Short answers, pulled from the story.
The Local Interstellar Cloud spans roughly 30 light-years across and overlaps with the region astronomers call the solar neighborhood. It remains unknown whether our star sits fully inside this cloud or exists in the transition zone where it meets the neighboring G-Cloud complex.
Scientists estimate the Solar System entered this cloud within the past 10,000 years. A recent analysis suggests the Sun will completely exit the Local Interstellar Cloud in no more than 1,900 years.
Measurements show only 0.3 atoms per cubic centimeter floating in space within the Local Interstellar Cloud. This density is less than the average for interstellar matter in the Milky Way but six times greater than the hot gas filling the surrounding Local Bubble.
The cloud flows outward from the Scorpius Centaurus association a stellar region forming new stars roughly perpendicular to the Sun's own direction. This movement creates a dynamic environment where the solar neighborhood constantly shifts relative to its neighbors.
Voyager 2 data collected in 2009 revealed magnetic strength values ranging from 370 to 550 picoteslas. Previous estimates had placed these figures much lower between 180 and 250 picoteslas.
