The Hubble Space Telescope Obtained This Image of the NGC 1898 Globular Cluster, Close to the Center of the Large Magellanic Cloud Galaxy
Wow! Just look at this stellar wealth. Countless stars in the cluster of NGC 1898 shine on the recently released photo of the Hubble Space Telescope (ESA and NASA). For years, Hubble observed the structure found in 1834 by the British astronomer John Herschel. NGC 1898 is located near the center of the Large Magellanic Cloud - a dwarf satellite galaxy of the Milky Way, distant by 160,000 light years.
Globular clusters are considered one of the oldest objects of the Universe and are listed as relics of the era of the formation of the first galaxies. Scientists have a good picture of the globular clusters of the Milky Way, but studies of objects in nearby galaxies have just begun. Observations on NGC 1898 will help determine whether an object is similar to globular clusters of the Milky Way. The Hubble Space Telescope launched into Earth orbit in April 1990. His original photos turned out to be blurred, which in 1993 had to fix the defect problem on the main mirror. From 1997-2009 completed 4 additional support missions and upgrades. In the last flight, the astronauts replaced all 6 gyroscopes supporting the orientation of the telescope. Because of the third failure, Hubble was recently transferred to safe mode.
The telescope needs three working gyros for maximum efficiency, but the backup doesn’t meet the expectations so far. NASA is confident that Hubble will return to work in the usual way. If you do not run three gyros, then use two, where the second will play the role of a backup.
