Strange star system may hold first evidence of an ultra-rare 'dark matter star'

In a distant star system, a sunlike star orbits an invisible object that may be the first example of a 'boson star' made of dark matter, new research suggests.

Astronomers long thought that a peculiar star system observed by the European Space Agency’s Gaia satellite was a simple case of a star orbiting a black hole.

But now, two astronomers are challenging that claim, finding that the evidence suggests something far stranger: Possibly, a never-before-seen type of star made of invisible dark matter. Their research, which has yet to be peer-reviewed, was published April 18 on the preprint server arXiv.

The system itself consists of a sunlike star and, well, something else. The star weighs a little less than the sun (0.93 solar mass) and has roughly the same chemical abundance as the sun. Its mysterious companion is much more massive — around 11 solar masses. The objects orbit each other at a distance of 1.4 astronomical units, about the distance at which Mars orbits the sun, making a complete orbit every 188 days.

In 2004, NASA pointed the Hubble into a very small section of space and the result was amazing…

Ok so Haumea, a dwarf planet beyond Pluto, spins so fast it gets elongated like this. This is just what it looks like. Something deeply unsettles me looking at it. Terrifying.

On 26 September 2014 Planet Earth’s Sun “erupted with a twisted blob of plasma that was part of a coronal mass ejection blasted into space…This would not appear to be directed towards Earth….The material seen here is ionized Helium at 60,000 degrees C [108,032 degrees Fahrenheit].” [1228 x 1228] by trot-trot
