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 ...

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 ...

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

To store heat for days, weeks, or months, you need to trap the energy in the bonds of a molecule that can later release heat ...

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting closer to their stars than Mercury, and rocky worlds much larger than Earth ...

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 ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Twenty four states are now considering legislation to allow small, plug-in solar power systems that connect directly into a wall socket. By Claire Brown As the Trump administration stymies hundreds of ...

Astronomers have captured some of the most detailed images of debris discs—rings of leftover dust, gas, and rocks that circle a star—from fully formed, "teenage" planetary systems. And those images, ...
