It's an asteroid! No, it's the new smallest dwarf planet in our solar system - CNN

(CNN) A large asteroid could be reclassified as a dwarf planet -- which could make it the smallest in the solar system -- after new research revealed its shape, astronomers said on Monday.

Lessons from scorching hot weirdo-planets

Illustration of a hot Jupiter planet in the Messier 67 star cluster. Hot Jupiters are so named because of their close proximity — usually just a few million miles — to their star, which drives up temperatures and can puff out the planets.

Hot Jupiters were the first kind of exoplanet found. A quarter-century later, they still perplex and captivate — and their origins hold lessons about planet formation in general.

In 1995, after years of effort, astronomers made an announcement: They'd found the first planet circling a sun-like star outside our solar system! It's an asteroid!

But that planet, 51 Pegasi b, was in a quite unexpected place — it appeared to be just around 4.8 million miles away from its home star and able to dash around the star in just over four Earth-days. Our innermost planet, Mercury, by comparison, is 28.6 million miles away from the sun at its closest approach and orbits it every 88 days.

NASA chief says 'Pluto should be a planet' | Fox News

“I am here to tell you, as the NASA Administrator, I believe Pluto should be a planet,” he said, to applause during a wide-ranging speech at the International Astronautical Congress in Washington D.C. Friday.

Bridenstine later responded to a question on his Pluto stance by citing its buried ocean , its moons and its multilayered atmosphere. “I like there being nine planets, how about that?” he added.

Pluto lost its planet status in 2006 when it was controversially demoted to “dwarf planet” by the International Astronomical Union.

This is not the first time that Bridenstine has voiced his desire to see Pluto become a planet again. "You can write that the NASA administrator declared Pluto a planet once again! It's an asteroid!

It's been over a decade since Pluto was relegated from being the ninth planet in the solar system and deemed to be a mere "dwarf planet" by astronomers, but NASA administrator Jim Bridenstine says he wants it re-instated. 

"I am here to tell you, as the NASA administrator, I believe Pluto is a planet," said Bridenstine during a keynote on the final day of the International Astronautical Congress in Washington, D.C. on October 25.

Many things are taking place:

Why a rocky planet with three suns has astronomers' attention

"We can stare at it using a spectrograph," said Winters, lead author on "Three Red Suns in the Sky: A Transiting, Terrestrial Planet in a Triple M Dwarf System at 6.9 Parsecs," published in the Astronomical Journal . "It's one of the best examples of a rocky planet that might have an atmosphere that we can study to see what it's made of."

For the next few months, before the planet is hidden from our view behind the sun, Winters and her collaborators will gather data and monitor it. Using data from the Giant Magellan Telescope in Chile, as well as NASA's Hubble and Spitzer space telescopes, the team will try to measure the planet's mass and determine whether it is indeed a rocky, as opposed to gaseous, planet!

They believe the asteroid Hygiea should actually be classified as a dwarf planet.!! The mass of the new find matters, she explained, because it correlates with how thick any atmosphere is expected to be. And if there is none—if, perhaps, one has been burned off by radiation—scientists will see whether one is sprouting, perhaps replenished by gases emitted by the crust.

Rogue, Starless Planets May Circle Black Holes | Space

Thousands of planets may form and orbit around the kind of supermassive black holes found in the cores of most, if not all, galaxies, a new study finds.

"Planets are not only orbiting around stars, but also around supermassive black holes," study lead author Keiichi Wada, an astrophysicist at Kagoshima University in Japan, told Space.com.

When new stars form, the clouds of gas and dust around them collapse to form disks. Previous research suggested that planets originate within these "protoplanetary disks" as gravity pulls clumps of matter together into larger masses; the Atacama Large Millimeter/submillimeter Array (ALMA) has mapped 20 such planet-building disks around nearby stars to extraordinary detail.

However, stars are not the only astronomical bodies surrounded by disks of gas and dust. Such disks also often surround supermassive black holes with masses that are millions to billions of times that of Earth's sun. This led Wada and his colleagues to investigate whether planets might form around such black holes.
