Given what we know about Herbig-Haro (HH) objects, we can confirm that they are born from the collision between a jet from a star and clouds of interstellar matter.
<h3>What are Herbig-Haro (HH) objects?</h3>- To put it simply, a Herbig-Haro (HH) object is what we observe as a bright spot in distant space. Upon closer observation we can observe that these giant bright patches are not lone objects, but in fact immense groups of interstellar matter.
- The formation of one of these interstellar groups requires an <em><u>immense amount of energy</u></em>. This energy come from the speed at which the materials that form these objects collide.
- As stated in the question, the jet released from a star in the process of being born <em><u>smashes into a giant cloud of </u></em><em><u>dust </u></em><em><u>and </u></em><em><u>interstellar material </u></em><em><u>to form the </u></em><em><u>Herbig</u></em><em><u>-</u></em><em><u>Haro </u></em><em><u>(HH) </u></em><em><u>objects</u></em>.
- This collision happens at hundreds of km/s. To put it into perspective, it would be roughly 500,000 miles per hour.
Therefore, we can confirm that option b, which states, "<em>where a jet from a </em><em>star </em><em>in the process of being born </em><em>collides </em><em>with (and lights up) a nearby cloud of </em><em>interstellar matter</em>", is the correct choice for the question pertaining to Herbig-Haro (HH) objects.
