The James Webb Telescope Releases Its First Focused Image

This week eager astronomers got an update on the progress of the James Webb Space Telescope (JWST), which launched last December. After a long period of tweaking and alignment, all 18 mirrors of the massive orbiting scope are now in focus. 

In a briefing this week, Marshall Perrin, the Webb deputy telescope scientist, said that the team had achieved diffraction limited alignment of the telescope. “The images are focused as finely as the laws of physics allow,” he said. “This is as sharp an image as you can get from a telescope of this size.”  Although actual scientific images from the scope are still months away, the initial test images had astronomers buzzing.

Rachel Feltman, executive editor at Popular Science, joins Ira to talk about the progress on JWST, and other stories from the week in science, including plans to launch a quantum entanglement experiment to the International Space Station, an update on the COVID-19 epidemic, and a new report looking at the diagnosis of Alzheimer’s disease. They’ll also tackle the habits of spiders that hunt in packs, and the finding that a galloping gait may have started beneath the ocean’s waves. 

 

The Climate Crisis Is Driving New Home Improvements

A lot of the changes that need to happen to keep global warming under 1.5 degrees Celsius need to happen at a huge, international level. But nearly a fifth of carbon emissions in the U.S. come from our homes. Are there things we can do at home to help the climate crisis? And how effective are individual actions?

Threshold is a podcast telling stories about our changing environment. And as their fourth season explores what it will take for the world to keep global warming under the crucial 1.5 benchmark, reporter Nick Mott explores what individuals can do to decarbonize their homes.

Mott talks to Ira Flatow about his own home improvement project, in a preview of Threshold’s next episode.

 

From Succulents To Bugs: Exploring Wildlife Crime

The world of science is surprisingly ripe with true crime stories.

Consider case number one: Deep in South Africa’s Northern Cape, a rare and tiny succulent grows: the Conophytum. Demand for succulents skyrocketed during the pandemic, as more and more people got into the plant keeping hobby. But these succulents only grow in very specific conditions, and poachers will go to great lengths to nab them. The story is the subject of a recent investigation published in National Geographic.

Or case two: It’s 2018, and a theft has occurred at the Philadelphia Insectarium, a bug museum and education center. In a daring daylight raid, thousands of creatures were taken from the insectarium—right under the nose of the CEO. No one has ever been charged with a crime.

This bizarre big story quickly made the rounds of local and national news, which left out the most interesting details, including a surprise ending. The new documentary series “Bug Out” takes us through the twists and turns of this story, from retracing the events of the day of the heist, to a deep look at the illegal international insect trade. The four episodes of “Bug Out” are available to watch now on IMDB TV and Prime Video.

 

Joining Ira to chat about these wildlife true crime stories are Dina Fine Maron, senior wildlife crime reporter for National Geographic and Ben Feldman, director and executive producer of “Bug Out.”
