Move Over Pluto, Astronomers Say There's a New Planet in Town Ten years ago, astronomer’s shrunk the solar system by removing Pluto from the list of real planets. Now the solar system is getting bigger again. Artistic rendering of the distant view from Planet Nine back towards the sun. The planet is thought to be gaseous, similar to Uranus and Neptune.

One author of today's article is Mike Brown, who also wrote the book How I Killed Pluto and Why It Had It Coming .

Pluto Demoted Last year, astronomers at Cal Tech discovered an object they called Xena--even bigger than Pluto, and also orbiting around the Sun. That set off an astronomical controversy. Are there really 10 planets? Today, the International Astronomical Union said, "No." Xena isn't a planet at all, and neither is Pluto. Planetary astronomer Mike Brown led the CalTech team that discovered Xena . (An extended discussion on this subject was originally aired earlier today on To the Point.)
Pluto, Planet or Plan Not? Since Pluto's discovery in 1930, there have been nine planets in the solar system, but a year ago, scientists at the California Institute of Technology said there were ten. An object they called Xena turned out to be bigger than Pluto and was also orbiting around the Sun. That set off an astronomical controversy that wasn't resolved until today, thanks to the International Astronomical Union . Planetary scientist Mike Brown led the Cal Tech Team that discovered Xena.
Trump, the GOP and the rule of law Conservatives — and some Republicans — are criticizing the President for "the mess he made" in firing FBI Director James Comey. We hear about a potential successor, the possibility of "obstruction of justice" and the constitutional separation of powers.
Trump's Russia ties intensify with Comey firing Acting FBI Director Andrew McCabe contradicted the Trump White House today, insisting the Bureau had not lost faith in former Director James Comey. He promised to notify the committee of any interference into investigation of the Trump campaign's contacts with Vladimir Putin's Russia. What do we know about those contacts… and how they relate to Trump's business interests and those of his family?
Trump fires FBI Director James Comey Vice President Mike Pence took the Administration's lead today in explaining why the President fired the Head of the FBI, saying, "The president made the right decision at the right time." Trump's action is being compared to the so-called "Saturday Night Massacre" that led to President Richard Nixon's resignation in 1973.
