Sometime between now and September, if you look to the left-hand side of the Northern Crown, what will look like a new star will shine for five days or so."

At the end of last year, a staggering 36,500 space debris objects over 10 cm in length were orbiting the Earth — perhaps little shock to anyone familiar with the Kessler Syndrome, a concerning theory that the more space junk there is, the more collisions there will be, causing a self-perpetuating chain reaction that could result in Earth’s orbit becoming essentially unusable..."

"It’s difficult to say exactly how many asteroids will be lost… but preliminary results suggest that for every five near-Earth asteroids we discover, we lose one solely due to constellation interference. That’s if no mitigation measures are taken”
