NASA approves construction of new infrared space telescope

Engineers are preparing to build a telescope that will find the nearest star-like objects and the brightest galaxies. NASA has approved the start of construction on a new mission called the Wide-field Infrared Survey Explorer, which will scan the entire sky in infrared light.

WISE will spend seven months collecting data.

Such extensive sky coverage means the mission will find and catalogue all sorts of celestial eccentrics. These may include brown dwarfs, or failed stars, that are closer to Earth than Proxima Centauri, the nearest star other than our sun. Brown dwarfs are balls of gas that begin life like stars but lack the mass to ignite their internal fires and light up like normal stars. They do, however, produce warm infrared glows that Wise will be able to see.
