A quartet of small, rocky exoplanets likely circle Barnard's Star, around 6 billion light-years from Earth, putting them in ...

A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation of ...

Considered a solitary star for its lack of stellar companions, Barnard's Star is notoriously lonely—signs of any exoplanets ...

making it a significant step forward as astronomers search for Earth-mass planets around sun-like stars, Basant said. “A lot of what we do can be incremental, and it’s sometimes hard to see ...

"Unlike an Earth-like planet, where atmospheric noise and telescope limitations make it difficult to detect biosignatures, Hycean planets offer a much clearer signal," said UCR astrobiologist ...

Each new planet, even if uninhabitable, helps us better understand the vast diversity of worlds beyond our solar system and brings us closer to uncovering Earth-like planets.

In the end, the researchers determined that exoplanets whose radii are between 4 to 16 Earth-radii have eccentricities four times greater than exoplanets whose radii are between 0.5 to 4 ... giant ...

The planets orbit the sun continuously in the solar system, so at times, they slowly catch up to one another. Because they travel along the same path, or ecliptic, as they pass Earth ...

rather than gas planets like Jupiter, the scientists said. That will be difficult to pin down with certainty; the angle we see them from Earth means we can't watch them cross in front of their ...
