Scientists have come a step closer to identifying the mysterious origins of the “slow” solar wind, using data collected during the Solar Orbiter spacecraft’s first close journey to the sun.

Solar wind, which can travel at hundreds of kilometers per second, has fascinated scientists for years, and new research published in Nature Astronomy, is finally shedding light on how it forms.

Solar wind describes the continuous outflow of charged plasma particles from the sun into space—with wind traveling at over 500km per second known as ‘fast’ and under 500km per second described as “slow.”

When this wind hits the Earth’s atmosphere it can result in the stunning aurora we know as the Northern Lights...

The Earth’s liquid molten outer core, composed mostly of iron and nickel, exerts an electromagnetic field extending from the north and south pole that protects the planet from harmful solar particle radiation.

Fluctuations in the strength of Earth’s magnetic field—caused by daily changes in solar wind structure and intermittent solar storms—can impact the use of geomagnetic field models which are essential for navigation in satellites, plan...

A new analysis of data collected on Venus more than 30 years ago suggests the planet may currently be volcanically active.

A research group from Italy led by David Sulcanese of the Università d’Annunzio in Pescara, Italy, has used data from a radar mapping of Venus’s surface taken in the early 1990s to search for volcanic lava flow, finding it in two regions.

The discovery suggests that volcanic activity may be currently active and more widespread than was previously thought, support...

Using observations by NASA’s TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make it a candidate well-suited for further study using NASA’s James Webb Space Telescope.

TESS stares at a large swath of the sky for about a month at a time, tracking the brightness changes of tens of thousands of stars at intervals ranging...
