radiowaves
Grote Reber, not Grote Weber, is credited with building the first radio telescope in 1937. He used a parabolic antenna to observe radio waves from outer space, laying the foundation for modern radio astronomy.
Scientists discovered that the outer core of the Earth is liquid by studying seismic waves generated by earthquakes. They observed that S waves do not travel through the outer core, indicating that it is liquid, while P waves do, suggesting that the inner core is solid. This finding led to the understanding of the Earth's layered structure.
Beno Gutenberg, a prominent seismologist, contributed to the understanding of the Earth's outer core through his analysis of seismic wave behavior. In the early 20th century, he studied how seismic waves generated by earthquakes traveled through the Earth. He observed that certain seismic waves, specifically S-waves (shear waves), could not pass through the outer core, indicating that it was liquid. This observation, combined with the differing behavior of P-waves (compressional waves), led to the conclusion that the outer core is composed of molten material.
The purpose of Voyager 2's flyby of Neptune in 1989 was to study the planet's atmosphere, magnetic field, and moons. It provided valuable data and close-up images of Neptune and its moons, expanding our understanding of the outer solar system.
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
Karl Jansky did not have any children. He was a pioneering physicist and engineer known for his work in radio astronomy, particularly the discovery of radio waves from outer space.
Sally Ride did not make any specific scientific discoveries during her time in outer space. She was the first American woman to travel to space as an astronaut aboard the Space Shuttle Challenger in 1983. Ride conducted various experiments related to physics, materials science, and Earth observations during her mission.
It was made to discover the secrets of outer space.

Alan Shepard was the first and second American to go to outer space.
Outer space was not discovered by a single person, as it has always existed. However, the first human to travel to outer space was Yuri Gagarin, a Soviet astronaut, who orbited Earth in 1961.
He's a mechanical engineer at Cal Tech, specializaing in gear used in outer space.
Alan Shepard
Telescopes have helped discover many things in space that are not visible such as some of the outer planets of our solar system.
