Who first studied the stars?
Galileo Galilei was among the first to use a telescope to observe the sky, and after constructing a 20x refractor telescope.

Who was a famous astronomer and scientist of the ancient period?
In ancient Greece, astronomer and mathematician Claudius Ptolemy (A.D. 90–168) set up a model of the solar system in which the sun, stars, and other planets revolved around Earth. Known as the Ptolemaic system, it remained in place for hundreds of years, though it turned out to be flat wrong.
What qualifications do you need to be a space scientist?
To become a space scientist, one should possess relevant education in pure science or engineering disciplines. ISRO recruit candidates with PhD in Astronomy, Physics and Mathematics along with engineers in disciplines such as mechanical, electrical, electronics and computer science.
How long does it take to get a PhD in astronomy?
Most astronomy positions require a PhD degree, which can take five or six years of graduate work.
What space scientists do?
What Does a Space Scientist Do? A space scientist studies the properties of outer space, including our solar system and other galaxies and solar systems, by analyzing data collected by equipment mounted on orbiters, satellites and other probes that are sent into space.
What science is space?
Scientific research in space can be divided into five general areas: (1) solar and space physics, including study of the magnetic and electromagnetic fields in space and the various energetic particles also present, with particular attention to their interactions with Earth, (2) exploration of the planets, moons.
What is space easy?
Space, also known as outer space, is the near-vacuum between celestial bodies. It is where everything (all of the planets, stars, galaxies and other objects) is found. This is where Earth’s atmosphere is said to stop and outer space begins.
How is space formed?
Around 13.8 billion years ago, all the matter in the Universe emerged from a single, minute point, or singularity, in a violent burst. This expanded at an astonishingly high rate and temperature, doubling in size every 10-34 seconds, creating space as it rapidly inflated.
How does space exploration affect science?
Scientific research founded on data from space is also leading to discoveries with benefits for life on Earth. Ongoing research in the space environment of the ISS – in areas such as human physiology, plant biology, materials science, and fundamental physics – continues to yield insights that benefit society.
Why is space travel so important?
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
Why we should keep exploring space?
Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.
What should be done for economical use of space?
Executive Summary
- tapping space-based clean energy sources.
- mining asteroids for useful raw materials.
- developing safe venues for scientific experiments.
- upcycling/sequestering hazardous but valuable debris currently in space.
- tapping sources of water already in space, to decouple into oxygen and hydrogen for.
What will happen in space in 2020?
In 2020, private companies will continue to develop low-cost internet from space by launching large constellations of satellites. SpaceX plans to have Starlink operational with more than 700 small satellites in low-earth orbit by the end of 2020, launched in batches of 60 satellites.
How long are they going to be in space 2020?
seven years
