Its exciting to imagine these stars as inter galactic seeds for the heavier elements we find on earth. They randomly get flung out from the middle of the galaxy and go supernova in a planetary nebula, causing lots of disturbance which can help kick start star formation

[stenkarasin]

Another great upload, Mr Petrov but I must say that the more of your stuff I watch, the more impressed I become at how seemingly unique our star and solar system is.

[WaterShowsProd]

I guess it would effectively transfer materials from very active regions of the galaxy to less active regions, and may possibly be how a wealth of heavy elements wound up in an area quiet enough to foster our own solar system.

I appreciate you taking the time to share all these discoveries and theories with the public. You provide a constant reminder of the fact that there is room for adventure in this universe, and plenty left to learn!

[marknovak]

Runaway black holes must be common too. Good thing spaces is vast.

[subcitizen]

Just a thought, once there's a fling event, they could in theory keep slingshotting and gaining momentum with other systems. Then the hypervelocity ones manage to encounter these interactions with black holes, central black holes. Very fun. I want one.

[witwisniewski]

Interstellar travel: Just find a "local" black hole, get a gravitational assist from it to reach a significant fraction of c, then use a distant black hole to slow back down. :)

Wonderful as always Anton. Thank you. 😁

Considering the lifetime of stars, at least the non-O, non-B types who don't live long enough, many of these stars can easily live long enough to visit several galaxies at the rate at which some are traveling. How many of the stars detected have visitors from another galaxy?

[ysx]

The Be type stars and their rings and the run-away stars seem related if you ask me. I'm no scientist but it sure seems like they could have a relation. One star goes flying and the other ends up with a ring and spins really fast. Makes sense in my pea brain! haha

Would be interesting to know study about stars in inter galactic space.

[andycordy]

I've been a regular viewer for several years, so the comment at the beginning about all stars moving at different velocities cane as something of a surprise!

I was dimply aware of the phenomenon of rogue planets and how they might become separated from their place of origin but I never imagined that there was a population of stars that bolted across the heavens at barely imaginable velocities.

When the subject of supernovae was broached as a possible explanation, I was trying to imagine the kind of explosion that could project super planetary sized objects at huge speeds without blasting them to pieces in the way that a shotgun obliterates objects in the path of its projectiles. BTW. I'd love to know more about how the power of a supernova manifests in terms of the material propelled outwards and if the propulsive force is dependent on the materials ejected or even how, in a near vacuum, an explosion actually works.

Personally, the gravitational slingshot effect seems more likely to produce the required propulsion for a large star.

[davidcombs]

Beautiful photos, and possibilities!!

[Reohz]

Anton, I hope you know that you're a star.

[Neon_White]

In a multi-star system, when one of them explodes, the other stars still keep their inertia, and can get slung away like from a spinning slingshot.

🇺🇸 AWESOME, KEEP SHINING ANTON.!. 🌞 🇺🇸

[stargazer]

O-B associations are amazing places. Extremely hot and violent... Best viewed from a respectable distance. Some good basic astronomy for the layperson here! Thx Anton.

[AnthonyMuscio]

If a type 1a supernova occurs in a multi star system since the remnant is usually no more than dispersed gas would this not reduce the point source of gravity in the system such that some stars leave, moving there orbital velocity into a somewhat strait line?

[yomogami]

another great video anton. thanks
i'm wondering do any of these stars have planets? are there smaller stars running away from home?

[LifeMaxxingOfficial]

Babe wake up Anton just dropped a new video.
