New exoplanets discovered during light dimming observation

Astronomers have found more than three thousand new exoplanets, nearly all are middle-aged with ages of a billion years or more.
There is a huge process for astronomers to study the life cycle of the planetary system this is like using the current example on how baby grow to adults.
Now, a team of Caltech-led researchers has discovered the youngest fully-formed new exoplanets ever detected. The planet, K2-33b, at 5 to 10 million years old, is still in its infancy.
The first signals of the planet's existence were measured by NASA's Kepler space telescope during its K2 mission.
The periodic dimming of the lights from the planet host star called K2-33 hinted the existence of an orbiting planet.
After this, they observed it from the Hawaii and came to a conclusion that the planet around it is causing the dimming of the light.
"At 4.5 billion years old, the Earth is a middle-aged planet-about 45 in human years," says Trevor David, the first author on the paper and a graduate student working with professor of astronomy Lynne Hillenbrand.
This discovery is a great achievement in the new exoplanets science, this will help the researchers know how the newborn planets form.
When stars form, they are encircled by dense regions of gas and dust, called protoplanetary disks, from which planets form.
After this observation, there were many new exoplanets found which were discovered due to the dimming of the light.
The exoplanet, which is about six times the size of Earth, or about 50 percent larger than Neptune, makes a complete orbit around its host star in about five days. This implies that it is 20 times closer to its star than Earth is to the Sun.
This is just the start and this will lead to much more findings and there is much more to learn.
