Experts believe the hollow metal balls could either be the debris from a Chinese rocket, or fuel tanks from other space launch vehicles.

The historic image is a crucial step toward a new understanding of black holes, gravity and spacetime.

It could be nothing but a rock formation, but speculation abounds.

Scientists are exploring converting compounds from the moon to facilitate an "extraterrestrial photosynthesis" strategy.

An international centralised space governance system is needed as “humanity approaches a time when humans may realistically be living and working in space.”

"Although the universe is expanding at an accelerating rate today... a dynamical form of dark energy (known as quintessence) could cause the acceleration to come to end."

The constant humming noise, pressurized cabin, and dry air suppress our sense of smell and also diminish our ability to taste sweet and salty things.

“It opens a new frontier where you're using the Earth as a fishing net for these objects.”

The collision, which is a historical first, may have formed a large crater on the moon’s surface and raises concerns about space junk.

"[O]ur new understanding has greatly expanded the definition of a potentially habitable world in our Solar System and beyond."

“The exoplanet seems to be spiraling away from its star, an unexpected finding given the power of [its sun’s] gravitational pull.”

“If this is proven to be the case in other gas clouds, it will be revolutionary for the star formation community.”

"While much is being done to clean up our oceans and our rivers, space debris is the responsibility of all nations who operate there." 

The Parker probe flying into the solar corona represents “one of the last great unknowns."

With space exploration expected to rise soon, this method is aimed at making the process environmentally sustainable and cheaper.

The research could help decode mysteries about the Earth and also offer answers about origin of water in other planets, scientists say.

“Up to one in five of the earliest galaxies may have been missing from our map of the heavens,” researchers noted.

The growing space debris problem may result in the “Kessler Effect” - when smaller bits of junk may collide to make the orbit unusable.
