Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
In June 1770, the explorer James Cook ran aground on the Great Barrier Reef in Australia and became the first European to experience the world's largest coral reef, today a paradise for scientists and holidaymakers alike. Last year, the James Cook research vessel set out to encounter unique and unexplored corals, this time in the deep ocean. Led by ERC grantee Dr Laura Robinson (University of Bristol, UK), the team on board crossed the equatorial Atlantic to take samples of deep-sea corals, reaching depths of thousands of meters. On the expedition, Dr Robinson collected samples that are shedding light on past climate changes and she will share her findings at TEDx Brussels.
