Previous studies have suggested that Venus may have been a much more hospitable place in the past, with its own liquid water oceans. A team of astrophysicists investigated whether our planet's twin did indeed have milder periods.

At the heart of planets, extreme states are to be found: temperatures of thousands of degrees, pressures a million times greater than atmospheric pressure. They can therefore only be explored directly to a limited extent - which is why the expert community is trying to use sophisticated experiments to recreate equivalent extreme conditions.

Considered an ultra-hot Jupiter - a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain - the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists had realized.

When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn't always believing. A new study finds that next-generation telescopes used to see exoplanets could confuse Earth-like planets with other types of planets in the same solar system.

When the universe was about 3 billion years old, just 20% of its current age, it experienced the most prolific period of star birth in its history. But when astronomers gazed toward cosmic objects in this period, they found something odd: six early, massive, 'dead' galaxies that had run out of the cold hydrogen gas needed to make stars.

The idea that 'space is getting crowded' has been around for a few years now, but just how crowded is it? And how crowded is it going to get?

Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin. Gamma rays are one of the most energetic forms of light in the universe, and Aussie researchers say they have been able to pinpoint how they form.
