Beyond the outer edge of the Solar System, mysterious, unknown worlds await by the thousands. Astronomers can now finally find them and explore them - but will we find another Earth?
Although it has yet to fly any paying passengers and is currently loss making, Virgin Galactic aims to be profitable by 2021.
Following announcements by France and the US, NATO is expected to start using space weapons.
Stars begin their life inside very large, fluffy clouds of space dust and gas called nebulae.
Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
The opportunities in space are limitless. But without a sustainable approach to the space industry, our ability to exploit them won't be.
A giant exomoon hundreds of times the size of Earth is revealing secrets about how giant planets like Jupiter and Saturn formed. They might also help astronomers find planets where life may thrive.
The first Martian might just be a human being.
The Universe is mind-bogglingly large and with the latest technology, the search is only just starting to heat up.
Kepler-452b is sometimes called 'Earth 2.0', but there's a lot we still don't know about it.
The International Space Station is the biggest human made structure in space and the third brightest object in the sky. But the living conditions for the six astronauts on it are quite cramped.
The constant pressure of gravity affects our thoughts and perception, but it's so constant we haven't noticed – until now.
Most people think that many millions of years ago, Saturn didn't have rings at all. Instead, it had a big moon moving around it. Eventually, the moon burst and broke into pieces.
It's established Mars was once a planet with surface-level water. So with multiple MARS missions starting next year, the key to seeking out martian life may instead lie in the contents of its 'dust'.
NASA is reportedly investigating the first alleged crime in space. But criminal jurisdiction aboard the International Space Station is much more straightforward than it would be for space tourists.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
Although the rings of Saturn may look like a permanent fixture of the planet, they are ever-changing. New analyses of the rings reveal how and when they were made, from what and whether they'll last.
In an age when women were rarely allowed in observatories, Margaret Burbidge changed how we saw the stars.
An Israeli spacecraft carrying tardigrades crashed into the moon. Whether they will survive is irrelevant.
Realising the silence of outer space was what made us appreciate our precarious position down on this pale blue dot – so beginning our obsession with extinction.
