From candles to ladders: how astronomers measure very large distances in the universe
How do we know the universe is expanding? Your high school trigonometry is involved in the process.
Ever wondered how scientists know the distance to planets, stars, galaxies? Or even better, how to measure the universe’s size and its expansion? Well, they certainly don’t have a giant ruler, but they have other tools including “candles” and “ladders”.

The easiest way to measure things far from Earth is called parallax and was discovered by ancient scientists not just the Greeks (who are usually responsible for discovering things), but several other ancient societies with knowledge of astronomy.

Dorothy Height, who died in 2010, spoke openly about the sexism she experienced within the civil rights movement, challenging this by working with other women to establish women s political organizations such as the National Women s Political Caucus. Height engaged white women in the movement, highlighting the particular struggles faced by African American women who experience both sexism and racism. The National Women s Political Caucus still exists today, showing the extent and importance of Dorothy Height s political activism.
