The large spiral galaxy called NGC 6872 has two elongated arms stretching to the upper right and lower left. Just to the upper left of NGC 6872 appears another smaller spiral galaxy. These two galaxies, each of which likely has a supermassive black hole at
the center, are being drawn toward one another. X-rays from NASA’s Chandra X-ray Observatory, represented sonically by a wind-like tone, show multimillion-degree gas that permeates the galaxies. Meanwhile Hubble Space Telescope data reveal the galaxy’s spiral arms and background stars as low drone sounds, soft plucks and cymbals. 
cymbals.

We don’t yet know what dark matter is, yet it makes up 85% of all the matter in the universe. The Roman Space Telescope will aim to unravel the mystery. With a field of view 100 times wider than the Hubble Space Telescope’s, Roman will study in near-infrared light the atmospheres of planets orbiting other stars, making other exoplanet discoveries along the way. The mission is named after Dr. Nancy Grace Roman, NASA’s first chief of astronomy and advocate for the development of the Hubble Space Telescope.

The idea of an asteroid from outer space crashing into Earth has captured the imaginations of science fiction directors for decades. But here at NASA, we take potentially hazardous near-Earth objects seriously. We have a planetary defense office that plans for every scenario—we’ve even practiced nudging an asteroid off course with spacecraft. But there are tens of thousands of objects in near-Earth space, and the first step in protecting against potential impacts is spotting, tracking and managing every single one of them. Learn how NASA does just that from Joe Masiero, a scientist on the asteroid survey mission NEOWISE. Then, join friend of the show Latif Nasser, co-host of the podcast Radiolab, to untangle the mystery of a strange space rock that’s not quite a moon but not quite a normal asteroid, either.

An Asteroid by Any Other Name With Special Guest Latif Nasser

The Sun is the ultimate source of life in our solar system, a radiant powerhouse that bathes Earth in the energy necessary for everything from photosynthesis to weather patterns. Its warmth and light sustain us. However, the Sun’s influence isn't always benign. Its solar wind—a stream of charged particles—can disrupt our technology, causing communications blackouts and GPS glitches. In this episode, Dr. Joseph Westlake, director of NASA’s Heliophysics Division, joins us to shed light on why the Sun is such a critical focus for space research.
