How did supermassive black holes get so big, so early? They might have had a head start
Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centers. However, the JWST has revealed a foundational cosmic mystery.

Right now, the sun is far more active than predicted—and small satellites are paying the price
Last week, three tiny Australian satellites from Curtin University's Binar Space Program burned up in Earth's atmosphere. That was always going to happen. In fact, Binar means "fireball" in the Noongar language of the First ...

Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated ...
Mining old data from NASA's Voyager 2 solves several Uranus mysteries
When NASA's Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists' first—and, so far, only—close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery of new moons and rings, baffling ...
