XRISM: Canadian scientists to get glimpse of the hot universe
Launch: Between and
Mission duration: 5 years
Mission status: In development
Many people think of space as a cold and empty place, but some structures in the universe are incredibly hot. In fact, at the centre of most galaxies lie supermassive black holes, whose surrounding regions can reach millions of degrees.
X-rays can be described as a hot, high-energy form of light that the human eye cannot see. Many kinds of astronomical objects, like massive stars, black holes, and clusters of galaxies, emit X-rays. Because Earth's atmosphere shields us from this cosmic radiation, astronomers must send observatories into space to study these exotic objects.
Led by the Japan Aerospace Exploration Agency (JAXA), the X-Ray Imaging and Spectroscopy Mission (XRISM) is a new space observatory that will take a closer look at the hot, often violent ways that galaxies form and stars burn out.
Canada's role in the mission
The XRISM observatory will feature two scientific instruments, Xtend and Resolve, which must be tested and calibrated before installation and launch. NASA has chosen to perform these tests at the Canadian Light Source, an synchrotron facility in Saskatoon, Saskatchewan, that is capable of generating X-rays.
In addition to these efforts, the Canadian Space Agency is also supporting the participation of Canadian scientists:
- Dr. Luigi Gallo, of Saint Mary's University, on the XRISM science team
- Dr. Brian McNamara, of the University of Waterloo, on the Resolve instrument team
Members of Canada's astronomy community will be able to compete for guest observer time, an exciting opportunity to conduct cutting-edge research into cosmic sources of X-rays and to shed light on the structure of our universe.
