The mass and redshift distribution of the largest objects in the universe are potentially interesting tests of ΛCDM, probing the initial conditions, non-Gaussianity, and the behavior of gravity on large scales. We discuss A2163 and A370 as candidates for the most massive cluster in the ...

all four clusters – each with a mass of at least several hundred trillion times that of the Sun – will merge to form one of the most massive objects in the Universe. X-rays from Chandra are shown
contains one of the most massive stars in the universe: WR 102a.NASA/Spitzer Space Telescope. The star itself is heavily obscured by dust, which is heated by the star's radiation. The dust then glows in infrared light, which allows infrared-sensitive Spitzer to "see" it. ...
ingredient is two elliptical galaxies that already have depleted cores. This means that the shape of the light profile and the trajectories of the stars contain valuable archaeological information about the specific circumstances of core formation in this galaxy – as well as other very massive ...
With this in mind, it's a bit easier to figure out what's in the running for the most massive thing in the universe. The award could go to different entities depending on the scale being considered, but each prizewinner has provided scientists insights into the limits of size and mass ...
Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial o...
Scientists discover most massive black hole in the local universe At 40 billion solar masses, this black hole breaks records.by Claire Cameron Dec. 4, 2019 Matthias Kluge/USM/MPE In a galaxy 740 million light-years away, there lies a monster. The galaxy, Holm 15A, is one of several that...
The seemingly sudden disappearance of the star was unusual, as, according to the researchers, such a massive stellar body would be expected to explode in a cataclysmic supernova upon ending its life cycle. “We may have detected one of the most massive stars of the local Universe going gently...
From the humble trillion to Graham's number, here are some of the most massive numbers ever conceived by humans.
