M99 - Spiral Galaxy and its mystery nova - Deep Sky Videos

[@mechfeeney]

PTF was recently replaced with a 576megapixel camera called the Zwicky Transient Facility (16x 6K ccds mosaic array) on the 48” Schmidt telescope at Palomar. It is currently discovering 500K-1M transients per night. You should do a video on this! Also, 2021 for LSST commissioning is a pretty big stretch. If you ever make it to Palomar, I’ll give you a tour of ZTF.

A fracking goldmine is this series. Amateur astrophotographer now wanting to adjust my own imaging schedule. So much to image and maybe a chance to get lucky like this!

[@kevinhanley3023]

Thanks Dr. Gray.

[@iampracticingpiano]

Once you complete the Messier catalogue, please move to objects in the NGC! I love these videos and rewatch often. Thank you!

[@phoule76]

I have a soft spot for the Sears catalogue, myself.

[@CaptainOfGames]

We have all these pictures of other galaxies. Now think about this, how many pictures are there of _our_ galaxy, taken by civilizations in other galaxies? Do they make similar videos, describing the features of the Milky Way? Wondering weather one of the billions of stars in it have a civilization like theirs?

[@scottanderson8167]

CaptainOfGames think of all the naked selfies out there

[@FTLNewsFeed]

We live in a pretty unremarkable galaxy, so probably not -- they're all probably looking at M99 and the M99ians are getting a little miffed at being spied at.

[@davidmayhew8083]

Why do galaxies form spirals? They're so big one would think gravity would be too weak. Is the massive black hole at the center turning on an axis pulling the whole thing in one direction? Also, why do galaxies and solar systems function in a plane? Why don't the planet's all have eccentric orbits. And why are our solar system moons so varied??

[@colinp2238]

We are in theage now of reclassifying all objects because of the improvement of the instruments and the new discoveries being made. If you like it is the modern equivqlent to Galileo rewriting the structure of the Solar System except now it extends out into the observable Universe.

[@cush6827]

Is there a video for Messier 94 ?

[@jajwarehouse1]

Where would we be able to access the data feed from the new scope when it goes live?

[@alan2here]

You kind of want with the images: 1 - normalise(abs(A - B))

How do astronomers judge the speed of galaxies, objects etc when everything is relative? Is it as simple as that their speed is in relation to earth?

[@MrTommy4000]

Thanks for boosting my faith in mankind.

[@BattleBunny1979]

yay more content to this channel!

[@DerrangedGadgeteer]

Maybe a Nicoll-Dyson beam? Would that have a characteristic spectrum?

[@alansilverman8500]

You're mistaken, it's not perfectly face-on; it's at somewhat of an angle which is what's causing it's asymmetric appearance.

[@raulferri3842]

Very very interesting videos on all objects. Truly a great job I hope to receive new videos with particularity on many objects present in them to have even a partial part of a particular study in each Messier object. Thanks anyway it's a great job.1724

Things that go bump in the night, and an explosion of data.

[@custardthepipecat6584]

[@cerverg]

My guess is merge between 2 stars

[@GoldSrc_]

Come on, why did you add an audible sound to the explosions? You should have used a lower frequency sound instead, something that would have been felt instead of heard.

[@XEinstein]

Well, I was listening via my Beyerdynamic DT770's and was actually amazed with how low frequency those explosions actually sounded.

[@brucebrucestofiston5554]

Dr Gray and Dr Becky on the same day.

[@JoeDeglman]

This is a transient object M99. What causes a nova or supernova is that a star has entered a stream of electric flow with a higher voltage than it was in. The star tries to dissipate the additional energy into the surrounding medium by increasing its surface area and spreads out it to the surroundings. Many stars have changed positions on the HR diagram. This could be a star that is undergoing binary fission into two stars with lower luminosity to spread its surface area to adjust to the increased voltage input.

[@peterribolli8300]

Interesting, I was wondering if your cohort has decifered the meanings behind " Newgrange, knoth, Gobeklitepe, Druid knowledge of the moon cycle etc. I'm just curious if you are expanding on ancestral knowledge/memory. Apologies if I sound irrelevant:)

[@danepatterson8107]

Why do we place so much certainty on measurements of change when our relative time span of measurement (i.e., start time to stop time) is so miniscule? We're doing measurements that aren't even spanning a human lifetime. Isn't that a kind of hubris because we haven't been measuring the cosmos reliably for even 100 years? How is this not false pride in functionally useless data for the congregation of man?

Data is data, how you feel about it is your problem.

Machine learning might be the solution to handle the massive flow of data of modern instruments. That or citizen science.

[@albertperson4013]

Well, you had me until you said "Core collapse, …...fusion at the center". This is absolutely NOT what is going on in an AGN, it is a vortex or electromagnetic confluence of electrons, plasma, and other material. How can a center "collapse" and also spew out material in the form of "jets". Can both happen simultaneously. Just my humble opinion....

[@stevensmith797]

Yes , a core of a star can collapse and spew out jets at the same time , ever here of gama ray bursts , same thing
