Astronomy Picture of the Day . Signals of a Strange Universe . ... Credit Copyright: High-Z Supernova Search Team , HST , NASA Explanation: Eleven years ago results were first presented indicating that most of the energy in our universe is not in stars or galaxies but is tied to space itself. ... Suggestions of a cosmological constant (lambda) were not new -- they have existed since the advent of modern relativistic cosmology . ... Publications with keywords: universe - cosmology . ...

... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2009 March 29 . Signals of a Strange Universe . ... Such claims were not usually popular with astronomers, though, because lambda is so unlike known universe components , because lambda's value appeared limited by other observations, and because less- strange cosmologies without lambda had previously done well in explaining the data. ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.�� Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.�� ��Albert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...
