The Hubble Space Telescope has dazzled us for years with its detailed images of the universe. The Wide Field Infrared Survey Telescope will expand its view, giving us the largest picture of the universe ever seen.
Picture the universe
The Hubble Space Telescope opened our eyes to the wonders of the Universe. From fluorescent nebulas to explosive galaxies, phenomena that had before been theorized and understood on paper came to live with vibrancy and detail few could have ever dreamed of. Thanks to the work of Dr. Nancy Roman, the “Mother of Hubble,” who was instrumental in the telescope’s development, astronomical research was propelled into the future. The Wide Field Infrared Survey Telescope (WFIRST) will expand this view. Scheduled to launch in the mid-2020′, it will provide the largest picture of the universe that has ever been seen with the same depth and clarity as Hubble.
While WFIRST will be an equally sensitive counterpart to the Hubble Space Telescope, its 300-megapixel instrument will image an area 100 times larger than Hubble was capable of.
Poster v. Wallpaper
To get an idea of just how much more we will be able to see with this new technology, David Spergel, co-chair of the WFIRST science working group and the Charles A. Young professor of astronomy at Princeton University stated that “A picture from Hubble is a nice poster on the wall, while a WFIRST image will cover the entire wall of your house.”
Technological developments like this have the power to not only inspire us with beautiful imagery, they have the ability to support and prompt research. Earlier this year, scientists discovered astounding evidence of gravitational waves using the Laser Interferometer Gravitational-Wave Observatory (LIGO).
Both technological advances that are novel, and those that are improved versions of older concepts, give us the ability to better understand the cosmos. What’s more, our ability to comprehend the great mysteries of the universe is only as good as the raw information that we have about it — and, of course, our ability to interpret it. Building instruments that are able to collect more of that information, and in even greater detail, gives scientists a remarkable power to push the boundaries of knowledge and understanding.
