So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't been for lack of trying. According to a new paper by Thomas Winterhalder of the European Southern ...
Searching for exomoons—moons that orbit around another planet—was one of the most exciting capabilities expected of the James Webb Space Telescope (JWST) when it launched in late 2021. So, after four years of operation, why ...
Have scientists finally confirmed the existence of the first exomoon? This is what a study released on the preprint server arXiv, and accepted for publication in Astronomy & Astrophysics, hopes to address. A large international ...
At a young age, we're told how the sun warms Earth and makes life possible. That idea sticks with most of us for life. But when we want to understand things more thoroughly and we dig more deeply, we learn that Earth has ...
There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must exist. Moons are common ...
Exoplanets aren't the only objects floating around other stars—they likely have comets and asteroids as well. Even some of the exoplanets themselves will have "exomoons," at least according to our current understanding of ...
We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon in our solar system ...
People always want to know what will happen to Earth when the sun eventually swells up as a red giant. For one thing, the expanding sun will turn the inner planets into cinders. It will almost certainly spell the end of life ...
How would detecting methane help astronomers identify if exoplanets, or even exomoons, have life as we know it, or even as we don't know it? This is what a recent study published in The Astronomical Journal hopes to address ...
Astronomers may have discovered a scrawny star bolting through the middle of our galaxy with a planet in tow. If confirmed, the pair sets a new record for the fastest-moving exoplanet system, nearly double our solar system's ...
