10 Weird Things You (Probably) Didn't Know About the Milky Way

A small minority of sources argue that distant supermassive black holes whose large size is hard to explain so soon after the Big Bang, such as , may be evidence that our universe is the result of a , instead of a Big Bang, with these supermassive black holes being formed before the Big Bounce. Perfect logarithmic spiral patterns only crudely describe features near the Sun, because galaxies commonly have arms that branch, merge, twist unexpectedly, and feature a degree of irregularity. The low end of the estimate range is 5. Astronomers have been ardently studying them for almost a century, ever since Edwin Hubble discovered that neighboring Andromeda , but a galaxy in its own right. That glue, we now know, is dark matter.

Further information: Outside the gravitational influence of the Galactic bar, the structure of the interstellar medium and stars in the disk of the Milky Way is organized into four spiral arms. So how does an earthling perched on a pinprick of a planet tens of millions of light-years away spot a hole in that halo? Located just 26,000 light-years away. Both and planetary transit observations indicate that there may be at least as many planets bound to stars as there are stars in the Milky Way, and microlensing measurements indicate that there are more not bound to host stars than there are stars. Fowler then proposed that these supermassive stars would undergo a series of collapse and explosion oscillations, thereby explaining the energy output pattern. Moreover, the vast majority of large galaxies have a supermassive black hole at their hearts. So there are just no stars of that mass.

Astronomers first began to suspect that the Milky Way is a , rather than an ordinary , in the 1960s. Instead, the newly formed mega-galaxy will offer a night skyscape with a spectacular blend of stars and streamers unlike anything we see today. Artist's impression of how the Milky Way would look from different vantage points — from edge-on lines-of-sight, the peanut shell -shaped structure, not to be confused with the galaxy's central bulge, is evident; viewed from above, the central narrow bar that is responsible for this structure appears clearly, as would many spiral arms and their associated dust clouds Bright flares from , location of the at the center of the Milky Way The Milky Way consists of a bar-shaped core region surrounded by a warped disk of and stars. Is the supermassive black hole going to consume the Milky Way? A star that would have been orbiting happily for billions of years might get deflected into a collision course with the black hole. It should be visible if the is approximately +5.

Toward the center of the Milky Way the orbit speeds are too low, whereas beyond 7 kpcs the speeds are too high to match what would be expected from the universal law of gravitation. Same goes with the black hole at the center of the Milky Way. Unlike with , one would not experience until very deep into the black hole. It is therefore much easier to detect more massive ones, like the supermassive black hole of our galaxy. The Spiral Structure of the Galaxy: Something Old, Something New. Of course, the Sun will die in about 5 billion years, so this future won't be our problem. But over the vast eons, it could be a different story.

The habitable zone merely states that a planet is at the right distance from its star for water to remain on the surface without freezing over or boiling off. A image of galaxy , which is thought to resemble the Milky Way in appearance The Milky Way is the second-largest galaxy in the , with its stellar disk approximately 100,000 ly 30 kpc in diameter and, on average, approximately 1,000 ly 0. It is located in the fourth galactic quadrant at a distance of about 5. In this scenario, suggested by numerical simulations of the dynamics of the different spiral arms, the outer pattern would form an outer , and the two patterns would be connected by the Cygnus arm. The tidal force on a body at the event horizon is likewise inversely proportional to the square of the mass: a person on the surface of the Earth and one at the event horizon of a 10 million black hole experience about the same tidal force between their head and feet. Weiss A black hole is just a concentration of mass in a very small region, which things orbit around.

Danica Simic has been writing ever since she was a child. Once a is formed, it begins to undergo radiative cooling and the surface temperature steadily drops. However the resolution provided by presently available telescope technology is still insufficient to confirm such predictions directly. The radiating matter is orbiting at 30% of the just outside the. The precise implications for this discovery on black hole formation are unknown, but may indicate that black holes formed before bulges. But we'd expect to see some sign of it, like flares or radiation from its accretion disk.
