A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. Stars from both galaxies will be thrown into new orbits around the newly merged galactic center. It’s possible that – by 4 billion years from now – the increase in the Earth’s surface temperature will have caused a runaway greenhouse effect, perhaps similar to that going on now on the planet next door, Venus, whose surface is hot enough to melt lead. So that means if you could see the core of the Milky Way, you’d be observing light that possibly left Earth before humans first settled in North America.At the center of the Milky Way is one of the strangest and deadliest things in the universe: a black hole. Earth is located about halfway between the center of the Milky Way and its outer edge. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. Billions of years from now, Earth’s night sky will change as the Andromeda galaxy rushes toward a merger with the Milky Way. The Milky Way is shaped like a huge whirlpool that rotates once every 200 million years. by Matt Williams, For thousand of years, astronomers and astrologers believed that the Earth was at the center of our Universe. that which is visible) in our galaxy, with the remainder being the stars. Theoretical models had predicted that the old stars—which far outnumber young stars—should have a steeply-rising density near the black hole, a so-called A small portion of a gigapixel color mosaic of the Milky Way's heart.Red giant stars coexist with white, Sun-like stars.The center of the Milky Way – image taken by ISAAC, the The central parts of the Milky Way, as observed in the near-infrared with the NACO instrument on Infra-red image of the center of the Milky Way revealing a new population of massive stars

The Andromeda Galaxy moves towards the Milky Way Galaxy, and will meet it in about 3.75 billion years. The Milky Way Galaxy is an immense and very interesting place. It is 8.2 ± 0.4 kiloparsecs (26,700 ± 1,300 ly) away from Earth in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius where the Milky Way appears brightest. And discerning our location within it has been no simple task.

What’s more, our sun is evolving, too.

The last time the Solar System was in this position in the Milky Way, there were still dinosaurs on Earth.

The Milky Way is one of the largest galaxies in the group, second to the Andromeda Galaxy. Arcing overhead, a faint band of light may appear that looks like milk spilled across the sky.

They also think that each star has at least one planet, which means there are likely to be hundreds of billions of planets in the Milky Way – billions of which are believed to be the size and mass of the Earth.As noted, much of the Milky Way's arms is made up of dust and gas.

If you’re on a dark countryside hill some night, look up at the sky. Much the same is true about our Solar System's position within the Milky Way. In fact, the Canis Major Dwarf Galaxy is the closest galaxy to the Milky Way because its stars are currently being added to the Milky Way's disk. Well, this gallery is just the solution! It measures 220,000 light years in diameter, and has an estimated 400-800 billion stars within it.If you could travel outside the galaxy and look down on it from above, you'd see that the Milky Way is a barred The spiral arms are formed from density waves that orbit around the Milky Way – i.e. The Sun is in a finger called the Orion Spur. (A* is scientist-code for “A-star.”) Its gravity, or attractive force, is so strong that it pulls in anything that gets too close, including stars.
