X-ray astronomy – Amateur X-ray astronomy

Collectively, amateur astronomers observe a variety of celestial objects and phenomena sometimes with equipment that they build themselves. The United States Air Force Academy (USAFA) is the home of the US’s only undergraduate satellite program, and has and continues to develop the FalconLaunch sounding rockets. In addition to any direct amateur efforts to put X-ray [...]

Sounding rocket X-ray astronomy – Introduction

X-ray Astronomy

Sounding rocket X-ray astronomy involves using a sounding rocket to carry an X-ray detector to high altitudes. The first evidence of X-rays from the Sun and of an astronomical X-ray source from the Milky Way (MW), other than the Sun, was detected by a sounding rocket. These rockets have contributed significantly to our understanding of [...]

X-ray astronomy – X-ray astronomy detectors

X-ray Astronomy

X-ray astronomy detectors have been designed and configured primarily for energy and occasionally for wave-length detection using a variety of techniques usually limited to the technology of the time. X-ray detectors collect individual X-rays (photons of X-ray electromagnetic radiation) including the number of photons collected (intensity), the energy (0.12 to 120 keV) of the photons [...]

X-ray astronomy – Stellar X-ray astronomy

X-ray Astronomy

Stellar X-ray astronomy is said to have started on April 5, 1974, with the detection of X-rays from Capella. A rocket flight on that date briefly calibrated its attitude control system when a star sensor pointed the payload axis at Capella (α Aur). During this period, X-rays in the range 0.2-1.6 keV were detected by [...]

X-ray astronomy – Single X-ray stars

X-ray Astronomy

In addition to the Sun there are many unary stars or star systems throughout the galaxy that emit X-rays. β Hydri (G2 IV) is a normal single, post main-sequence subgiant star, ”T”eff = 5800 K. It exhibits coronal X-ray fluxes. The benefit of studying single stars is that it allows measurements free of any effects [...]

X-ray astronomy – History of X-ray astronomy

X-ray Astronomy

In 1927, E.O. Hulburt of the US Naval Research Laboratory and associates Gregory Breit and Merle A. Tuve of the Carnegie Institution of Washington explored the possibility of equipping Robert H. Goddard’s rockets to explore the upper atmosphere. “Two years later, he proposed an experimental program in which a rocket might be instrumented to explore [...]

X-ray astronomy – X-ray astronomy satellites

X-ray Astronomy

X-ray astronomy satellites study X-ray emissions from celestial objects. Satellites, which can detect and transmit data about the X-ray emissions are deployed as part of branch of space science known as X-ray astronomy. Satellites are needed because X-radiation is absorbed by the Earth’s atmosphere, so instruments to detect X-rays must be taken to high altitude [...]

Solar X-ray astronomy – Introduction

Solar X-ray astronomy is a branch of X-ray astronomy which focuses on understanding the origin of X-ray emission from the Sun. Most of our current knowledge of the Sun comes from observing it in the visual portion of the electromagnetic spectrum. However, when observed with appropriate instruments in the X-radiation portion of this spectrum the [...]

Amateur X-ray astronomy – X-ray source files

With so many successful X-ray astronomy satellites over the last forty years gathering data on upwards of half a million astronomical X-ray sources, there simply is not sufficient time nor skilled people to process and correlate this information with visible sources, among others. Here is an opportunity for amateur astronomers to contribute significantly. Consider the [...]
