Aurora Borealis, as seen from South Dakota -- At the North and South Magnetic Poles of our planet Earth, we see the sky light up, flash and shimmer. We call this effect an aurora. In the northern hemisphere it is called the Aurora borealis, also known as the "Northern Lights". In the southern hemisphere, it is called Aurora australis, also known as the "Southern Lights".

Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

Jupiter's moon Ganymede is the largest satellite in the solar system. Larger than Mercury and Pluto, and only slightly smaller than Mars, it would easily be classified as a planet if were orbiting the sun rather than Jupiter.

The moon likely has a salty ocean underneath its icy surface, making it a potential location for life. The European Space Agency plans a mission to Jupiter's icy moons that in 2030, is planned to arrive and put special emphasis on observing Ganymede.

The Roman theatre of ancient Arausio (modern day Orange in southern France) is one of the best-preserved examples from antiquity. Built in the 1st century CE, it once had capacity for 9,000 spectators and is dominated by its massive stage wall with an ornate façade decorated with columns, doorways, and niches. The theatre was listed as a UNESCO World Heritage Site in 1981 CE.

Ferrofluid and Magnets

Ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. It is typically composed of ferromagnetic (iron) particles suspended in oil. When exposed to a magnet, the particles align with the surrounding magnetic field. The complex orientation of the ferrofluid reveals the magnetic field around the two magnets.
