Our Milky Way bristles with giant molecular clouds birthing stars. Based on what we see here, astronomers assume that the process of star creation also goes on similarly in other galaxies. It makes sense since their stars have to form somehow. Now, thanks to JWST, astronomers have spotted baby stellar objects in a galaxy 2.7 million light-years away. That’s millions of light-years more distant than any previous observations of newly forming stars have reached.
The targets of JWST’s observations are “young stellar objects” (YSOs) in the Triangulum Galaxy (M33). Astronomers used the telescope’s mid-infrared imager (MIRI) to study one section of one of M33’s spiral arms in the hunt for YSOs. They found 793 of these baby stars, hidden inside massive clouds of gas and dust. That’s an important discovery, signaling that the processes of star birth we know so well in our galaxy occur as we expect them to in others.
About Young Stellar Objects
To put this discovery into some kind of context, let’s take a look at young stellar objects in a bit more detail. Generally speaking, these are simply stars in the earliest phases of their evolution. Starbirth begins when materials in a giant molecular cloud start to “clump together” gravitationally. The densest part of the clump gets denser, temperatures rise, and eventually, it starts to glow. Young stellar objects can be protostars still sweeping up mass from their giant molecular clouds. They aren’t quite stars yet—that is, they haven’t ignited fusion in their cores. That won’t happen for maybe half a billion years (more or less, depending on mass).

Thanks for the link to the article by Alan Stern about the upcoming intense period of observations planned for New Horizons, ** and ** for plans to operate for an extended period as the spacecraft leaves the Solar System.
