Hace 23 horas · Stellar flybys that pass within 0.8 light-years of the Sun occur roughly once every 100,000 years. The closest well-measured approach was Scholz's Star, which approached to ~ 50,000 AU of the Sun some ~70 thousands years ago, likely passing through the outer Oort cloud.
Hace 2 días · The Hubble length or Hubble distance is a unit of distance in cosmology, defined as — the speed of light multiplied by the Hubble time. It is equivalent to 4,420 million parsecs or 14.4 billion light years.
Hace 23 horas · Details. This NASA/ESA Hubble Space Telescope image features the barred spiral galaxy NGC 3059, which lies about 57 million light-years from Earth. Hubble’s Wide Field Camera 3 collected the data in May 2024 as part of an observing program that studied a number of galaxies. All of the observations used the same range of filters: partially […]
The Sun contains almost ALL of the material in our solar system. 99% of it. All the planets, asteroids and comets add up to less than 1% of the total. The Sun is so far away that it takes light about 8 minutes and 20 seconds for it to get to us – and light is the fastest thing in the universe.
Hace 2 días · The most distant galaxy observed as of October 2016, GN-z11, has been reported to be 32 billion light-years away, a vast distance made possible through spacetime expansion (z = 11.1; comoving distance of 32 billion light-years; lookback time of 13.4 billion years).
Hace 4 días · The Short Answer: Although humans can't hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! We travel one year in time between birthdays, for example.
