Humans are able to see from birth, so we often take it for granted. Trying to teach a machine to see from scratch, however, is a whole other ballpark. But first, what even is “seeing” in the first place?

 

Vision has three parts:

  1. Being able to physically “see” the object in front of you
  2. Understanding and recognizing what it is
  3. Being able to respond to it

 

In humans, this process corresponds to our eyes being able to see what is in front of us, then our brains recognizing what it is.

The Neptune-like planet discovered is thought to be more than four times the size of the Earth-sized white dwarf. University of Warwick discovered the ring of gas using the Very Large Telescope in Chile.

 

Evidence of a giant planet orbiting a dead white dwarf star has been found for the first time. Until now there was no example of a planet that had survived a star’s transition to a white dwarf – leaving little hope for our own planet’s future.  

 

Astronomers say the evidence for the distant planet comes in the form of a disc of gas created from its evaporating atmosphere.

The Neptune-like planet discovered is thought to be more than four times the size of the Earth-sized white dwarf. 

 

The giant planet orbits the star about once every 10 days, leaving a trail of gas comprised of hydrogen, oxygen and sulphur in its wake.

ADEPT, an artificial intelligence model developed by MIT researchers, demonstrates an understanding of some basic “intuitive physics” by registering a surprise signal when objects in a scene violate assumed reality, similarly to how human infants and adults would register surprise.

 

We often think of artificial intelligence as a tool for automating certain tasks. But it turns out that the technology could also help give us a better understanding of ourselves. At least that’s what a team of researchers at the Massachusetts Institute of Technology (MIT) think they’ll be able to do with their new AI model.

According to the latest theories, planets are formed from fluffy dust aggregates in a protoplanetary disk around a young star. But young stars are not the only objects that possess dust disks. In a novel approach, the researchers focused on heavy disks around supermassive black holes in the nuclei of galaxies.

 

"Our calculations show that tens of thousands of planets with 10 times the mass of the Earth could be formed around 10 light-years from a black hole," says Eiichiro Kokubo, a professor at the National Astronomical Observatory of Japan who studies planet formation. "Around black holes, there might exist planetary systems of astonishing scale."
