When evaluating possible planets out of the thousands out there, explained Prof. Bean, scientists look for liquid water as a main guiding principle. “All life on Earth needs liquid water, no matter ...

In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely hospitable to life. And as technology advances, astronomers only expect to ...

A low-density, puffy planet orbiting relatively far from a young star in a nearly perpendicular orbit. What's going on? If you think you've met the wildest exoplanet yet, you haven't learned about TOI ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger ...

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...

Detecting exoplanets at all is difficult—they typically emit much less than 1% of a host star's brightness. Eclipse mapping requires measuring small fractions of that total as a planet circles behind ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...

Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one orbiting Earth could potentially form. Using data from NASA’s James ...

In our solar system, Earth is one of but eight planets – nine if you really want to count Pluto – and the only one remotely hospitable to life. But look beyond our sun's gravitational pull into the ...
