The mission could launch as soon as the 2030s, the researchers said.

If we’re migrating slowly away, is our speed changing, too? Every year, planet Earth completes one revolution around the Sun while spinning on its axis. On a year-to-year basis, our […]
Galaxies can have regions both hotter and colder than the background radiation of the Universe. When we talk about the depths of space, we get this picture in our heads […]
New research shows that neurons in autistic brains begin to developmentally diverge in early prenatal stages.
On the morning of March 31, 2020, these three worlds will be at their mutual closest in 20 years. For the past few weeks, Mars, Saturn, and Jupiter have all shone […]
The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
There are three factors all competing to determine the fate of the Earth, and the one that’s winning now won’t win in the end. If you could measure the average distance […]
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
The dream of an ‘Earth-like’ planet showcases our astrobiological ignorance. Over the past decade, our understanding of what planets exist around stars other than our own has exploded. The number […]
The Moon, Venus, and Jupiter are the brightest night sky objects. On Thursday evening, November 28, they’ll all align, plus Saturn, too. As the planets orbit the Sun throughout the year, […]
It’s one of Einstein’s most bizarre predictions. And it’s true. There’s no such thing as absolute time. No matter where you are, how fast you’re moving, or how strong the gravitational […]
Even the ones hunting for aliens aren’t excited. Here’s the reason why. In this world, there are very few issues more polarizing than the notion of aliens. For as long as […]
Is it groupthink? Or is there a deeper reason? In the early half of the 20th century, even after the discovery of the expanding Universe, physicists considered a wide variety of […]
In 2006, the IAU demoted Pluto. Here’s what we know today. In 2006, the last planet in our Solar System suffered an unforgettable insult, as Pluto — known for generations as our ninth […]
Even though it was the crowning achievement of Einstein’s career, he was only a small part of the full story. If you were a physicist in the early 20th century, there […]
Leap years will only get us through the next few thousand years before we have to fix it. With every year that passes, we assume that two separate things will both […]
A tiny layer of microscopic dust is the only reason it appears red. When we look out at our planet Earth from space, we see a myriad of diverse colors. The […]
Science can teach us so much about our planet, but something more must compel us to take care of it. If you want to understand our planet, the best way to […]
The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]
“On the spectrum from worry to action, parents can choose to act,” a new report states.
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
Catch Saturn at its biggest and brightest, and view its rings while you still can. Right now, in Earth’s skies, Saturn appears at its biggest and brightest. A view of tonight’s […]
A U.S. government intelligence agency develops cutting-edge tech to predict future events.
The view from beyond Pluto is far enough from Earth that we can see the stars shift. NASA’s New Horizons, humanity’s first spacecraft to encounter Pluto, is more than 4.3 billion […]
There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]
Debris from Pluto-sized collisions, not aliens, are streaming through the galaxy. In 2017, scientists discovered an object passing through our Solar System that was unlike anything else we had ever seen. […]
Avi Loeb says it’s aliens. Every other astronomer disagrees. Here’s why. In 2017, an astronomical event occurred that was unlike any other: for the first time, we observed an object that […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
It might have been Einstein’s greatest blunder, but it’s our leading theory today. One of the most mysterious components in the entire Universe is dark energy, which — if we’re being honest with […]
Hawking radiation should really be happening, but black holes are farther from decaying than ever before. Black holes are, in many ways, the most extreme objects that will ever exist in […]
