Astronomers, employing Hubble Space Telescope as a fragment detector, trace cosmic rays surging in Earth’s geomagnetic sphere

The Hubble Space Telescope needs slight or no opening. For more than 30 years, the telescope has put up at the lead of astronomical research. Although its visually spectacular pictures have functioned as an epitome of awe and encouragement.

Energetic charged fragments, or cosmic rays, occupy every spot of the solar system. A near-constant movement of galactic fragments begins from supernova remnants (and the stellar residues at their foundations). The Sun also casts energetic fragments, primarily protons, through solar flares and coronal mass expulsions.

These cosmic rays jiggle and push their way across the solar system under the impact of the magnetized solar breeze.

Characteristics of charged fragments when they end up at Earth include:

  • Endanger astronauts
  • Disrupt satellites
  • Affect atmospheric chemistry

Cosmic rays are every astronomer’s horrendous. Nor the ground neither space telescopes are resistant to the torrent of the energetic fragments. When a fragment journeys through a camera, it gives a sharp and vivid trace on the resultant picture. Astrophysicists try to eliminate this contamination from their statistics.

But now researchers have shown that one person’s trash is another’s a treasure.


The findings offer essential evidence of ideas with positive results. The cosmic ray properties from Hubble statistics match those found by the PAMELA experiment. Which is an obsolete fragment detector in low-Earth orbit. The crew also saw in their information the South Atlantic Anomaly, the legendary dip in the Earth’s geomagnetic sphere. And they noted the likely reaction of cosmic rays to the solar cycle.

Claudio Corti (the University of Hawai ‘i at Manoa), who was not a part of the research, was pleasingly amazed by the effort. “There is constantly an attraction in a superior understanding of the geomagnetic sphere. Along with the impact it has on the fragment radioactivity for astronauts and electronics on the satellites,” he says. The statistics might prove valuable in order to comprehend cosmic ray populaces in the solar system.

The evaluation so far has just scraped the surface. The crew is exploring ahead to releasing the full capacity of the statistics. This is in order to better comprehend the relation among galactic cosmic rays, the Sun, and Earth’s environment. “One of our interests is to consider if we can find ingenious secular variations in the geomagnetic sphere,” Deustua says. “We also intend to make analogies with geophysical viewpoints.”

Hubble’s continuous examination of cosmic rays throughout a quarter of a century effectively complements other cosmic ray detectors. “From one single-point measurement, it is difficult to get data on the international space environment,” Corti says. “The more things you have, the nicer it is.”
