With the current state of climate change becoming more and more complex, environmental disasters occur continuously, natural resources are exhausted and the population is growing rapidly on the earth as today, finding a new planet life to prepare for a future 'home-shift' is no longer the only idea that exists in science fiction movies.
NASA is the first organization to express its ambition to realize this idea. The US space agency recently proposed a plan to launch a state-of-the-art space telescope into space to do so. This telescope, called the Habitable Exoplanet Observatory (HabEx), takes on its responsibility to search for a second Earth, where humanity can move to in the future.
'Our goal is to see if modern technology can help us find a planet similar to Earth - a possessive planet eligible for life. Although we have found many planets accessible outside the solar system, to date, none of the planets have been identified with the necessary elements for human habitation. ' , said Professor Scott Gaudi, a researcher from Ohio State University.
HabEx is a new space telescope model developed by NASA, similar to the Hubble Space Telescope, but equipped with a much larger lens with a width of 4m (compared to Hubble's 2.4m). HabEx will also be equipped with a radiation shield according to the origami philosophy - a 52-meter-wide disc will be folded into a tight spiral, which can be ejected into a flower shape. This device is responsible for blocking light, solar radiation from nearby stars, allowing the telescope to detect weak light emitted from more distant stars, providing greater insight into the air. space.
The HabEx project is divided into 3 phases with 3 clear goals.
- Stage 1: Search for nearby planets.
- Stage 2: Draw out diagrams of nearby planetary systems and clusters and search for each individual planet in it.
- Stage 3: Discover the far reaches of the universe.
