Well, here's something you don't see every day. On November 18, 2020, the Solar Orbiter managed to capture three of our solar system's eight planets in a single frame, according to a European Space Agency statement. The resulting four-second movie was stitched together from a series of still images taken across...

2019 was the year when America's space exploration efforts went private. Both SpaceX and Boeing performed their first test launches of the Crew Dragon and Starliner spaceships, respectively, but whereas the former succeeded, the latter failed.

According to a new tectonic plate motion model, in the next 200 million years, Eurasia and the Americas will collide to form a new supercontinent.

Residents in Bali's Buleleng regency widely reported hearing a loud "boom" sound yesterday morning, which may have come from an extraterrestrial object, experts say Speaking about the phenomena, the National Institute of Aeronautics and...

If we want a liveable future for our grandchildren is it ethical to reduce the number of people being born into that world?

A planet's density is determined by its composition as well as its size: Gravity compresses the material a planet is made of, increasing the planet's density. Uncompressed density adjusts for the effect of gravity and can reveal how the composition of various planets compare.

A new international study led by astrophysicist Eric Agol from the University of Washington has measured the densities of the seven planets of the exoplanetary system TRAPPIST-1 with extreme precision, the values obtained indicating very similar compositions for all the planets. This fact makes the system even more remarkable and helps to better understand the nature of these fascinating worlds. This study has just…

Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.

Green hydrogen gives Australia an opportunity to slash our emissions — and if we get this right, the impact could be nothing short of nation-building, argues business leader Andrew Forrest.

Twenty million years ago, the shores of northern Taiwan were sandstone sediments at the bottom of the sea, where 6-foot-long worms lurked in their burrows, waiting for unsuspecting prey to pass overheard. Now, a team of geoscientists have chronicled 319 trace fossils of those carnivorous marine worms, whose dens fossilized in the...

Just like on Earth, water on other planets, satellites, and even comets comes in a variety of forms depending on multiple factors such as pressure and temperature. Aside from the gaseous, liquid, and solid states we are accustomed to, water can form a different type of crystalline solid called clathrate hydrate. Although they look similar to ice, clathrate hydrates have actually small water-based cages in which…

Likely the most well-known result of the Earth's magnetic field are the Aurora Borealis and Australis (Northern and Southern Lights). When charged particles from the solar wind run into the Earth's magnetic field, they can occasionally elicit sp

SpaceX intends to launch tens of thousands of Starlink satellites, with lifespans of around 5 years, into low-Earth orbit. The goal is global internet access. Astronomers are concerned. Here's how to watch Wednesday's launch.

The end of the last ice age, around 12,000 years ago, was characterised by a final cold phase called the Younger Dryas. Scandinavia was still mostly covered in ice, and across Europe the mountains had many more, and larger, glaciers than today. There

NASA's groundbreaking New Horizons mission is revolutionising what we understand about outer space, but its latest finding has suggested that there might actually be a whole lot less out there than we first thought. Data from the New Horizons spacecraft, NASA's third interstellar mission, has shown that the universe is actually darker than previously estimated, …

More than 690 million celestial objects have been catalogued, photographed and are now available online for exploration by the public, thanks to an international research collaboration.

The outer planets - along with two other planets - revolve around a star about 10 billion years old. Scientists have discovered some ancient planets

Vanderbilt astrophysicists, led by Assistant Professor of Physics and Astronomy Stephen Taylor, are part of a group of researchers that may have found...
