Study suggests we reclassify the moon as a planet—reopening a centuries-old debate

Want Pluto back as a planet? This is the other consequence of Stern's proposal. We'd have well over 100 planets in the system.

That is unacceptable! That's 92 too many!

No kidding. Not so cool in the news, eh? It's worse than 92 too many. And our Moon is bigger than Pluto. So readmitting Pluto to the planet family, based upon Stern's criteria, also admits things that are moons, asteroids, etc.
You have to read their raving fine-print in Stern's loony proposal. I doubt that this will be accepted.

Meet some of the 'new' Stern candidates alongside a couple of the smaller old members. He wants to call them planets. Some of them (not just Pluto) have been called planets before. But he thinks this matches up with "people's intuition" concerning planets. No.

Every known round object in the solar system under 10,000 kilometers in diameter, to scale:

"Under a size cutoff of 10,000 kilometers, there are two planets, 18 or 19 moons, 1 or 2 asteroids, and 87 trans-Neptunian objects, most of which do not yet have names. All are shown to scale, keeping in mind that for most of the trans-Neptunian objects, their sizes are only approximately known."

Rare ‘ghost snow tsunami’ wave caught on camera

A photographer has captured a rare weather phenomenon that she’s described as a ‘ghost snow tsunami’.

The mirage happens when snow crystals, light and wind are perfectly aligned on the horizon.

Ariel McGlothin was hoping to capture some local wildlife in action when she went out to take some pictures in Kelly, Wyoming, but inadvertently witnessed an incredibly rare spectacle.

Standing before a huge wall of icy powder, a strange mirage began to form as the sun – aligned perfectly with the direction of the wind – began to highlight snow crystals moving in the cold wind, resembling a series of ghostly waves crashing against a shoreline.

A Lost Page of Notes on Einstein's 'Theory of Everything' Has Turned Up in Jerusalem
Image
A lost page of Albert Einstein’s handwritten notes and equations has turned up. The page, part of the appendix to a scientific journal article published in 1930, shows one of Einstein’s attempts to unite all the fundamental forces into a single set of equations, or a "theory of everything." (Credit: Copyright The Hebrew University of Jerusalem)

A never-before-seen page of Albert Einstein's handwritten notes and equations on the unified theory of physics has been discovered in an archive of Einstein manuscripts recently acquired by The Hebrew University in Jerusalem.

According to a statement from the university, the newfound page was part of an appendix that Einstein included with a scientific article on unified field theory — the long-sought theory that unites all the fundamental forces of nature into a single set of equations — which Einstein submitted to the Prussian Academy of Science in 1930.

Previously thought lost, the page of elegantly written notes has never been seen or studied since its original submission, according to the statement. [8 Ways You Can See Einstein's Theory of Relativity in Real Life]

The long-lost note turned up in an archive of 110 manuscript pages that The Hebrew University recently acquired from a private collector in Chapel Hill, North Carolina. Many of the new pages have never been displayed to the public before, including 84 pages of mathematical calculations written from 1944-48, plus a number of letters to Einstein's friends and family.
