Scientists publish the first complete human genome

Scientists released the first complete human genome on Thursday, filling gaps left after previous efforts while offering new promise in finding clues about disease-causing mutations and genetic variations among the world’s 7.9 billion people. . In 2003, researchers unveiled what was then claimed to be the complete sequence of the human genome. But about 8% of it hadn’t been fully deciphered, mostly because it consisted of highly repetitive pieces of DNA that were difficult to integrate with the rest.

NASA’s SOFIA Observatory studies neighboring galaxy Chile

An aircraft-borne telescope flew over Chile at night this month to observe part of the universe as scientists aim to better understand how stars are born. The US space agency NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), a state-of-the-art Boeing 747 equipped with a telescope capable of observing the entire infrared spectrum, arrived in Chile this month, marking his first visit to South America.

Hubble telescope spots Earendel, the most distant star ever recorded

Using NASA’s Hubble Space Telescope, scientists have discovered the most distant individual star on record, a bright giant they dubbed Earendel – Old English for “morning star” – because it existed at the dawn of the universe. The researchers said the very hot, blue-colored star was estimated to be 50 to 100 times the mass of our sun, while being millions of times brighter. Its light traveled for 12.9 billion years before reaching Earth, meaning the star existed when the universe was only 7% of its current age.
