There's Evidence Volcanoes Are Active on Mars, Raising Chances of Recent Habitability

A new, close study of volcanic features on the surface of the red planet has found that a lava deposit on the Elysium Planitia appears to be very recent indeed - as in, within the last 50,000 years.

On geological timescales, that's shockingly short. And it could mean that Mars was potentially habitable just as recently, with parts of it similar to regions of volcanic activity in glacial areas such as Iceland, where various forms of extremophile bacteria thrive.

‘It’s like the embers in a barbecue pit.’ Nuclear reactions are smoldering again at Chernobyl

Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world’s worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. “It’s like the embers in a barbecue pit,” says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own—or require extraordinary interventions to avert another accident.

Uncontrolled Rocket Segment Finally Re-Entered Earth's Atmosphere

A large segment of a Chinese rocket re-entered the Earth's atmosphere and disintegrated over the Indian Ocean on Sunday, the Chinese space agency said, following fevered speculation over where the 18-tonne object would come down.

Voyager 1 Is Detecting a 'Hum' of Plasma Waves in The Void of Interstellar Space

Voyager 1 has left the Solar System - and it's finding that the void of space is not quite so void-like, after all.

In the latest analysis of data from the intrepid probe, from a distance of nearly 23 billion kilometers (over 14 billion miles), astronomers have discovered, from 2017 onwards, a constant hum from plasma waves in the interstellar medium, the diffuse gas that lurks between the stars.

TRUE Limits Of Humanity – The Final Border We Will Never Cross

Is there a border we will never cross? Are there places we will never reach, no matter how hard we try? It turns out, there are. Even with sci-fi technology, we are trapped in a limited pocket of the Universe and the finite stuff within it. How much universe is there for us and how far can we go?

NASA's Probe With Its Precious Bennu Sample Is Finally Returning to Earth!

A spacecraft carrying around 56.70g of dust from the surface of an asteroid is on its way back to Earth.

The spacecraft, called OSIRIS-REx, launched its thrusters for 7 minutes on Monday to leave the asteroid Bennu.

NASA expects the sample will land in the desert in Utah on September 24, 2023.

Incredible Images Reveal a Single Moment on Jupiter in Different Wavelengths of Light

We all know what Jupiter looks like, with its vanilla and butterscotch ice-cream bands of counter-rotating cloud, and the iconic red storm raging in the southern hemisphere.

But that's only how Jupiter looks in optical wavelengths, though. When imaged in wavelengths beyond the limits of human vision, Jupiter appears differently. In infrared, thermal emission glows brightly, with cooler regions duller red (a bit like lasagna); in ultraviolet, soft, cotton-candy pastels show us different altitudes...

Ultra-Fast Air And Space Travel Just Got Closer With a Hypersonic Detonation Test

A never-ending detonation could be the key to hypersonic flight and space planes that can seamlessly fly from Earth into orbit. And now, researchers have recreated the explosive phenomenon in the lab that could make it possible.

Detonations are a particularly powerful kind of explosion that move outward faster than the speed of sound. Now, a team from the University of Central Florida has created an experimental setup that lets them sustain a detonation in a fixed position for several seconds, which the researchers say is a major step toward future hypersonic propulsion systems.

Mysterious Wobbles in Saturn's Rings Reveal Clues About Its 'Fuzzy' Interior

What's in a gas giant?

No, really. The interiors of Jupiter and Saturn are actually quite difficult to probe. But Saturn's uniquely glorious and extensive ring system is proving to be an excellent tool for figuring out the densities deep below its thick cloud layers, right down to the core.

That core, according to a new analysis of 'wobbles' in Saturn's innermost main ring, likely isn't a dense ball of nickel and iron, as currently thought, but a "fuzzy" region of mostly hydrogen and helium, with a gradual mixing of heavier elements, extending to 60 percent of the planet's radius and containing around 17 Earth masses of ice and rock...

Is It Possible to Get Too Much Sleep? Here's What Scientists Think

Sleep has a major impact on our health and wellbeing. Busy lifestyles often make it difficult to sleep as much as we would like to. Not sleeping enough affects our mood, ability to focus, and risk of many medical conditions.

We are often encouraged to sleep more, but can sleeping too much also be unhealthy?

All humans but one

After the most famous voyage of modern times, it was time to go home. After proving that humanity has the ability to go beyond the confines of planet Earth, the first humans to walk on another world -- Neil Armstrong and Buzz Aldrin -- flew the ascent stage of their Lunar Module back to meet Michael Collins in the moon-orbiting Command and Service Module.

Pictured here on 1969 July 21 and recently digitally restored, the ascending spaceship was captured by Collins making its approach, with the Moon below, and Earth far in the distance.

It is said of this iconic image that every person but one was in front of the camera.

Take a Tour of The Tiny, Wonderful World of Microfluidics

When you think of micro- or nanotechnology, you likely think of small electronics like your phone, a tiny robot or a microchip.

But COVID-19 tests – which have proven to be central to controlling the pandemic – are also a form of miniaturized technology. Many COVID-19 tests can give results within hours without the need to send a sample to a lab, and most of these tests use an approach called microfluidics.

Everything from pregnancy tests to glucose strips to inkjet printers to genetic tests rely on microfluidics. This technology, unbeknownst to many people, is everywhere and critical to many of the things that make the modern world go round.

A Common Earth Molecule Is Detected For The First Time in an Exoplanet's Atmosphere

The molecule hydroxyl (HO) is common on Earth, but astronomers have not yet determined how abundant it is on other worlds. For the first time, astronomers have conclusively detected it in the atmosphere of an ultra-hot Jupiter, WASP-33b.

WASP-33b is a strange exoplanet. 400 light-years away from us, the planet is known as an ultra-hot Jupiter: it's a gas giant that orbits its host star closer than Mercury does to our own Sun.
