February 5, 2015 New data collected from the European Space Agency's Planck telescope shows that the first starlight in the universe occurred about 560 million years after the Big Bang.

June 25, 2014 Recent results cast doubt on claims that a much-hyped experiment has detected signals from the Big Bang itself. That's just another example of science in the making, says commentator Marcelo Gleiser.
Cosmic microwave background radiation (CMB) as observed by Planck. The CMB is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380,000 years old.
April 16, 2013 Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because science faces a fundamental problem when it can't agree on numbers like the value of the Hubble Constant. The whole point of science is to establish an understanding of the cosmos on which we can all agree.
Science has been working to shed light on the nature of the Universe for 400 years.
April 10, 2013 Science discovers one dark material after another, making reality stranger than fiction. Commentator Marcelo Gleiser says the recent observation of the Higgs field and last week's announcement of the possible detection of dark matter are just the latest data points in our long quest to know what the Universe is made of.

March 21, 2013 Results from the European Planck satellite point to an older and slower universe. Commentator Marcelo Gleiser says the data gives us confidence that cosmology is on the right track to explain the Universe in which we live.
