Hubblertávcs

Hubblertávcs, also known as the Hubble Space Telescope, is a space-based observatory launched into low Earth orbit in 1990. It is named after the American astronomer Edwin Hubble. The telescope is a collaboration between NASA and the European Space Agency (ESA). Hubblertávcs is designed to observe the universe in visible, ultraviolet, and near-infrared light. It has provided some of the most detailed and stunning images of the cosmos, including the Hubble Deep Field, which revealed thousands of galaxies in a small patch of sky.

The telescope has a primary mirror that is 2.4 meters in diameter, which is larger than any ground-based telescope at the time of its launch. This large mirror allows Hubblertávcs to capture high-resolution images of distant objects. The telescope is equipped with a variety of scientific instruments, including cameras, spectrographs, and fine guidance sensors. These instruments allow astronomers to study a wide range of astronomical phenomena, from nearby planets to the most distant galaxies.

One of the most significant contributions of Hubblertávcs to astronomy is its role in determining the rate of expansion of the universe, known as the Hubble constant. This measurement has helped to refine our understanding of the age and size of the universe. The telescope has also been used to study the formation and evolution of galaxies, the properties of black holes, and the nature of dark matter and dark energy.

Despite its many achievements, Hubblertávcs has faced challenges, including the need for several servicing missions to repair and upgrade its instruments. The most famous of these was the first servicing mission in 1993, which corrected the telescope's flawed primary mirror. The telescope is expected to continue operating until at least 2025, when it will be replaced by the James Webb Space Telescope.
