SpaceX is preparing to launch its latest batch of broadband internet satellites onboard its Falcon 9 rocket in a predawn Falcon 9 launch on Tuesday.
Research shows that modern disk galaxies have two overall components: a thin disk containing higher-metallicity young stars, and a thick disk containing lower-metallicity older stars. The thin disk sits inside the thick disk. Astronomers are trying to understand how these parts form and how disk galaxies evolve. To make progress, astronomers need to observe edge-on rather than face-on galaxies. They also need to observe them in the past, something that the JWST is built to do.
Astronomers have studied the globular cluster 47 Tucanae extensively, but still have many questions. It may have an intermediate mass black hole in its center like Omega Centauri is expected to have. There are reasons to believe it may be the remnant of a dwarf galaxy that was gobbled up by the Milky Way, like other GCs. Also like other GCs, its center is extraordinarily dense with stars, and astronomers aren't certain how far the cluster spreads. Individual stars in 47 Tuc are difficult to observe because they're so tightly packed in the center and because they're difficult to differentiate from field stars on its outer edges. Can the Vera Rubin Observatory help?

Brown dwarfs, also known as "failed stars," could be corrupted by dark matter and transformed into "dark dwarfs" powered by the universe's strangest stuff.
As James Gunn's Superman (2025) races into cinemas faster than a speeding bullet, we look at the planet that could have hosted his home world and why he might be older than he looks.

The search for dark matter requires all of the best models, theories, and ideas we can throw at it. A new paper from Julia Monika Koulen, Stefano Profumo, and Nolan Smyth from the University of California at Santa Cruz (UCSC) tackles the sizes and abundance of one of the more interesting dark matter candidates - primordial black holes (PBHs).
How did Earth, alone among the Solar System's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining? The answer to these questions is complex and multi-faceted, and part of the answer comes from cosmochemistry, an interdisciplinary field that examines how chemical elements are distributed.
Using the ALMA telescope, astronomers have revealed the internal structure of the first galaxies in the universe, hinting at how our cosmos took shape.
