New Modeling Attempts to Reconcile Modified Gravity with the Bullet Cluster
Modified gravity theories typically struggle to explain the Bullet Cluster, but new research shows that a variant of modified Newtonian dynamics may be able to reproduce its famous lensing signature.
For the first time, the Hubble Space Telescope has detected the decrease in brightness from a rocky planet passing behind its host star, offering a new perspective on the lava world TOI-2431b.
Massive stars near the center of a local starburst galaxy are blowing a bubble that may be starting to “pop.”
DPS 58: Days 3 and 4
Days 3 and 4 of the 58th Division for Planetary Sciences meeting brought insights from subsurface ice on Mars, discoveries of Neptune trojans, and stories of advocacy successes.
DPS 58: Days 1 and 2
News from the 58th meeting of the AAS Division for Planetary Sciences (DPS): discovering a new dwarf planet candidate in our solar system, cracking mysteries about Europa’s ice shell, clarifying our understanding of Titan’s hazy dunes, and much more.
These “Ice Giants” Have a Hot Secret
Astrobites reports on a possible piping-hot secret about the so-called “ice giant” planets in our solar system, Uranus and Neptune.
Supercritical accretion of black holes may drive the formation of enigmatic “little red dots.”
Most galaxies are expected to contain at least one massive black hole, but how robust is this prediction? New research uses simulations to look at which galaxies tend to have more or fewer black holes, and with what properties.
