WebApr 13, 2024 · Now for the first time, astronomers have measured the three-dimensional shape of one of the biggest and closest elliptical galaxies to us, M87. This galaxy turns out to be "triaxial," or potato-shaped. This stereo vision was made possible by combining the power of NASA's Hubble Space Telescope and the ground-based W. M. Keck … WebSep 18, 2014 · The units of time are the current Hubble time, $1/H_0 \approx 14.5$ billion years, so $1$ on the time axis corresponds to $14.5$ billion years. Note that the line does not go through the point $(1,1)$ because the current Hubble time is greater than the age of the universe , $13.798$ billion years.
