The Milky Way Through The Trees

My first photo of the Milky Way. (It was actually my 26th attempt. Practice makes perfect.) #bluemountains #astrophotography 🌠 (at Blue Mountains National Park)

Hale-Bopp: The Great Comet of 1997 : Only twenty-five years ago, Comet Hale-Bopp rounded the Sun and offered a dazzling spectacle in planet Earth’s night skies. Digitized from the original astrophoto on 35mm color slide film, this classic image of the Great Comet of 1997 was recorded a few days after its perihelion passage on April 1, 1997. Made with a camera and telephoto lens piggy-backed on a small telescope, the 10 minute long, hand-guided exposure features the memorable tails of Hale-Bopp, a whitish dust tail and blue ion tail. Here, the ion tail extends well over ten degrees across the northern sky. In all, Hale-Bopp was reported as visible to the naked eye from late May 1996 through September 1997. Also known as C/1995 O1, Hale-Bopp is recognized as one of the most compositionally pristine comets to pass through the inner Solar System. A visitor from the distant Oort cloud, the comet’s next perihelion passage should be around the year 4380 AD. Do you remember Hale-Bopp? via NASA

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.
