NASA’s James Webb Space Telescope

[Mic Drop]

NASA’s James Webb Space Telescope is often called a “time machine.”

On Tuesday, the $10 billion telescope earned that nickname after NASA released five images of the universe as it appeared ~13.5 billion years ago—or 300 million years after the Big Bang. The pictures deliver the deepest, sharpest, and most telling look yet into how galaxies merge, where stars are formed, the composition of space objects, and much more.

Compare and contrast: The Webb is 100 times faster and more powerful than its predecessor, the Hubble Space Telescope—and that’s because of tech advancements over the past three decades, Stefanie Milam, a deputy project scientist for planetary science on the James Webb Space Telescope team, told us. 

• Hubble was primarily a visible-light telescope, whereas Webb uses infrared spectrometers and cameras, plus large mirrors, allowing it to deliver higher-resolution images than ever before. 
• The telescope’s multi-shutter array allows it to collect information on up to 100 different galaxies at once, compared to Hubble’s one-at-a-time operation.
