Recently an element found in human teeth was detected for the 1st time in a galaxy 12 billion light-years away. This indicates that stars exploded and realized critical elements from their core into space during the early chaotic days of the universe. Then those elements reached Earth and inside the human bodies. Space may seem alien, dark, cold, but it’s not as far removed from humans as humans think.
Recently, the astronauts hosted a taco party to celebrate and snack on the 1st chilies peppers grown in space on the ISS. The researchers are trying to find out if the exoplanet TRAPPIST -1 system which contains seven planets the size of the Earth. It is time to find out about other planets like Earth and find out whether Earth is alone in the universe. This is the long-awaited Astro2020 ten survey consensus released last week. This will serve as a roadmap for NASA to plan missions.
Over the following decades, scientists will try to find out the universe’s secrets and identify Earth-like planets outside of our solar system to find other habitable worlds. Across the galaxy, there are over 4000 known exoplanets. But more information is needed by astronomers to find actual signs of habitability and life.
A large telescope will help in this mission which is expected to launch in 2040. It will try to find out life signs on about 25 potentially habitable exoplanets. On Earth, all eyes are on the COP26 climate summit in Scotland as the world leaders try to reduce climate change. The gap between the impacts of climate change and the human’s effort to adopt them is increasing. At the summit, 20 countries agreed to end financing for fossil fuel projects abroad in a deal. Curtailing fossil fuels could limit long-term global warming. One way to cut back on emissions is to convert classic cars into electric vehicles.
Meet Leti lived between 236,000 and 335,000 years ago, is the minor child of an ancient human relative. At the time of death, the skull from a child that was 4 to 6 years old is the 1st known to belong to Homo Naledi. In South Africa’s Rising Star cave, the fragments of the child’s skull were found in an incredibly narrow passage. This is the place where Homo Naledi fossils were initially unearthed in 2013. The discovery of a child fossil can indicate to the researchers how this enigmatic species developed.
In South America, intense heat turned the Atacama Desert’s sandy soil into vast areas of glass stretching for 46.6 miles about 12,000 years ago. For many years researchers have tried to find out what caused this drastic change. Scientists have found minerals with an extraterrestrial source within the dark green and black glass fragments scattered across the Chilean desert. Baby seals know how to get attention because they share a rare vocal ability with humans. This adjustment, known as being vocally plastic. Scientists in the Netherlands studied wild-born seal pups between 1 and 3 weeks old at rehab and research center. The scientists recorded how the seal pups responded to recordings of sea noise.
