Today’s news – Washington – Arab Today
An image of a rare astronomical phenomenon taken by the Hubble Space Telescope shows explosions of blue gas from a cloud of dust. The image captures a phenomenon known as the “Herbig-Haro object”, which some scientists describe as a “blue sword”. bad. net”.
So, what do we see in this picture?
Astronomer Brad Tucker of the Australian National University explains that what you’re seeing is the birth of a star system.
“In the middle you have what we call a protostar – where gas from a previous star collapses into a new child star,” Tucker says.
The new object rotates rapidly and, as it does so, releases a stream of ionized gas – gas so hot that it has lost all of its electrons – from its north and south poles.
The gas travels through dust clouds. And as it moves away, Dr. Tucker explains, it starts spreading in the same way you would watch your breath on a cold morning.
*Why is the phenomenon considered so rare?
Although quite astonishing, it is difficult to identify these phenomena easily.
For a start, these objects only wander for 10,000 to 20,000 years.
“That sounds like a long time, but in the astronomy chart, it’s actually a short time frame for something to exist,” Dr. Tucker says.
Objects are not very bright because dust absorbs a lot of their light, so we can only see them if they are relatively close.
“You can’t see it in other galaxies – you only see it in the Milky Way,” Tucker continues.
