Astronomers observe newborn planets evolving from gas and dust particles

ABC  

Astronomers have observed up to three newborn planets evolving from a disk of gas and dust particles circling a distant Sun-like star. "We have found a clear case where we can join all of the dots showing how planets are forming by accreting the gas and dust left over from the formation of their star," said one of the study's authors, Professor Peter Tuthill of the University of Sydney. The astronomers identified light emissions caused by very hot gas falling onto the newly forming planet which they named LkCa 15 b. A second planet named LkCa 15 c was also detected in the cleared out area, and there are indications of a possible third planet, which would be named LkCa 15 d. "This provides us with a nice story; we see the star surrounded by a disk of material, we see a gap in the disk where the material's missing, we see the planets that are in the gap, and we see material falling onto the planets."

NASA’s Webb telescope seemingly confirms controversial theory on planet formation

Salon  

Back when the stars in our universe were initially being formed, they created rotating disks of dust and gas known as protoplanetary disks. Yet recent images captured by NASA’s James Webb Space Telescope seem to contradict that notion by showing protoplanetary disks in a dwarf galaxy adjacent to our own Milky Way, the Small Magellanic Cloud. Focusing on a cluster …

Hubble Detects How Planet Forms Through 'Intense And Violent' Process, Orbiting A Young Star

ABP News  

New Delhi: NASA's Hubble Space Telescope has detected a planet forming through what scientists describe as an "intense and violent process." It has long been debated that planets like Jupiter form through a process called "disk instability", which refers to a model for giant planet formation in which a region of a circumstellar disc becomes dense and cool enough to …

In a unique study, astronomers have found compelling evidence that the planets begin forming while stars are still infants and they grow up together like siblings. This new result, published in the journal Nature, shows the youngest and most detailed example of dust rings acting as cosmic cradles, where the seeds of planets form and take hold. Proto-stars as young …

Surviving samples of pre-solar dust are most likely to be preserved in comets – small, cold bodies that formed in the outer solar nebula. Scientists have discovered that interplanetary dust particles in comets contain leftovers from the early solar system, which may provide a deeper understanding of how the planets were formed. The types of carbon that rims the subgrains …
