Virtual Reality Tour of 6 Real Exoplanets in 4K Ultra-HD, 360°

What would it be like to stand on the surface of another planet? “We The Curious” channel has teamed up with a group of astrophysicists to create a scientifically accurate virtual reality tour of six planets discovered outside our solar system. The fruit of this collaboration is the video below, in 4K Ultra-HD and 360-degree. Narrated and produced by Ross Exton.

Exoplanet Travel Bureau by NASA – Interactive 3D Images

Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand … (insert a hundred or a thousand grands here) children can stand on an exoplanet’s surface someday. But, we don’t have to wait. NASA has opened a new web page, an “Exoplanet Travel Bureau”, and we can, at least, see the artists’ imaginations of what an exoplanet surface look like, based on available data. NASA warns, there are no actual images of the exoplanets, obviously. With interactive 3D images, it is still an exciting experience.

Hubble Observes Atmospheres of TRAPPIST-1 Exoplanets in the Habitable Zone

Good news for the search for extraterrestrial life: the TRAPPIST-1 System might be rich (very rich!) in water and all of the planets are mostly made of rock. Using data from NASA’s Spitzer and Kepler space telescopes, researchers calculated the densities of TRAPPIST-1 planets more precisely than ever, and they determined that all of the planets are mostly made of rock. Additionally, some have up to 5 percent of their mass in water, which is around 250 times more than the oceans on Earth. Researchers published their findings in a recent study in the journal Astronomy and Astrophysics titled “The nature of the TRAPPIST-1 exoplanets” .

Watch: An 8th Planet Orbiting a Distant Star was Discovered using Artificial Intelligence and Kepler data

Using data from exoplanet-hunting Kepler Space Telescope and machine learning algorithm from Google, researchers discovered an 8th planet orbiting a distant star. The newly discovered planet is circling Kepler-90, a G-type main sequence star (Sun-like star), 2,545 light years from Earth. It is named Kepler-90i.

According to the press release from NASA, Kepler-90i is “a sizzling hot, rocky planet that orbits its star once every 14.4 day. In this case, computers using Google’s machine learning algorithm, “learned” to identify planets by finding in Kepler data instances where the telescope recorded signals from planets beyond our solar system, known as exoplanets.

TRAPPIST-1 System May Contain Water

On February 22, 2017, NASA astronomers have announced that seven Earth-sized planets have been discovered around an ultra-cool dwarf star named TRAPPIST-1 which is located around 39 light-years from the Earth. And what’s more – three of them are orbiting their star in the habitable zone. Then, an international team of astronomers led by the Swiss astronomer Vincent Bourrier from the Observatoire de l’Université de Genève used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the planets of TRAPPIST-1 system. Now, on August 31, 2017, the team announced that their findings suggest that “the outer planets of the system might still harbor substantial amounts of water”, including the three planets within the habitable zone of the star – TRAPPIST-1e, f, and g. This result lends further weight to the possibility that these planets may indeed be habitable.
