Dragon Docks with the International Space Station

Vid: Ponder the exacting systems engineering, reliability testing, required qualifications and multiple i/o instrumentation and control involved. Observe the precise, corrective jets to keep the process under control. This, is how a good future is going to be built: near earth colonisation and Lunar colonisation are the first stages to Solar system colonisation. (Note, they Read More…

Typical images of the solar system are NOT to scale, showing the planets at grossly exaggerated sizes. Here is a typical case, HT Wikimedia, WP and Planet User: So, some video makers did a little project to show it to scale, out to Neptune . . . beyond, lies vastly more of course, but Pluto Read More…

Galileo’s contemporary science opponents made a lot of sense

Christopher Graney: “… seen from Earth, stars appear as dots of certain sizes or magnitudes. The only way stars could be so incredibly distant and have such sizes was if they were all incredibly huge, every last one dwarfing the Sun. Tycho Brahe, the most prominent astronomer of the era and a favourite of the Establishment, thought this was absurd, … ” The true history is a warning to thoughtful people to avoid popular science written by the village atheist; he knows just enough to get it all wrong.

Betelgeuse dims, astrophysicists speculate

Since about October 2019, Betelgeuse (the bright reddish star at Orion’s shoulder in the brightest constellation in the sky that is about 600 – 700 ly distant from us) has begun a sharp dimming that has now gone beyond what has been seen in modern observations. As of the end of January, it was down Read More…
