Milky Way

The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), [10] but only about 1,000 light-years thick at the spiral arms (more at the bulge).

NASA Animation Sizes Up the Universe''s Biggest Black Holes

The black hole at the heart of our own galaxy, called Sagittarius A* (pronounced ay-star), boasts the weight of 4.3 million Suns based on long-term tracking of stars in orbit around it. At the animation''s larger scale lies M87''s black hole, now with a updated mass of 5.4 billion Suns. Its shadow is so big that even a beam of light

The Milky Way Galaxy

Our Solar System is about 25,000 light years away from the center of our galaxy – we live in the suburbs of our galaxy. Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way. It takes 250 million years for our Sun and the solar system to go all the way around the center of the Milky Way.

Show our place in the galaxy and note that on this scale, our Sun is too small to be visible. Note that the Milky Way Galaxy is flat like a disk and on this scale would be less than an inch thick. Tilt the model and show how our perspective shifts when seeing it

The Milky Way: Earth''s home galaxy | Astronomy

The true scale of the Milky Way Galaxy — and, indeed, the universe as a whole — became dramatically clearer in the 1920s. Our galaxy — indeed, most galaxies — may have been built by

Our Galaxy

Our Galaxy - Evolution and Formation: In a way, galactic formation is similar to stellar formation, only on a much larger scale. With the early Universe mixed with Dark Matter and gases containing molecular hydrogen, collisions eventually occurred. Collisions led to conservation of energy eventually resulting in collapse.

How Big Is the Solar System?

Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale. Jupiter''s diameter is about equal to the thickness of a U.S quarter in our shrunken solar system. Saturn is on the field at 19 yards from the goal line. The ringed world is about 887 million miles (1.4 billion kilometers) from the

Our Milky Way Galaxy: How Big is Space?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for

If the Moon Were Only 1 Pixel

Those things are too much for our brains to handle. But all this empty space, these things of a massive scale, really are more than our minds can conceive of. The maps and metaphors fail to do them justice. You look at one tiny dot, then you look for the next tiny dot. Everything in between is inconsequential and fairly boring.

The Milky Way: Understanding Our Place in the Galaxy

The Milky Way''s gravity affects two satellite galaxies, the Large and Small Magellanic Clouds, visible from the Southern Hemisphere and orbiting at varying positions around our entire galaxy. The Large Magellanic Cloud, about 14,000 light-years in diameter and 163,000 light-years away, may lose gas and dust to the Milky Way due to gravitational

Galaxy Formation and Evolution

Since our galaxy grew by merging with and eating other galaxies, traces of that violent past are visible in the form of streams of stars that were pulled from other places. (DESI) consortium is conducting a five-year survey to map the large-scale structure of the Universe over one-third of the sky and 11 billion years of cosmic history

Our Milky Way is only one of billions and billions of galaxies. If our Milky Way were scaled to the size of a 250mm paper plate, how far away would the

Relative Sizes of the Earth and the Milky Way Galaxy

Question: Hi, I just want someone to verify my math –needed to visualize the scale of the galaxy. I found that if the Earth were the size of a grain of salt (0.004 inches) the diameter of the Milky Way would be about 5.1 million miles. Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km

The Milky Way Galaxy

The Milky Way is our galactic home, part of the story of how we came to be. Astronomers have learned that it''s a large spiral galaxy, similar to many others, but also different in ways that reflect its unique history. Living inside the Milky Way gives us a close-up view of its structure and contents, which we can''t do for other galaxies. At the same time, this perspective makes it
