I was going to mention the ring bearer too :-) What I found super interesting in this video is that I'm old enough (43 years) to remember that when I was a teenager, I was explained that the way the solar system is (I mean the order of the planets according to their sizes) was the "norm". My point is not to underline that astronomers were wrong. My point is that not knowing anything else than our own solar system implicated that the only acceptable choice was to think our solar system was nothing special, thus the explanations about its formation had to fit this constraint. I hope one day we can have tools to observe not only planets, but moons too in other systems. Because by our actual knowledge, the couple of our Earth and Moon is already not the "norm" in our own solar system (of course I mean in respect of their relative masses). But it may be even more rare... Having a rough estimation of the probabilities of having a similar solar system, plus a similar couple Earth/Moon, may transform strongly the Drake equation. We may be the winners to the GalaxyMillions...or even the winners of the SuperClusterMillions :-) Gwendal PS: sorry for the poor english, I'm French.

Dr. Becky, since you're here, could you please ELI5 again why the energy exchange happens as it does? Obviously each of the 2 interacting stars' masses doesn't change, so why the change of speed?

M44 is probably the only object in the sky that I learned about through finding it myself and having to look up what it was. So it has a special place in my heart! Super excited to learn more about it; now it's also the only place in the sky I can point to and know there's another planet there. :D

I am suddenly LEARNING so much thanks to Dr Becky!

Left everything aside to watch Dr. Becky explaining this star cluster.

Your videos are always my favorite astrophysics entertainment and education channel. Currently at the pharmacy waiting for an Rx and this is my favorite way to wait! Keep up the excellent work Dr Becky.

These are all such great videos! Thank you guys!

More videos please!!! Can't get enough and need more about anything.

Love Dr. Becky!

M44 is a great object. Wonderful to observe with binos or a small telescope. This is a great story about the cluster. Makes the whole thing even better.

ohhh sweet! a few day ago there was this really clear night sky and I recently got really interested in stargazing and looking for clear and obvious formations in the sky and I saw this pretty cluster pretty clearly. took a bit to find out it was an actual cluster and even a messier object. definitely cool that you guys made a video about it now!

I wonder if the Saturn-Jupiter resonance, keeping Jupiter from migrating into the inner solar system, (and them existing in the first place soaking up comets & asteroids) is one of the precondition for life to start/continue on Earth...

Subscribed👍 These are very informative videos to this backyard, amateur astronomer working my way through the Messier Catalog. It is absolutely fantastic to observe an object after viewing your video on it or returning to an object with more information gained from your previous videos with follow up research of my own. Thanks from Northern California👍👍💫🔭😁

Great video. Well explained and very interesting.

thanks deepsky for all the great vids and for introducing us all to dr. becky. thumbs up :)

I can also see it being called the "beehive" because of the sort of triangular pattern of the large blue stars, kinda reminds me of a beehive. And maybe that in combination with the other stars being like a swarm around it.

Great explanation visuals on how the planet is detected.

I appreciate the bubbling enthusiasm over such an anodyne topic.

Great video!

Just came across this Channel and I'm glad I did! Beautiful explanation of the structure and properties of deep Sky objects. Especially for someone new to astrophysics and a newb amateur astronomer(bought my first telescope, a $40 50mm refractor from Walmart, about 8 months ago and upgraded to a used Orion 12" dobsonian about 2 months ago). I guess you can say I'm a proto-nerd.. lol

Really enjoying your videos... very interesting...

I was just looking for a DSV on M44! M44 will be 6* away from the Eclipsed Moon on January 20th!

Thank You! Love you! Fantastic!

Wonderful!

I'm hoping to return to M44 (observing 😅) this evening and feel the experience will be more fulfilling knowing what Ive learned in this video. Many thanks for posting

What are the theories about the star with the "noisy" diagram? Is it difficult to observe for some reason, or could it mean that it has several bodies influencing it?

M44 is also known as Praesepe - "The Manger". I only mention it because I find it interesting that the Welsh word for manger is "preseb".

What are the implications for life sustaining planets and the drake equation? Would this migration disrupt their formation?

I think M45,M42 and M31 is also visible to naked eye?🤔🤔🤔🤔

Can we detect multiple planets from a star's wobble, or do we run into the three-body problem?

pr0201b and pro0211b are they in m44 or different galaxy ?

What would happen to smaller planets that formed closer to the star as the more massive planets migrated inward?

Can someone explain why the Kinetic energy is conserved?...I was thinking taking 2 stars as a system we can take total ext force (here gravity) as 0 (I think here we have to neglet the gravity effect from other surrounding stars) so tot energy is conserved. Now since Potential energy here is 0 (or is it?) we are saying KE is conserved. Am I thinking right?

I remember seeing something about Jupiter being in a lower orbit before stabilizing in the current orbit. Was that fake news?

The odds of stars colliding outside of dense environments like the cores of galaxies, globular clusters or the super star clusters they form from are so unthinkably low that it likely hasn't happened within the observable Universe because space is big.

Yes, the spectral lines of different elements will move due to doppleshift, so from that you can even measure the speed.

The observer's motion can easily be substracted by subtracting the average for all stars in the cluster or (apart from some constant factor that we don't care about anyway) because we know the observer's speed quite precisely. Even if you don't do that, the effects can still be distinguished by periodicity: The observer's motion will have exactly two periods, 365 days and the duration of Hubble's orbit around earth (or 24 hours if you use a telescope on the ground). Any other period will be related to the star.

If the mass of our sun is 99.8 percent of the mass of our entire solar system, how can a planet with even the mass of Jupiter cause our sun to warble?

@quantumgemini

4 жыл бұрын

I guess this warble would be very tiny and measured over 12 years and you were leading up to the possibility of a very large planet close to its star? However, have any planetary formation models shown it possible for a planet that large to form that close to a star?

I guess I should have watched the entire video since you explained the plausibility of large planets migrating towards the star it's orbiting. I think I should find information that explains a greater variety of how a solar system and variations of planets are formed.
