In ultraviolet images, these regions appear darker because they lack the hot, glowing gases usually confined by magnetic fields, as the plasma escapes outward instead. The solar wind escaping from ...

These areas appear darker in ultraviolet images because the hot, glowing gases typically trapped within the magnetic fields are no longer contained, instead streaming outward into space.

This artist's impression shows Jupiter and its moon Europa using actual Jupiter and Europa images in visible light. The Hubble ultraviolet images showing the faint emission from the water vapour ...

The experiment should eventually lead to direct imaging of the planet orbiting that star. IMAGER makes a four color ultraviolet images in order study the creation and destruction of dust in the galaxy ...

Appearing as a dark void in ultraviolet images, it signals a region where solar wind is escaping at speeds exceeding 1.8 million mph toward Earth. Positioned directly toward Earth, this coronal ...
