Are there different types of black holes? New method puts Einstein to the test (Image Credit: Phys.org) At the current resolution of telescopes, black holes predicted by different theories of gravity still look very similar. Future telescopes will make the differences more visible, making it possible to distinguish Einstein’s black holes from […]

Solar Orbiter provides first glimpse of the sun’s polar magnetic field in motion (Image Credit: Phys.org) The magnetic network on the solar surface leaves imprints in the chromosphere above. In images of this region taken by Solar Orbiter’s Extreme Ultraviolet Imager (EUI), these imprints appear as bright spots. This processed EUI image […]

Many mini-Neptunes once thought to be lava worlds may actually have solid surfaces (Image Credit: Phys.org) A new study finds that many “mini-Neptunes”—perhaps the most common planets in the galaxy—are under so much pressure from their heavy atmospheres that the surface is likely compressed solid.

Should we build an optical interferometer on the moon? (Image Credit: Phys.org) This image from the report shows permanently shadowed regions on the lunar South Pole. These regions could be desirable locations for an optical interferometer, though they present their own problems. Image Credit: W. M. Keck Institute for Space Studies (KISS) […]

The expansion of the universe is currently slowing down rather than accelerating, as evidence suggests that dark energy diminishes over time.

Universe’s expansion ‘is now slowing, not speeding up’: Evidence mounts that dark energy weakens over time (Image Credit: Phys.org) DESI is a state-of-the-art instrument which maps distant objects to study dark energy. Credit: Marilyn Sargent/Berkeley Lab The universe’s expansion may actually have started to slow rather than accelerating at an ever-increasing rate […]
