Merope is too bright for Gaia to have a reliable parallax for it, but calculations of the overall distance to the Pleiades cluster using Hipparcos, Gaia, Hubble Space Telescope, and other methods repeatedly show that the Hipparcos parallaxes suffered from some kind of systemic error, and the distance to the Pleiades is most likely around 135 ...
This video clip shows a visualization of the three-dimensional structure of the Pillars of Creation. Closer view of one pillar. Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, in the Serpens constellation, some 6,500–7,000 light-years (2,000–2,100 pc; 61–66 Em) from Earth.

The observational result of Hubble's law, the proportional relationship between distance and the speed with which a galaxy is moving away from us, usually referred to as redshift, is a product of the cosmic distance ladder. Edwin Hubble observed that fainter galaxies are more redshifted. Finding the value of the Hubble constant was the result ...
The distance to Vega can be determined by measuring its ... The Hubble observation is the first image of ... Eventually this function became denoted by the Pleiades.
The Hubble tension is one of the most hotly debated discrepancies in all of astronomy. It centers around a number called the Hubble constant, which is functionally the rate at which our universe ...
The 2007 new Hipparcos reduction gives a statistically more accurate parallax of 8.51 ± 0.28 mas, indicating a distance of 118 ± 4 pc. [2] Analysis of Gaia parallaxes for the whole Pleiades cluster give an average distance of 136.2 ± 5.0 pc , [ 18 ] while VLBI measurements of multiple members give a distance of 136.2 ± 1.2 pc .
Located at a distance of 17,090 light-years (5,240 parsecs), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [10] It is estimated to contain approximately 10 million stars, with a total mass of 4 million solar masses , [ 11 ] making it the most massive known globular cluster in the Milky Way.
