In about a year and a half from now, the New Horizons Spacecraft will whiz past a distant Kuiper Belt object named 2014 MU69. This rocky relic of the ancient Solar System—which is located about four billion miles away—just passed in front of a distant star, resulting in one of the more extraordinary eclipses ever…
New research links the odd and unexplained six-degree tilt of our Sun to an undiscovered planet in the outer reaches of our solar system. It’s even more evidence that planet Nine is for real.
NASA’s New Horizons space probe is currently speeding towards a mysterious Kuiper Belt Object known as MU69. Recent observations of the distant object indicate a very reddish surface—possibly even redder than the splotches found on Pluto.
New Horizons is currently making its way to the outer reaches of the Kuiper Belt en route to a distant destination beyond Pluto. Along the way, the intrepid spacecraft has captured unprecedented images of a distant object called Quaoar—a dwarf planet about half the size of Pluto.
In 2015, NASA’s New Horizons mission made history when it captured the first detailed images of Pluto at the far edges of our solar system. Now, it’s set to go even further after the NASA mission received an official green light to extend its mission into 2019.
Pluto may be long gone, but NASA’s New Horizons spacecraft is by no means finished with the outer solar system. For the second time, New Horizons has observed 1994 JR1, a 90-mile wide Kuiper Belt Object (KBO) that orbits over 3 billion miles from the sun.
Researchers working with the Hubble Space Telescope have discovered a moon in orbit around Makemake, a distant minor-planet that’s about two-thirds the size of Pluto.
The astronomical community is abuzz with the possibility that a ninth planet exists in the far reaches of the solar system. A new study by European scientists imagines what this hypothetical planet might look like, revealing important insights as to how we might actually find it.
There could be a new ninth planet floating beyond the dark edges of our solar system, according to new research published in The Astronomical Journal from CalTech professors Mike Brown and Konstantin Batygin.
Whoosh! Did you see that? It may look a bit scrappy, but the tiny white projectile at the center of the animation below—officially called 1994 JR1— is a cosmic time capsule, brought to you by a piano-sized spacecraft over 3 billion miles away. You’re looking at the closest picture yet of a Kuiper Belt Object (KBO) by…
With Pluto receding into the distance, New Horizons is speeding merrily along toward its next destination. On Wednesday, the spacecraft completed its fourth and final engine burn, placing it on course for 2014 MU69, an ancient, frozen body located more than a billion miles beyond Pluto in the Kuiper Belt.
We don’t have the funding but we have the target: the New Horizons spacecraft will adjust its course to make a flyby of Kuiper Belt Object MU69 in January 2019. This will be the most distant world ever explored.
Pluto has been puzzling us with its weirdly smooth surface, but if it’s the first Kuiper Belt Object we’ve visited, how did we know how many craters to expect in the first place? Here’s everything we’ve figured out about collisions in this chaotic area of our Solar System.
On the 23rd and 24th of January, 1930, a young astronomer working in Flagstaff, Arizona, scanned a small patch of the night sky. He was taking pictures of star positions, looking for anomalies that would signal movement somewhere at the edge of the solar system. He took the pictures then set them aside, not realizing…
By using the Gemini Planet Imager, an international team of astronomers have captured an image of a protoplanetary disc that shares remarkable similarities with our own Kuiper Belt — though as it was at a much earlier time in our Solar System’s history.
Scientists are mulling over which of two icy bodies NASA's New Horizons spacecraft should visit following its Pluto encounter this summer — provided the U.S. space agency comes up with funding for an extended mission.
Pluto is about forty times the distance from the Sun as Earth. But the Solar System is over 50000 times that length across, meaning it could be hiding some huge secrets. That's now looking like a small but real possibility.
The Kuiper Belt, the vast asteroid belt of ice and rock that lies beyond Neptune, is home to three objects big enough to be considered dwarf planets: Haumea, Makemake, and our old friend Pluto. And now, we might have found three more.
Do you want your share of scientific immortality? You can devote your life to mastering your field, examining the mysteries of the universe, and then finally arriving at one great discovery...but according to Stigler's Law, you won't get the credit.
Beyond Neptune lies the Kuiper Belt, a massive asteroid belt twenty times the size of the one between Mars and Jupiter. In this frigid, unforgiving environment, organic molecules might still survive, suggesting life's building blocks are everywhere in the universe.
