How the first photo of a Black Hole was captured


(CNN) — This week, scientists shared the very first photo of a supermassive black hole, and the much-anticipated final results of NASA’s Twins Study researching longterm spaceflight’s effect on the human body were released.


Spending 340 days aboard the International Space Station between 2015 and 2016 caused changes in astronaut Scott Kelly’s body, from his weight down to his genes, according to the results of the NASA Twins Study, released Thursday.


Together, 13 bones found in Callao Cave in the Philippines represent our only knowledge of a newly discovered species related to humans called Homo luzonensis.


No DNA was extracted from the hand and foot bones or teeth, but the fossils contain an intriguing mix of archaic and progressive traits that can be traced to Homo sapiens as well as Australopithecus afarensis.


There’s been a lot of scientific excitement in recent years about rocky Earth-like planets orbiting small red dwarf stars close to our solar system.


“Given that the early Earth was inhabited,” the researchers wrote, “we show that UV radiation should not be a limiting factor for the habitability of planets orbiting [small red dwarf]stars.
