Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that ...
About 50 light-years from Earth, a gas giant about half the mass of Jupiter orbits a sunlike star. The discovery of Pegasi 51 b ushered in a new era of exoplanet research.
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 ...
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 ...
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 ...
"The complexity of the exo-Neptunian landscape provides offers a unique window onto the processes involved in the formation and evolution of planetary systems." Astronomers have launched a new program ...
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 ...
Artistic illustration of the internal structure of a lava planet in a cold state, showing a day‑side magma ocean overlain by a mineral atmosphere. The arrows indicate the direction of heat transport ...
Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that ...
"Water on planets is much more limited than previously believed." Sub-Neptune planets, often billed as possible "water worlds," may be more desert than deep sea, according to a new study. For years, ...
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 ...
