A Peculiar Polymer Paired with Sunlight Could Remove PFAS A new photocatalyst might help take the “forever” out of “forever chemicals” present in water.

Could sunlight, combined with a uniquely rigid and porous class of polymers, detect and remove PFAS from water supplies? 🧪

Don’t Blink: The Vera C. Rubin Observatory Is Revolutionizing Astronomy This April, Eos is focusing on the world’s newest observatory and all the fast and faint objects it’s allowing us to see.

This month, Eos is taking a quick survey of space and time. That’s right, we’re profiling the @vrubinobs.bsky.social and the fast and furious faint objects it’s allowing us to see.

Artemis II Lunar Targeting Plan - NASA Science A guide to the Artemis II Lunar Targeting Plan (the astronauts' Moon observing assignment).

The lunar observation period just began. Astronauts are taking images of lunar features, following their Lunar Targeting Plan that guides observations based on targets' visibility and value to science. science.nasa.gov/resource/art...

Just after breaking the distance record, in an emotional moment, the crew proposed names for two unnamed lunar craters: Integrity, after the name the crew chose for their spacecraft, and Carroll, in memory of the wife of #ArtemisII Commander Reid Wiseman.

The four astronauts of the #ArtemisII mission are now farther than any other humans have traveled from Earth, surpassing the Apollo 13 distance record set in 1970 😮. The crew will reach their furthest distance from Earth—252,760 miles—at approximately 7:07 p.m. EDT.

The official livestream covering the #ArtemisII flyby of the Moon has just begun! The four NASA astronauts on the Orion spacecraft are preparing for their observations of the lunar surface now. 👇

The exhibition drew visitors grappling in real time with personal impacts of wildfire.

Oceans Are Absorbing the Earth’s Excess Energy. That’s Bad News for Food Systems. As the planet traps more energy than it releases, the pathways for global food production are being upended.

Check out this story in @grist.org from @fridagarza.bsky.social: “Oceans, the World Meteorological Organization reports, absorb 91% of the excess energy hanging out in the Earth’s climate.” eos.org/articles/oce...

Before going to sleep on flight day 5, the Artemis II crew snapped one more photo of the Moon, as it drew close in the window of the Orion spacecraft. Orion and the four humans aboard entered the lunar sphere of influence at 06:37 CEST on 6 April, at the tail end of the fifth day of their mission. That marked the point at which the Moon's gravity had a stronger pull on the spacecraft than Earth's. Artemis II's closest approach to the Moon will come on flight day 6, as they swing around the far side before beginning their journey back to Earth.

✅ #Artemis II update: the spacecraft entered the lunar sphere of influence this morning at 05:37 BST/06:37 CEST, 6 April, at about 51 000 km from the Moon (the region of space where the Moon’s gravitational pull is stronger than that of Earth’s).

Titanic Shake-Up Could Explain Saturn’s Young Rings and Strange Moons A new model shows how the migration of Titan could have destroyed another moon, creating Saturn’s rings and the moon Hyperion. And, the model suggests, this all happened in the past billion years.

Young rings, weird moons, an oblique orbit…there’s a lot of strangeness surrounding Saturn and its moons. A new model suggests the expansion of Titan’s orbit could explain it all.

International Geologist’s Day began in the mid 60s in the former USSR and technically falls on the first Sunday of April.
There is even a "Geologist's Hymn"- a product of the times...

Small, Faint, or Fast, Rubin Will Find It The Vera C. Rubin Observatory is set to redraw the map of the solar system by discovering millions of small, fast-moving objects hidden all around us.

From asteroids and comets to interstellar objects and hints at Planet 9, @vrubinobs.bsky.social is going to rewrite solar system textbooks over the next 10 years and beyond.

'Not the moon that I'm used to seeing': Artemis II astronauts describe seeing the far side In an interview with NBC News from the Orion capsule, the crew described seeing the moon from a new angle, feelings of awe and humility, and their very human concerns in space.

Artemis astronauts have looked at the Moon from both sides now, from give and take, and still somehow …

Climate Science Has No Place in Scientific Reference Manual for Judges, Attorneys General Say - Eos A chapter on climate science has been removed from a manual designed to be an independent, neutral source of scientific information for judges.

“It's like we're at a time that somehow we think we have to give equal time to the people who believe that the Earth is flat,” says retired judge Nancy Gertner. “I mean, you don’t.”

As Ice Recedes and Land Rebounds, Antarctica’s Mineral Resources Come into Focus - Eos Melting ice, rebounding land, and rising seas will change what resources are available in Antarctica, a new analysis finds.

Climate change will melt Antarctica’s ice, causing land to rebound and revealing previously inaccessible deposits of valuable mineral resources.

FY2027 Budget Request Slashes Billions in Science Funding The Trump administration is requesting the cancellation of billions of dollars in funds for space science, renewable energy, carbon removal, and climate change education in its FY 2027 budget.

The Trump administration is requesting the cancellation of billions of dollars in funds for renewable energy, space science, and climate change education in its FY2027 budget. The cuts would help fund an increase in defense funding to a total of $1.5 trillion.
