NASA | The Mysterious Holes in the Atmosphere on Venus

The video explores Venus's lack of a magnetic field and its interaction with the solar wind, leading to atmospheric stripping and the formation of a comet-like tail. The Pioneer Venus Orbiter and Venus Express missions provided insights into mysterious ionospheric phenomena and magnetic structures on Venus's nightside. These structures, observed throughout the solar cycle, suggest complex interactions between solar wind and Venus's atmosphere. The video also compares Venus's magnetic properties with Earth's, highlighting the importance of understanding planetary interactions with stars.

Explain the two possible explanations for the behavior of magnetic field lines on Venus.

How does the lack of oceans on Venus relate to its interaction with the star?
