Hace 2 días · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth.
Hace 2 días · In the widely accepted cosmological model based on general relativity, redshift is mainly a result of the expansion of space: this means that the farther away a galaxy is from us, the more the space has expanded in the time since the light left that galaxy, so the more the light has been stretched, the more redshifted the light is ...
Hace 3 días · Voyager 1 and 2 are now so far away that they are in interstellar space—the region between the stars. No other spacecraft have ever flown this far away. Where will Voyager go next?
Hace 2 días · A zoom shot is an optical change of focal length that changes the framing and makes the subject appear closer (zooming in) or farther away (zooming out) without
Hace 3 días · However, in the Northern Hemisphere, we are having winter when Earth is closest to the Sun and summer when it is farthest away! Compared with how far away the Sun is, this change in Earth's distance throughout the year does not make much difference to our weather.
Hace 5 días · On average, the moon is 238,855 miles away from us on Earth, but it's slowly slipping farther and farther away. The movement is very gradual — it only gets about 1 inch farther away every year, NASA reports. The reason it is moving farther away is because of the effects of the moon's gravity on Earth, the BBC reports.
Hace 1 día · Supernova searches fall into two classes: those focused on relatively nearby events and those looking farther away. Because of the expansion of the universe , the distance to a remote object with a known emission spectrum can be estimated by measuring its Doppler shift (or redshift ); on average, more-distant objects recede with greater velocity than those nearby, and so have a higher redshift.
