They observed the activity in May 2020, but it took a year to work out what they had seen. The planetary demise took place around 12,000 light-years away in the Aquila constellation, and involved a planet the size of Jupiter, researchers said. “It was unlike any stellar outburst I had seen in my life.”Īn artist's impression shows the planetary demise. “One night, I noticed a star that brightened by a factor of 100 over the course of a week, out of nowhere,” said De in a press release. Astronomers observed this as a white-hot flash, followed by a longer-lasting colder signal, which they later deduced was caused by the star engulfing a planet. The process sees a star billow out to a million times its original size as it runs out of fuel, engulfing any matter in its wake. “The fact that the solar system planets would get engulfed into the sun in the future was something I had read first in high school, so it was surreal to realize that we may have found the first ever example of catching a similar event in real time!” study lead author Kishalay De, a postdoctoral researcher at Massachusetts Institute of Technology, told CNN. While astronomers have previously seen planets just before and just after being engulfed by a star, this is the first time that a planetary demise has been observed, according to a team of scientists from the Massachusetts Institute of Technology, Harvard University and the California Institute of Technology. That’s contributed to the deaths of nearly 2,000 manatees in the past two years, representing more than 20% of all manatees in Florida, the groups said.Īn FWS spokesperson said the agency doesn’t comment on proposed or pending litigation.In a world first, scientists have observed the moment that a dying star consumed a planet - a fate that eventually awaits Earth. Since having their legal protections reduced in 2017 when the species was reclassified as threatened instead of endangered, manatee numbers have declined dramatically, conservationists said.įueled by wastewater treatment discharges, leaking septic systems and fertilizer runoff, algae blooms can become so thick that seagrass can’t get the sunlight it needs to survive, jeopardizing the manatees’ main food supply. Their closest living relative is the elephant. They also face peril from boat strikes and toxic red tide algae outbreaks along the state’s Gulf coast. Manatees are Florida’s official state marine mammal but are listed as a threatened species, with many dying from starvation due to pollution-fueled algae blooms killing the seagrass they rely on for food.



Manatees are gentle, round-tailed giants sometimes known as sea cows that weigh as much as 1,200 pounds (550 kilograms) and can live as long as 65 years.
