Nebulas, or vast clouds of gas that often condense to become new stars, also have impressively large sizes. NGC 604 in the Triangulum Galaxy is commonly cited as one of the largest; it's roughly 1,520 light-years across. Galaxies are collections of star systems and everything inside those...
Once it’s in that spinning disc, the matter (usually hydrogen gas as this is the most common element in the Universe) will settle into a nice, happy orbit around the black hole, far away from the point of no return: the event horizon. The event horizon is the sphere around the ...
If UY Scuti replaced the sun in the center of thesolar system, its photosphere would extend just beyond the orbit ofJupiter. The nebula of gas ejected from the star extends far beyond the orbit ofPluto, to 400 times thedistance between the Earth and the sun. Other big stars NASA's Hubb...

NASA's Chandra observations revealed in 2016 hints of the giant explosion in the Ophiuchus galaxy cluster, as they observed an unusual curved edge, potentially a part of the wall of a cavity in the hot gas created by jets from the supermassive black hole. ...
The attack on Colonial Pipeline became one of the most notorious ransomware attacks because of itsimpact on everyday Americans, with those living in Southeast states suddenly facing gas supply shortages. Colonial Pipeline, owner of a pipeline system carrying fuel from Texas to the Southeast, suffered...
This extremely powerful eruption occurred in the Ophiuchus galaxy cluster, which is located about 390 million light-years from Earth. Galaxy clusters are the largest structures in the Universe held together by gravity, containing thousands of individual galaxies, dark matter, and hot ...
While the direction of the copper price over the last few months was almost impossible to judge, gold’s record breaking run looked inevitable. At $3,420 per ounce gold at the time of writing, the yellow metal has now finally also surpassed its 1980 peak in inflation-adjusted terms. ...
