An enormous swirling vortex of hot gas glows with infrared light, marking the approximate location of the supermassive black hole at the heart of our Milky Way galaxy. This multiwavelength composite image includes near-infrared light captured by NASA’s Hubble Space Telescope, and was the sharpest infrared image ever made of the galactic
A) There are so many stars in our Galaxy that the more distant ones are hidden behind the nearer ones. B) Distant stars are obscured by gas in interstellar space. C) Expansion of the universe has carried the more distant stars out of our view. D) Distant stars are obscured by dust in interstellar space. A- The locations of globular clusters
The Milky Way rotates at a whopping 130 miles (210 kilometers) per second, but a new study has found that dark matter has slowed the rotation of its bar by at least 24% since its formation nearly
The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big
Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water. The warped disc of our galaxy, the Milky Way.
Where t t t is the time required to rotates, θ \theta θ is the angular displacement its unit is radian and ω \omega ω is the angular frequency. For one revolution around the Milky Way gives us angular displacement θ = 2 π \theta= 2\pi θ = 2 π rad. Now we can plug our values for θ \theta θ and ω \omega ω into equation (1) to get t t
