SOLAR SYSTEM

Detailed explanation-1: -Spectrographs. Hubble’s Space Telescope Imaging Spectrograph (STIS) captured a spectrum (right) of material ejected by a pair of massive stars called Eta Carinae, while the Wide Field and Planetary Camera 2 took an image of the billowing clouds of gas enveloping the stellar pair (left).

Detailed explanation-2: -Hubble is solar-powered. Hubble takes sharp pictures of objects in the sky such as planets, stars and galaxies. Hubble has made more than one million observations.

Detailed explanation-3: -Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.

Detailed explanation-4: -To see this invisible electromagnetic radiation, we need to use special tools like microwave telescopes and gamma-ray telescopes. A visible light photo of the Milky Way galaxy.

Detailed explanation-5: -A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky.

Detailed explanation-6: -The Hubble Space Telescope took this picture of the Tadpole Galaxy and its tail of large, bright blue star clusters. The “Hubble Ultra Deep Field” shows many galaxies far from Earth.

Detailed explanation-7: -Radio telescopes, telescopes detecting infrared radiation, gamma rays, and X-rays and space-based telescopes are essential in modern astronomy.
