How Webb Illuminates Stars’ Cloudy Origins

In the space between stars, dark clouds of gas, dust, and ice mingle in a chemical laboratory unlike any on Earth. Ewine van Dishoeck, an astronomer who studies molecules in space and who helped develop an instrument aboard NASA’s James Webb Space Telescope, explains how Webb is revealing new details about the formation of stars and planets. This research could help unlock a key question about Earth: how did our planet end up with water and the ingredients for life?

What Webb Is Teaching Us About Our Solar System

NASA’s James Webb Space Telescope is hard at work answering our biggest questions about the birth of our universe and faraway galaxies. But some astronomers are pointing its powerful eyes much closer to home. In this episode, Caltech astronomer Katherine de Kleer explains how Webb is rewriting our understanding of objects within our solar system–from space rocks in the asteroid belt to the icy and volcanic moons of Jupiter and Saturn.

Why Webb's Earliest Galaxies Are Blowing Scientists' Minds

With the James Webb Space Telescope, we are seeing the early universe like never before. Webb produces beautiful images and detailed scientific data that leave astronomers in awe. In this episode, Mic Bagley, a NASA scientist on the Webb team, guides us through new discoveries made possible by Webb. Mic tells the story of a remarkable galaxy discovered in the early days of Webb’s science mission and explains why Webb is teaching us “everything” about how galaxies form and evolve.

Cosmic Dawn with Nobel Laureate John Mather

The James Webb Space Telescope is doing something astronomers dreamed about for decades: peering into our universe’s early past, a period known as cosmic dawn. A new NASA documentary—also called Cosmic Dawn—chronicles the inside story of Webb’s design, construction, and launch. John Mather, who won the 2006 Nobel Prize for Physics, proposed the telescope and led its science team for decades. In this interview, Mather talks about his life, his research, and the pre-dawn phone call telling him he had won the Nobel Prize. Find more at nasa.gov/cosmicdawn

Webb's Exoplanet Research Sounds Like Sci-Fi—But It's Real

Some exoplanets—like a gas giant with rain made of glass and 5,000-mile-per-hour winds—sound like worlds dreamed up by a science fiction writer. But they’re real. From light-years away, scientists can uncover details about planets orbiting distant stars and even ask whether some exoplanets could support life. Néstor Espinoza, an astronomer at the Space Telescope Science Institute, explains how NASA’s James Webb Space Telescope is revealing new details about exoplanets, especially rocky worlds like Earth.

How Lying In Bed For 60 Days Helps Astronauts

In space, microgravity changes the body. Body fluids shift from the legs toward the head, the back of our eyes flatten, we lose muscle strength, our bones lose some of their density, and even the amount of blood pumped by the heart with each beat drops. To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, scientists are asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle. This research approach tricks the body into reacting very similarly to how it would if a person was aboard the International Space Station for a longer-term mission. Join Andreas Joshi, a volunteer who agreed to be part of this bedrest work, and two NASA scientists leading the study. They’re investigating different ways to combat space-based muscle loss and improve astronauts’ sense of balance by, among other things, teaching volunteers like Joshi to play video games with their feet.
