WebYeah I was thinking how the furthest known galaxy is 32 bil light years away so I wondered how far it would be from earth. If the universe is expanding then we would never see anything past that point.(32 bil light years) Which is weird, because we & the galaxys outside the observable universe exist at the same moment right now, we just don't exist … Web16 mrt. 2024 · One light-year is about 9.48 trillion kilometers (5.88 trillion miles). That’s a huge distance. In our solar system, Neptune is the farthest planet from the sun at about 4.5 billion kilometers (2.8 billion miles) from our star. That’s only 0.00047 light-year. The sun’s light reaches Neptune in just 4.2 hours.

Web15 dec. 2010 · That's the distance that light travels through vacuum in 1 billion years. When rounded, it's equivalent to 5,878,450,000,000,000,000,000 miles, or … WebAstronomers talk about redshift in terms of the redshift parameter z. This is calculated with an equation, where λ observed is the observed wavelength of a spectral line, and λ rest is the wavelength that line would have if its source was not in motion: z = (λ observed - λ rest) / λ rest. z tells you the number of years the light from the ... rcvs workforce report
Astronomers precisely trace distance to oldest and farthest known galaxy
Web22 jul. 2007 · AGC 2065 is part of a huge Supercluster that includes AGCs 2056, 2061, 2065, 2067, 2089 and more – all at roughly 1 billion l.y distance. At GSSP, I took a look at AGC 2061 and picked up three of the cluster members that are also in the 1 billion light year club. This cluster is located just a half-degree northwest of 5th magnitude Eta CrB. Web12 jul. 2024 · The image showcased by Biden and NASA chief Bill Nelson showed the 4.6 billion-year-old galaxy cluster named SMACS 0723, whose combined mass acts as a "gravitational lens," distorting space to greatly magnify the light coming from more distant galaxies behind it. WebWith today’s technology, it would take us approximately 37,200 years to travel the distance of one light year. For example, if we were to travel at a speed of 58,536 km / h, which is the speed at which the New Horizons rehearsal travels on its way to Pluto, it would take us just under 20,000 years to cross the path of one light year. how to specify language in html
