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.
Launched by NASA in 1977, the Voyager 1 spacecraft has been operating for 34 years, 9 months and 17 days.
Complex organic compounds probably formed easily in the early solar system, say scientists at the University of Chicago and NASA Ames Research Center.
Since last July, NASA’s Dawn spacecraft has been orbiting the asteroid Vesta and transmitting gigabytes of images and other relevant data.
Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft seem to indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System.
The solar system could once have had a fifth giant planet, which got hurled out into space billions of years ago.
