A few years ago, the Hubble Space Telescope did something amazing: over the course of 841 orbits and hundreds of exposures, it imaged a tiny region of space in the constellation of Fornax, peeling back the layers of time by 13 billion years, to just a few hundred million years after the Big Bang.
One of the scientists involved in the study pointed out that although the number of space rocks striking earth is increasing, the probability of an asteroid strike wiping out mankind is extremely low.
Planetary researchers believe that our Moon was created more than 4.4 billion years ago in a catastrophic collision between proto-Earth and a hypothetical planet-sized body known as Theia. According to new research, our planet received the bulk of its carbon, nitrogen, sulfur and other life-essential elements from that planetary collision.
Prof Clive Finlayson, director of the Gibraltar Museum, explains why some old assumptions about the intellectual capabilities of our evolutionary relatives, the Neanderthals persist today. But a body of evidence is increasingly forcing us to re-visit these old ideas.
