A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky es range in size from dwarfs with just a few hundred million (10 8) stars to giants with one hundred trillion (10 14) stars, each orbiting its galaxy's center.
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in and remains in operation. It was not the first space telescope but it is one of the largest and most versatile, well known both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and.

THE SOLAR ARRAY-INDUCED DISTURBANCE OF THE HUBBLE SPACE TELESCOPE POINTING SYSTEM INTRODUCTION The Hubble Space Telescope (HST) 1 was deployed from the remote manipulator system of the space shuttle Discovery in a nmi.

Hubble Space Telescope solar array change-out, mission anomalies and returned flight by: The investigation of the vibrational disturbances of the Hubble Space Telescope that were discovered soon after deployment in orbit is described in detail.
It was found that the disturbances were particularly evident during orbital day-night crossings, and that the magnitudes of the disturbances were considerably larger than the design jitter by: 7. The solar array-induced disturbance of the Hubble Space Telescope pointing system.
By C. Foster The control system was successfully modified to attenuate the disturbances to tolerable levels pending mechanical and thermal redesign of the solar arrays. The new arrays were installed during the first space telescope servicing mission and.

Thermal Performance of the Hubble Space Telescope (HST) Solar Array-3 During the Disturbance Verification Test (DVT) The Hubble Space Telescope (HST) is one of NASA's most productive astronomical observatories.
Launched inthe HST continues to gather scientific data to help scientists around the world discover amazing wonders of the universe. For example, the Hubble Space Telescope (HST) have been observed to have vibrations induced by thermally driven bending of the solar arrays when the solar array structure reacts to temperature changes occurring as the spacecraft passes from shadow to sunlight.
This ‘thermally induced vibration’ causes performance degradation of the power. The solar radiation input and the surface emitting radiation are included in the heat transfer equations.
Furthermore, the influence of the rigid body motion and the deformation on the radiant absorption are also considered with the self-shadowing.

[C L Foster; United States. National Aeronautics and Space Administration.;]. The power for Hubble's scientific discoveries comes from solar cells.
Designing and constructing Hubble's first two sets of solar cell arrays constituted a huge technological achievement for the European Space Agency and European industry. After an in-orbit life of more than 8 years, this example of pioneering space technology was this morning (European time) replaced by new, more powerful arrays.

About 30% more powerful than those they replaced, and should be more durable. Along with this, they are only 50% the size reducing residual atmospheric drag, and improving stability. The telescope has had a major impact on every area of astronomy, from the solar system to objects at the edge of the universe.
Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system.

Both classical and H(infinity) control design methodologies are employed for such a control problem with a non-colocated actuator and sensor pair. This paper successfully demonstrates the effectiveness of a dipole concept for precision line. Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed `Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year.
