Its strong stellar wind precedes it, compressing and heating the dusty interstellar material and shaping the curved shock front.

Indeed, Cheng expects that the energy of the shock front at the galactic centre is nearly 100 times greater than that created by a supernova explosion.

确实，Cheng预计银河中心激震前沿的能量将近是超新星爆发产生的能量的一百倍。

This interstellar "bullet," traveling over three million miles per hour (5 million km), is just catching up with the shock front, which has been slowed by plowing into interstellar material.

这个蓝色的“子弹”每小时飞行500万公里(300万英里)，恰好能赶上激震前沿，此时冲击波因为星际物质的阻挡已经减速。

The particles get a little kick in energy every time they cross the shock front, and eventually they get accelerated to these massive energies that we detect here at Earth.

Munster had made a powerful start and it was no shock when they edged in front with a simple Paul Warwick penalty after Daryl Gibson sneaked offside in his own danger zone.

Of course it will be a shock for him to be playing in different colours and in front of different fans after 13 years at Highbury.
