Refining the story of superdense objects....

[CalliArcale]

A dense cluster of stars called Westerlund I has been theorized capable of producing a medium-sized black hole through the repeated collisions of stars. But a search by the Chandra X-ray Observatory found no black holes. It did, however, find a neutron star pulsing once every 10.6 seconds, which sheds light on just what limits there are on the size of a stellar black hole's progenitor.<br /><br />Chandra Photo Album: Westerlund I <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>
