NASA unveils dazzling new images of the ‘Cat’s Eye Nebula’ The space-based telescopes Hubble and Euclid combined forces to capture a dying star in stunning new detail

The space-based telescopes Hubble and Euclid combined forces to capture a dying star in stunning new detail

I want to repeat comments I already made on this plot since some news outlets seem to ignore them: Hubble will not reenter until early 2030s. The curve here is alarming, but will flatten out as we hit solar minimum in the coming years. I still think it's time for NASA to take action on a reboost.

It is a truth universally acknowledged that babies love bubbles 🔭🧪

The attempted polarity reversal and evolving magnetic environment of AD Leo In the past two decades, the observed large-scale magnetic field of the active M dwarf star AD Leo has evolved from strongly to mildly negative, raising a suspicion that it might switch polarity. Alth...

Pope Leo Will Spend July 4 Visiting Migrant Crossing Island Pope Leo has spoken out against the treatment of migrants in the United States several times over the last year.

JD Vance personally invited Pope Leo to the U.S. 250th celebration on the 4th of July. Today the Vatican announced Leo will be spending the day with migrants instead.

as far as i can tell “bio hacking” is just a goofy term for giving yourself some combination of an eating disorder and a drug addiction

What I Saw at a Maternity Ward in Kenya After the U.S. Cut Off Food and Foreign Aid Photographs tell a story of two mothers determined to help their babies gain enough weight to leave the hospital — only to face little to no food again.

A maternity ward doctor donated his own blood during surgery to keep a pregnant patient alive.

One woman gained fewer than 10 pounds over her entire pregnancy.

Another collapsed and had seizures during labor.

‘He’s not the same’: Father of Liam Conejo Ramos says 5-year-old continues to suffer Some people thought they say the 5-year-old during the Super Bowl halftime show. But Liam is still in hiding with his family, after he and his father were detained and then released from a Texas deten...

Super Bowl viewers Sunday speculated that 5-year-old Liam Conejo Ramos appeared in the halftime show. In fact, he has been in hiding with his family.

“He can’t sleep well at night. He wakes up three or four times a night screaming, ‘Daddy, Daddy,’” Liam's father Adrian Conejo Arias, said.

Renee Good's partner addresses Minneapolis immigration crackdown one month after killing Becca Good has seldom spoken out since Renee Good was shot and killed by an ICE agent in Minneapolis on Jan. 7.

“Renee was not the first person killed, and she was not the last,” Becca Good said. “You know my wife’s name and you know Alex’s name, but there are many others in this city being harmed that you don’t know — their families are hurting just like mine, even if they don’t look like mine.”

Inside TurboTax’s 20-Year Fight to Stop Americans From Filing Their Taxes for Free Using lobbying, the revolving door and “dark pattern” customer tricks, Intuit fended off the government’s attempts to make tax filing free and easy, and created its multi-billion-dollar franchise.

With tax season in full swing, here's our reminder that TurboTax owner Intuit spent two decades fighting to prevent Americans from filing their taxes online for free.

The Clear Labels Act Would Change What You Know About Your Prescription Medication The bill, introduced by Sens. Rick Scott and Kirsten Gillibrand, follows a bipartisan investigation that cited ProPublica’s reporting on dangerous foreign drugmakers and the medicine they continued…

NEW: The FDA won’t tell Americans where their generic drugs are made, so ProPublica built the Rx Inspector tool to show you.

Now a proposed bill would also require manufacturing location information on packaging for both generic and brand-name drugs.

It's just over a year since we joined @bsky.app. Check out our updated #StarterPack and see what's changed!
