Earth can be a model for detecting vegetation on exoplanets

Back in December 1990, during its flyby of Earth, NASA’s Galileo spacecraft, which studied the planet Jupiter and its moons, as well as several other Solar System bodies, pointed its instruments towards Earth, at the urging of Carl Sagan. And, it has found evidence of life on our planet. This can be a key to detect […]

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. […]

TRAPPIST-1e has an Iron Core

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 magnetosphere Notes 1 as we have here on Earth.

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 […]

Huge Proxima Centauri flare blasts nearest exoplanet Proxima b

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 […]

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 […]

The oldest fossils suggest that life should be common in the Universe

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 […]

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 […]
