Proportionality

Uranus and Neptune might have deep water oceans beneath their thick atmospheres, with a carbon layer below them. Like oil and water, the two layers never mix. The post Are Uranus and Neptune hiding oceans of water? first appeared on EarthSky.

The unexpected discovery of a geometric phase shows how math and physics are tightly intertwined

A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe evolved.

Observations from the Event Horizon Telescope may reveal a secret merger in our supermassive black hole's past, potentially explaining the cosmic monster's unusual spin.

One of the most revolutionary scientific laws was first put forth by Isaac Newton way back the in 17th century: the law of universal gravitation. Very simply, it hypothesized that between any and all…

By measuring the motions of stars in the Draco dwarf galaxy, the Hubble Space Telescope was able to map the density profile of dark matter.

Stephen Hawking suggested black holes "leak " and evaporate away — scientists could use "morsels" launched from catastrophic black hole collisions to prove...

A fusion reactor in San Diego surpasses a limit on plasma density.

A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to build larger and more complex quantum processors.

Earthlings are very lucky to see the spectacle of a total solar eclipse

From scorching hot Jupiters to worlds that seem to be a little like Earth, here are 2023's most exciting exoplanet finds.

University of Chicago astronomer Wendy Freedman tells us how she's searching for an answer to the Hubble tension — a discrepancy between measurements of our universe's expansion that could threaten the dominant model of how the universe has grown since the Big Bang.

New research shows gamma-ray blasting blazars could also be belting Earth with "ghost particles," or neutrinos.

Acoustic beam shaping with high degrees of freedom is critical for ultrasound imaging, acoustic regulation, and stimulation. The ability to fully regulate the acoustic pressure profile relative to its propagation path remains to be achieved.

An independent mass measurement of Sagittarius A* suggests we have been right all along about how utterly massive this black hole is.

How did the moon form and how old is it? The most precise dating yet of Earth's largest satellite found that it is much older than previously thought.
