Pluto Has Ice Volcanoes & The Reason For T. rex's Stubby Arms & The Birth Of A Gas Giant

 

Pluto Has Ice Volcanoes

Pluto, the most beloved dwarf planet, was visited by NASA's New Horizon's mission in 2015. Scientists have sifted through the data over the past few years to discover what makes Pluto tick, using the most precise images of the icy world's surface ever taken. 

Researchers discovered a series of dome-like structures southwest of Sputnik that may have been caused by volcanic activity spewing material onto Pluto's surface. The only drawback is how cold those volcanoes are. 

Volcanoes are well-known for spewing liquid rock and gas into the air and onto land from beneath the surface. A completely different kind of tectonic activity can be found on Pluto, which is located closer to the edge of the solar system. Ices on Pluto would have to be melted and pushed to the surface by heat from the dwarf planet's interior in order for ice volcanoes to exist, indicating that Pluto once had a geological life. 

Exploring Pluto, once thought to be a cold, dead rock, adds an exciting new dimension if any geological activity is discovered there. Additionally, an examination of the area's impact craters suggests that the activity is relatively recent. 

As we gain more knowledge about Pluto, it becomes increasingly apparent that it is an alien world located in our own stellar backyard

The Reason For T. rex's Stubby Arms

The T. rex is probably the best-known dinosaur ever. Even though it probably was horrible, its stubby little arms seemed to go against its massive body, which was perfectly suited for tearing into the bodies of prey animals. 

The reason and purpose of T. rex's arms have been debated by scientists for decades without a satisfactory conclusion. Their arms may have been used as pectoral clappers during mating or to raise themselves off the ground in the event of a fall, according to previous hypotheses. The problem is that larger limbs would have been more useful for each of those activities. There was no functional explanation for why their grabbers were so insignificant. 

However, a recent study suggests that we may have misinterpreted T. rex's arms. The new hypothesis is based on the idea that the point was to get smaller. 

Similar to some modern reptiles, there is evidence that T. rex groups engaged in communal feeding, and their arms may have been the target of another Rex's jaws, either intentionally or unintentionally. The possibility of being bitten by a peer outweighed any advantages their arms provided over time. The T. rex's arms shrivelled because it was better for its evolution to keep them out of the way

The Birth Of A Gas Giant

The planets in our solar system were well-formed and mature by the time humans were made by evolution and telescopes were made by humans. We could only see the planets Jupiter and Saturn in their current form when we first looked into the cosmos and discovered that there were other worlds. Since light travels at the speed of light, we could only see them about an hour ago. To understand how gas giants and other planets formed, we had to draw inferences and look at systems farther away in both time and distance. A system called AB Auriga, located 505 light years from Earth, was the focus of a recent study that was published in the journal Nature Astronomy. 

The young star at the center of that system is in its planetary nursery phase and is estimated to be only 2 million years old (again, considering that we are inevitably looking back half a billion years). A gas giant roughly nine times the size of Jupiter is currently forming among the planets in formation. 

Astronomers are getting a rare look at the formation of gas giants thanks to the discovery of this planet
