Where in the Milky Way would you be most likely to find an ionization nebula?
Where would you be most likely to find an ionization nebula? the orbits of stars in the galactic center.
What is the shape of the Milky Way’s halo?
The team’s results suggest the distribution of dark matter around the Milky Way is complex. Closer to the disk of our Galaxy, where the dark matter is expected to be most dense, the halo takes the shape of a squashed sphere—a bit like a pumpkin, with the pumpkin’s top pointing out of the galactic plane.
What evidence supports the galactic fountain model?
What evidence supports the galactic fountain model? We see hot gas above the disk of the galaxy and cool gas that appears to be raining down from the halo. What is the most common form of gas in the interstellar medium? What produces the 21-cm line that we use to map out the Milky Way Galaxy?
How long does it take the Sun to complete one orbit around the galactic Centre?
approximately 225-250 million years
What kind of object do we think lies at the center of the Milky Way galaxy?
At the very centre of the Galaxy lies a remarkable object—a massive black hole surrounded by an accretion disk of high-temperature gas. Neither the central object nor any of the material immediately around it can be observed at optical wavelengths because of the thick screen of intervening dust in the Milky Way.
What are we looking at when we see the Milky Way?
When you observe the night sky with your eyes, you can see the Moon, perhaps several planets, and many stars. If you are in a particularly dark location and if the moonlight is not too bright, you may also see a faint band of light that stretches from horizon to horizon.
What does the center of the Milky Way look like?
We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it’s very center. There is also a bulge in the middle that consists of mostly old stars. When you look at a spiral galaxy face-on, you can see beautiful spiral arms where stars are being born.
What makes the Milky Way Milky?
Our Sun (a star) and all the planets around it are part of a galaxy known as the Milky Way Galaxy. A galaxy is a large group of stars, gas, and dust bound together by gravity. 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.
Can you see Milky Way with eyes?
More than 100,000 light years in diameter, with more than 100 billion stars and at least as many planets, the Milky Way is arguably the most impressive feature of the night sky that you can see with the naked eye.
How many galaxies Does the Milky Way have?
100 billion galaxies
What does the Milky Way look like to the human eye?
To the naked eye, the Milky Way looks like a dark cloud. Not a cloud of stars, just a cloud. If a dark gray “cloud” on a pitch black sky stretches from horizon to horizon and if you notice it moves sideways every few minutes then you are probably looking at the Milky Way.
Where is the darkest place on earth?
This Remote Corner Of Nevada Is One Of The Darkest Places In The World Because of light pollution, most people in the U.S. don’t know what a full night sky looks like. But the Massacre Rim area in Nevada has recently been designated a Dark Sky Sanctuary….
Can you see the Milky Way without a camera?
If someone unfamiliar with it sees a picture of the milky way without a terrestrial reference point, they might assume it was taken with a telescope. But the scale of the milky way is huge! You don’t need a telescope to see or photograph it….
What is the best time of night to see the Milky Way?
Generally speaking, the best time to see the Milky Way is during the Milky Way season, which goes from February to October, usually between 00:00 and 5:00, and on nights with a new moon….
What months is the Milky Way visible?
From June to early August the best time is near midnight, though the Milky Way will be visible almost all night. From Mid August through September the best time is soon after the sun has set and the sky has grown dark. Below is an illustration that may help you….
When can I see the Milky Way 2020?
When is the Milky Way visible? Between March our galaxy is visible if you get up before dawn, in summer it can be seen at midnight, and by October it’s on show right after dusk. If there’s no light pollution to block your view it’s possible to see the Milky Way galaxy arcing overhead….
Is Milky Way visible from Earth?
The Milky Way is visible from Earth as a hazy band of white light, some 30° wide, arching 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.
Are any galaxies visible from Earth?
Answer: Yes, you can see a few other galaxies without using a telescope! The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
How many galaxies are they?
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to two trillion galaxies.
What does the Milky Way move around?
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)….
Does the sun move around the Milky Way?
The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane. The Sun appears to move up-and-down and in-and-out with respect to the rest of the galaxy as it revolves around the Milky Way….
How long is a galactic year?
220, 230 million years
Does the Milky Way rotate clockwise or counterclockwise?
In space there is no up or down. The MilkyWay rotates in the direction in which the arms trail the rotation movement. Also keep in mind the solar system’s ecliptic plane is not in the same general plane of the Galaxy.
