Social Media Lead: Flares are often linked to eruptions, called coronal mass ejections (CMEs), which hurl massive clouds of magnetized plasma far into space, plowing right through the continuous flow of charged particles that normally stream from the Sun, called solar wind, and can reach Earth in up to three days. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. According to the Index of Objects Launched into Outer Space, maintained by the United Nations Office for Outer Space Affairs (UNOOSA), there were 5 774 individual satellites in space at the end of March this year; an increase of 15.78% compared to the start of 2019. The combination of increasing numbers of new satellites and the growing amount of orbital junk leads to a perilous situation that in the not-so-distant future may turn some regions of near-Earth space into a dangerous no-go zone. Although the Sun may look like a constant ball of light every day, it actually goes through a cycle of increasing and decreasing activity that lasts around 11 years. For example, Earth is a satellite because it orbits the sun. Originally from Prague, the Czech Republic, she spent the first seven years of her career working as a reporter, script-writer and presenter for various TV programmes of the Czech Public Service Television.

We can see manifestations of the Sun's magnetic field in the form of active regions, which appear at the Suns surface as cooler, dark areas, and in SUVI observations of the Suns corona as bright concentrations of loops. Many planets have moons, and some planets have many moons - Saturn has more than 50, whereas Mars has just two. The flare produced aurora (northern lights) that were visible across Canada and, Pennsylvania, Iowa, and Oregon. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
