Astronomers once thought asteroids were boring, wayward space rocks that simply orbit around the Sun. But recent observations show that asteroids are anything...
A team of planetary scientists at the Australian National University found that our planet is made of the same elements as the Sun but has less of the...
A team of astronomers from the U.S. Naval Research Laboratory in Washington, DC, and the University of Colorado, Boulder, has found evidence for a fine...
‘Oumuamua, a recently discovered object of extrasolar origin, is a comet that rocks, according to a new study by astronomers at Yale University and Caltech.

Astronomers using ESA’s Gaia satellite have discovered a large stellar stream that is currently traversing the immediate solar neighborhood at a distance...
As strong impulses strike the Earth’s magnetopause, the abrupt boundary between the planet’s magnetosphere and the surrounding plasma, ripples travel...
NASA’s Parker Solar Probe successfully completed its first orbit of the Sun on January 19.

Astronomers using ESA’s galaxy-mapping spacecraft Gaia have discovered the first direct evidence that white dwarfs form crystal cores of metallic oxygen...
The Large Magellanic Cloud, a dwarf galaxy located approximately 163,000 light-years away, is on a collision course with the Milky Way with which it will...
The ‘bow shock’ is the first boundary the solar wind encounters as it approaches planets or comets. From 2014 to 2016, ESA’s Rosetta orbiter studied...
Forty-one years after it launched into space, NASA’s Voyager 2 spacecraft has crossed the outer edge of the heliosphere. Called the heliopause, this...
NASA’s Magnetospheric Multiscale (MMS) mission consists of four identical spacecraft that orbit around Earth through the dynamic magnetic system surrounding...
A team of researchers from Anglia Ruskin University and the University of Exeter, UK, has created the soundtrack of the Martian sunrise captured by NASA’s...
The total solar eclipse of 21 August 2017 traversed 5,000 km from coast to coast of North America. In its 90-min span, sunlight dropped by three orders...
NASA’s Voyager 2 spacecraft has detected an increase in cosmic rays that originate outside the Solar System. Currently, the probe is approximately 11...
An international team of researchers led by RMIT University has developed paper-based UV sensors that could help people manage vitamin absorption and avoid...
Our Sun rotates faster at its equator than at its poles. This process is known as differential rotation and is seen in the motion of sunspots. Now, a team...
