Exhibit

Today marks the launch of a new project – both physically and virtually. We are so happy to announce that "Here, There, and Everywhere" (known by the acronym of HTE) has officially debuted.

You may have heard this question, or asked it yourself: why bother studying things that are millions or billions of miles away in space? HTE, among other things, is a project that addresses that question.

Looking back on the more than twelve years of science from NASA’s Chandra X-ray Observatory and trying to predict what it will find in the future, one thing is certain: we can expect the unexpected.

This blog series will look at both some of the anticipated findings from the past dozen or so years, plus some of the unexpected results so far from the Chandra mission. Today, we look at discoveries involving our Solar System.

Expected and Detected:
X-ray emission was detected from the atmospheres of planets and comets. The X-rays are produced when solar X-rays and high-speed particles flowing away from the Sun hit these atmospheres. The observed X-radiation provides information on the outer atmospheres of these objects that is difficult to obtain with other telescopes.
