Breezing through the space environment of Barnard's Star b

The closest exoplanet to us, if we include only single stars like the Sun, is the planet around Barnard's Star, Barnard's Star-b ("BSb"). (The planet Promixa Centauri-b is closer, but Proxima Cen is part of a triple-star ...

ALMA observes the formation sites of solar-system-like planets

Researchers have spotted the formation sites of planets around a young star resembling the sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in the solar system, ...

How the seeds of planets take shape

In theoretical research that could explain everything from planet formation to outflows from stars, to even the settling of volcanic ash, Caltech researchers have discovered a new mechanism to explain how the act of dust ...

Planet formation starts before star reaches maturity

A European team of astronomers has discovered that dust particles around a star already coagulate before the star is fully grown. Dust particle growth is the first step in the formation of planets. The researchers from the ...

First interstellar immigrant discovered in the solar system

A new study has discovered the first known permanent immigrant to our Solar System. The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system. The work ...

How many of earth's moons crashed back into the planet?

For decades, scientists have pondered how Earth acquired its only satellite, the Moon. Whereas some have argued that it formed from material lost by Earth due to centrifugal force, or was captured by Earth's gravity, the ...

New study shows what interstellar visitor 'Oumuamua can teach us

The first interstellar object ever seen in our solar system, named 'Oumuamua, is giving scientists a fresh perspective on the development of planetary systems. A new study by a team including astrophysicists at NASA's Goddard ...
