Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

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 ...

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 ...

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 ...

In a groundbreaking development, astronomers have identified potential biosignatures on an exoplanet, a discovery that could suggest the presence of extraterrestrial life. This article delves into the ...

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

In principle, discovering new exoplanets is pretty easy. Simply measure the brightness of a star over time, and when a planet passes in front of the star, the brightness will dim slightly. The more ...

After marking the 30th anniversary of the discovery of the first exoplanet around a sun-like star, we now look forward to what the next 30 years might offer. With the number of exoplanets having ...

"There's one we haven't found — a planet just like ours. At least, not yet." It might sound hard to believe, but NASA's exoplanet count just reached 6,000 — and that's with only about 30 years of ...
