Universe Today
- A new study in Science Advances addresses the pressing questions about how long-duration exposure to microgravity affects the human genome.
- Despite the upcoming Bepi Colombo visit to Mercury, we need a lander mission to fully understand our solar systemβs innermost planet.
- Astronomers used decades of archival data and new radial velocity measurements to search for exoplanets around a neaby binary star, 70 Oph AB. They didn't find any, which can seem like a failure. But in this case, their work only ruled out large, Jupiter-mass planets at certain distances. There could still be Earth-sized planets there, […]
- Neutrinos come in three different flavors. A new study finds that neutrino flavor could play a significant role in whether a dying star becomes a supernova or collapses directly into a black hole.
- Years ago, astronomers spotted a strange radio formation beyond the Zone of Avoidance. The formation resembles a treble clef, a symbol in musical notation, and the nickname has stuck. Determining what created it has been difficult, but new research has revealed that the Treble Clef is a radio phoenix.
- The El Gordo supercluster is unusually large given its distance. How could such a large galaxy cluster form so quickly? The answer could be that dark matter is self-interacting in an interesting two-state way.
