Wherever we humans go, we leave behind a mess. That goes for space, too.

Like many other spiral galaxies in the Universe, the Milky Way Galaxy consists of two disk-like structures – the thin disk and the thick disk. The thick disk, which envelopes the thin disk, contains about 20 percent of the Milky Way's stars and i

Scientists said Wednesday they have come up with an environmentally-friendly method that uses artificial sunlight to transform plastic into power-generating chemicals, as countries worldwide battle to reduce waste.

We can use just about any part of the electromagnetic spectrum to make a laser - from long-wave microwaves to bursts of highly powerful X-rays. The only ones we've had trouble with have been the ultra-short wavelengths making up the gamma ray part

Tired? Join the club.

The surface of the Sun is never still. Upon this burning ball of gas, a continual flow of super-hot plasma creates ropes of magnetic fields that can twist and tangle with one another.

A unique material that appears to decouple an object's temperature from the amount of thermal radiation it produces could provide a new way of hiding from infrared cameras (not to mention bloodthirsty aliens equipped with infrared vision).

Perhaps you remember the opening scene of Harry Potter and the Sorcerer's Stone that took place on Privet Drive. A bearded man pulled a mysterious device, called a deluminator, from his dark robe and one by one the lights from the street lamps flew

Across the Milky Way there are vacant spaces where a star once brightly shone. Some left clues in a dramatic death, or faded into retirement. Others simply moved into a new neighbourhood.

In her Hugo-finalist novel Record of a Spaceborn Few, Becky Chambers envisions a future where humanity travels the galaxy in generational ships, their entire civilisation dependent on a well-oiled system of reusing and recycling resources. Every wa

The Milky Way galaxy has its own magnetic field. It's extremely weak compared to Earth's; thousands of times weaker, in fact. But astronomers want to know more about it because of what it can tell us about star formation, cosmic rays, and a host of

Have you noticed that Orion the Hunter – one of the most iconic and familiar of the wintertime constellations – is looking a little… different as of late? The culprit is its upper shoulder star Alpha Orionis, aka Betelgeuse, which is looking

As far as hypothetical space megastructures go, the stellar engine is one of our favourites – a gigantic contraption built with the purpose of transporting our Solar System somewhere else, if we ever need to move to a different cosmic neighbourho

The Mars 2020 rover, which sets off for the Red Planet next year, will not only search for traces of ancient life, but pave the way for future human missions, NASA scientists said Friday as they unveiled the vehicle.

Schoolchildren skipping class to strike, protests bringing city centres to a standstill: armed with dire warnings from scientists, people around the world dragged the climate emergency into the mainstream in 2019.
