Any parent of newborns know just how powerful even small things are.
The same is true in space, where baby stars in a section of a nebula, or gas cloud, create a series a powerful shockwaves visible in a new Hubble Space Telescope image.
Hubble was on the hunt for how young stars influence their environment, and this image of Herbig-Haro (HH) 45 gives abundant evidence. (To go all “Inception” for a moment, this object is embedded in a nebula called NGC 1977, which itself is part of the larger “Running Man” set of three nebulas. So you can see this is a rather complex neighborhood in which the stars are growing up.)
In HH45, what we see here is a rare manifestation of a nebula that happens after a newborn star spews hot gas, NASA noted. This activity “collides with the gas and dust around it at hundreds of miles per second, creating bright shock waves,” agency personnel wrote in a statement.
The Hubble image shows two sets of ionized gases glowing as the collision strips away charged electrons from their atoms. Blue shows ionized oxygen, while purple indicates ionized magnesium. “Researchers were particularly interested in these elements because they can be used to identify shocks and ionization fronts,” NASA said.
Hubble is coming back online from a synchronization glitch that occurred on Oct. 23 and sent its science instruments into safe mode. But while Hubble personnel get its instruments back to normal, there’s lots of work available from previous investigations.
