Why Are Stars Star-Shaped?

Our sun is spherical, so why is it that other stars look… star-shaped in the night sky? Actually, it’s all down to the quirks of light and your (imperfect) eyes.


Astronomers Discover Farthest Stars In The Mysterious Milky Way Halo

A team of astronomers led by John Bochanski has found the farthest stars in our galaxy in the mysterious Milky Way halo, a rare discovery that may change our understanding of the formation of our galactic home. They’re so far away that, if you took a photo of the Milky Way from their orbit, it would look like the image above.


The Brightest Star In The Sky As You've Never Seen It Before

It might look like a drunken rainbow, but you’re actually looking at a view of Sirius, the brightest star in the night sky, as its light gets refracted by our atmosphere. Usually when you gaze upwards, the stars in the sky appear to twinkle. In fact, that’s a results of the light passing through our skies, which causes the rays to be refracted and change colour subtly by the time we see them.


First Ever 360-Degree Timelapse Bends Space And Mind

I’ve never seen anything like this stunning 360-degree time-lapse videos by photographer Vincent Brady. I think it’s the first one ever. He made them using a multiple camera 360-degree timelapse panorama after years spent experimenting and customising his kit. Incredible.


Dying Sun-Like Stars Contain Molecules Vital For Making Water

New observations by the European Space Agency’s Herschel space observatory have revealed that the burning embers of sun-like stars at the end of their lives actually contain molecules vital for the creation of water.


No, This Isn't The Eye Of Sauron

Briefly: It’s an amazing image of the ringed star HR 4796A, captured by the new Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument at the Very Large Telescope atop Cerro Paranal in Chile. The newly installed SPHERE filters out light to acquire exceptionally sharp images like these — unlike any telescope before it. [ESO via New Scientist]


These Are The Most Complete Pictures Yet Of The Sun's Atmosphere

You’re looking at the most complete photograph yet taken of the sun’s atmosphere — and it reveals complex patterns of expanding bubbles and mushrooms of matter, which are thought to cause the solar winds that the star spits out toward the rest of the solar system.


The Largest Yellow Star Ever Could Almost Devour The Whole Solar System

A team of astronomers peering through Chile’s Very Large Telescope just realised that HR 5171 A, a massive star in the Centaurus constellation, is actually twice as big as previously thought. They already thought it was pretty big — but it’s actually the biggest yellow star they have ever seen.


New Hubble Trick Will Change Our Perception Of The Observable Universe

Scientists have found a way to use the Hubble Space Telescope as an extremely precise galactic tape measure, multiplying our previous capabilities by 10. This increase will result in a more accurate understanding of the size of the observable Universe. plus new insight into the mysterious force known as dark energy.


Every City Deserves Space Murals This Gorgeous

Space, the final frontier… for street art. No, we’re not quite ready to tag the International Space Station, but a pair of artists in San Francisco is working on bring space down to Earth with a series of murals depicting everything from constellations to nebulae. And, boy, are they pretty.
