Hawking’s Black Hole Theorem Confirmed Observationally for the First Time
Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease. There are certain…

With a competitive bracket contest, there was no risk of “Mooni McMoonface” being the winner. “Commander Moonikin Campos” is the official name of the manikin…
New research shows how the fundamental law of conservation of charge could break down near a black hole. Singularities, such as those at the center…
Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is…
First successful use aboard International Space Station of new technique for studying DNA repair in yeast. Researchers have developed and successfully demonstrated a novel method…
New analysis by University of Chicago astronomer finds agreement with standard model in ongoing “Hubble tension.” Our universe is expanding, but our two main ways…
Scientists offer new theory to explain the origin of monsters of the cosmos. When astronomers use telescopes to look back in time—toward objects in the…
A new paper finds more radar signals suggesting the presence of subsurface ‘lakes,’ but many are in areas too cold for water to remain liquid….
Astronomers studying stellar pairs uncover evidence that there could be many more Earth-sized planets than previously thought. Some exoplanet searches could be missing nearly half…
Why do some science instruments detect the gas on the Red Planet while others don’t? Reports of methane detections at Mars have captivated scientists and…
Mix pair is “elusive missing piece of the family picture of compact object mergers.” A long time ago, in two galaxies about 900 million light-years…
Europe’s Galileo satellite navigation constellation is set to grow. Later this year the first two out of 12 ‘Batch 3’ Galileo satellites will be launched…
The long relationships between stars and the planets around them — including the Sun and the Earth — may be even more complex than previously…
A team led by astronomers at UC Santa Barbara have confirmed the existence of an elusive new type of supernova. A worldwide team led by…
Rice team enhances models that will detect magnetospheres in distant solar systems. We can’t detect them yet, but radio signals from distant solar systems could…
Watch as the blast wave from an exploded star moves at nearly 9 million miles per hour. Astronomers captured this movement by combining data spanning…
This Hubble Space Telescope Picture of the Week depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic…
The universe contains a mind-boggling number of stars – but scientists’ best estimates may be an undercount. A NASA-funded sounding rocket is launching with an…
