Hubble Telescope Essay

Researcher at both Harvard and Yale University have discovered that older star emit a pulsating effect similar to a heartbeat. They have also been able to measure, for the first time, the ways an older, red, pulsating can affect the light their encompassing galaxy. The discovery was made with the use of a unique series of images of galaxy M87, in the constellation Virgo, taken with the Hubble Space Telescope over a period of three months in 2006.

The effect on light from pulsation from older stars on Galaxy M87 were detected with use of specific images taken during a three month period in 2006 by the Hubble Space Telescope. The Hubble Telescope is a space telescope that was launched into Earth’s lower orbit in 1990. Hubble’s orbit outside of Earth’s atmosphere’s distortion allows it to take exceptionally high-resolution images with little to no background light. The Hubble Telescope is operated by the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and by the Space Telescope Science Institute (STSCI). 1

They tended to think galaxy as steady and static beacons of the sky but they are instead shimmering/flickering, cause by all the pulsating stars in the galaxies. Throughout their lives, stars experience momentous changes. They become brighter and surge in size, absorbing and destroying anything within its distance. Towards the end of their lifetime, they begin to quiver and pulsate, increasing and decreasing their illumination every few hundred days. Until now, no person had ever studied the way pulsating starts effect the light coming from distant galaxies, where the light of the pulsating stars is mixed with many more stars that have a more constant illumination. After sung the images from the Hubble telescope to confirm the change in brightness from Galaxy M87, they concluded that stars in that galaxy pulsate once, nearly every 270
