Humanity has been wondering for a long time: "Are we alone in the Universe"? Is there a mind in its vast expanses, born under a different sun and looking at completely different stars in the night sky? On April 18, 2018, the TESS space telescope was launched on a Falcon 9 launch vehicle to search for exoplanets, that is, planets outside the solar system. Almost four years have passed since then. What was discovered during this time? Are we any closer to answering one of humanity's most burning, intriguing questions - is there extraterrestrial life? Are we alone in the universe?

In an incredible first, astronomers have discovered what lies at the core of Mars. It turns out, the Red Planet isn't as lifeless as we once thought. Mars wasn't always a dusty, barren world. There's plenty of evidence that the planet was warm, had lakes of liquid water, and was habitable for a short period in its history. Astronomers had always wanted to know the reason behind this transition, and for that, they had to know what lies at the core of Mars. When the InSight lander started studying the planet's interior, it discovered that the planet is still rumbling with seismic activity. Now, following a rigorous half-decade mission, InSight has granted scientists a clear vision of the Martian core. So, how does Mars' core differ from Earth's? What methods did InSight employ to unveil the core of the Red Planet? Finally, and most importantly, what does it tell us about the future of our planet? The 1st episode of the Sunday Discovery Series
