But the James Webb Space Telescope's predecessor, the Hubble Space Telescope, is showing us why it shouldn't be forgotten. .

NASA and ESA, who co-manage Hubble, have just released (opens in new tab) a new spectacular image of globular cluster NGC 6638, a star cluster in the constellation Sagittarius.

Prior to Hubble, it was nearly impossible to discern the individual stars in a globular cluster, which is a dense collection of ancient stars numbering in the tens of thousands to millions.

By comparison, Webb is about 1 million miles (1.5 million kilometers) from Earth, far beyond though it primarily operates in the infrared spectrum, while Hubble operates in the visible-light spectrum.).

(Or at least they could when the space shuttle flew.) But Hubble is located at a point in which the atmosphere is so thin that it doesn't obscure the observatory's view of the stars.

As such, Hubble has been instrumental in globular cluster research, and it continues to make new discoveries regularly. !

While Hubble is already more than 30 years old, the telescope still has quite a bit of life left in it, and scientists will continue to use it in conjunction with the James Webb telescope to answer the biggest questions about the cosmos.
