Going back to the moon will give us fresh insights about the creation of our solar system.
- July 2019 marks the 50th anniversary of the moon landing — Apollo 11.
- Today, we have a strong scientific case for returning to the moon: the original rock samples that we took from the moon revolutionized our view of how Earth and the solar system formed. We could now glean even more insights with fresh, nonchemically-altered samples.
- NASA plans to send humans to a crater in the South Pole of the moon because it's safer there, and would allow for better communications with people back on Earth.
She may not be ours forever.
- A new study suggests that the moons of gas-giant exoplanets may break away into their own orbits, called "ploonets."
- Planet + moon = ploonet.
- As the gas giants move inward toward their suns, the orbits of their moons are often disrupted, according to new computer models.
Conspiracy theories about the event dating back to the 1970s are in fact more popular than ever.
The more Greenland melts, the more Greenland melts. Here's why.
- The Arctic right is currently warming about twice as fast as the rest of the world.
- Ice is white and bright and is able to reflect solar energy back into space. When it melts and exposes dark, open ocean, that open ocean absorbs more sunlight and more energy. This creates a kind of feedback loop.
- The darkness absorbs more solar energy — more sunlight. In turn, this accelerates the melt of the ice.
While the world considers future trips to Mars, two astrophysicists make a case for exploring asteroids.
On the same day that the Earth survived an expected near-miss with asteroid 367943 Duende, Russian dashcams unexpectedly captured footage of a different asteroid as it slammed into the atmosphere, exploded, and injured more than 1,000 people.
