NASA-Funded Sounding Rocket Solves One Cosmic Mystery, Reveals Another

In the last century, humans realized that space is filled with types of light we can’t see – from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of the universe. Some of this invisible light that fills space takes the form of X-rays, the source of which has been hotly contended over the past few decades.

It wasn’t until the flight of the DXL sounding rocket, short for Diffuse X-ray emission from the Local galaxy, that scientists had concrete answers about the X-rays’ sources. In a new study, published Sept. 10, 2016, in the Astrophysical Journal, DXL’s data confirms some of our ideas about where these X-rays come from, in turn strengthening our understanding of our solar neighborhood’s early history. But it also reveals a new mystery – an entire group of X-rays that don’t come from any known source.
