What is H alpha filter?
An H-alpha filter is an optical filter designed to transmit a narrow bandwidth of light generally centred on the H-alpha wavelength.
This combination will pass only a narrow (<0.1 nm) range of wavelengths of light centred on the H-alpha emission line..
How do astronauts poop?
Tthe poop is sealed inside a plastic bag and hauled off the next space trash day, Whitson said. … When it’s too full, astronauts must “put a rubber glove on and pack it down.” That’s what happens when the ISS toilet is working.
What happens if you stare at the full moon?
The moon itself does not reflect anywhere near enough light to harm your eyes. It is safe to look at, even with a telescope. … However a lunar eclipse (the kind that occurs at night during some full moons) when the earth blocks the sun from the moon is completely safe to watch.
Is it OK to look at the moon with binoculars?
Answer: Most certainly! You can often get the best views of the moon through binoculars. … Binoculars are suitable for viewing the Moon, especially if you wish to see the full lunar disc and want a quick view, with minimal set-up time. Also, binoculars are extremely portable.
Can you look at stars with a telescope?
Telescopes are wonderful! They let you peer into the vast unknown and see stars, planets, nebula and galaxies far, far away. … Telescopes come in many different sizes. The Moon, Jupiter, Saturn and the Orion Nebula and are terrific to see with smaller telescopes.
Is the flag still on the moon?
Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
Why do I feel weird on full moons?
A new study found that humans get less sleep and less deep sleep during a full moon. … Swiss researchers found that even in rooms in which the moon and outside environment cannot be sensed, the same holds true.
Can you look at a full moon?
For the moon to be visible during the day, it must be up in the sky at the same time as the sun, but not so close to the sun in the sky that you can’t see it. The full moon rises at sunset, is up all night, and sets at sunrise, so you can’t see a full moon in the daytime.
Can you get energy from the moon?
The Moon’s energy has been a power source for several decades, wherein its gravitational pull has been harnessed to spin generators. Similarly, tidal power plants have been arranged like hydroelectric dams to trap water during high tide and then during low tide, release it through turbines.
What do filters do for telescopes?
Like a photographic filter, telescope filters enhance details and improve contrast. They do this by cutting out unwanted colors, or wavelengths of light. Professional astronomers may use filters for technical observations, such as classifying stars.
Can you see the mirror on the moon?
As you’re well aware, no telescope on Earth can see the leftover descent stages of the Apollo Lunar Modules or anything else Apollo-related. … Hubble’s 94.5-inch mirror has a resolution of 0.024″ in ultraviolet light, which translates to 141 feet (43 meters) at the Moon’s distance.
Are there any dead bodies in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
What magnification do you need to see the moon?
A low magnification of around 50x will show you the whole moon and give you the “big picture.” But to see the moon at its best, try a high magnification, at least 150x. The moon can tolerate high magnification better than any object in the sky. This also has the added benefit of reducing the glare from the moon.
Do light pollution filters work?
LPR filters don’t reduce all forms of light pollution, despite their name. They do little to reduce the impact of car headlights, lights directed onto buildings, and other fixtures using incandescent bulbs that (unfortunately for astronomers) emit all visible wavelengths.
What is a CPL filter?
A CPL filter – which stands for circular polarizer/linear – is a glass attachment that can reduce the glare from reflected surfaces.
Why did we stop going to the moon?
But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
What can you see on the moon with a telescope?
Neophytes to astronomy might initially consider this a come-down, but are then pleasantly surprised the first time they look at sky objects with a pair of binoculars; they can reveal many sights that most folks think require a telescope – including the crescent phase of Venus, the four Galilean satellites of Jupiter, …
Can you damage your eyes looking at the moon through a telescope?
The light reflected from the moon’s surface has an intensity level very very small compared to that of the sun. So, there is no chance of damaging your eyes by looking at a full moon. However, the brightness of the full moon through a reasonably powered telescope can certainly make your eyes feel dazzled.
Can a telescope see the flag on the moon?
Can you see an American flag on the moon with a telescope? Even the powerful Hubble Space Telescope isn’t strong enough to capture pictures of the flags on the moon. But the Lunar Reconnaissance Orbiter, the unmanned spacecraft launched in 2009, is equipped with cameras to photograph the moon’s surface.
