Scientists explore the solar system through various methods and technologies. These include space probes, telescopes, and robotic missions. Space probes, such as Voyager and New Horizons, are sent to different planets and moons to gather data and images. Telescopes, both on Earth and in space, help scientists observe and study distant objects in the solar system. Robotic missions, like the Mars rovers, allow scientists to explore the surface of other planets and search for signs of life. These exploration methods provide valuable information about the planets, moons, and other celestial bodies in our solar system, expanding our knowledge of the universe.
Have you ever gazed up at the shining stars in the night sky? Have you ever pondered what lies beyond? Of course, your educators have educated you that there are stars, planets, and entire galaxies in the vast expanse of the universe.
But how do we come to know all this? Although humans have set foot on the Moon, in the grand scheme of the universe, the Moon is relatively close to Earth. After all, there are other moons and planets that are millions of lightyears away. So, how do scientists investigate the farthest reaches of space?
Technology plays a crucial role in enabling us to explore beyond our own planet. Various instruments have assisted experts in peering into our galaxy and beyond. One of the initial tools for space exploration was the telescope, which provided scientists with their first glimpse of what lies beyond Earth’s atmosphere. Telescopes employ lenses and mirrors to extend our vision beyond the confines of our planet.
Significant discoveries were made with telescopes, paving the way for further space exploration. Humans have embarked on journeys to the Moon and countless space shuttle missions. They have ventured into space and conducted research on a wide range of scientific subjects.
Scientists have always been driven by curiosity. As our knowledge of outer space expands, we realize just how much more there is to explore. Consequently, experts have developed even more advanced tools that allow us to explore places beyond the reach of human exploration.
For instance, the telescope is no longer limited to Earth. In 1990, the Hubble Space Telescope was launched into outer space, where it has remained for over three decades. It has captured images of our universe that would have been impossible to obtain otherwise.
The Hubble Telescope is an astonishing feat of technology, powered by sunlight. It is equipped with multiple cameras and scientific instruments. This telescope has provided scientists with invaluable data, which NASA reports has been utilized in over 17,000 scientific papers!
Since the late 2000s, scientists have also conducted numerous experiments in low-Earth orbit, thanks to the International Space Station (ISS). As the first orbital space station intended for long-term visits from astronauts from various countries, the ISS is seen as a stepping stone towards sending humans on missions to Mars and beyond.
Meanwhile, scientists have continued to forge ahead, constructing numerous machines to explore the deepest corners of our solar system. Probes, such as NASA’s Cassini probe, have been dispatched to investigate other planets. If you have recently marveled at a breathtaking image of Saturn, you have the Cassini probe to thank.
Astronomers have always been fascinated by Mars. Presently, we possess more knowledge about the red planet than ever before. The Mars Reconnaissance Orbiter and the Mars rovers, Spirit, Opportunity, and Curiosity, are formidable robots that have greatly contributed to our understanding of Martian geology.
As time progresses, scientists will continue to expand our knowledge of the universe, utilizing advanced scientific technology. Thanks to the Kepler telescope, launched in 2009, we now know that there may be over 3,000 planets orbiting more than 2,000 stars in the Milky Way galaxy. All of these discoveries were made possible by Kepler!
