Astronomers Find Anomaly That Defies Understanding of the Universe
A new discovery in space may make us rethink everything we know about the universe.
Scientists at the University of Central Lancashire in the UK, have discovered a giant arc—an extremely large crescent structure of galaxies in distant space. Ph.D. candidate Alexia Lopez, who made the discovery, said, “It’s so big that it’s hard to explain with our current theories.”
The Cosmological Principle states that the universe is homogenous and isotropic, meaning the universe looks the same in all orientations. So how does the giant arc challenge our way of thinking about the universe?
Astronomer and Gaia News contributor Marc D’Antonio said, “this giant arc is really interesting because we’ve seen large-scale structures before in the universe, but nothing of this size. The proportion of this is something that’s actually outside our understanding of current cosmology.”
“What’s interesting about that is, this particular arc, it’s about 9.2 billion light-years away from us, and it’s about 3.4 billion light-years in size. Now keep in mind, that’s a good fraction of the size of the known universe, which is somewhere in the order of 91 or 92 billion light-years in diameter.”

NASA Announces Plans to Colonize the Moon By 2030
NASA has committed to putting humans on the moon by 2024 and human settlements by 2030, but what will it take to achieve this lofty goal?
Under NASA’s Artemis program the space agency announced the priority of going back to the moon with settlements on the lunar surface by 2030 that would act as a launch point for future missions to Mars. The program has many goals, chief among them to learn how to live on the surface of another planet.
But the moon’s surface is a harsh and hostile environment. Micrometeorites pelting the surface like missiles, 400-degree temperature swings, and the constant risk of radiation exposure from the sun create many obstacles for putting long-term settlements on the lunar surface. On the moon, we will have to supply the same foundations of human survival as we do on Earth including water, shelter, food, and oxygen. NASA is partnering with public and private partners to solve these problems.
So how will astronauts access these vital resources needed for survival? NASA won’t be able to bring sufficient life-sustaining resources from Earth, so they’ll have to make it upon arrival.
