Okay, The Title Of The Atlantic’s Article Might Be A Little Click-bait-y. But The Discovery Is Truly

Can you tell us something about j1407b?

J1407b is an exoplanet (but it can also be a brown dwarf) very interesting, orbiting its star J1407. It is larger than Saturn or Jupiter, and is surrounded by a ring system that is about 200 times larger than the rings of Saturn, very different from what we are accustomed to see.

Thirty-seven rings extending 90 million kilometers from the planet — over half the distance from the Earth to the sun — encircle the world. These planetary rings are the first found outside the solar system.

This exoplanet is 434 light-years away in the constellation Centaurus.

J1407b could house moons that could be formed by the material of the rings. One of their moons could be as large as Mars or Earth, and could orbit between the gaps of the rings, shaping them.

Astronomers expect the rings to become thinner in the next million years and eventually disappear as they form satellites from the material of the rings.

The discovery of the J1407 system and its unusual eclipses were reported by the team led by astronomer Eric Mamajek of the University of Rochester in 2012. The orbital period of J1407b is estimated at about a decade.

Simulation of the eclipse of the star J1407 by the ring system around its putative exoplanet J1407b. Each time a ring passed in front of the star, it dimmed. When entering a gap, the star brightened up again. Graphing the highs and lows, scientists created a profile of the ring system.

What the rings of J1407b would look like in our sky (above the Old Observatory in Leiden, Netherlands) if it was located where Saturn is now.

Hiking to the largest Ammonite in the world!

Video description:

Titanites lived during the Late Jurassic Period and had a shell diameter of around 137 centimetres! surprisingly it wasn’t the largest ammonoid, as some species such as Parapuzosia could get over twice as large!

There were also some plant fossils around the area of this site!

In honor of the first frost of the year, I propose a new winter cryptid: the Snow Crow.

Who sparks those ice crystals along rooftops and cars?  If they’re in a good spot for sledding, it might just be a Snow Crow.

RECORD BREAKERS

Life on earth, as magnificent and versatile as it is, is seemingly tame compared to the weird and wonderful creatures that once existed. All categories of life have reached unimaginable sizes, here are just a selection of prehistoric record breakers!

MEGALODON The biggest shark known to have existed, ruling over the oceans as recently as up to a million years ago. A length of almost 20 metres and weighing in at an estimated 48 tonnes, Megalodon could deliver a crucifying bite of up to 110,000N. It is no surprise that the Megalodon was dubbed the “whale killing shark”.

MEGATHERIUM Our early ancestors would have been quite familiar with Megatherium as they existed up to 8000 years ago, they were in fact the largest sloths to have existed. Sloths have a reputation as being lazy, slow and docile, but Megatherium was a 6 metre long, 4 tonne monster with a killer instinct and knife-like claws. Megatherium’s discovery came before that of the dinosaurs. Skeletons of these prehistoric beasts were a delight to the Victorian public and paved the way for the science of palaeontology.

ARCHELON Literally meaning “large turtle”, Archelon certainly was just that. Existing during the cretaceous, the time of the dinosaurs, Archelon could reach 4.5 metres long and may have lived to over 100 years old. Archelon could not compete with other cretaceous beings in speed and agility, but its blade-like beak was able to slice through flesh and crush though the toughest ammonite shells. Unfortunately Archelon appears to have been a popular snack for other marine dwellers, skeletons are frequently missing flippers or heads and covered in slashes.

TITANOBOA When the dinosaurs reign ended, a new era saw the rise of new super-predators, one was Titanoboa, the largest snake ever with a body up to 13 metres long, standing a metre off the ground and weighing up to 2500 pounds. Titanoboa was 30% longer than even todays largest species. Scientists believe this humongous snake hunted like its modern relatives, the boa constrictors, by winding around prey and suffocating them.

IRISH ELK Owner of the largest antlers of any animal, up to 3 metres wide, the Irish Elk gets its name from its frequent discoveries in Irish peat bogs. Existing up to 10,000 years ago, these would have been a common sight in grasslands for our ancestors. Many fossils indicate the animals died of starvation which is why the antlers are thought to have been part of elaborate mating contests between males, often resulting in one being fatally injured and unable to feed itself.

DEINOTHERIUM A distant relative of the elephants and mammoths, Deinotherium was more sinister, its name translates to “terrible beast”, they would have most likely caused trouble for our ancient ancestors around 1.5 million years ago. Deinotherium is actually considered to be the second largest land mammal of all time, behind Paraceratherium and is iconic in appearance due to its sharp, downward facing tusks.

ARCTODUS Known as the short faced bear, they were the biggest bears on record and one of the largest mammal carnivores to have existed. Whilst their skull was short, they were packed with piercing teeth that could deliver a bone crushing bite. Existing up to 11,000 years ago, out ancestors would have stayed well clear of this 900 kilogram predator, with slender limbs and knife-like claws, Arctodus was deadly.

SARCOSUCHUS One of the most infamous fossil discoveries in history, Sarcosuchus was the largest crocodile to walk the Earth up to 112 million years ago, this was a crocodile capable of killing dinosaurs. Sarcosuchus was twice as long as a saltwater crocodile, that’s 11-12 metres long and could reach over 8 tonnes. Its jaw was packed full of 66 teeth either side of its jaw and would have clamped down on prey that wandered too near.

ARGENTINOSAURUS One of the largest lifeforms that has ever stood on the Earth, Argentinosaurus could grow up to 30 metres long with its hind limbs standing 4.5 metres off the ground. They existed between 97-94 million years ago and at adulthood would have been virtually indestructible to predators. Its weight is estimated at a staggering 80-100 tonnes. There hasn’t been another land mammal on the same scale as Argentinosaurus since and it’s unlikely there ever will be.

SPINOSAURUS The largest discovered therapod ever, a group that includes Allosaurus and Tryrannosaurus. Spinosaurus remained an enigma to scientists for decades, the only discovered specimen was sadly destroyed during World War 2 and was not rediscovered until the 21st century. Spinosaurus is thought to have reached up to 16 metres long and weighed in around 12 tonnes, that is almost double the weight of a T-rex!

Jupiter and Moons, January 24, 2014 by Hubble Heritage

I found a really cool Youtube channel called History of the Earth that covers topics in the incredibly distant past. I'm talking billions of years ago. And learning how the Earth itself formed and where water came from and about the very first single-celled organisms is just like... woah. WOAH.

It's wild that billions of years ago there were just some bacteria hanging out in the ocean and now we have all this. It's really humbling and puts into perspective how precious our planet is. How precious life is.

Important science info guys.

Dunkleosteus, motherfuckers.
