The Hubble Space Telescope (HST), among other advanced instruments (both space-based and ground-based using techniques like adaptive optics), was instrumental in capturing the first detailed images of the surface of a star other than our Sun. Betelgeuse, a red supergiant star in the constellation Orion, was one of the first stars whose surface was resolved, due to its large apparent size despite its distance. HST's observations in the UV range in the mid-1990s provided early insights into its atmosphere and features.
Hubble space telescope has for the first time detailed image of surface of distant star. Name of the star is:

Orbits of the satellites could be disturbed. 7. Shortwave radio communication of the aircraft flying over polar regions could be interrupted. Which of the statements given above are correct?
- Power grids could be damaged Rapid changes in the Earth's magnetic field can induce currents in long conductors like power lines, potentially overloading and damaging transformers, leading to blackouts. 4. Intense aurorae could occur over much of the Earth Increased particle influx into the atmosphere leads to more widespread and intense aurora displays, visible at lower latitudes than usual. 6. Orbits of the satellites could be disturbed Heating and expansion of the upper atmosphere increase atmospheric drag on satellites in low Earth orbit, causing them to lose altitude. 7. Shortwave radio communication of the aircraft flying over polar regions could be interrupted Solar storms disrupt the ionosphere, which is crucial for reflecting shortwave radio signals over long distances, particularly affecting communications in polar regions where magnetic field lines channel particles. 70.
