Smart Starlight: The Hubble Space Telescope sees a star as a blob (simulated, left), but MROI will be able to see features on the surface. Star spots (simulated, right) can indicate a star’s age because they are caused by magnetic activity that ebbs as a star gets older.From Popular Mechanics:
One mountaintop telescope may not be able to do it alone, but a new array of telescopes under construction in the New Mexico desert will offer never-before-seen cosmic vistas.
On a 10,500-ft.-high mountaintop above the New Mexico desert, construction has begun on a $45 million array of telescopes that will reveal enlightening details of stars and black holes. The Magdalena Ridge Observatory Interferometer (MROI), named for its mountaintop perch, will capture distant light in as many as 10 movable 1.4-meter (about 4 1/2-ft.) telescopes. When these light beams are combined, they will create images that will be hundreds of times sharper than those of the Hubble Space Telescope, according to Chethan Parameswariah, the lead electronics engineer on the project. MROI’s ability to capture images of natural processes that before had only been measured indirectly will provide insight into the formation of planets, the life cycle of stars and patterns of radioactive cosmic dust. The first two telescopes will arrive in 2010; researchers hope to start observations by 2012.
