Pale blue dot – or not?

Appearances can be deceiving. This thick, cloud-rich atmosphere rains sulphuric acid and below lie not oceans but a baked and barren lava-strewn surface. Welcome to Venus.

How Venus and Mars can teach us about Earth

One has a thick poisonous atmosphere, one has hardly any atmosphere at all, and one is just right for life to flourish – but it wasn't always that way. The atmospheres of our two neighbours Venus and Mars can teach us a ...

Small, hardy planets most likely to survive death of their stars

Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research from the University of Warwick has found. The new research is published ...

Gravitational forces in protoplanetary disks may push super-Earths close to their stars

The galaxy is littered with planetary systems vastly different from ours. In the solar system, the planet closest to the Sun—Mercury, with an orbit of 88 days—is also the smallest. But NASA's Kepler spacecraft has discovered ...

Occurrence of back-to-back heat waves likely to accelerate with climate change

As the planet continues to warm, multi-day heat waves are projected to increase in frequency, length and intensity. The additive effects of these extreme heat events overwhelm emergency service providers and hospital staff ...

A closer look at Mercury's spin and gravity reveals the planet's inner solid core

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it—very, very carefully. This is exactly what NASA planetary ...

Exploring Mercury in a new book

Up until 2008, only one spacecraft had ever visited the planet Mercury, and it didn't linger long. NASA's Mariner 10 mission flew past the tiny world three times in the 1970s, giving humanity a helpful but limited glimpse ...

Scientists track deep history of planets' motions, and effects on Earth's climate

Scientists have long posited that periodic swings in Earth's climate are driven by cyclic changes in the distribution of sunlight reaching our surface. This is due to cyclic changes in how our planet spins on its axis, the ...

Heavy metal planet fragment survives destruction from dead star

A fragment of a planet that has survived the death of its star has been discovered by University of Warwick astronomers in a disc of debris formed from destroyed planets, which the star ultimately consumes.

What scientists found after sifting through dust in the solar system

Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it's often in rings. Several dust rings circle the Sun. The rings trace the orbits ...
