European and U.S. scientists reported that the green aurora in the dusty Martian sky was generated by alast year and had three days’ advance notice to set aside viewing time with thePrevious auroras observed at Mars appeared only in the ultraviolet, but this one was in the visible wavelength. It resulted from a solar flare in March 2024 that was followed by a coronal mass ejection of plasma from the sun that was directed toward Mars.

These latest observations show that forecasting of northern and southern lights is now possible at Mars, allowing scientists to study space weather, said University of Oslo’s Elise Wright Knutsen , whose research appeared Wednesday in the journal Science Advances.“While the brightness of this event was dimmed by dust, events under better viewing conditions or more intense particle precipitation might be above the threshold for human vision and visible to future astronauts,” the researchers wrote.

This was the first time an aurora had been reported from the surface of a planet other than Earth, the researchers noted. Earlier observations were made from orbit.

Launched in 2020, Perseverance has been exploring Mars’ Jezero Crater since 2021, collecting dust and rock samples for eventual return to Earth. The region, now dry but once believed to be a flowing lake and river delta, could hold evidence of ancient microbial life.“I was trying to make him healthier and make him live longer,” Journell said.

Instead, Alexander died on Thanksgiving Day. Tuxsie followed two days later.Big Boy was hospitalized and treated with antiviral medications, Journell said. The veterinary team collected urine samples from the cat, which were confirmed positive for H5N1 at labs run by the U.S. Agriculture Department and Cornell University, records show.

Big Boy returned home blind and without the use of his back legs, though he is recovering, Journell said. A fourth cat, Cleo, didn’t drink the milk and remained healthy.Journell has demanded that Raw Farm owner Mark McAfee compensate him for the more than $12,000 he spent treating the cats, according Seattle food safety lawyer Ilana Korchia, who is representing him.
