The Universe Expands Far Faster Than Anticipated…

The Universe is accelerating

For a while now, astrophysicists have known that our Universe is expanding, and accelerating.  And much like the surface of a rubber balloon getting inflated, space is getting bigger, and bigger, and bigger… Continue reading The Universe Expands Far Faster Than Anticipated…

Large Asteroid Impacts Earth…

Five years after the Chelyabinsk asteroid impact, a three-in-a-century event happens again over the Bering Sea.  And almost no-one notices.  I say “no-one”… but the Earth is a planet under constant scrutiny. Continue reading Large Asteroid Impacts Earth…

Crimson Moon – A Total Lunar Eclipse

A meme showing Lance Corporal Jack Jones, from the fictional Home Guard platoon portrayed in popular British sitcom 'Dad's Army' uttering his familiar catchphrase: "Don't Panic!" with a total eclipse of the Moon appearing crimson red in the background.The Motion of Celestial Spheres

The Universe never sleeps.  Every now and then, the night sky presents us mere mortals with some heavenly spectacle.  A Bonnie Tyler moment.  This Friday, the Moon will enter the catwalk dressed in red to accomplish its otherwise normal nightly travel around the Earth.  For one night only.  A strange and rare celestial sight at dusk – a total lunar eclipse.    Continue reading Crimson Moon – A Total Lunar Eclipse

Negative mass has always been theoretically possible, and the concept has finally made it from a mathematical idea on paper to a reality achieved in the lab.  Scientists at Washington State University have created a fluid with negative mass.  Continue reading The Bizarre Behaviour of Negative Mass

The Sentinel satellite program was designed to replace the older Earth observation missions, which have reached retirement or are nearing the end of their operational life span.  The satellite array will ensure a continuity of data, so that there are no gaps in ongoing studies.

Arecibo and the Great Silence – Where We Talk About a Parrot Named Alex

An aerial photograph showing the Arecibo Observatory telescope, with a picture of Alex at the forefront. The dish reflector of the telescope is built into a valley in the landscape, and the feed antenna is suspended by cables above it. Since the reflector can't be moved, the telescope is steered to point at different regions of the sky by moving the feed antenna $ ($in bell shaped dome$ )$ along on a curving track. The dome shields the feed antenna from interfering radio signals. Collage: NaturPhilosophieArecibo – What a Dish!

The Arecibo observatory is a very large radio telescope located in Puerto Rico.  In 1974, astronomers used it to broadcast a message into outer space intended to demonstrate human intelligence.  Why are we so interested in finding intelligence in the stars, and yet so deaf to the many species who manifest it here on Earth?

2016: Another Year in Cutting Edge Science

A photo-montage showing pictures of the recent scientific developments of the year 2016. From Major Tim Peake's extraordinary space adventure, to the discovery of the missing elements in the Periodic Table, and the gravitational wave detection from a merger of black holes far away in outer space... Collage: NaturPhilosophieYou Spin Me Right Round…

Just over a century ago, Einstein proposed the existence of waves in the spacetime continuum – the logical deduction from his Theory of General Relativity.  In February 2016, scientists finally announced the detection of those “ripples” in gravity, using the technique of laser interferometry.  Continue reading 2016: Another Year in Cutting Edge Science

Temperature Inversions, City Pollution and Defunct Jet Engines

Temperature inversions are meteorological phenomena which can occur over busy cities under particular environmental conditions.  Retired jet engines could be used as “virtual chimneys”, and draw upwards the resulting smog that clouds the air over some of the World’s most polluted cities.  Continue reading Temperature Inversions, City Pollution and Defunct Jet Engines

Erm…No.  Not Mona Lisa!  (Rolls eyes.)  Think again!!  This is LISA – the Lisa Pathfinder satellite, the key element for a grand new project: a space-based gravitational observatory.  Continue reading Hunting Ripples in the Fabric of Space-Time – The Trials and Tribulations of LISA

The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO

An animation illustrating two colliding and merging black holes in outer space.

Black Holes Far Ago Have Been Causing a Stir…

You know how when you throw a rock into a pool, that makes ripples in the water?  And how Einstein once upon a time predicted that the very mass of stars and planets should warp spacetime?  Although we have had a justified inkling that Einstein was right for quite some time, we had never before detected such a phenomenon.  Until THIS happened… Continue reading The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO

Name: Tim Peake Job: Space Electrician

A selfie photograph taken by British astronaut Major Tim Peake of himself during his historic first space walk outside the International Space Station on 15 January 2016. The British Union flag is visible on the left shoulder of his pressure suit, as well as a view of the Earth being reflected in his visor. Spaceman, I always wanted you to go into space, man!

After nearly five hours in space, British astronaut Tim Peake completed his first spacewalk, at 17:31 GMT on Friday 15 January.  Intended to last over six hours, the space walk was cut short after his US colleague Tim Kopra reported a water leak in his helmet.

With his wind-swept mane, the inimitable Richard Feynman looked devilishly handsome. And he darn-diddly knew it too! As for Fritz Haber, Rosalind Franklin and Neil deGrasse Tyson, they were the original hipsters. That’s according to BuzzFeed anyway… Continue reading Proving that Physicists were the Original Hipsters

Just a Second…

A close-up photograph of an analog clock showing the hands just reaching the hour.What Does a Second Look Like?

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?
