Ancient Earth: Birth of the Sky Wed, Oct 4, 2023 Early Earth was a hellscape of molten lava and barren rock, bombarded by meteors, with no atmosphere at all. How did our familiar blue sky - the thin, life-giving band of gasses protecting our planet - come to be? Where to Watch ...
(Cesarsky et al., 1996), the camera on board of ISO; these observations reveal the spatial distribution of the silicate knots and of the neon knots. The comparison of these distributions reveals unique information on the degree of mixing of the various elements which has occurred during the ...

The Bay of Fundy Tides is a day-long experience on the tour. This unique seascape is home to the tallest tides on planet Earth, and your stay at the sophisticated Chateau Moncton offers a sublime view of the Petitcodiac River’s tidal bore. Cross The Bridge to Prince Edward Island The...
Since this remnant fell into the mud at the bottom of a sea millions of years of new forms superceded older forms, each composed of matter on earth’s surface. But does time exist? No, only leftover impressions in matter exist to give us the illusion of the past. It’s always “now...

1. Introduction Stars and binary stellar systems massive enough end their lives in collapses releasing a large amount of energy; these phenomena are called "supernovae". A supernova close enough to the Earth is a spectacular event: it can appear as a "new star" as luminous as Venus, or ...
A supernova close enough to the Earth is a spectacular event: it can appear as a “new star” as luminous as Venus, or even more, visible for several days. The rate of Galactic supernovae is expected to be of about one in 30 years, with a fraction visible to the naked eye; howeve...
his team began working to understand the physics of that merger before their simulations pointed toward collapsars as a heavy element birth chamber. "Our research on neutron star mergers has led us to believe that the birth of black holes in a very different type of stellar explosion might pro...
