... Astronomy for Kids . ... May 2016: Gravitational waves breakthrough . ... Gravitational constant appears universally constant, pulsar study suggests . The fact that scientists can see gravity perform the same in our solar system as it does in a distant star system helps confirm that the gravitational constant truly is universal. ... Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the universe, according to a decades-long study of a distant pulsar. ...

Two groups are measuring distant supernovae with the goal of determining whether the Universe is open or closed by measuring the curvature in the Hubble diagram. The figure below shows both data sets: Perlmutter et al. (1997) and (1998) in black and Garnavich et al. (1997) in orange. The curves show a closed Universe (Omega = 2) in red, the critical density Universe (Omega = 1) in black, the empty Universe (Omega = 0) in green, and the steady state model in blue. ...

... 2004: . ... An increase in star brightness is followed by a decrease in asphericity and wind velocity to the point where stationary and even accreting fraction of the wind appears in extremely bright objects together with a flowing out fraction. ... Based on an analysis of observations obtained with BTA and on the published data it was found that degree of abnormality of energy distribution in continuum of magnetic chemically peculiar stars increases with an increase of their rotation period. ...
