The Milky Way（银河系）is a large spiral galaxy（螺旋形星系）.For example，the Sun is just one of many stars in the Milky Way.
The galaxy is so vast that it holds countless mysteries and no one knows how big it is.It is made up of billions of stars，gas，and dust（尘埃）.The Milky Way has a spiral structure，with a central bulge（鼓起）and several spiral arms.In these arms，new stars are being born all the time.The spiral arms wind outwards from the center.
Among the many wonders of the Milky Way，some are mysterious celestial bodies（神秘的天体）.Black holes，for example，are objects with such strong gravitational（重力的）pull that nothing can escape from them.They can swallow（吞噬）everything on their way.Neutron（中子）stars are also interesting.They have very strong magical fields.
Scientists are exploring the Milky Way to discover its secrets.They use powerful telescopes to see the stars and study them.
根据材料内容选择最佳答案。
41.What does the Milky Way look like？ ______

Nine Earths side by side would almost go across Saturn's diameter.That doesn't include Saturn's rings.Saturn is the sixth planet from our Sun and orbits（沿轨道绕行）at a distance of about 1.4 billion kilometers from the Sun.
Saturn has beautiful rings.Of all the planets in the solar system，Saturn's rings are the biggest and brightest.According to scientists，however，these rings will disappear one day.
How did Saturn get its rings in the first place？Scientists have no certain answer.But there's a popular theory（理论）：Saturn had at least 60 moons（卫星）.Some comets（彗星）or small planets ran into Saturn's moons.And this created a large number of ice and rock pieces.These pieces were different in size.Some were as small as grains（颗粒）of sand，but others were as large as houses.
These pieces began to travel around Saturn.Saturn's gravity（引力）pulled them towards it.At the same time，the speed of their orbit tried to throw them into space.Over time，these pieces of ice and rock formed（形成）rings around Saturn.
