A distant world about 40 times more massive than Earth may be the remnant core of a giant planet, or a giant planet in the making whose growth stalled, a new study reports.
These findings may help shed light on what the mysterious cores of giant planets look like, researchers said.
Scientists investigated the exoplanet TOI-849b, which NASA's Transiting Exoplanet Survey Satellite (TESS) first detected in 2018 and whose existence the La Silla Observatory in Chile later helped confirm. This alien world orbits the sunlike star TOI-849 about 730 light-years from Earth.

'Oumuamua might be a shard of a broken planet | Science News
The solar system's first recorded interstellar visitor has a new proposed origin story. The enigmatic celestial object known as 'Oumuamua might be a shard of a planet ripped apart by its star's gravity , researchers suggest April 13 in Nature Astronomy .
Ever since 'Oumuamua showed up in our solar system in 2017, astronomers have struggled to explain its origin , suggesting that it might be a wayward asteroid, a comet or even an alien spacecraft ( SN: 2/27/19 ).

Beginners will enjoy the user-friendly features of the Celestron's PowerSeeker 127EQ. This telescope has been designed with a blend of value, quality, power, and user-friendly features to enhance the experience for first-time telescope users. High-quality and affordable are two features that don't usually go together. Luckily, the Celestron - PowerSeeker 127EQ provides both! The 3x Barlow lens helps in tripling the magnification power of the included 20mm and 4mm eyepieces.

Supercomputer Simulations Illuminate the Origins of Planets
Astronomers believe that many planets – including our own solar system – emerged from giant disks of gas and dust spinning around stars. To understand these cosmic mechanisms, researchers have typically used simulations to separately examine planetary development and magnetic field formation. Now, new work by researchers from the University of Zurich and the University of Cambridge has unified these fields of study in a single simulation for the first time ever.
Researchers knew that planets likely formed as a result of gravitational instabilities in the disks that allowed particles to congeal together, slowly forming planets over hundreds of thousands of years. With the new study, the research team aimed to examine the effects that magnetic fields have on planet formation in the context of those gravitational instabilities.
Ten Lessons The Coronavirus Has Taught Us About The Planet
In the four months it has taken for COVID-19 to scale beyond China's borders in mid January, much has been written that connects human health with our planet's health.

Several heroes have tried to stop this planet from rapid progression, but fail due to the ever-growing effects of the symbiotes.
This planet is home to the race of Korbinites which was one of the first planets to prompt superheroes and supervillains alike. Due to the mass population of highly advanced technology and mutations forming new-found heroes and villains, it became a target for the MCU and was attacked on various occasions.
The Great Divide: The Origin of Our Planetary Split – Now. Powered by Northrop Grumman
Our solar system resembles two very different planetary systems combined into one. These two groups of planets are separated by a disproportionately wide gap between Mars and Jupiter, dubbed “the Great Divide” by a study published in Nature Astronomy . Astronomers have been puzzled by this divide for decades.
* * *
According to The Planetary Society , a “snow line” between the inner and outer planets explains how the early solar system was divided into such different groups. Substances like water ice formed solid grains beyond the snow line, which eventually coalesced into the outer planets. Closer to the newborn sun, which shone brighter than today’s mature sun, the grains were vaporized and dispersed.
