A mining proposal. - Dear Cheap Astronomy – What’s the best way to redirect an asteroid’s path for mining purposes? Let’s start by saying CA's plan to somewhat indiscriminately crash $#!+ on the Moon is not actually that indiscriminate. It’s not realistic to think you can shift an object several kilometres in diameter out of the asteroid belt and o…

https://www.youtube.com/watch?v=p2SEbzZRwI8 Hosted by Tony Darnell. From Aug 21, 2023. Kelt-9b is a gas giant planet that orbits a star 670 light-years from Earth. It is so close to its star that its dayside temperature is 7,800 degrees Fahrenheit (4,300 degrees Celsius), hotter than some stars. This heat is so intense that it rips apart the molecu…

http://www.astronomycast.com/archive/ From November 20, 2006. The discovery of dark energy was one of the biggest surprises in astronomy. Instead of a nice, predictable expanding Universe, acted on only by gravity, astronomers turned up a mysterious repulsive force accelerating the expansion of the Universe. Fraser and Pamela explain the evidence f…

At present there are over 5,600 confirmed exoplanets in just over 4,000 star systems. Within this population, about 300–500 exoplanets fall into the curious class known as hot Jupiters — large, Jupiter-like exoplanets that orbit very close to their star. How hot Jupiters form is an area of active research. Recently the WIYN 3.5-meter Telescope at K…

From May 11, 2021. SNFactory researchers found that among about 50 supernovae, many had nearly identical spectra, paving the way for making more accurate distance calculations. These calculations, in turn, open up the possibility of using supernovae to better search for dark energy. Plus, OSIRIS-REx, Voyager I, planetary formation, and volcanoes on…

From Sept 22, 2006. You have lived on the Earth all your life, so you’d think you know plenty about planets.

From August 17, 2023. According to the NASA exoplanet archive, HAT-P-67 b holds the distinction of being the largest exoplanet in terms of size. With exoplanet classification, one always needs to be careful - especially when it comes to size and mass - because there is a fuzzy boundary with large planets where if they become too large, they are con…
