Happy Asteroid Day! Prize-Winning Plan Focuses on Space Infrastructure

A proposal to create a new network for monitoring cosmic threats to off-world infrastructure has won this year's Schweickart Prize, which recognizes bright ideas for planetary defense.



A Quasar at Cosmic Dawn Flickers into View

Astronomers have detected a flickering quasar called J0439+1634 as it appeared only 850 million years after the Big Bang. That discovery raises fresh questions about black hole formation and activity in the early Universe. The flickering light of this distant cosmic lighthouse showed that black hole at the heart of the quasr has a flat, pancake-shaped accretion disk. That shape is more familiar in modern-day quasars, which leads astronomers to wonder how these objects formed so quickly in the infant cosmos?



Another Early Universe Surprise from the JWST: A Mature Galaxy Cluster

The JWST found a galaxy cluster from 10 billion years ago that's far more developed than it should be, according to cosmological models. The cluster is also the most distant strong gravitational lens that we know of. Detailed observations across the spectrum show that the cluster is still undergoing mergers.



Are Asteroid-Mass Black Holes Hiding in the Cosmic Gamma-Ray Glow?

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there are another class of black holes, known as Primordial Black Holes (PBHs) that could have been created immediately after the Big Bang by matter collapsing in on it. Or that’s the theory at least. Though long theorized, we’ve never actually seen one of them, though scientists have suggested that they might account for the missing mass of the universe, which we otherwise describe as “dark matter”. But a new paper, available in pre-print on arXiv from researchers at Oakland University in Michigan and Rice University in Texas, calls that theory into question, at least for a certain type of PBH.

Making Sense Of Mars’ Tiny Moon Of Phobos

Understanding the Martian moon of Phobos’ origin hinges on decoding its interior. Japan’s Martian Moons Exploration (MMX) mission due for launch in late 2026 should help.

Using Plants, Astronauts Could Create Their Own Medicine

A new pharmaceutical production method could allow astronauts on long space missions to "grow" fresh medicines on demand using plants. The work could also bring low-cost pharmaceutical production to resource-limited areas on Earth.



Astronomers Want to Build a Swarm of Telescopes to Find LIFE

Current plans for flagship telescopes in the 2040s are focused on answering a simple question - are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.
