Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

It comes down to the speed at which these objects were moving during their formation, and the strength with which their ...

A new paper in Monthly Notices of the Royal Astronomical Society argues the simplest answer may work: contact binaries like Arrokoth can form directly during the gravitational collapse of a dense ...

Abstract: The concept of access to solar energy is an abstraction that must be generalized to urban fabric within cities in presence of modern, high-rise buildings that are increasing daily, with two ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after much of the ...

Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how ...

In late winter, the zodiacal light is visible in the evening in the Northern Hemisphere (false dusk) and in the pre-dawn ...

Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses.

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

A team of astronomers has identified a four-planet system orbiting the red dwarf star LHS 1903 that defies conventional expectations about how planets arrange themselves around their host stars. The ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form. Reading time 3 minutes Astronomers have discovered a star system that’s out of ...

Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific expectations – and suggests these faraway worlds formed in a manner never seen ...
