Volcanism in the early solar system

A new study has found that volcanism was already happening on small asteroids in the first few million years after the solar system’s birth. The new findings are based on one of the most unique meteorites ever found.

Astronomers discover a bizarre type of hybrid star
Scientists have found the weirdest star they’ve ever seen, a dying red supergiant star with a neutron star in its core. Discovery of this strange star means there’s a totally new way to produce heavy elements in the universe.

Tiny dust grains may be from interstellar space

Scientists believe they have obtained the first samples of space dust from beyond our solar system. The tiny grains have very diverse chemical compositions and structures compared to grains from inside the solar system.

High-speed solar winds increase lightning strikes on Earth

A new study has found that lightning on Earth can be triggered by the Sun’s solar winds. Scientists found a significant increase in lightning strikes for up to 40 days after the arrival of high-speed solar winds.

Powerful new privately owned Earth observation satellite launched
An Atlas V rocket has blasted into orbit carrying the most powerful Earth imaging satellite ever built for a non government organisation. DigitalGlobe’s WorldView-3 satellite will image the planet from a 617 kilometre high orbit with a resolution down to under a metre.
