British researchers utilized which observatory to discover that the magnetic field of the Sun exceeds previous estimates by a factor of 10 __________?
Show answer Hide answer
Answer: B. One metre Solar Telescope
Explanation
British solar physicists used this specific optical telescope to capture high-resolution magnetic data. Measurements obtained from the instrument revealed solar magnetic field strengths far exceeding older estimates. The telescope facility allowed researchers to analyze sunspot magnetic structures with unprecedented precision. Solar telescopes are specialized astronomical instruments designed to observe the sun without optical damage. The Sun possesses a complex magnetic dynamo that drives solar flares and coronal mass ejections. Observatories located on high mountain peaks benefit from reduced atmospheric distortion during observations.
Understanding solar magnetism is crucial for protecting satellite communication networks from space weather storms. Advanced telescope observations continually refine our theoretical models of stellar physics and magnetism. Accurate solar measurements help scientists predict geomagnetic disturbances that impact power grids on Earth. Option A refers to a different historical solar telescope used in early astrophysical investigations. Option C is a fictional space telescope name that does not exist in astronomical literature. Option D names a famous space telescope that primarily observes distant galaxies rather than the sun.
