Seneca Falls Convention 1848 – first US women’s rights convention

At the Wesleyan Chapel in Seneca Falls, N.Y., a women’s rights convention was the first ever held in the United States. Almost over 200 women attended this convention. The convention was organized by Lucretia Mott and Elizabeth Cady Stanton. Mott and Stanton were two abolitionists who met at the 1840 World Anti-Slavery Convention in London over a cup of tea. As women, Mott and Stanton were not allowed on the convention floor. The anger and disappointment these women felt was the driving force that helped them start the women’s suffrage movement in the United States. At the convention, Stanton read a treatise she had wrote called the Declaration of Sentiments and Grievances, which was heavily based on the Declaration of Independence. It called women to recognize their rights as US citizens. Its purpose was "to discuss the social, civil, and religious condition and rights of women.” Organized by women for women, many consider the Seneca Falls Convention to be the event that triggered and solidified the women's rights movement in America. Historians and other scholars agree that the leaders of the Seneca Falls Convention played a significant role in shaping the first wave of feminism in the United States and starting the fight for women’s suffrage.  (https://votesforwomennhd.weebly.com, and https://www.biography.com/)

Saturn – one of its moons is bigger than Mercury

Like fellow gas giant Jupiter, Saturn is a massive ball of mostly hydrogen and helium. Surrounding by 53 confirmed and nine provisional moons, Saturn is home to some of the most fascinating landscapes in our solar system. Like Jupiter, Saturn is mostly made of hydrogen and helium, the same two main components that make up the sun. Saturn rotates in the same direction as the Earth, which is west to east, but it does this far faster than Earth, spinning around once in just 10.7 hours. While the days on Saturn are short, the years are long. The sixth planet from the sun takes 29 Earth years, or 10,756 Earth days, to complete one revolution around the sun. As a gas giant, Saturn doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Saturn, it wouldn't be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet would crush, melt and vaporize a metal spacecraft trying to fly through the planet. Like Jupiter, Saturn is made mostly of hydrogen and helium. At Saturn's center is a dense core of rock, ice, water, and other compounds made solid by the intense pressure and heat. It is enveloped by liquid metallic hydrogen, inside a layer of liquid hydrogen -- similar to Jupiter's core but considerably smaller. It's hard to imagine, but Saturn is the only planet in our solar system that is less dense than water. The giant gas planet could float in a bathtub -- if such a colossal thing existed. Saturn's largest satellite, Titan, is a bit bigger than the planet Mercury. Titan is the second-largest moon in the solar system; only Jupiter's moon Ganymede is bigger.
