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?
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.
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.
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.
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.
