Why can the Hubble Space Telescope make very detailed images in visible light?
Because our atmosphere blocks or partially absorbs certain wavelengths, Hubble’s position 340 miles above Earth’s surface puts it in a location where it can capture details of objects that would be difficult or impossible for ground-based telescopes to observe.
Why are some images from the Hubble telescope are reflections of the distant past?
Hubble uses two mirrors, laid out in a Cassegrain telescope design, to collect and focus light. After light travels down the length of the telescope, it hits the concave, or bowl-shaped, primary mirror. The light reflects off of the primary mirror and travels back toward the front of the telescope.
Why can the Hubble Space Telescope see much further into space and produce much clearer images than telescopes on Earth?
Why is Hubble able to see so much better than telescopes on Earth? Because it is above the Earth’s atmosphere. So Hubble’s images are much sharper than those from other telescopes. Also, Hubble is able to see in ultraviolet wavelengths that are blocked by the Earth’s atmosphere.
Is space really colorful?
Space emits a range of wavelengths of light, some we can see others we can’t. However it doesn’t record any color but it has got filters which enable it to capture only a certain required wavelength of light.
Why can you not see stars in space?
The stars aren’t visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
What happens if I fart in space?
Surprisingly, that isn’t the biggest problem associated with farting in space. Though you’re definitely more likely to worsen a small fire when you fart, it won’t always injure or kill you. The worst part about farting in space is the lack of airflow.
Can you touch stars in space?
4 Answers. Surprisingly, yes, for some of them. Small, old stars can be at room temperature ex: WISE 1828+2650, so you could touch the surface without getting burned. Any star you can see in the sky with the naked eye, however, would be hot enough to destroy your body instantaneously if you came anywhere near them.
Would a dead body decompose in space?
Depending on where you are in space, this will take 12-26 hours, but if you’re close to a star, you’ll be burnt to a crisp instead. Either way, your body will remain that way for a long time. Gut bacteria will start to eat you from the inside out, but not for long, so you will decompose very slowly.
Is there a man floating in space?
Bruce McCandless became the first astronaut to float in space untethered, thanks to a jetpack-like device called the Manned Maneuvering Unit.
Do you age slower in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
