…wait until NASA and its international partners launch the James Webb Space Telescope (JWST), which will be 100 times more power than its venerable 25-year-old predecessor. More from Business Insider:
The space telescope will weigh 6.4 tons. JWST’s main mirror will be 6.5 meters (yards) in diameter, three times as large as Hubble’s.
A joint project of NASA, the European, and Canadian space agencies, JWST will carry four instruments, including cameras and spectrometers that can capture extremely faint signals.
Infra-red capability will help it observe distant celestial bodies, and its camera shutter will be able to remain open for long periods, explained Matt Greenhouse, JWST project scientist for the science instrument payload.
“The Webb will have 70 times the light-gathering capacity of Hubble. So the combination of the large size and the infra-red capabilities will allow us to observe this epic of the universe past,” he said in an interview
An official statement by NASA describes the over $8 billion telescope as a “powerful time machine with infrared vision that will peer back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the early universe.”
Indeed, it is so powerful that may even be able to detect signs of life on distant exoplanets, down to the specific composition of their atmospheres.
Moreover, unlike the Hubble Space Telescope, which circles the Earth, the JWST will be 930,000 miles (1.5 million kilometers) away, at a place called LaGrange Point. That means it will be colder and thus suffer less interference from radiation and its own infra-red light.
The heavy telescope is scheduled to launch October 2018 atop an Ariane 5 rocket, made by the European Space Agency, from French Guiana.
Given the breathtaking images Hubble has given us over the last quarter-century, to say nothing of how much it has advanced our understanding of the universe, it is exciting to imagine what something 100 times as powerful will offer us.
And if NASA can pull something like this off, albeit with help from its foreign partners, imagine what it could do with more funding and public support…
It is also encouraging to see more international cooperation in space exploration. I have noted numerous times before how the technological and financial challenges of space travel necessitate humanity pooling together all its resources and expertise. The JWST will be a strong testimony to that.
