Exciting news! NASA’s planet-hunter TESS Space Telescope (Transiting Exoplanet Survey Satellite) has discovered its first Earth-sized exoplanet in its star’s habitable zone. The discovery was announced by NASA on January 7, 2020. The planet is named “TOI 700 d”. Using NASA’s Spitzer Space Telescope, astronomers confirmed the discovery and have modeled the planet’s potential environments […]
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 (see notes 1) as 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 the NASA website.
Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand grand … (insert a hundred or a thousand “grand” 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, […]
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 […]
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 […]
On February 22, 2017, NASA has announced that seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around TRAPPIST-1, a tiny, nearby, an ultra-cool dwarf star located 39 light-years (12 parsecs; 370 petametres) away from Earth in the constellation Aquarius. The good news is: three of these planets are firmly in the habitable […]
Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. But if you don’t know where to look, you won’t notice it. If it was much brighter, its appearance in the sky would be sensational. The moon is a good reference for what we’d see if our galaxy’s […]
