Which of these statements about the Sun are true?
It has a radius of 700 000 km.
Its mass is more than 98% the mass of the whole Solar System.
Its state of matter is solid
It is at the end of its stellar life.
In 5000 million years, it will evolve to a red giant, occupying the current Earth-Sun distance.
Opposite to the Earth, hydrogen and helium are the most abundant chemical components in it.
It has several internal and external shells, with different properties.

What do you know about the European Space Agency?
It is a travel Agency for Europe
It is formed by 22 countries
It has several social media channels to communicate to the public the latest discoveries, like the
It has a scientific fleet of more than 20 satellites studying the solar system and the cosmos
It has several positions focused on develop our knowledge about the Universe (engineers, scientist, lawyers, educators, ...)

How much time would the trip of Solar Orbiter, from the Earth to the Sun, last?
6 months, if the spacecraft were flying at a constant speed of 30 000 km/h
more than 3 years, in order to end up orbiting the Sun and not falling into it
more than a year, because for not carrying that much fuel, gravity assist manoeuvres are required
many years, because during the manouvers around Venus or the Earth it could land in any of these planets

The magnetic activity in the Sun is responsible of
the appearance of sunspots
the generation of solar mass ejections
the sun rotation
erupting prominences
aurora borealis
solar eclipses
Earth climate change
3 points
Coronal mass ejections
are detected in the layer of the Sun called
are composed by solar plasma and magnetic fields, ejected to the Solar System as part of strong solar eruptions
are detected quite often during periods of high-rate of solar activity.
are only detected from satellites, like SOHO and Solar Orbiter
1 points
The ESA/NASA space mission, SOHO, is capable to detect a solar storm arriving to Earth
a year in advance of arriving to the Earth
days in advance of arriving to the Earth
hours in advance of arriving to the Earth
5 points
Sunspots
rotate at the same speed on the whole sun surface
are more visible when the Sun has a high-rate of magnetic activity, every 11 years
rotate faster at the solar equator than at the poles
could be as big as the size of Earth or Jupiter
are caused by plasma that pass through the solar surface in and out, following the magnetic lines.
could be observed from the HELIOS ground-telescope, that belongs to the CESAR Team
are darker because they are at higher temperature than the sun surface (at 5 600 K).

What are the goals of the latest ESA mission to the Sun, Solar Orbiter, launch in February 2020?
To become very close to the Sun to understand how the inner heliosphere works and varies
To analyse the solar poles, to better understand the solar dynamo
To land on a sunspots
5 points
The HELIOS ground-based telescope ...
belongs to the CESAR Team and is installed at ESAC
takes pictures of the Sun in the visible and H-alpha filters
use its scientific data to create CESAR Educational Resources
is able to detect sunspots and eruptive prominences
has the same properties as the CESAR telescope used to observe the solar eclipses all around the world
