Hello, Moon. It’s great to be back.
Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-multimed…

I'm honestly SHOCKED at how the general public has NO IDEA Artemis II is taking humans out to the moon and will be the furthest humans have ever flown. Every non-space nerd I've talked to has no idea. WE GOTTA GET PEOPLE STOKED!!!! THESE FOUR HUMANS ARE FLYING TO THE MOON!!!

Using Georgia State's Center for High Angular Resolution Astronomy (CHARA) , astronomers have captured images of two stellar explosions in unprecedented detail. Their findings were recently published in the journal Nature Astronomy.

Ivy League schools rediscover, sometimes as if for the first time, that standardized tests predict success in college:
1. Dartmouth (Feb 5, 2024):
“Several key findings guided our decision: First, standardized test scores are an important predictor of a student's success in Dartmouth's curriculum, and this is true regardless of a student's background or family income.”
“Research shows that standardized test scores can be an important predictor of academic success at a place like Dartmouth and beyond—more so even than just grades or recommendations, for example.”
2. Yale (Feb 22, 2024):
“Yale’s research from before and after the pandemic has consistently demonstrated that, among all application components, test scores are the single greatest predictor of a student’s future Yale grades. This is true even after controlling for family income and other demographic variables, and it is true for subject-based exams such as AP and IB, in addition to the ACT and SAT.”
3. Brown (March 5, 2024):
“Our analysis made clear that SAT and ACT scores are among the key indicators that help predict a student’s ability to succeed and thrive in Brown’s demanding academic environment.”
4. Harvard (April 11, 2024):
“Research by Opportunity Insights has shown that SAT and ACT scores are the single strongest predictors of academic success at selective colleges like Harvard... Standardized tests provide a common benchmark that can help us evaluate applicants’ readiness for the academic challenges at Harvard in a way that is more fair and equitable than high school grades alone.”
5. Cornell (April 22, 2024):
“After a multi-year study conducted by the university’s Task Force on Standardized Testing in Admissions, data showed that when reviewed in context with other application materials—such as GPA, academic rigor, extracurricular engagement, essays, and letters of recommendation—test scores help to create a more complete picture of an individual applicant.”
6. Penn (Feb 14, 2025):
“Penn’s practice has been, and continues to be, considering a student’s school-based academic record on its own merit, with testing as part of Admission’s broad and comprehensive assessment. With this approach, testing complements a student’s existing accomplishments and can offer additional relevant information in our comprehensive and holistic admission process.”
7. Princeton (Oct 9, 2025):
“The decision to resume testing requirements follows a review of five years of data from the test-optional period, which found that academic performance at Princeton was stronger for students who chose to submit test scores than for students who did not.”

View of Starship landing burn and splashdown on Flight 10, made possible by SpaceX’s recovery team. Starship made it through reentry with intentionally missing tiles, completed maneuvers to intentionally stress its flaps, had visible damage to its aft skirt and flaps, and still executed a flip and landing burn that placed it approximately 3 meters from its targeted splashdown point

Meet Gaia18cdj, the truly biggest boom since the Big Bang. Record holder of the new sample of Extreme Nuclear Transient events. Two of these events were found through @gaia_alerts, Gaia's Photometric Science Alerts. cosmos.esa.int/en/web/gaia/i…

New class of transient events found thanks to Gaia and ZTF: Extreme Nuclear Transients or ENTs! These events are the most energetic explosions in the universe known. They are powered by massive stars being torn apart by supermassive black holes. More details: cosmos.esa.int/en/web/gaia/i… GIF credits: based on artwork from the University of Hawaii, Nancy Hulbirt.

It's rare for a grad student paper to spark a new subfield—but this collab between @UHIfA’s Colby Haggerty and the Shappee transient group might do just that, solving key mysteries in supernovae & kilonovae! Check it out!

In it, Dhvanil Desai @dhvanil12299 shows that relativistic electrons and positrons from radioactive decay stay trapped in the ejecta far longer than expected. Hoisted by their own petard, they generate magnetic fields that confine them and facilitate the transfer of decay energy to ions, ultimately responsible for the luminosity we observe.

Eye to the sky…on-sky engineering tests have begun at @NSF–@doescience Rubin Observatory with the world’s largest camera!
After installing & testing the LSST Camera, we turned the telescope to the sky—a moment 20 years in the making!
Rubin #CommissioningNotes are back! ✍️

These findings are from a study in @ScienceAdvances which had 120 adults from 16 countries undergo 3 days of online training to suppress either fearful or neutral thoughts. science.org/doi/10.1126/scia… 2/9
