The Hubble Telescope made its way to space on the twenty-fourth day of April 1990. The Space Shuttle Discovery initiated the launch from the Kennedy Space Centre. Kennedy Space Center is present in Florida. The Hubble Telescope derives its name from the astronomer Edwin Hubble. Edwin Hubble was born in the year 1889 in Missouri. He is well-reckoned scientists for his arguable discovery which indicates that universe is expanding. The rate at the which the universe expands today is known as the Hubble constant.
Since the Hubble Telescope mission started in the year 1990, it explored more than 1.3 million observations. It supported the publishing of more than fifteen thousand scientific papers.
Presently, the Hubble Telescope orbits the Earth with a speed of about seventeen thousand mph. This Hubble Telescope orbits the Earth in the low Earth orbit. The height at which it is orbiting corresponds to about three hundred and forty miles in altitude.
It possesses the pointing accuracy of about .007 arc seconds. It has a primary mirror of about 2.4 meters which corresponds to about seven feet and 10.5 inches. The total length of the Hubble Telescope is about 13.3 meters which correspond to about 43.5 feet. You can say the Hubble Telescope resembles a large school bus in its length.
We all know that the early galaxies are all distant. But when you observe these early galaxies from Hubble Telescope’s eye, these resemble red spots in the deep-sky images.
One such galaxy is the NGC 1277. According to the comparative research done on the relic galaxy as well as the Milky Way, the researchers concluded that the relic galaxies possess about twice the number of stars in comparison to our Milky Way.
Researcher Ignacio Trujillo adds, “The galaxy NGC 1277 gives us a unique opportunity to study a ‘primitive’ galaxy in the ‘local’ universe. We can explore such original galaxies in full detail and probe the conditions of the early universe.”
NASA is all set to launch its upcoming space telescope in the year 2019. This telescope is named as Nasa James Webb Space Telescope. The Nasa James Webb Space Telescope will assist the astronomers to detect and measure the globular cluster motions in NGC 1277.
