Birthing a new space telescope takes a long time and a lot of money and inspiration. Astronomers first began pestering NASA for the successor to the Hubble Space Telescope even before that telescope was launched into orbit in 1990. Back then they thought it could cost less than $1 billion and be ready in the first decade of the 21st century.

Astronomers Find The Oldest, Most Distant Galaxy to Date

Since time immemorial, philosophers and scholars have contemplated the beginning of time and even tried to determine when all things began. It s only been in the age of modern astronomy that we ve come close to answering that question with a fair degree of certainty.
According to the most widely-accepted cosmological models, the Universe began with the Bang Bang roughly 13.8 billion years ago.
Even so, astronomers are still uncertain about what the early Universe looked like since this period coincided with the cosmic Dark Ages . Therefore, astronomers keep pushing the limits of their instruments to see when the earliest galaxies formed.
