Any time you see something, with your eyes or with an instrument, it is because light from the object reaches you. This light takes a while to reach you; if the object is at a distance of 30 centimeters, it will take a nanosecond; if it comes from the star Rigil Kentaurus, it will take over 4 years, and if it comes from the galaxy M31, it will take 2-3 million years. That means that if we see the light from a distant star, it may already be dead (from a certain point of view - see the definition of simultaneity in the Theory of Relativity).
The Hubble Space Telescope captures and transmits images of the light emitted by stars, providing valuable information about their age, composition, and behavior. It does not have the capability to directly observe living stars or detect signs of life on them. Its primary function is to gather and transmit images and data from distant celestial objects for scientific research and analysis.

Because the earths atmosphere tends to block and stir up some of the light from stars and so by having a telescope not in the atmosphere no light is blocked and there are no air currents or density differences so you can see more than a telescope on the ground.

The Hubble Space Telescope primarily uses ultraviolet, visible, and near-infrared light to capture images of celestial objects. These wavelengths are ideal for observing astronomical phenomena such as stars, planets, and galaxies.

The Hubble Space Telescope can see objects billions of light-years away, allowing it to observe galaxies, stars, and other celestial objects located far beyond our own Milky Way galaxy. It has contributed significantly to our understanding of the universe's vastness and complexity.

No invasion of privacy. The telescope aims at the stars in space and not at objects on Earth.
The Hubble Space Telescope has made numerous groundbreaking discoveries, including determining the rate of expansion of the universe, identifying the presence of supermassive black holes at the centers of galaxies, and capturing images of distant galaxies and nebulae. It has also played a key role in our understanding of dark matter, dark energy, and the formation of galaxies.
Some instruments used in studying stars include telescopes, spectrographs to analyze the light from stars, photometers to measure the brightness of stars, and interferometers to combine light from multiple telescopes for higher resolution imaging. Telescopes can be ground-based or space-based, like the Hubble Space Telescope.

So that man can and see and study the stars in away not possible from earth.
to try to find the beginning of the universe..to study the stars...
The Hubble Space Telescope helps us by providing high-quality images of distant celestial objects, which helps astronomers study the universe in more detail. It also helps us understand the origins of the universe, track the movement of planets and other phenomena, and discover new celestial objects.
The Hubble Space Telescope, launched in 1990, uses a large hyperbolic mirror to take highly detailed astronomical photographs. Hubble's orbit outside Earth's atmosphere allows it to take extremely sharp images without distortion or light pollution.
