THE LONG MARCH 5B ROCKET
THE LONG MARCH 5B ROCKET
BIG CHINESE ROCKET SEGMENT FALL TO EARTH
The Long March 5B, a huge rocket of 18 tonnes and 30 metres high, was launched on April 29th. Its mission was to carry into orbit a module containing living quarters for a future Chinese space station.
Experts pointed out that the rocket was going to land somewhere on the Earth after they had lost control of it. However, according to calculations based on observations and mathematical models, the rocket debris could impact somewhere between the 41st parallel north and south. And most likely in the waters of the Atlantic Ocean, followed by the Pacific and Indian Oceans. It is true that in this area is located a part of Europe and specifically Spain, and the probability of falling in our country has increased by 50%, but it is still very low.
Finally, after some days, on May 9th, the impact site is located close to the Maldives, just south of the Indian subcontinent in the Indian Ocean. Most of the vehicle had been burned up when it made its final plunge through the atmosphere, although metals with high melting points and other resistant materials have survived to the surface.

The oldest fossils ever found
The oldest fossils ever found
One of the questions we human beings have wondered the most is the one about when life on the Earth started. Little by little, proofs have been discovered, and we have known a bit more about our history. Recently, an incredibly important discovery has been carried out: the oldest fossil in the world has been found.
Some years ago, in the 80's, a group of 3.5 billion-year-old fossils were detected in the Australian desert, thought to be the oldest fossils ever found. However, in 2016, that idea was demolished. Thanks to metamorphic stones in the south of Greenland, we have known the very first evidence of earlier life on Earth.
They were 3.7 billion-year-old stromatolites, much older than the Australian fossils. Even so, there didn't seem to be any conclusive proof of organic life in them, so they weren’t recognized as that. Nevertheless, after many researches and experiments, scientifics could finally find nitrogen-bearing organic material, as well as strands and filaments of organic matter that closely look like the remains of biofilms formed by microbe colonies, and they could, at last, confirm the rocks as the oldest fossils ever found.
Bit by bit, we are making scientific progress and been able to answer many questions we have been wondered for a long time. Sometimes there are any misunderstandings, or it takes time to reach the proof to verify a belief, but we must continue investigating and working to know a bit more about ourselves.
