New work from Carnegie's Scott Sheppard and Chadwick Trujillo of the Gemini Observatory reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the Solar System.
Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe.
More than 400 years after its discovery by astronomer Galileo Galilei, the largest moon in the solar system – Jupiter's moon Ganymede – has finally claimed a spot on the map.
Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed.
At 10:00 GMT on Monday, the most important alarm clock in the Solar System will wake up ESA’s sleeping Rosetta spacecraft.
Cosmochemists have solved a long standing mystery in the formation of the solar system: Oxygen, the most abundant element in Earth's crust, follows a strange, anomalous pattern in the oldest, most pristine rocks, one that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth.
It has long been assumed that our solar system, like a comet, has a tail. Just as any object moving through another medium – for example, a meteor traveling through Earth’s atmosphere – causes the particles to form a stream trailing off behind it.
A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet (KELT-6b) in another solar system 700 light-years away.
In February, a speeding asteroid slammed into our atmosphere and exploded high over Russia’s Ural region, injuring hundreds and causing millions of euros of damage. What should we do if we have a similar – or even bigger – strike in the future?
Researchers say they've conducted the first reconnaissance of a distant planetary system, collecting the spectra of four red exoplanets which orbit a star 128 light years away from Earth.
NASA's Interstellar Boundary Explorer (IBEX) spacecraft has helped explain the striking narrow ribbon of charged particles emanating from the boundary of the solar system.
University of Leicester planetary scientists believe they've found the first clear evidence that auroras occur outside our solar system.
Astronomers have shed further light on the mysterious process of how young stars and their planetary systems form.
NASA's Voyager 1 spacecraft has entered the last region it has to cross before reaching interstellar space.
NASA’s Messenger spacecraft has found that water ice likely exists on the frozen poles of Mercury, the planet closest to the sun.
Unlike its bigger sister Pluto, dwarf planet Makemake doesn't have an atmosphere, new observations have revealed.
European Space Agency astronomers have found evidence for a dying sun-like star coming back to life - something they say may happen to our own sun in a few billion years.
Our solar system didn't, as previously thought, take twice as long as most to form, new research shows.
Thirty-five years ago today, NASA's Voyager 1 spacecraft set off on its journey to interstellar space - and it's now teetering on the edge.
Astronomers have discovered the first exoplanetary system to look like our own solar system, with regularly-aligned planets.
