Astrobites provides a journey to the outer solar system to learn about the latest models describing the influence of the hypothesized Planet Nine.

Compilation of 12 images of the sun taken during a solar eclipse, so the extended solar corona and streams of solar wind are visible.

A detailed set of images of the eclipsed Sun has helped scientists to identify the source of streams of high-energy particles from our star.

Signs of Extreme Survivor Stars

A recent study considers what sort of stars could live in the extreme environments surrounding supermassive black holes.

Ground-based measurements of Ryugu’s surface are helping to complete the picture of this nearby, rocky body while we wait for sample analysis.

An artist's impression of a rocky exoplanet is seen in the centre of the image, illuminated from the right by a large star. The planet is dark, almost black in colour, however small cracks cover its surface revealing glowing red underneath, as if the planet is made of magma that has cooled in places. The planet's atmosphere appears to be being blasted away from the planet by the star.

Astrobites reports on whether interactions between magma and a planetary atmosphere can create a water dominated super-Earth.

Scientists have long puzzled over slow and regular variations in the brightness of many evolved giant stars. Have we now found an explanation?

Where We Might Find Life

As we develop the tools to search for life’s signatures in exoplanet atmospheres, where should we look first to maximize our chances? Astrobites reports.
