NGC 2070 (30 Doradus, The Tarantula Nebula) in Dorado
In HaLRGB and Ha filters, and an annotated version.
The Tarantula Nebula (also known as 30 Doradus, or NGC 2070) is an H II region in the Large Magellanic Cloud (LMC).
The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 49 kpc (160 000 light years), this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows. In fact, it is the most active starburst region known in the Local Group of galaxies.
It is also the largest such region in the Local Group with an estimated diameter of 200 pc. The nebula resides on the leading edge of the LMC, where ram pressure stripping, and the compression of the interstellar medium likely resulting from this, is at a maximum.
At its core lies the compact star cluster R136 (approximate diameter 35 light years) that produces most of the energy that makes the nebula visible. The estimated mass of the cluster is 450 000 solar masses, suggesting it will likely become a globular cluster in the future.
Scientists Create 3D Model That Mimics Brain Function
"A doughnut created in a lab and made of silk on the outside and collagen gel where the jelly ought to be can mimic a basic function of brain tissue, scientists have found.Bioengineers produced a kind of rudimentary gray matter and white matter in a dish, along with rat neurons that signaled one another across the doughnut’s center. When the scientists dropped weights on the material to simulate traumatic injury, the neurons in the 3D brain model emitted chemical and electrical signals similar to those in the brains of injured animals.It is the first time scientists have been able to so closely imitate brain function in the laboratory, experts said.”
