RF2D8K7X8–Active Sun artwork. Solar flares are seen leaping from the Sun's surface. These are loops of plasma (charged gas) which are ejected from the surface and follow magnetic field lines before hitting the surface again. Several sunspots (dark) are also seen on the Sun. These are cooler areas of gas
RF2GG0CK7–Jupiter seen from the surface of volcanic moon Io. Io, the innermost of the Jovian Galilean moons, orbits so close to Jupiter that its interior is kept molten by the giant planet's tides. The heat from the interior makes Io the most volcanically active world in the known Solar System. Jupiter is seen in the sky, top right, with the Sun remerging from behind it
RF2C0XE7R–Enceladus is a mid-sized satellite of Saturn, about 500 km across, known since 1789. It is only one-tenth the size of the largest Saturnian moon, Titan. In 2005, the Cassini spacecraft discovered that this relatively small world is, surprisingly, geologically active. Geyser-like jets of water were seen venting from the moon's south-polar surface ices, vented by a process called cyrovolcanism ('cold volcanism'). Another satellite, Mimas, is seen on Saturn's ring plane.
RF2GG0CM6–Jupiter seen from the surface of volcanic moon Io. Io, the innermost of the Jovian Galilean moons, orbits so close to Jupiter that its interior is kept molten by the giant planets tides. The heat from the interior makes Io the most volcanically active world in the known Solar System. Jupiter is seen in the sky, top right. On the far left and right, respectively, can be seen the Galilean moons Callisto and Ganymede. Europa, not in in the scene, is casting its shadow on Jupiter.

RFMC8DEY–Illustration showing jets emanating from the poles of a young star. A dark circumstellar disc of dust is seen nearly edge-on across centre. Discs such as this are thought to be the precursors of planetary systems, with planets forming as the dust coalesces. The jets (bipolar molecular outflows) are thought to form as material ejected from the star is forced into two jets by the rotation of the disc.
RFM6CXC2–The Sun as a red giant. Earth begins to melt as the red-giant Sun swells and approaches our planet's orbit. Eventually the melting may penetrate throughout Earth's crust, leaving the planet molten from surface to core. The fate of the Earth is unclear. It may become engulfed by the Sun, or it may move to a safe orbit as the Sun sheds mass at the end of its life.

RFP8YC7P–Illustration of a coronal mass ejection (CME) emanating from the Sun. These events are powerful releases of solar charged particles (plasma) and magnetic field, travelling on the solar wind. When a CME hits Earth, it can cause a geomagnetic storm which disrupts the planet’s magnetosphere, our radio transmissions and electrical power lines. They can damage artificial satellites and cause long-lasting power outages. Humans in orbit are also very vulnerable to these events, whose high-energy particles are not shield by typical spacecraft.
