David, I was starting to read “Submillimetre Astronomy” by Watt and Webster and they were talking about molecular clouds. They mention the magnetic energy density being approximately equal to the kinetic energy density, then talked about a cascade of scales. It has been on my mind to check how much nuclear energy in generated in

DOUBLE VORTEX solves mystery of Saturn’s rotation | ft. Tom Stallard & Nahid Chowdhury https://www.youtube.com/watch?v=pVlV7Er_jFU Does this apply to galaxy rotation? I would much rather hear that a relatively small bit of charge and magnetic field – changes apparent rotation rates – than the bleak alternative of still more years of looking for dark matter

Hello, I have been using Sharpcap for testing cameras. But I am only now getting things set up after several years of trying to select or design the telescopes and cameras. For single cameras I am running these kinds of manual captures. I have to manually set the gain, exposure and processing steps. Then I

https://www.facebook.com/groups/172438633343696 Can someone tell me the current best all sky set up? I was thinking of one that had zoom from all sky to 30x. Any suggestions. Thanks. I was looking at PTZ low light security cameras. Dan Bush Thank you. Your picture gallery is filled with beautiful images. I searched fro Hikvision cameras and

Debbie, First, your novice videos should be globally public on your website. Either HAS is an organization devoted to all people knowing about the sky and heavens, or not. Share openly. If there are things specific to secure gatherings at private places, those should not be shared, but minimized or separate. I tell groups like

The latest possible technology that I will be trying to adapt is related to piezoelectric films and piezoelectric fibers. I have seen several efforts to use piezo disks, but not these films. As I am reading the history of these materials

When I was at the University of Maryland at College Park in the late 1970’s I met Joe Weber and Charles Misner and others who were starting gravitational wave detection. So I have followed it over the years. I think it very unlikely that aliens would be using the very narrow band of electromagnetic signals

Karen Lee-Waddell, Pete Wheeler, SKA web contact, I am trying to piece together the Internet data sharing policy for SKA from what is visible on the Internet. Is SKA data going to be available to everyone on the Internet? In accessible form? Reading these it seems SKA data is only for certain people for very

Earthquake seismograph using bismuth magnetic levitator as sensor at https://www.youtube.com/watch?v=aIANNzpec7Y Tomislav Stimac, The “standard” still for accelerometers is the small but global network of super conducting gravimeters (SGs). They use liquid helium cooled niobium magnetically levitated spheres as the test mass. The sensitivity is about 0.1 nanometers per second squared (nm/s2) at 1 sample per second.

What YOU Can SEE Through a $1 Billion, $32,000 and an $800 Telescope! https://www.youtube.com/watch?v=VwoII9TQd8k There are many countries with LOTS of people where $800 is more than the median annual income. And many more countries and many more people where $800 is more than monthly income. So here you are, posting a video that could
