Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the Sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from extreme

As black holes spin, they drag space-time along with them, and scientists have proposed that this could be a source of energy for an advanced civilization, harvesting momentum from material ejected from this twisting spacetime. The concept has been generalized, and it's theoretically possible to extract energy from anything spinning. Now, researchers have mimicked the process in the lab, beaming electromagnetic waves at a spinning object and extracting energy.

A gravitational lens is the ultimate funhouse mirror of the Universe. It distorts the view of objects behind them but also supplies amazing information about distant galaxies and quasars. Astronomers using Hubble Space Telescope (HST) recently released a new image of one of

Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06

Black holes often appear in science fiction movies, largely because elements of their existence are still a mystery. They have fascinating impacts on the surrounding region of space too with distortions in space and time high on the list. A team of astronomers have found a

Astronomers have several classifications for stars: the Sun is a G-type star. As you go up the list, the next hotter stars are the F-type, with surface temperatures in the range of 6200–7200 K. Could these stars have habitable zones where planets might support life? According to a new study, there have already been planets discovered within the habitable zones of F-type stars, which also lie outside the region where there is too much ultraviolet radiation.

NASA's Juno spacecraft was sent to Jupiter to study the gas giant. But its mission was extended, giving it an opportunity to study the unique moon Io. Io is the most volcanically active body in the Solar System, with over 400 active volcanoes.

Global internet access does seem like a worthy enterprise yet the rise of satellite megaconstellations there is a danger of the night sky becoming ruined. Astronomers the world over are keeping an eye on the impact these satellites are having on the night sky. Until recently

When you look at the Moon, you don't see any water on its surface. That doesn't mean there isn't any. In fact, there's a lot of "wetness" on the Moon, but it's in places and forms we can't see. Understanding where all those resources are

As someone that has always lived in the UK countryside I am no stranger to the glory of a dark star-filled sky. Sadly 60% of the world's population has already lost access to the night sky thanks to light pollution. Across Europe and the US that number climbs to nearer
