    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.

    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?

    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??

  • @JoeDeglman
    @JoeDeglman 5 лет назад

    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.

    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?

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....
