Betelgeuse, the red giant, the 10th brightest star in the night sky and one of the easiest to see with the naked eye, is about 20 times the size of the Sun. If you’re looking at the constellation Orion, the massive orange star is the right armpit.
But in the last few years, the star had been dimming. Scientists couldn’t figure out why exactly. There were theories that massive clouds of dust were blocking its light. Other theories were literally explosive. Was the star going to go supernova and explode as the gravity pushing in on the star collided with the heat pushing out?
A new study published this week in the journal Nature explains what was happening to this star that humans have been gazing upon for as long as there have been humans. It’s our lead story today. Keep scrolling to read more.

Mailbag — Keep sending your stories about national parks. This month the administration of President Joe Biden announced it would restore protections to the Tongass National Forest in Alaska to keep its trees shielded from loggers and road construction. (The protections were stripped away during the administration of Biden’s predecessor.) With that news in mind, and with vacation season upon us, what is your favorite national park and why? It can be in the United States or elsewhere. Send your answer to firstname.lastname@example.org, or if you’re reading this in your inbox, just reply to this email.
Here are two of my favorites:
Sharing beers and just being super chill — “Kruger National Park in South Africa itself is not only one of the oldest parks in the world but is also pretty big (around the size of New Jersey). The wildlife is wonderful and there’s a real camaraderie between visitors; telling each other where good sightings are, sharing beers, and just being super chill. Mana Pools in Zimbabwe is very, very wild. The sort of place where you pitch a tent wherever you are and know you won’t see another human. Try not to stare into the night, as you’ll often see the eyes of animals staring back at you. (PSA: Hyenas are much bigger in person.) — Dovi in South Africa
Makes you feel so alive — “I live in a small coastal town in Oregon with the most natural beauty in the U.S. The true National Park in Oregon is Crater Lake! Magnificent! I have visited in the fall before the snow hits and in May when there were walls of snow about 15 feet high. Both times it was amazing although a bit more fun in the summer/fall. Love the views and the trails! Also, I have to admit that I truly enjoyed listening to the park rangers describing the flora and fauna of Crater Lake. They could really capture the essence and make you feel so alive from the beginning of how the Lake was formed until the present day. I can't wait to go again to learn more!” — Kate in Oregon
So when claims that Betelgeuse was on the verge of an explosive death began circulating in late 2019, Montargès, a researcher at the Paris Observatory, was not ready to let his star go.
“I would have to spend a decade of my life with Orion’s empty shoulder,” Montargès tells Inverse. “I'm not ready to go through that.”
Thankfully, he didn’t have to.

SpaceX will launch a critical Space Force satellite on a previously used rocket later this week for the first time, which could cement SpaceX’s reusable rockets as safe for the Space Force’s operations.
SpaceX has already launched three Space Force satellites into orbit on fresh rockets. The first launch with a reused rocket is planned for Thursday, June 17, with the launch of the GPS III SV05 satellite.
This satellite is the final piece of hardware the Space Force needs in orbit to complete its network of M-Code satellites, which are purported to be more resistant to jamming and cyberattacks.

Stories of police officers being hospitalized or even overdosing on fentanyl, simply by touching the powerful opioid, are regularly reported. These events are echoed in the training materials given to officers. In 2016, for example, the Drug Enforcement Agency released a video for law enforcement warning that simply touching fentanyl could be fatal, adding, “exposure to an amount equivalent to a few grains of sand can kill you.”
There’s just one problem: It’s not true.
