Paul Mason and his student James Vesper, astronomers with New Mexico State University, presented the results of simulations on the mysterious planet at this year's American Astronomical Science meeting. The simulations show that a planet of Nine's size and distance from the Sun would likely be a rogue planet. Rogues are planets not beholden to a star's gravity, interstellar nomads who freely wander through space.
When rogues enter the gravitational pull of a star, according to Mason and Vesper, they can be captured and remain in the star's orbit. This is what occurred in 40 percent of their simulations, and what they believe was the fate of Planet Nine. The rest of the time, a rogue enters a solar system and leaves soon after. Mason and Vesper believe rogues to be far more abundant than previously thought, but rare in our own solar System.

It was 1:30 a.m. local time in northern Ontario on Jan. 6 when Elzinga spotted the phenomenon.
"When I first saw these light beams shooting through the sky from my bathroom window, I was sure they were the northern lights," Elzinga told Live Science in an email. "I was able to capture these images both because the lights were so bright and pronounced and because I'm a bit of an amateur photographer." That experience, he said, led him to use "the manual settings on my phone to adjust the time the aperture was open to 8 seconds."
Elzinga said he wasn't aware of this light-pillar phenomenon until he saw it firsthand.
Ice from high altitudes explains the pillars that Elzinga saw, NASA said. During some cold, wintry nights, flat ice crystals that normally reside higher up in the atmosphere come fluttering closer to the ground, according to NASA. These whimsically wobbling ice crystals are sometimes referred to as crystal fog. When the crystals reflect ground lights from nearby cars and other bits of civilization, the result can be glorious: columns of light called "light pillars."

"Flying above the clouds has never looked this good!" read the tweet. "These incredible cloud formations were seen on board VA714 from Perth to Adelaide.The mysterious white fluffy rows are examples of wave clouds, the most famous of which — the Morning Glory — is found only in Northern Australia.
While these invisible waves in the sky occur elsewhere, it's the cloud accompanying it which is so rare.Their distinctive fat sausage shape is due to water vapour rising to form the cloud then evaporating back again to the ground.
"Wave clouds can form anywhere on the continent but they are only called the Morning Glory when they form across the Gulf of Carpentaria, Neil Bennett, a Western Australian spokesman for the Bureau of Meteorology told news.com.au.
Comment: Another rare morning glory roll cloud was sighted in Queensland, Australia last July.

Several WHNT News 19 viewers, including Ramona Edwards and Tressi Downs, shared pictures with us of a large ring around the sun.
This optical feature is called a 22-degree sun halo.
Earthsky.org explains it very simply:
Halos are a sign of high thin cirrus clouds drifting 20,000 feet or more above our heads. These clouds contain millions of tiny ice crystals. The halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals.

The first of the loud sounds to draw widespread attention on social media was a Thursday night, Dec. 1, around 11:45 p.m. Residents heard it across the entire Carrollton area from St. Charles Avenue to South Claiborne, between Joliet and Pine, and many said it sounded like it came from the river, with sirens following.
"It was louder than I'm used to hearing a transformer sound and it seemed to reverberate for a bit," a woman who lives near Cohn and Dante posted on the Nextdoor social media network. "Really strange.It was extremely loud! And deeper sounding than the gunshots I'm (sadly) used to hearing," a resident at Panola and Cambronne replied.
The sound repeated itself again the night of Tuesday, Dec. 6, around 7 p.m. — early enough that it attracted even wider attention. In that second case, a number of residents reported that their homes shook, and some even said they thought they saw a corresponding red flash in the sky.

The video, posted to YouTube by Ryatus Recordings, shows triplet suns on the horizon Tuesday afternoon over the town of Detroit Lakes.
"I was lucky enough to grab a quick shot of this awesome sun dog on the way home from work," the uploader wrote.
Sundogs, also known as phantom suns, occur when the light from the sun reflects from ice crystals gathered in the atmosphere.

Once thought to be mere curiosities, some polar stratospheric clouds (PSCs) are now known to be associated with the destruction of ozone. Indeed, an ozone hole formed over the UK in Feb. 2016 following an outbreak of ozone-destroying Type 1 PSCs.
These clouds really are as amazing as they look in Fokke's photo. They have much more vivid colors than ordinary iridescent clouds, which form closer to Earth in the troposphere. Once seen, a stratospheric cloud is never forgotten.
