New 3D maps of the Milky Way confirm our galaxy is warped

It turns out our Milky Way galaxy isn't the flat spiral disk we thought it was before -- dark matter or collisions with other galaxies could have twisted it out of shape.

Scientists have designed reusable nano-sized reactors — called nanocoils — that can trigger microplastic breakdown. The work could someday be applied to wastewater, cutting off the flow of microplastics before they are flushed into the environment. Photo by REUTERS/Eric Gaillard

This new nanotech could help clean up Earth’s microplastics

Chemists have adapted emerging technology -- called nanocoils -- to dissolve microplastics and turn the pollution into food for algae.

Katie Bouman ‘hardly knew what a black hole was.’ Her algorithm helped us see one

Imaging scientist Katie Bouman chats with the PBS NewsHour about how she crafted an algorithm that constructed the first ever photo of a black hole.

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

Why the northern and southern lights don’t always look identical

By Vicky Stein

On a clear night, people near the poles might see colorful light wafting across the sky. New research could explain why these auroras don't look the same to everyone .
