What does space smell like?
As it turns out, space actually does have a distinct odor.
Astronauts returning from space claim that their suits smell, in a word, burnt.
The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes..
What are the 5 most visible planets from Earth?
The five brightest planets – Mercury, Venus, Mars, Jupiter and Saturn – have been known since ancient times and can easily be seen with the naked eye if one knows when and where to look. They are visible for much of the year, except for short periods of time when they are too close to the Sun to observe.
How fast is the Milky Way moving through space?
1.3 million miles per hourThe motion that’s left must be the particular motion of our Galaxy through the universe! And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)!
Are there many Milky Ways?
‘ In some estimations there are 30,000 galaxies in what became known as the ‘Hubble Deep Field. … All but six of the points of light in this image are galaxies, or as you put it ‘other Milky Ways. ‘ In some estimations there are 30,000 galaxies in what became known as the ‘Hubble Deep Field.
What are the 4 types of galaxies?
There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular.
Can astronauts fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
Why can’t you see the stars in space?
Fast exposure times means they can get good pictures of the bright Earth or lunar surface, but it also means no stars in the picture. Even in space, stars are relatively dim, and simply don’t produce enough light to show up in photos set for bright sunlight.
Can astronauts see stars?
So yes, it is possible to see the brightest stars and planets in daylight from the space station. … The Apollo astronauts all landed in the daytime when the sun was up and reported that the brighter stars were visible when they stood in the shadow of the lunar module and raised their protective outer visors.
How many Earths can fit in the Milky Way galaxy?
Dividing the volume of the Milky Way by the volume of the Earth, you get (6.7 X 10^(51))/(10^12) =~ 6.7 X 10^(39) Earths that can fit in the volume of the Milky Way galaxy.
Do we actually know what the Milky Way looks like?
One gets a rough idea of the shape of the Milky Way galaxy by just looking around–a ragged, hazy band of light circles the sky. … That observation indicates that our Milky Way Galaxy is a flattened disk of stars, with us located somewhere near the plane of the disk. Were it not a flattened disk, it would look different.
Is the Milky Way moving?
The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).
How is the Milky Way visible from Earth?
The Milky Way is visible from Earth as a hazy band of white light, some 30° wide, arching across the night sky. In night sky observing, although all the individual naked-eye stars in the entire sky are part of the Milky Way Galaxy, the term “Milky Way” is limited to this band of light.
What are we looking at when we see the Milky Way?
The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
How many Milky Ways are in space?
The universe has around 100–1000 billion galaxies. Number of milky ways that can fit is equal to the volume of the observable universe divided by the volume of the Milky way. The milky way is an average sized galaxy with around 100–400 billion stars.
Why can’t we see the center of the Milky Way?
Dust and gas are necessary to form stars, and most stars are formed within the spiral arms. Note that we can’t really see the center of the galaxy with our eyes because there is dust in the way! Annotated image of the Milky Way. The Galactic Center is unfortunately hidden by dark dust in visible light!
What is the biggest thing in the Milky Way galaxy?
The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive. It is about 5.5 million light-years across. … NGC 604 in the Triangulum Galaxy is commonly cited as one of the largest; it’s roughly 1,520 light-years across.
Can you see the Milky Way in space?
Astronauts can see Milky Way’s clouds from International Space Station. … Free from Earth’s atmosphere, they are able to see incredible views of the clouds of the Milky Way, a sight that is lost to many Earthlings caught in the glow of light pollution on the planet.
What does our galaxy look like from space?
From Earth at certain times of year, the Milky Way is visible overhead in the night sky from dark locations (you can’t see the Milky Way from under bright city lights). It looks like a giant swath of milky haze in the sky, which is where it gets the name.
