The Event Horizon Telescope is tackling one of the largest cosmological challenges ever undertaken: Take an image of the supermassive black hole at the center of our galaxy, using a telescope the size of the Earth. 
Now, the Event Horizon team has announced they have big news to share about those efforts. On Wednesday April 10th, it’s anticipated they will show a photo of the event horizon. Before they do, we wanted to share this 2016 conversation with Event Horizon project director Shep Doeleman and black hole expert Priya Natarajan, in which they discuss how you image an object as dark and elusive as a black hole.

Plastics are everywhere, in packaging, clothing, and even our bodies. Could they be made less integral to manufacturing and more recyclable?

Why Is Solving The Plastic Problem So Hard?

Superfund sites contain extreme pollution. Flooding—made worse by climate change—could carry their toxic contaminants into surrounding areas.

What Worsening Floods Mean For Superfund Sites

An explosion of research is painting a clearer picture of how climate change is affecting mental health across the globe. Also, a citizen science project aims to find species that have gone unnoticed by sampling the waters of hundreds of lakes worldwide for environmental DNA.
