Astronomers scouring the cosmos for new planets have made a chance discovery, identifying the rare eclipse of two brown dwarfs .
"This is a great example of scientific serendipity," Adam Burgasser, a co-leading author on this study and a professor of physics at UC San Diego, said in a statement . "While searching for planets, we found an eclipsing brown dwarf binary, a system that is uniquely suited for studying the fundamental physics of these faint celestial objects."

Three teams of astronomers have been fascinated by an alien world known as K2-18b. But what's all the fuss about?
"We recognized pretty early on that this is a very unique target," Björn Benneke, an astronomer at the University of Montreal, told Space.com. Benneke led one of the teams that announced the atmospheric analysis in the September 2019 study, which was published in The Astrophysical Journal Letters in December. He presented the findings in January at a meeting of the American Astronomical Society.
Why Didn't Saturn Eat Titan, Its Biggest Moon? - The New York Times
In classical mythology, the titan Cronus, who was reinterpreted by the Romans as Saturn, devoured his newborn children to prevent a prophesied coup. (He did not succeed, and Zeus became the king of the gods.)
In planetary science, a similar scenario emerges when scientists recreate the evolution of large planets like Saturn, which has a satellite system dominated by one massive moon, Titan. Typically those simulated planets either eat their orbital retinue, or multiple sizable moons survive into adulthood, like the four Galilean moons of Jupiter.

Fragment of Planet That Hit Earth May Be Buried Inside Moon
Where did the Moon come from and how was it formed? It's a question that scientists have been scratching their heads over for decades.
According to the widely-accepted " giant-impact hypothesis ," the Moon was formed billions of years ago when a Mars-sized planet called Theia collided with the Earth, breaking off a large chunk in the process.
Now, researchers from the University of New Mexico say in a new paper published in Nature Geoscience that they believe they've found the remains of Theia buried beneath the lunar surface.
Look Up! Supermoon, planets to dazzle Monday's sky

ORLANDO, Fla.- – March's full "worm" moon will be a supermoon, meaning the moon is full while also in perigee, or closest approach to Earth. Monday's supermoon will appear to be the second-biggest full moon of the year. April's supermoon will appear slightly bigger in the night sky. The March full moon is referred to as the worm moon because the ground begins to thaw and earthworms soon reappear for spring.

Early risers Monday will be in for a bonus treat. Before sunrise, opposite of the supermoon in the western sky, will reside four planets in the east. Jupiter will be the brightest and will be in close proximity with Mars and Saturn. Mercury will be by itself and closer to the horizon.
‘Baby giant planet’ discovered just 330 light-years from Earth
It might not be the same as finding Baby Yoda or “Baby Shark,” but scientists have discovered a “baby giant planet” just 330 light-years from Earth.
Known as 2MASS 1155-7919 b, the exoplanet has a mass just 10 times the size of Jupiter, the largest planet in the Solar System. It orbits a star that is 5 million years old at 600 times the distance the Earth orbits the Sun, researchers said in a study published in the journal Research Notes of the American Astronomical Society.

The concept of mottainai encompasses the idea of respecting resources and not wasting them, along with an inherent recognition of their value.
Reaching across the counter to pass us a beautifully wrapped pack of homemade senbei (rice crackers), the elderly shopkeeper joined in our admiration of the colourful designs. Each pack was nestled in traditional washi paper, which, the shopkeeper suggested, could be used again for gifts or to cover a notebook. “ Mottainai ,” she called as we left, wagging a finger with the perfect stern-grandmother tone to match.
