Stars formed in the early Universe were extremely massive and extremely low in elements heavier than helium. The transition from the first to the second generation of stars is still hidden in the shadows of the past. However, simulations of the most massive supernovae can help us to decipher the way of how the life cycle of stars came into being.
Observations of dust near the remains of a supernova in the center of our galaxy could have implications for dust production in the earliest galaxies.
How can we measure the temperature of the Universe across cosmic epochs? Recent data from Planck suggests that the Universe’s cooling history is consistent with the Big Bang model.
Thought dust could only bore you? Think again: it may obscure our view of time’s very beginning!
Much like the Cosmic Microwave Background, the Cosmic Neutrino Background permeates our Universe and it could take us back to 1 second after the Big Bang. Today, we discuss the effect of the Sun on modulating the expected signal from the neutrino background.
BICEP2 results show a 5.3 sigma detection of gravitational waves from inflation’s imprint on the cosmic microwave background (CMB).
