What is the primary function of the Spitzer telescope?
Mission Overview The Spitzer Space Telescope, formerly known as the Space Infrared Telescope Facility, is an infrared telescope that studies the early universe, young galaxies and forming stars, and is used to detect dust disks around stars, considered an important signpost of planetary formation.
What did Spitzer Space Telescope discover?
In 2007, astronomers using the Spitzer Space Telescope announced that they had found water in the atmosphere of the exoplanet HD 209458b — work that has been confirmed by observatories such as the Hubble Space Telescope. The Jupiter-size planet orbits very close to its star, giving it the name “hot Jupiter.”
What does the Spitzer Space Telescope measure?
What is Spitzer Space Telescope? NASA’s Spitzer was the first telescope to detect light from an exoplanet, or a planet outside our solar system. Spitzer uses an ultra-sensitive infrared telescope to study asteroids, comets, planets and distant galaxies.
How does the Spitzer Space Telescope work?
1. A basic external view of Spitzer in its Earth-trailing solar orbit. The telescope cools by radiating to space and by the change in enthalpy of evaporating liquid helium while hiding from the Sun behind its solar panel and flying away from the thermal emission of the Earth.

Is the Spitzer telescope still in space?
The Spitzer Space Telescope, formerly the Space Infrared Telescope Facility (SIRTF), is a retired infrared space telescope launched in 2003 and retired on 30 January 2020.
Are there more planets than stars in our galaxy?
Other Solar Systems Our Milky Way Galaxy is just one of billions of galaxies in the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it. This means there are potentially thousands of planetary systems like our solar system within the galaxy!
Are there free floating planets?
Scientists have seen evidence of a mysterious set of “free-floating” planets, making their way through deep space without being attached to any star. The research was done using Nasa’s Kepler Space Telescope, which captured intriguing signals that suggested there are Earth-sized planets hiding within space.
How many planets are in our galaxy 2020?
“As many as six billion Earth-like planets in our galaxy, according to new estimates.” ScienceDaily. ScienceDaily, 16 June 2020.
What is the most successful way to discover exoplanets?
transit method
Whats the fastest we can travel in space?
We believe in the free flow of information The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.
