We, of the Mega Curioso, have already spoken here about the formation of the Solar System and its planets, including ours (spherical!). You can check the entire story through this link, but fundamentally according to the most accepted theories – after all, no one was there to see how things unfolded – our "little corner" in the galaxy has been formed billions of years ago. a cloud of gas and cosmic dust whose particles gradually became denser and denser.

So these regions of higher density would collapse under gravity itself and, little by little, attracting more and more of matter – until everything is compact and gives birth to the Sun. Thus, the nuclear reactions that occurred in the "newborn" star led to the emergence of an empty space. and the formation of what scientists call the protoplanetary disk. And it is the gravitational action of our Astro-King that led to the collision and condensation of the material present on this disc and, over time, to the origin of the planets [19659005] Made unpublished
For the first time in history, team of scientists managed to record an image that shows this training process – which is the one you can see below – and the novelty is a bit a feat. According to Maria Temming of Science News, the disc was published by a team of astronomers at the Max Planck Institute in Germany, and is an exoplanet orbiting its star, named PDS 70, an orange dwarf that is 370 light-years from Earth. See the photo:
Look at it! In fact, astronomers had already detected several protoplanetary disks before, and even captured the evidence of the presence of planets in these places, but they had never been able to record the image of any one. 39 between them. In the case of PDS 70, it took scientists time to keep an eye on this star, precisely because they suspected that there might be a "birth" of the planet.
However, it is not easy to record that moment that, beyond the immense distance, the light emitted by the star can disturb enough observation . The researchers conducted the studies using SPHERE, an instrument of the very large Chilean telescope (VLT), used to hunt exoplanets, and to "see" the newborn, scientists blocked some of the light emitted by the latter . through a device called a coronagraph.
After collecting the necessary data and filtering the light emitted by the PDS 70, astronomers were able to identify the planet which, by the way, is about 3 billion kilometers from its
The world was baptized PDS 70b, and badyzes up to now have shown that it is a gaseous mbad giant between 2 and 17 times that of Jupiter, the largest planet in the solar system . In addition, it is possible that it has cloud cover and the temperature of its surface varies between 730 and over 1300 degrees Celsius. Another thing that astronomers have established is that their star is quite young, about 5.4 million years old, and that the planet has not yet completed its training. Fascinating, you do not agree?
