An oddball solar system discovered not too far from our own is forcing astronomers to reexamine their ideas about how planets get created.
In the journal Science, researchers report they detected a small, dim red dwarf star, about 30 light-years from Earth, being tugged by the gravity of what must be a huge, Jupiter-like planet.
"It's a very large planet, for such a small star," says Juan Carlos Morales , an astrophysicist at the Institute of Space Studies of Catalonia in Barcelona who was part of the research team.
It's so big, he says, that its existence can't be explained by the conventional wisdom about how solar systems develop.

Most Extreme 'Hot Jupiter' Alien Planet Completes 1 Orbit Every 18 Hours | Space
Giant alien worlds known as hot Jupiters get scorchingly close to their host stars, and now astronomers have discovered the most extreme version of such planets to date — one that zips around its star in a little more than 18 hours, a new study finds.
This exoplanet's orbit is likely decaying enough for scientists to actually measure it over the coming decade, researchers added.
In the past two decades or so, astronomers have confirmed the existence of more than 4,000 worlds outside of Earth's solar system! Newly Discovered Planet Challenges Astronomers' Notions Of ...www.npr.org /2019/09/26/764247918 Newly Discovered Planet Challenges Astronomers ' Notions Of How Planets Form A surprisingly large planet orbiting a small star defies the conventional wisdom about how planets are born. But a...!! These discoveries have revealed that some of these exoplanets , such as hot Jupiters, gas giants that orbit their stars closer than Mercury does the sun, are very different from those seen in Earth's solar system.

Lava Flows on Venus Suggest That the Planet Was Never Warm and Wet - Universe Today
Venus is often referred to as " Earth's sister planet ", owing to the number of similarities between them. Like Earth, Venus is a terrestrial (aka. rocky) planet and it resides with our Sun's Circumstellar Habitable Zone (CHZ). And for some time, scientists have theorized that billions of years ago, Venus had oceans on its surface and was habitable – aka. not the hot and hellish place it is today.
However, after examining radar data on the Ovda Fluctus lava flow , a team scientists at the Lunar and Planetary Institute concluded that the highlands on Venus are likely to be composed of basaltic lava rock instead of granite! Giant exoplanet around tiny star challenges understanding ...The planet was found orbiting the nearby red dwarf star GJ 3512. This discovery challenges scientists' very understanding of how planets form: low-mass stars should have less available material to ...!! This effectively punches a hole in the main argument for Venus having oceans in the past, which is that the Ovda Regio highlands plateau formed in the presence of water.
The study that describes their findings (and includes a new map of the highlands plateau) recently appeared in the Journal of Geophysical Research: Planets . The study was conducted by members of the LPI with the assistance of undergraduate student intern Frank Wroblewski (from Northland College), and Prof. Tracy K.P. Gregg of the University of Buffalo.

Saturn Becomes 'Moon King' with 20 New Discoveries
Jupiter used to hold the record for most moons orbiting around it. It has 79. But scientists in the United States have announced the discovery of 20 new moons around Saturn! 'Monster' planet discovery challenges formation theory ...www.sciencedaily.com ...The existence of the 'monster' planet , ' NGTS-1b ', challenges theories of planet formation which state that a planet of this size could not be formed around such a small star. According to these...!! That gives the planet a new total of 82 moons.
The researchers made the discovery using the powerful Subaru telescope in Hawaii. They gathered information over a period of several years.

Scott Sheppard led the research team. He is with the Carnegie Institution for Science in Washington, D.C. "Saturn is the moon king," Sheppard told Reuters news agency.
The discovery was announced last week by the International Astronomical Union's Minor Planet Center . The center is responsible for identifying all the world's minor planets, comets and "outer natural satellites." The organization also measures the orbital movements of such objects.
Humans will not 'migrate' to other planets, Nobel winner says
"If we are talking about exoplanets, things should be clear: we will not migrate there," Mayor told AFP near Madrid on the sidelines of a conference when asked about the possibility of humans moving to other planets.
"These planets are much, much too far away. Even in the very optimistic case of a livable planet that is not too far, say a few dozen light years, which is not a lot, it's in the neighbourhood, the time to go there is considerable," he added.

Using custom-made instruments at their observatory in southern France, Mayor and Queloz in October 1995 discovered what had previously only existed in the realm of science fiction—a planet outside Earth's solar system.
Mayor was a professor at Geneva University and Queloz was his doctorate student, when they made the discovery which started a revolution in astronomy!
