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.

What would happen if the Earth started spinning backward?
The dynamics of the ocean and the atmosphere are strongly influenced by the Earth’s rotation. Currently, our planet rotates from west to east (prograde, which appears counterclockwise) with a linear velocity of 465.1013 m/s (1674.365 km/h or 1040.40 mph) at the equator. What would happen if the Earth started spinning backward (from east to west)?
Virtual Moon Tour [4K Ultra HD]
Using data provided by the Lunar Reconnaissance Orbiter spacecraft (see notes 1) since 2009, NASA has published an amazing virtual Moon tour in 4K Ultra HD (see notes 2). As the visualization moves around the near side, far side (see notes 3), north and south poles, interesting features, sites, and information gathered on the lunar …
Want to Become a Citizen Scientist for NASA? Now you can
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.
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 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, …

Rotating Moon from the Lunar Reconnaissance Orbiter
NASA APOD (Astronomy Picture of the Day) published an amazing video showing a rotating Moon. In fact, no one sees the Moon rotate like this. We see only one side of the Moon because the Moon is tidally locked to Earth. But, thanks to modern digital technology combined with many detailed images returned by the Lunar …

The “Synestia Theory” says the Moon was formed 1,000 years earlier than Earth
According to a new study, the Moon might have been formed a thousand years earlier than Earth. The new “synestia theory” suggests a Mars-sized object smashed into the proto-Earth. The “giant impact” vaporized about 10 percent of the rock and liquefied the rest, and created a rapidly spinning donut-shaped mass of vaporized rock called “synestia”. …

We May Have Already Detected Signs of Alien Microbes on Saturn’s Moon Enceladus
According to a new study, microbes like those found in Earth’s deep ocean could potentially thrive in the underground ocean of Saturn’s icy moon Enceladus. Both molecular hydrogen (H2) and methane (CH4) already have been detected in the plume. Researchers have shown that Methanothermococcus okinawensis, a methanogenic archaeon first isolated from a deep-sea hydrothermal vent …

Amateur Astronomer Recorded a Newborn Supernova Accidentally
On September 20, 2016, Argentinian amateur astronomer Victor Buso was testing his camera-telescope setup. He pointed his Newtonian telescope at NGC613, a barred spiral galaxy located some 67 million light-years away in the southern constellation of Sculptor. Then he started taking a series of short-exposure photographs. To ensure his new camera was functioning properly, he …

Asteroid Mining: We Need Powerful Rockets like Falcon Heavy
On February 6, 2018, SpaceX successfully tested Falcon Heavy, the most powerful rocket that the American company ever built. When lifted off, it became also the most powerful operational rocket in the world. Powerful rockets like Falcon Heavy may one day carry humans to the Moon or Mars. But there might be an even more important use of powerful …
