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.

A new study published on April 26, 2018, suggests that TRAPPIST-1e, an exoplanet orbiting the red dwarf star TRAPPIST-1, has a large iron core. This could mean that the planet TRAPPIST-1e may have a protective magnetosphereNotes 1 like we have here on Earth.

You can help NASA on some projects: for instance, citizen scientists helped NASA identify an aurora-related celestial phenomenon, now called STEVE. Want to become a citizen scientist? You can find projects on NASA website.

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.

On March 24, 2017, astronomers led by Carnegie’s Meredith MacGregor and Alycia Weinberger discovered that a giant stellar flare erupted from Proxima Centauri, the closest star to the Sun (Proxima Centauri means ‘nearest [star] of Centaurus’), using data from the Atacama Large Millimeter/submillimeter Array (ALMA). The huge flare was 10 times larger than a major solar flare. And it blasted Proxima Centauri b (also called Proxima b), the exoplanet orbiting within the habitable zone of Proxima Centauri, with 4,000 times more radiation than Earth gets from solar flares. The event probably wiped out the exoplanet’s atmosphere (if exists any), and dimmed the last hopes of extraterrestrial life on it. This finding is published in The Astrophysical Journal Letters on February 22, 2018.

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” .

Are we alone in the Universe? Or any other life forms exist out there? A new study, published on the Proceedings of the National Academy of Sciences of the United States of America (PNAS)Notes 1 suggests that the life emerged so early on Earth – it should be widespread. In other words, the Universe should be filled with life.

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.

On June 19, 2017, NASA’s Kepler space telescope team has released a mission catalog of planet candidates. The final catalog introduces 219 new exoplanet candidates, and 10 of them are near-Earth-size and orbiting their stars in the circumstellar habitable zone.Notes 1

Scientists spotted water in the atmosphere of 51 Pegasi b, one of the first exoplanets ever been discovered. It is around 50 light years away – so we can call it a “nearby” exoplanet – and it is in the constellation of Pegasus.
