NASA to launch 300-megapixel space telescope around 2025
NASA is designing a space telescope which would be able to image a sky area 100 times larger than the Hubble Space Telescope. Scheduled to launch in mid-2020s, the 300-megapixel Wide Field Infrared Survey Telescope (WFIRST) would study how the universe expanded over time. It would help learn more about dark energy, thought to make up 68% of the universe.
