Baby Universe's 1st Picture
Observations by NASA's COBE satellite reveal imperfections (anisotropies) in the remnant radiation from shortly after the Big Bang.
These imperfections form the seed of structure that we see in the Universe around us today.

The observed imperfections in the cosmic microwave background, while they form the seeds for structures that we see in the Universe
today were actually miniscule in size, representing changes from the surroundings of just one part in 100,000.
Inflation in the Universe
The uniformity of the cosmic microwave background also posed problems for cosmologists because the background was too smooth.
Theorists propose inflation as a possible solution to this "smoothness" problem.
Fool-Proofing Galactic 'Candles'
One class of supernovae appears to be a standard candle that astronomers can use to determine the distances to remote galaxies.
This article introduces that concept through a recent revision to the distance scale.
Pulsar Gravitational Waves Win Nobel Prize
A further confirmation of Einstein's General Theory of Relativity is honored with a Nobel prize for a pair of scientists
who discover proof of the existence of gravitational waves.
Dark Matter Hunt Heats Up
The mystery of dark matter just deepened. A new report takes a look at a huge mass of dark matter (equal to about the
mass of about 20 trillion Suns) located in a small cluster of galaxies. Dark matter isn’t visible and scientists can’t
explain what it is.
