Small cat attempts to catch Artemis II on tv

They will be caught…

I think the persistent white dot in the last image is the moon….

This is figure 1 from “Broadly stable atmospheric CO2 and CH4 levels over the past 3 million years.” It shows characteristics of the greenhouse gas data from the ALHIC1901 ice core.

Key climate shifts in the past 3 million years may have been more heavily influenced by changing ocean temperatures than greenhouse gases, according to analyses of ancient Antarctic ice cores published in two Nature papers.

NASA’s Europa Clipper Radar Instrument Proves Itself at Mars - NASA The agency’s largest interplanetary probe tested its radar during a Mars flyby. The results include a detailed image and bode well for the mission at

First light for the REASON radar on Europa Clipper, taken from Mars, the first stop on our way to the Jupiter system in 2030! No subsurface echoes were expected in this part of the red planet, but some great measurements of the surface of Mars. More coming at #AGU25! www.nasa.gov/missions/eur... 🧪🚀🪐

Will anyone review this paper? Screening, sorting, and the feedback cycles that imperil peer review Scholarly publishing relies on peer review to identify the best science. Yet finding willing and qualified reviewers to evaluate manuscripts has become an increasingly challenging task, possibly even ...

1. Kevin Gross and I just posted a new science-of-science preprint.

This one explores the looming peer review crisis. As many of you know, it's becoming significantly more difficult for journal editors to find scholars willing to serve as peer reviewers for submitted manuscripts.

This is awesome. This Mars lander version of Voyager would die, being coupled to Saturn as a launch vehicle, before being reincarnated as Viking (great history here www.nasa.gov/wp-content/u...). These notebooks probably have the full evolution! Echoes of Europa Clipper's story.

A map showing the topography of Antarctica, without ice

We’ve just published the most detailed map yet of the landscape beneath Antarctica’s ice sheet (called Bedmap3), and we learnt some pretty cool facts about Antarctica that you can use to impress your pals. Ready?

And here is the view from the Moon!

Firefly Aerospace’s Blue Ghost lunar lander took this image of the eclipse around 3:30 am CDT on March 14 from the Moon’s Mare Crisium. It shows the Sun about to emerge from totality behind Earth.

Pattern of CO2 over the past 66 Million years. The curve begins around 720ppm, peaks at 1600ppm 51 Million years ago and then declines toward today when a marked increase in CO2 is observed that is caused by human CO2 emissions.

For the first time ever, recorded atmospheric CO₂ has exceeded 430ppm! The last time CO₂ consistently reached today’s human-driven levels was ∼14 Million years ago, with shorter periods of similar levels around 3-5 Million years ago.

Looks like the DC sites have been pulled from the list?

DOGE’s Chaos Reaches Antarctica Daily life at US-run Antarctic stations has already been disrupted. Scientists worry that the long-term impacts could upend not only important research but the continent’s delicate geopolitics.

I think having reviews in hand will help whoever has to pick up the pieces in a hurry. And given the dubious legality of these firings, I wouldn’t be surprised if the piece picker uppers ended up being the people who got fired…

N.S.F. Cuts Raise Fears of a Reduced U.S. Presence in Polar Regions (Gift Article) The National Science Foundation has fired workers at the office that manages polar research, raising fears about a reduced U.S. presence in two strategic regions.

The Antarctic part of the NSF/Office of Polar Programs was particularly exposed to the recent firings, due to a bunch of turnover during the last few years - ironically they were recovering from that by converting temporary rotators from academia to permanent staff.

Upon learning that yesterday would be my last day as a program officer at the National Science Foundation, I shared this parting message with my colleagues. The next few months will be frenetic and stressful for them. Here are some things that you can do to help them with the mission ahead. (1)

Apparently New Zealand has a new, somewhat misconceived, tourism logo. New Zealanders are making the most of it.

1. Today the NIH director issued a new directive slashing overhead rates to 15%.

I want to provide some context on what that means and why it matters.

A Primer on Indirect Cost Rates

1/ Here's my take on what's happening with DOGE.

I've got fed experience through contracting with Health & Human Safety, Head Start, The Centers for Medicare and Medicaid Services, and DOD. I get brought in when people need to get shit done. Other people here have way more experience than me.

Bluetorial-A dream and a bit of a nightmare

Serving as Editor-in-Chief at Science was fascinating. I greatly enjoyed working with talented and committed editorial, news, graphics, and production staff. But the inside look into scientific publishing and AAAS was also deeply disillusioning.

An infrared light echo traveling from the lower left through the upper right of the image. The image is speckled with dozens of white stars, some showing Webb’s signature 8-point diffraction spikes, against the black background of space. The image also shows tightly packed, glowing red filaments that resemble muscle fibers or wood grain.⁣ Credit: NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC)⁣

genuinely this just became one of my favorite jwst images ever. it looks like a cosmic painting!!!

what a GREAT way to start 2025.
