John L. Young, who died March 28 at age 89 in New York City, was among the first people to see the need for an online library of official secrets, a place where the public could find out things that governments

Technology Readiness Levels (or TRL levels, because repeating the last word of initialisms is common in English) is a metric commonly used by NASA to define how developed a technology for use on a mission is. These typically range from 1-9, with 1 being an idea in someone's head, and 9 having been successfully flown on a mission. One of the assessments of new projects that NASA does is a check of the TRL levels of its constituent components - those with a higher level get higher marks, since it is assumed that the technology necessary to get them ready will require less work. So, sometimes, NASA and other organizations will sponsor smaller missions to work on a specific technology needed for one of its big flagship programs. That seems to be the approach from a team led by Keri Hoadley of the University of Florida, who recently laid out a mission concept for the Ultraviolet Type Ia Supernova CubeSat (UVIa).

For a while now, there has been a problematic mystery at the heart of the standard cosmological model. Although all observations support the expanding Universe model, observations of the early period of the cosmos give a lower rate of acceleration than more local observations. We call it the Hubble tension problem, and we have no idea how to solve it. Naturally, there have been several proposed ideas: what if general relativity is wrong; what if dark matter doesn't exist; what if the rate of time isn't uniform; heck, what if the entire Universe rotates. So, let's add a new idea to the pile: what if dark matter evolves?

Tracking the sources of photons is a hobby of many astrophysicists. Some types of photons are tied so closely to particular phenomena that tracking their sources would help answer some larger questions in astrophysics itself. Photons on the "511 keV line" are one such type of photon, and they have been overrepresented near the galactic core, with no known source being prolific enough to create them. A new paper from Zachary Metzler and Zorawar Wadiasingh of the University of Maryland and NASA's Goddard Space Flight Center suggests one potential source - millisecond pulsar (MSP) binaries.

If we could peel back the Moon's cratered crust and examine its mantle, we might find answers to some foundational questions that date back to the Apollo moon landings. We lack the technological capability to excavate the Moon's mantle, but Nature has a way. A massive, ancient impact excavated material from deep beneath the Moon's crust and left it on the surface for us to study. It could help confirm the Moon's origins.

NASA's Transiting Exoplanet Survey Satellite (TESS) has already uncovered hundreds of exoplanets of all sizes. Now, a team of astronomers is pushing the search even furtherthis time, looking for signs of planetary rings. Scanning 308 TESS planet candidates, they zeroed in on large, fast-orbiting worlds circling bright, nearby stars. Out of those, six showed subtle hints that rings might be present. But despite the tantalising clues, none offered definitive evidence of ring systemsat least not yet.

Youve probably heard that black holes stick around for a long timebut even they are not eternal. Over unimaginable spans of time, they slowly evaporate into space through a process called Hawking radiation. And heres the kicker: this doesnt just apply to black holes. Anything with massstars, moons, even youcan, in theory, evaporate in this way. Black holes are a special case since they dont have a surface and can actually swallow some of their own radiation, making their demise painfully slow. The biggest ones might take up to 10^100 years to disappear. But smaller objects? Something like the Moonor a human beingcould fade into nothingness in "just" 10^90 years.
