A team of astronomers, including a researcher from Ohio State, located a planet orbiting two stars that resembles the planet Tatooine from the movie series “Star Wars.” Using a technique known as the ...

Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in “Star Wars.” The planet, Kepler-16b, is about 245 light ...

As the first successful technique used to detect exoplanets orbiting distant stars, the radial velocity method aims to detect a periodic Doppler shift in a stellar spectrum due to the star's motion ...

When our sun reaches the end of its life, it will expand to 100 times its current size, enveloping the Earth. Many planets in other solar systems face a similar doom as their host stars grow old. But ...

The first exoplanet discovery in 1995 around a Sun-like star challenged the then-prevailing model of planetary system formation based solely on our solar system, revealing the existence of massive ...

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s brightness when a planet passes in front of it, and the radial velocity ...

Using the combined power of three U.S observatories, astronomers discovered a planet three times the mass of Jupiter that orbits around its star on an unusual, oval-shaped path, according to a study ...
