Sometimes the expository texts can have an index, theoretical framework, bibliography or annexes.

Characteristics of the expository texts

The main features of the expository texts are the following:

• Explain or inform on a topic, in order to make it known, clarify or describe it.
• They tackle a precise and delimited subject in an orderly manner.
• Make use of different resources, such as explanations, classifications, descriptions, exemplifications and quotes.

The Goths and the problem of the barbarian invasions

Throughout the 4th century, incursions into the Roman Empire by foreign peoples became more and more frequent. These had been called by the Latin writers by the name of barbarii, that is, foreigners, a denomination applicable, consequently, to all those people settled beyond the limex. The phenomenon was far from new. Since the end of the second century BC. C., the Romans had annihilated Cimbrios and Teutones, ending in this way with the barbarian danger to the north. Raids — or the peaceful settlement — of Germans into Empire lands had been a relatively frequent occurrence. What again presented these penetrations of barbarian peoples in the fourth century was, on the one hand, their frequency, and, on the other, the increasingly manifest impotence of the Western Roman Empire to repel them.

At the base of all this process was the socio-economic crisis that, since the third century, the Roman world had been suffering. Indeed, since that century the decline of the cottage industry in the western half of the Empire, victim of oriental competition, it is evident and it translates into the ruin of the artisan life of many cities.

A NASA telescope discovers a solar system with seven planets like Earth

A cold dwarf star 40 light-years away is home to a planetary system that could support life.

An international team of astronomers has discovered a new solar system with seven planets the size of Earth. It is about 40 light years from us, around a faint, cool star of a type known as "red dwarfs." In the Milky Way, this class of stars are much more abundant than stars like the Sun and, recently, they have become the place favorite to search for terrestrial twins that could harbor life, as explained by researchers and NASA officials in a wheel of press. "The question now is not if we will find a planet like Earth, but when," they have assured.

The new solar system orbits Trappist-1, a Jupiter-sized star located in the constellation Aquarius. Last year, an international team of astronomers found three planets orbiting this star, with only 8% of the mass of the Sun. In a new study published today in the journal Nature, the same team confirms the existence of these three worlds and announces another four. All are similar in size to Earth, but they are much closer to their faint star, which would allow them to harbor liquid water, an essential condition for life. It is the solar system with more planets the size of the Earth and that could contain water that has been found to date, according to a statement from the European Southern Observatory (ESO).

In February and March 2016, astronomers used the NASA Spitzer Space Telescope to capture the tiny fluctuations in the star's light that occur when planets pass in front of their star. Spotting scopes in Chile, South Africa, Morocco, the US and the Canary Island of La Palma, also pointed their lenses at Trappist-1 between May and September. The observations confirm the existence of six planets, Trappist-1 b, c, d, e, f and g, according to their decreasing proximity to the star, and suggest the existence of a seventh, h, not yet confirmed. All six confirmed planets appear to be rocky, like Earth, Mars, Venus, and Mercury, although some could be much less dense. Trappist-1 and its worlds closely resemble Jupiter and its icy moons Io, Europa, Ganymede, and Callisto, some also candidates for life.

"It is an amazing planetary system, not only because there are so many but because their size is surprisingly similar to the Earth ”, says Michaël Gillon, researcher at the University of Liège (Belgium) and main author of the study. "The question of whether we are alone in the universe will be resolved in the coming decades," said Thomas Zurbuchen, a NASA researcher, during the press conference. It will not be traveling, or at least for now: to get there with current technology, we would need about 300,000 years.
