Could a tiny spacecraft sail on a beam of light across the galaxy?

We don’t know much about the closest star system to our own. So let’s aim an absurdly powerful laser beam at it and see what happens. In the most basic sense, that’s what the Breakthrough Starshot project is about —…

Is the Random Transiter weirder than Tabby’s Star?

Move over, Tabby’s Star. The Random Transiter may now be the weirdest star in the galaxy. Kepler data revealed 28 transits in front of this star in 87 days. What caused them? Multiple planets? A disintegrating planet? Alien megastructures?

Success with a new theory of gravity

Supercomputer simulations of galaxies show that Einstein’s general theory of relativity might not be the only way to explain how gravity works or how galaxies form. The new Chameleon Theory is a possible alternative.

Will planetary low tide force regular sunspot sync-ups?

No, it’s not pseudoscience. Does a regular alignment of planets make a strong-enough tug to regulate the sun’s 11- and 22-year cycles? Read more in this story via Eos – a source for news and perspectives about Earth and space science – from the American Geophysical Union.

Today in 2003: Opportunity blasts off to Mars

NASA’s Opportunity rover spent some 15 years exploring Mars. It surpassed all expectations for its endurance and longevity, to become one of the most successful planetary missions. Then it went silent.

Someone may have forgotten to turn off the TV at the other end of the universe. Or maybe someone has sent us an emoji from a faraway mothership. In other words, we don’t have a clue what transmitted the single…

Do organic crystals create ‘bathtub rings’ around Titan’s lakes and seas?

Scientists have been trying to figure what creates the so-called “bathtub rings” around lakes and seas on Saturn’s large moon Titan. Now they may have an answer: unusual organic crystals not found on Earth.

Who needs fireworks when you have the stars?
