Normally, I would be skeptical of such supernatural claims, but having grown up near That means its a much hotter star than our sun; its surface temperature is about 17,000 degrees Fahrenheit (9,400 Celsius) in contrast to our suns 10,000 degrees F (5,500 C). Where will the northern lights appear? "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says. The methods to measure stellar distances greater than a few thousand light years include: Proper motions: All stars move across the sky, but only for nearby stars are these motions perceivable, and even then it takes decades or centuries to measure. When we use powerful telescopes to look at distant objects in space, we are actually looking back in time. The rotation curve, which describes the motion of the galaxy can be used to determine the amount of mass within a given radius from the center. The most luminous Cepheids can be used to estimate distances to objects as far as 12,000,000 light years away. There are complications in using the period-luminosity relationship. Treat yourself! How is the acceleration of gravity calculated for planets. This image makes the Milky Way appear much more galaxy-like and less like the smudge of stars we see stretching across our night sky.
