Her birth represents the first cloning of an endangered species native to North America, and may bring needed genetic diversity to the species. From a report: Last year, Ben Novak drove across the country to spend New Year’s Eve with a black-footed ferret. Elizabeth Ann had just turned 21 days old — surely a milestone for any ferret but a particularly…

Megalodon shark’s enormous babies ate their siblings in the womb
Megalodons – the extinct giant sharks that lived in most of Earth’s oceans about 3 million years ago – gave birth to babies that were larger than adult humans, scientists say. Source: https://earthsky.org/earth/megalodon-extinct-giant-shark-enormous-babies…
Newborn megalodons were larger than a human
The world’s largest shark was over two meters long at birth thanks to its penchant for eating its siblings. Measuring up to 60ft in length, this prehi… Source: https://www.unexplained-mysteries.com/news/342886/newborn-megalodons-were-larger-than-a-human…

Dark storm on Neptune changes direction, escapes deadly fate
Astronomers used the Hubble Space Telescope to observe unusual weather on the planet Neptune, not observed until now. They saw a large, dark storm on Neptune unexpectedly changing direction, thereby saving itself from looming destruction and possibly producing a smaller companion storm.

Dark energy camera snaps deepest photo yet of galactic siblings
Images from the Survey of the MAgellanic Stellar History (SMASH) reveal a striking family portrait of our galactic neighbors—the Large and Small Magellanic Clouds. The images represent a portion of the second data release from the deepest, most extensive survey of the Magellanic Clouds. The observations consist of roughly 4 billion measurements of 360 million objects. Source: https://phys.org/news/2020-12-dark-energy-camera-snaps-deepest.html…
Star clusters are only the tip of the iceberg
“Clusters form big families of stars that can stay together for large parts of their lifetime. Today, we know of roughly a few thousand star clusters in the Milky Way, but we only recognize them because of their prominent appearance as rich and tight groups of stars. Given enough time, stars tend to leave their cradle and find themselves surrounded by…
Citizen scientists spot closest young brown dwarf disk yet
Brown dwarfs are the middle child of astronomy, too big to be a planet yet not big enough to be a star. Like their stellar siblings, these objects form from the gravitational collapse of gas and dust. But rather than condensing into a star’s fiery hot nuclear core, brown dwarfs find a more zen-like equilibrium, somehow reaching a stable, milder state…
