The Hubble telescope transmitted an image of the globular cluster NGC 6544. informs NASA.
This cluster of gravitationally closely bound stars lies 8,000 light-years from Earth and, like all globular clusters, is a densely populated region with tens of thousands of stars.
The published image was synthesized from observations made with two Hubble Advanced Camera for Surveys and Wide Field Camera 3 instruments. Pulsars are astronomical objects with rhythmically variable radiation that “blink”. According to modern concepts, at their center is a super-dense rotating neutron star with a strong magnetic field inclined to the axis of rotation. Narrow rays strike through the poles of such a star, in radio or some other range, and the pulsar “flashes” as they pass over Earth.
The purpose of the second observation was to search for visible equivalents of objects detected in the X-ray range. Both will help astronomers determine how NGC 6544 evolved.
