    Didn't Captain Kirk fight the Gorn here ?

    My one question is : Are they approaching each other, passing each other or departing ?

    The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/ESA Hubble Space Telescope. Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies. Hubble's Advanced Camera for Surveys captured this drawn-out galactic interaction.

    Andromeda is heading toward the Milky Way...A collision will occur eventually...My question is: If everything is/has been blown away from the centre of the Universe, how do things like galaxies collide? Should they not both be moving away from the centre of the Universe and, on different trajectories, be moving slowly AWAY from each other (until eventually wink out of sight)

    If I understand the "Theories" correctly everything must be somewhat static with the expansion stretching Space itself. Inside of that there are areas of Galaxy clusters moving in flux with each other sort of like Solar systems.
    My question is, How do they derive in which direction. Hubble's law, which is constantly changing to coincide with new observations from better telescopes, doesn't show any angular motion. What if the Universe is rotating? The larger the radius the flatter the curve and the greater the distance observed the direction is harder to detect. We see things as they were not where they are.
    I once watched a C5 Galaxy (coincidentally) flying in the distance and it appeared to be floating above the ground moving really slow. A Cessna flying by later was moving at a third of the speed but looked like it was really moving along. Relativity.

    One thing I find curious, several articles about the asteroid danger have said that we've identified 99% of near-earth objects, as they are called. How can we say that unless we know for certain how many there are?

    Dark matter is a relatively unknown quantity in galaxy movement.

    The attraction of gravity is the other.

    We have found 99% of NOEs that are 1 kilometer or larger(these are planet-killers). The number is an estimate based on how many are found in an observed(given) part of space. It is only an estimate.

    However, we have only found about 40% of NOEs 140 meters or larger(that could cause massive regional devastation). 10,000 out of an estimated 25,000.

    This reinforces my confusion/question about the actual direction of an Expanding Universe. The difficulty in determining the direction - toward, away or oblique angle - of a visible object from a distance of "only" 2.5 million lightyears shows the near impossibility of knowing the true direction of something billions of years away.
    Also considering all measurements are based on visible light being equal to a certain class of Stars which they now claim varies.

    The James Webb Space Telescope photographed a collision of two galaxies that's sparking a flurry of star formation invisible to other telescopes.

    The wave of star birth was triggered by the encounter of two galaxies known by the common name IC 1623. The merging couple is producing stars at a rate 20 times faster than that of our own Milky Way galaxy, scientists said.

    Hubble Space Telescope, which specializes in detecting optical light (the kinds of wavelengths visible to the human eye). But because IC 1623 is wrapped in a thick shield of dust, astronomers had not been able to peer deeper inside the galaxies to see the forming stars.

    "On October 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from a distance of 890,000 miles (1.4 million km). The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provide Lucy with the speed required to reach the Trojan asteroids — small bodies that orbit the Sun at the same distance as Jupiter. On its 12 year journey, Lucy will fly by a record breaking number of asteroids and survey their diversity, looking for clues to better understand the formation of the solar system."

    The image was taken with Lucy’s Terminal Tracking Camera (T2CAM) system, a pair of identical cameras that are responsible for tracking the asteroids during Lucy’s high speed encounters. The T2CAM system was designed, built and tested by Malin Space Science Systems; Lockheed Martin Integrated the T2CAMs onto the Lucy spacecraft and operates them.

    The Moon is very dim on the far left.

    I had this in the lid of my toolbox for nearly 20 years when I "worked, haha", in a Caterpillar factory.

    Think it's about time to put a larger version in my Shed -Man hide-a-way.

    Which Cat plant? When I was at Purdue I'd go by the one in Lafayette and smile. Fourteen years at Purdue and not a single day's honest labor. I was so pround.

    East Peoria, Illinois. One time World headquarters - before Caterpillar Tractor Company became Cat INC.

    I too spent many days looking busy but after 35 years decided it was time to let them pay me to stay home.

    Don't worry no one is watching you.

    "NASA successfully launched the third in a series of polar-orbiting weather satellites for the National Oceanic and Atmospheric Administration (NOAA) at 1:49 a.m. PST Thursday, as well as an agency technology demonstration on a United Launch Alliance Atlas V rocket from Vandenberg Space Force Base in California.



    In addition to the newest Joint Polar Satellite System or JPSS-2, also aboard was NASA’s Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, a test of inflatable heat shield technology that could one day help land astronauts on Mars.



    Mission managers for NOAA's JPSS-2 confirm the satellite is now in Sun acquisition mode (initial operations mode) with the solar array fully deployed. The operations team will continue to evaluate an earlier solar array deployment issue, but at this time, the satellite is healthy and operating as expected. The team has resumed normal activities for the JPSS-2 mission. "
