If Megastar has an absolute magnitude of -4, what is the apparent magnitude?Question:If Megastar has an absolute magnitude of -4, what is the apparent magnitude?Magnitudes of Stellar Brightness:Stars in the sky
What is the absolute magnitude of Rigel?Apparent and Absolute Magnitudes:The apparent magnitude and absolute magnitude of a star both refer to its brightness but are very different measurements. Where the apparent magnitude refers to how bright the star is in Earth's night sky, absolute magnitude...
What Is Generative AI (GenAI)? Generative AI (GAI) is the name given to a subset of AI machine learning technologies that have recently developed the ability to rapidly create content in response to text prompts, which can range from short and simple to very long and complex. Different gener...
This happens about every 15 years, meaning it occurs twice during each of Saturn’s orbits around the sun. You’ll need a telescope to see the event (or not see it, I suppose). The rings are incredibly thin, only a few dozen meters thick in some parts, so they seem to disappear ...
The moment you observe the polar ice caps of Mars, the storms of Jupiter or the rings of Saturn, you will instantly be inspired to see more. All you need is some knowledge of the equipment and telescopes needed to both observe and locate them. The brighter planets can be observed with ...
What is the power factor (PF) The power factor (PF) is the ratio between active and apparent power and can take on values between 1 and -1. The Power factor is an indication of the amount of active power that is present in the transmission line compared to the apparent power that co...
rock steady , polar cap , Syrtis Major, so then in went the 4mm. Perfect! Round disc, sharp! So after many years , I found my mirror was a good one and gave excellent results under perfect but dim seeing! Saturn and Jupiter were also in the sky, This is going to be great. But...
And of course, binos have the trick of using both eyes that will provide an bit extra lift in effective aperture over a single scope of the same aperture. While I always pack my binos when I go to a dark site, my personal preference for wide field viewing is a fast scope. And I ha...
Most of Japan’s 5,000 earthquakes go unnoticed due to its low magnitude rating, or because the hypocenter (the point where an earthquake ruptures below the surface of the Earth) is far from the coast of Japan. About 3,800 earthquakes with a recording of 3.0 – 3.9 occur per year and...
A body experiences centripetal acceleration when it is forced to travel in a circle, or at least in an arc. The force that causes it to do so is called a centripetal force.
