NASA’s Webb Telescope Will Investigate Cosmic Jets From Young Stars
As an interstellar gas cloud contracts to form a star, it spins more rapidly, just as a twirling ice skater does when she draws in her arms. The only way for the gas to continue moving inward is to lose some of the spin. NASA's James Webb Space Telescope will be able to penetrate those clouds to see exactly how that happens.
In a process that’s still not fully understood, magnetic fields funnel some of the swirling material into twin jets that shoot outward in opposite directions. These jets travel at speeds of hundreds of miles per second and spread across light-years of space.
