Let’s talk about size… 😉 How big are the objects floating in our Universe and how big can they get? Starting with a “big” object, our very own Moon… Embark on a tour of space… A tour of our Universe…

Look into my eyes. The eyes, the eyes. Not around the eyes. Don’t look AROUND the eyes. Look INTO my eyes. The eyes… [click] You’re not under! But… Can you read my mind?

Taking a radically different experimental approach, EPFL scientists were able to take the first ever snapshot of light behaving simultaneously both as a wave AND as a stream of particles. You need light to take a photograph. But how do you take a photograph of light?

1/60 minute. 1/3,600 hour. 1/86,400 day. 1/1 hertz. The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of a 133 55Cs caesium isotope corresponds to one second. But what does it look like? And where might you find a second?

Deep down, in huge subterranean caverns… Underneath the Franco-Swiss border… 300 feet underground… lies a beast of unprecedented power… and mystery. The Large Hadron Collider (LHC) that man summons to explore the uncharted corners of the sub-atomic realm… After two years of a deep slumber, the mighty beast has awoken…

Still in its early stages, El Niño has the potential to cause extreme and even devastating weather around the World. According to climate graphs, we have reached a 0.6 value for the ENSO. It’s a 60% probability. El Niño is now officially back.

How could the humble Tortoise ever beat legendary Greek champion, Achilles, in a race to the finish? And what about that time when the champion of the animal kingdom simply ridiculed his next-door neighbour aka the Hare?

Ever since the early days of human space travel, back in the 1960s, astronauts have run experiments involving plants in space. Over a million seeds of rocket (two kilograms of rocket seeds) are shortly due to take off from Florida, bound for the International Space Station, as part of British ESA astronaut Tim Peake’s six-month Principia mission.

The Standard Model of Particle Physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces, providing precise predictions for measurable quantities that can be tested experimentally. Here’s the latest!! It’s hot!!! It’s exciting!!! At least, if you’re a particle physicist…

Expedition 43 astronaut Samantha Cristoforetti snapped this photograph of herself wearing the Starfleet uniform from TV series “Star Trek: Voyager” aboard the International Space Station, and posted it on her Twitter account @AstroSamantha last month.

About four billion people on our planet actually live in places with no house numbers, no street names, or without anything that constitutes a proper address. They are effectively off-the-map, with no voting rights or access to public utilities. A new company called What3Words proposes to revolutionise that…

Be under no illusion. You saw the sign: “Pickpockets are operating in this area”. You reacted. Instantly. The first thing you did was to check your pockets or handbag for signs of financial solvability. All is well. You relax. Only now, you’ve become the “mark”… because you’ve just given away precious information about the location of your valuables around your body.

Surrounding the town of El Ejido, Almeria Province, southern Spain is a sea of greenhouses, stretching for tens of kilometres, visible from space. Millions of tons of vegetables are exported from there to other European countries and further parts of the World. Along the Mediterranean coast, tourism flourishes, fuelling a booming real estate economy…
Should you ever have wondered what the Higgs boson sounds like… It’s… “AS LOUD AS A RIFF BY JOE SATRIANI. WHAT?! IT’S AS LOUD… AS A…” Oh, wait!! Here it is.

Geothermal energy prospectors have long used gravity meters in their search for the right subsurface characteristics. But these have been point measurements. GOCE now provides this information across the World at a resolution never before achieved on that scale.

This is the Jasper Project. Over 325,000 photovoltaic panels capable of producing 180,000 MWh of clean energy every year and support the needs of almost 80,000 households. More and more solar farms are being built across Africa. Solar energy is on the rise.

“Dark matter?” You cannot see it. But there is something there. As for what it is, it’s anybody’s guess! Dark matter does not interact with light. At all. Which makes it difficult to detect. “But if you cannot see it? How do you know it is in fact there?” Well, it does interact with gravity, and as it does so it bends the path of any light ray passing nearby...

A ground-breaking one-year space mission involving twin astronauts Mark and Scott Kelly should help doctors, scientists and mission planners better understand the physical and psychological impacts of a long-duration spaceflight.

Right on cue, day turned into a sudden eerie twilight as a great swathe of the Earth’s surface quickly plunged into transient darkness. The magic number is 400. For many observers, weather conditions were far from ideal. Clouds obscured the much awaited spectacle of the 2015 eclipse. Thankfully, alternatives were available to astronomers keen not to miss the big event…
Continue reading 400 – Anatomy of a Solar Eclipse
On 20th March 2015, the Moon will pass in front of the Sun and exactly block out most of its light. It will be the first total solar eclipse of the 21st century that is visible from the northernmost regions of Europe…

This mesmerising image of the Northern Lights over Scotland was captured by Baltimore-born NASA astronaut Terry Virts, a member of Expedition 42 from the International Space Station earlier this week, as it drifted over Europe.

What happened at time T = 0? is still anybody’s guess. At least, earlier observations of Planck’s radiation had suggested the first generation of stars were bursting into life by about 420 million years after the Big Bang. However, scientists from Europe’s Planck satellite mission now say the first stars lit up the Universe later than was previously thought…
At the beginning of the 20th century, the discovery of the radiometric “clock” revolutionised our understanding of the Earth’s deep history, confirming what geologists had been claiming for decades. Nevertheless, newer and more accurate dating methods posed further problems in themselves. After all, how do we know our Earth is 4.5 billion years old, and not a mere few thousands of years as suggested by the Bible?
