Study explores magnetosheath jets on Mars

Magnetosheath jets on Earth are plasma entities that have a higher dynamic pressure surrounding the plasma and can cause waves that transfer energy within such environments. Such jets also exist beyond Earth in the magnetosheath ...

Radio emission detected from the Vela X-1 bow shock

An international team of astronomers has conducted radio observations of a bow shock in the X-ray binary Vela X-1 using MeerKAT telescope. The observational campaign resulted in the detection of radio emission from this source. ...

The mystery of heavy elements in galactic cosmic rays

Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving ...

Spitzer spots a starry region bursting with bubbles

This infrared image from NASA's Spitzer Space Telescope shows a cloud of gas and dust full of bubbles, which are inflated by wind and radiation from young, massive stars. Each bubble is filled with hundreds to thousands of ...

Rosetta witnesses birth of baby bow shock around comet

A new study reveals that, contrary to first impressions, Rosetta did detect signs of an infant bow shock at the comet it explored for two years – the first ever seen forming anywhere in the solar system.

Study shows how Earth slows the solar wind to a gentle breeze

As Earth orbits the sun at supersonic speed, it cuts a path through the solar wind. This fast stream of charged particles, or plasma, launched from the sun's outer layers would bombard Earth's atmosphere if not for the protection ...
