The first link leads to an older article that does explain it. What they mean is that the planets’ orbits are in resonance, which means that their orbital periods are related by integer ratios. (For example one planet completing exactly three orbits in the time it takes another to complete two)
Our navy terrorizes most of the world. The US Army just figured out Class A uniforms. There is no reason why the Bundeswehr should outshine us in uniform design. It’s a tailoring gap we must overcome before we can conquer ze world. So you have nothing to worry about, except coming up with better comments.
It’s not a secret, just hard for amateurs to do. No doubt states with space monitoring equipment always knew. He just did it with a camera in his backyard and his laptop.
Also, he’s Finnish.
Amateur observations of the spaceplane indicate it is flying in a highly elliptical orbit ranging between 201 and 24,133 miles in altitude (323 and 38,838 kilometers). The orbit is inclined 59.1 degrees to the equator.
This is not far off the predictions from the hobbyist tracking community before the launch in December. At that time, enthusiasts used information about the Falcon Heavy’s launch trajectory and drop zones for the rocket’s core booster and upper stage to estimate the orbit it would reach with the X-37B spaceplane.
Good question. According to this article, the process going on with Betelgeuse does sound like the same or very similar to the process described in OP’s article.
The great dimming [of Betelgeuse] was caused by the star spitting out a lump of gas and dust, like chewing gum: or what scientists call a “surface mass ejection” caused by an “anomalously hot convective plume”.
OP’s article doesn’t say that the Old Smokers they found are red super-giants but since they called them old smokers, I’m inclined to think that they are. Also because they say that smoke contains much higher levels of heavy elements than is common in the region which would also be consistent with older stars. The article doesn’t say whether or not the stars puff out smoke on a regular schedule like Betelgeuse does, but then maybe they haven’t been watching them long enough to see a pattern yet.
It does seem like they found a bunch of older stars that are pre-supernova, just like Betelgeuse is, and burping out clouds of gas and dust.
I missed it at first as well. The second paragraph implies they are red giants. However, there is a distinction between a red giant and a red super-giant, if that is what you mean.
The “peculiar” puffing behavior of these stars has never been seen before in such red giants, astrophysicist Philip Lucas told AFP.
So, in my typical nature, I went right to the source and shot off an email to Professor Philip Lucas from the University of Hertfordshire. He was one of the primary researchers for the original paper. (P.W. Lucas et al.)
The laser array is expensive but if it’s continuous and spread out enough you could keep sending newer probes. Or if it’s not continuous you could use it for different directions!
According to Scott Manley’s video on the topic the probes would need to arrive at the correct time in order to form what is effectively a huge phased array antenna.
Only then is the combined transmission power of these tiny probes large enough to be received on earth.
