Hale-Bopp was a comet that was visible in the night sky in 1997. It had a very bright tail and was visible for 18 months.

The Perseids are a meteor shower that occurs every year in August. They are caused by the debris from the comet Swift-Tuttle.

Curiosity is a spacecraft that landed on Mars in 2012. It is a car-sized rover that is exploring the surface of Mars and searching for signs of past or present life.

Juno is a spacecraft that is currently orbiting Jupiter. It is studying the planet's interior, atmosphere, and magnetic field.

New Horizons is a spacecraft that is currently exploring the outer solar system. It flew by Pluto in 2015 and is now on its way to the Kuiper Belt.

The Very Large Telescope is located in Chile and is the largest optical telescope in the world. It consists of four 8.2-meter telescopes that can be used together to create a single image with a resolution that is 10 times better than the Hubble Space Telescope.

The James Webb Space Telescope is located in space and is studying the early universe. It is the most powerful and expensive space telescope ever built.
