Stronger monsoon drove ancient Indus civilization into the hills

Roughly 4,000 years ago, the Indus River Valley was home to the advanced and thriving Harappa culture. But by 1800 B.C., the civilization’s sophisticated cities along the river, which drains into the Arabian Sea on the coast of what is now Pakistan, were abandoned for smaller villages in the Himalayan foothills. A new study suggests that widespread changes in the Indian winter monsoon may have resulted in flooding that forced people to resettle farther from the Indus.

When Earth first formed, the oceans of water we know today were nowhere in sight. The long-standing consensus about where our planet’s water came from posits that it was not present during Earth’s formation and that it was later brought by chondritic materials like meteorites, asteroids and comets. But new research suggests some also came from the solar nebula — the gas and dust left over from the formation of the sun that created the planets.

Art joins science in coral communication

Scientists are not alone in their quest to observe and understand how coral reefs change through time. Artists and researchers have been creating stunning paintings, movies and even soundscapes to examine how reefs are responding to environmental pressures. Art has the power to engage viewers in scientific inquiry when they least expect it, reaching new audiences and facilitating public awareness.

Piecing together the big picture of coral reef health

To better understand what’s happening to the world’s reefs, a team of researchers launched the 100 Island Challenge, a plan to survey 100 reefs twice each in five years using traditional methods combined with advanced imaging technology. Learning how reefs grow and change over time will help local populations better manage and conserve the fragile yet vital ecosystems.

Voyager 2 pierces the heliopause, enters interstellar space

On Nov. 5, 2018, Voyager 2 became the second spacecraft to enter interstellar space, as it passed through the heliosphere’s outer limit, known as the heliopause, NASA announced at the American Geophysical Union (AGU) fall meeting in Washington, D.C., on Monday. The spacecraft’s twin, Voyager 1, made history as the first man-made object to depart the heliosphere in 2012. Reaching interstellar space is an extraordinary feat for spacecraft that have been traveling for more than 41 years.
