A new map for a birthplace of stars — the Orion A molecular cloud


[Shuo Kong speaking] This Orion-A molecular cloud is the closest massive star forming region. This molecular cloud is
about 400 parsecs from us, which is about twelve hundred
light years. So what makes our survey
different is, we combine data from two very different
telescopes. We’re looking at the cloud, the gas cloud,
at different velocities. So we don’t just have an image
of the cloud, but we have an image of the gas at every
different velocity. So we can see where the gas is in space
and we can also see how the gas is moving. By studying this cloud we can
understand how massive stars form and we can understand how
they impact their surrounding environments. That really helps
us move forward in terms of understanding the Milky Way
evolution. Star formation is important
to understand because without stars you don’t get planets,
without planets of course, we wouldn’t be here on the
earth. So to understand star formation is to really
understand where we came from.
