How would you feel if you were in space?
Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time. The astronauts inside it experience weightlessness, floating around in no particular direction.
Do you feel G forces in space?
g-force is the result of acceleration of a space craft. If the ship were traveling at a constant velocity, the astronaut would experience no force at all, regardless of how fast the ship is going. Astronauts can feel g-force at any speed, so long as the ship is accelerating.
Can you float off the moon?
Yes, we could float off into space on the moon as long as we jumped high enough. That’s probably a lot higher than you’d think. You’d have to propel yourself at 2.38 km/second to get that high.
How to plan deep sky observing projects?
Plan your deep-sky observing projects accordingly. Also, light pollution tends to improve a bit after 11 or midnight as some outdoor lights get turned off. Keep an eye on the daytime sky. The deeper and cleaner the blue is in the afternoon, the cleaner and darker the air will be at night. Moonlight, of course, is nature’s own light pollution.
What is ‘deep space’?
The International Telecommunications Union has reserved some frequency bands for “deep space” which it defines as beyond two million kilometres from Earth (about five times as far as the Moon).
Why can’t we see deep-sky objects with telescopes?
With deep-sky objects, on the other hand, a telescope’s main function is to collect a lot of light for your less-than-sensitive eye. The main obstacle to seeing deep-sky objects is not that they’re too small to see without optical aid. It’s that they’re too dim. Accordingly, deep-sky observing involves its own techniques.
What are some of the most interesting objects in space?
Much more interesting — but generally more difficult — are deep-sky objects: nebulae, star clusters, and galaxies. Hundreds of these ghostly glows and subtle spatterings are within reach of a modest telescope.
