Scientists saw gravitational waves for the first time in 2015, caused by the collision of two black holes billions of light-years apart. This confirmation of Einstein’s general theory of relativity created a new window for watching and analysing the world, providing a one-of-a-kind means to explore the universe and acquire insights into the nature of gravity itself.
5. Homo Naledi: The Discovery of a New Human Ancestor
Archaeologists discovered a new species of hominid dubbed Homo naledi deep beneath South Africa’s Rising Star Cave system in 2013. This early human progenitor, with its unusual blend of primitive and current traits, called into question our concept of human evolution. The discovery was notable not just for its scientific value, but also for the sheer volume of fossil remains recovered — over 1,550 skeleton fragments from at least 15 people. The discovery of Homo naledi provided insight on the complexities of our evolutionary history and the variety of our ancestors.
6. The Exoplanet Proxima b: A Potential Earth-Like World
Astronomers discovered an exoplanet circling Proxima Centauri, the nearest known star to our solar system, in 2016. This planet, known as Proxima b, is around 1.3 times the size of Earth and is located within the habitable zone of its star. Although much remains unknown about Proxima b, its close connection to Earth and the possibility of liquid water make it an enticing target for future study and the hunt for alien life. The discovery of Proxima b is an important step towards understanding the prevalence of possibly habitable worlds in our cosmic neighbourhood.
7. The Deep Sea Mystery: Exploring the Mariana Trench
The Mariana Trench, located in the western Pacific Ocean, is the deepest region of the Earth’s seas known to man. James Cameron, a filmmaker and adventurer, performed a record-breaking solo dive to the trench’s depths in 2012, reaching an astounding depth of 35,787 feet (10,908 metres). This incredible effort provides crucial insights into the deep sea’s severe conditions and distinct habitats. Subsequent expeditions and technological advances have continued to reveal the astounding diversity of life and geological formations surviving in our planet’s darkest and most distant regions.
8. First Image of a Black Hole: A Monumental Astrophysical Achievement
The Event Horizon Telescope (EHT) collaboration announced the first-ever direct photograph of a black hole in April 2019. The picture depicted the supermassive black hole in the heart of the galaxy Messier 87, which is 55 million light-years from Earth. The photograph revealed an illuminating ring of light, known as the black hole’s event horizon, surrounding the black hole’s shadow in darkness. This landmark accomplishment offered visible proof of the existence of black holes, validating Einstein’s general theory of relativity predictions and opening up new possibilities for research into these mysterious cosmic phenomena.
Aside from visual confirmation, the first sight of a black hole opened up a world of new scientific possibilities and inquiries. Scientists were able to thoroughly examine the obtained picture, revealing detailed traits and behaviours linked with these cosmic creatures.
The image’s dazzling ring of light, created by tremendous gravitational forces bending and trapping photons, revealed important details about the behaviour of matter and energy around the event horizon. It revealed the presence of an extreme gravitational field capable of bending light and space itself, correlating with Einstein’s general theory of relativity.
Furthermore, this major accomplishment set the path for further research into the physics of black holes. Scientists now have a clear starting point for investigating the dynamics of black hole accretion discs, the production and ejection of relativistic jets, and the interaction of matter with black hole gravitational fields.
The EHT project’s success also demonstrated the value of international collaboration and technical development. A global network of telescopes was used in the effort to build a virtual Earth-sized telescope capable of catching the elusive image. To overcome the problems given by huge data quantities and the influence of Earth’s atmosphere, breakthrough algorithms and data processing approaches were required.
The first look of a black hole not only captivated scientists but also sparked popular interest. It served as a reminder of the tremendous mysteries that surround us in the universe, as well as the limitless possibilities for discovery. This incredible feat has inspired a new generation of academics and astronomers, powering further advances in our knowledge of black holes, gravity, and the inner workings of our universe.
