The space X-ray picture may soon get a little clearer.
A Black Brant IX suborbital rocket topped with the Diffuse X-rays from the Local galaxy (DXL) experiment launched from NASA's Wallops Flight Facility on Wallops Island, Virginia at midnight EST (0500 GMT) on Sunday (Jan. 9).
DXL was designed to gather data about "soft" X-rays, which aren't as energetic as the ones doctors use to image bones but can cause disturbances high in Earth's atmosphere that interfere with radio communications and GPS navigation.
The origin and nature of soft X-rays remain somewhat mysterious.

"Very low-energy diffuse X-rays from space are believed to come from two sources," Massimiliano Galeazzi, the principal investigator for the DXL mission from the University of Miami, said in a NASA statement.
"The first source is located outside our solar system and is generated by remnants of multiple supernovae explosions forming what is now called the Local Hot Bubble region of our galaxy," Galeazzi said. "The second source is within the solar system and is generated by the solar wind charge exchange. DXL seeks to gain a better understanding of the nature and characteristics of these sources."
The DXL payload reached a maximum altitude of 166 miles (267 kilometers) during Sunday's flight and gathered good data, NASA reported in an update to the same statement.
The launch was the fourth in a series of DXL suborbital missions. The first, in 2012, showed that just 40% of the soft X-ray background originates in our solar system. That means that the Local Hot Bubble is the primary source, NASA officials said in the statement.
Sunday's launch was visible to skywatchers under clear skies throughout the mid-Atlantic region, a number of whom posted their views of it on Twitter.
