Aurora
It is believed that the aurora phenomenon may occur on all other extrasolar planets that have a magnetic field and a magnetosphere exposed to stellar winds.
The resolution of the telescopes does not make it possible to capture an image of this phenomenon, but the emission of radio waves accompanying the aurora can be detected using radio telescopes.
lava
The temperature of lava, depending on its composition, can range from 700 to 1,200 °C.
Beyond Earth, lava can reach even higher temperatures; the record holder is Io, Jupiter's moon, where satellites have recorded lava flows with an average temperature of 1,300 °C (2,370 °F).
NASA
After the Space Shuttle Columbia disaster, the construction of the ISS was paused until the launch of Space Shuttle Discovery on July 26th, 2005.
Milky Way
Its diameter is from 100 to 120 thousand light years.
It is therefore a relatively large galaxy, although some cosmic giants may dwarf it in size. IC 1101 is about 20 times larger than the Milky Way, with a diameter of 2 million light-years.
Amber
It has been used as a gemstone since antiquity.
Once polished, it glistens and resembles a gemstone.
Phobos
The largest impact crater on the surface of Phobos is called Stickney, its diameter is up to 10 kilometers.
It was named after Asaph Hall’s wife, Chloe Angeline Stickney Hall, a mathematician. A collision that formed Stickney crater could have shattered the moon.

Especially common for women, it is a result of hormonal changes after menopause.
