Dr Tommi Markkanen, an expert on the False Vacuum has kindly answered these questions in an email interview: 1. Does a false vacuum decay due to quantum tunneling have a realistic chance happening…

(Inside Science) -- For the first time, an intact world may have been discovered around a white dwarf, suggesting that even after typical stars die, they may still host planets, a new study finds.…

The Andromeda galaxy, our nearest large galactic neighbor, has been found to have a nearly invisible halo of diffuse plasma that extends about halfway to our Milky Way. That's 1.3 million light-years…

The false vacuum collapse is about a remote possibility, not just billions of years in the future, so far in the future that all the stars in the night sky have run out of fuel, long before. There…

A lava tube is just what it sounds like; a cave created when the surface of lava hardens but continues to flow underneath. When that trickles to a halt, the cave is left behind. These remaining caves…

The origin of carbon in the Milky Way is a mystery but one source of many elements is not: Dying white dwarfs. As those dying stars pass into oblivion, they sprinkle their ashes into the cosmos.…

When it comes to evolutionary biology and life on other planets, there is talk of amino acids, the building blocks of our existence. But for any of that to work we first needed magnetic fields and…

How a sunset would appear on other planets is a staple of science-fiction. The sun is as fundamental to grounding our existence as the earth, for most of us. Yet lots of people go months without…

Though we've only detected a few thousand exoplanets, there are likely 6,000,000,000 Earth-like ones out there, and that means millions could be "ocean worlds" capable of supporting life. Right now,…

Pluto, along with many other dwarf planets in the outer solar system, is often thought of as dark, icy and barren – with a surface temperature of just −230°C. But now a new study, published in…
