What is the Hubble Space Telescope?

A telescope is something you look through that magnifies an object by A LOT, usually. The Hubble Space Telescope isn't an ordinary telescope. It is orbiting Earth at around 17,500 mph, or 7823 m/s (meters per second). The Hubble Space Telescope was launched into a low earth orbit on April 24th, 1990 by the NASA Space Shuttle (Atlantis) and has been orbiting alone since. Vehicles use to service this Space Telescope (only the Space Shuttle), but we do not have any vehicles capable of doing so right now.

The Hubble Space Telescope isn't the kind of Telescope that you look through, it contains a computer, takes extremely zoomed in images of stars, exoplants, nebula's, galaxies, black holes, supernovas, and more. It sends these images back to scientists, engineers, and more back here on Earth to observe them and enhance them to make more sense out of them. The Hubble Space Telescope will be replaced with the James Webb Space Telescope in possibly 2021, which will be launched atop an Ariane 5 Rocket, developed by Arianespace.

The Hubble Space Telescope has 6 cameras, and the Telescope costs about $2.5 billion. One of the reasons that the Hubble Telescope is capable of taking such amazing images of other objects millions of light-years away, is because it does not have to deal with Earth's atmosphere. Earth's atmosphere blocks a lot of light from coming into the atmosphere, resulting in a lot of stars' light being weakened, or abolished. This telescope is orbiting about 500km above Earth's surface. The reason we use KM is that it is more modern and most individuals who refer to an orbit measure its apogee and perigee in KM, and its distance from Earth's surface. The Hubble Space Telescope has helped us learn a lot about space, and the James Webb Space Telescope will help us learn even more.

Starship SN10 Aborts at T - 0 Seconds for its 10km test flight.

  Moments ago, Starship SN10 attempted a flight to 10km, to then orient itself into a unique horizontal bellyflop position, flip itself upright after it has descended to about 1km, deploy the landing legs, and touch down on the landing pad softly. This vehicle, Starship Number 10, uses Liquid CH4 (methane) and Liquid Oxygen aka LOX/LO2, used by its 3 powerful Raptor engines.  Today, SpaceX started their official stream for the Starship SN10 Flight. SpaceX have privated the stream replay, so we cannot replay it. In case you want the link: The vehicle began fueling up with Methane and LOX, and then shortly after, it started the engine chill process, which is the process of chilling the engines down in preparation for engine ignition, so the engine material does not crack or get damaged from sudden shock. The vehicle attempted to start up its 3 Raptor engines, by opening the fuel & oxidizer valves, starting up the turbopumps, sho

What is “the best” programming language?

Programming languages, there are so many of them. Some programming languages are way easier to learn than other ones. But which programming language, is “the best” programming language? This question, it is not really answerable. There is no “best programming languages”, they are all meant for different things, well, MOST of them. If I were to compare 2 different programming languages, meant for very similar things, like Batch and Bash, I would say Batch is easier, as its Syntax is not as confusing as Bash’s to the average person. Here is another example, C# is primarily used for computer applications, mostly on Windows, and HTML is a markup language, being used to make websites. I cannot compare C# (it is pronounced “See Sharp” if you didn’t know) because they are used for completely different things. It wouldn’t make sense to say, “C# is way better”, because what is it better at? Developing desktop applications? Sure! Then I can say HTML is better at making websites, it is not a logi

How do you know the universe was not created a few minutes ago?

       The universe is the giant area of space that we live in, which is observable. Anything past our universal border is not in our universe. People do say the universe is constantly expanding, but there is no proof of that, as the "imaginary" or, maybe not imaginary border at the "end" of our universe. But, how do you know that the universe even exists? Were you even in it last week? Did last week even exist? Last week, the universe could have been created, and you do not have proof against it. All of your knowledge and memory could have easily popped into existence a few seconds ago, tricking you into thinking you have existed for longer than you think. This is likely, but also unlikely, it is a 50/50 chance. A reason that this is unlikely is, there are a lot of things that do not make sense in our universe. Like, why does matter attract matter, resulting in gravity? This exists in our universe, but can it exist in a different universe? Not really, or most likel
