Observe the world of aliens

Princeton University's team of scientists and engineers has developed ground-based equipment and is considered a great step forward in the study of galactic exoplanets by the ability to separate reflected light from distant planets. This sticky rice.

The device is named CHARIS (Coronagraphic High Angular Resolution Imaging Spectrograph) - developed by the team of Professor N. Jeremy Kasdin, expert in the field of mechanical and aerospace of Princeton University.

The image is recorded by CHARIS from the galaxy HR8799 with points marked as planets orbiting their star.

With 9 elements, 5 filters, two prism devices and micro lens system, CHARIS has a weight of 226.8kg and needs maintenance at -223.15 ^o C.

CHARIS has the ability to separate light reflected from planets in other galaxies, something that has not been done before because these planets are often much fainter than the central star galaxy they orbit around. .

"By analyzing the spectrum of these planets we can really discover more about them. You can collect enough data to calculate the density, temperature, and life span of the planet." - researcher Tyler Groff explained.

Spectral images provided by CHARIS are capable of assisting in calculating the characteristics of a planet such as mass, temperature, atmosphere.

" Alien planets" are discovered planets outside the solar system, they also orbit another star.

Scientists have achieved a lot of " extraterrestrial " research achievements thanks to the Kepler space telescope. But except for their location, scientists still don't know much about the detailed characteristics of these extrasolar planets.

CHARIS was built to solve this problem. More than three decades since the first extraterrestrial discovery in 1990 and now, with the development of support equipment as well as the goal of seeking new settlements for human beings, exoplanets new focus to discover more.

"With the appearance of CHARIS, we can do more than just define the position of" extraterrestrial ", the calculation of temperature and atmospheric composition becomes much easier" - Olivier Guvon, Head of the Subaru Telescope telescope program development team in Hawaii, the research collaboration unit built CHARIS added.

Extraterrestrial planet is the most interested object in space research.

"Alien planet" is being focused on research in the near future and with the presence of CHARIS, the Subaru Telescope plus the appearance of James Webb Space Telescope, is expected to be introduced in 2018, will be very useful and powerful tools.

"We are really excited about this success," said Tyler Groff, a member of the research team currently working in Nasa, "Charis will begin its official operation in February."
