Scientific Discoveries… On a Friday!
Hey guys! Apologies for this being a day late but I’ve been doing research on lemurs! But here is my round up of the week’s most interesting science news!
1.) Researchers are studying the growth of a new galaxy, 3 billion years after the big bang.
Researchers are now being able to track the development of the formation of a galaxy, in particular, of galaxy GOODS-N-774, or Sparky as it’s being affectionately called. It is an elliptical galaxy form, and is described as a ‘giant’. Because of it’s early stage of development, it’s creating around 300 stars a year, compared to around 10 a year from a developed galaxy. It was originally theorized that every galaxy starts off with a dense core, and develop from the inside out and thus expand. Sparky will hopefully allow scientists to test this theory and add more to how the big bang started off.

2.) A fossilised dinosaur nursery has been found.
This nursery contained at least 30 infant bones, and the bones of the ‘babysitter’ too! They were all members of a herbivore species, Psittacosaurus lujiatunensis. It poses a link between the babysitting behaviour of birds and dinosaur, cementing their evolutionary tracks.

3.) Mystery of the sailing stones has been solved.
The stones in Death Valley move across the surface of the dried up lake (a playa), seemingly by themselves. These rocks are so heavy, about 320kg! They are moved by a combination of wind and ice sheets melting into a small pool of water. So, the culprit is floating ice, who knew?!
What do you think guys? What’s been the most noteworthy science news you’ve seen so far this week? Let me know! And I hope you have a fab Friday!
