First AI-driven telescope goes stargazing

Every night, astronomers must carefully assess changing weather, the intensity of moonlight and shifting atmospheric conditions before deciding where to point a telescope. It’s a constant balancing act designed to squeeze as much science as possible from every precious hour beneath dark skies. Now, Northwestern University, University of Chicago and Fermilab scientists have developed a […]

Surprising boiling behavior in liquids could advance future space missions

When astronauts travel deeper into space, every drop of fuel becomes critical, and keeping those fuels stable for months or even years is one of the biggest engineering challenges facing future missions. Now, University of Florida researchers have uncovered a surprising behavior in boiling liquids that could help solve that challenge.

Astronomers finally measure the full size of the largest known galaxy

Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy’s outer edge for the first time. The observations confirm it as the largest known galaxy, spanning roughly 520 kiloparsecs, or about 1.7 million light-years, and containing an estimated 3.4 trillion solar masses in stars. The paper was posted […]

Probing binary stars in the Small Magellanic Cloud with the JWST

The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy’s mass, so it’s not surprising that the stellar population affects the evolution of galaxies. In the Milky Way’s disk and bulge, stars and dead stars make […]

Risks of debris between the Earth and the moon for future exploration

Cislunar space has become the focal point of considerable interest and strategic planning because of the many proposed missions to send crews to the moon in the next decade. These include NASA’s Artemis program, China and Russia’s International Lunar Research Station (ILRS), the European Space Agency’s Argonaut program and others. The long-term goals of these […]

A thermal camera trick could let LIGO see twice as far

There’s a nice kind of irony buried in this story: One of the most sensitive instruments ever built, capable of measuring distortions smaller than the width of a proton, has been quietly held back by something as mundane as heat. And the fix, it turns out, is not some exotic new sensor but a thermal […]

Image: Starburst galaxy Centaurus A

In this July 6, 2026, image, NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden activity that shape this unusual system.

Black hole feeding frenzy ends in lingering cosmic indigestion

Black holes are often portrayed as cosmic gluttons that swallow everything that comes too close. But new observations of a dramatic black hole outburst—led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura—suggest the reality is much messier.

Ancient stardust grains were seeds for the earliest solids in the solar system

How did the first solids that made up planets, moons and asteroids form from the “hot soup” that characterized our solar system’s earliest years? New research from Caltech analyzing pieces of a meteorite has found that, just as snowflakes crystallize around grains of dust, ancient stardust grains left over from long-gone suns may have been […]

Tracking satellites and space debris using radio antennae

Every year, thousands of satellites are launched into orbit around our planet. The result is an increasingly congested “space” above Earth populated by equipment that provides services to the surface. At the same time, these satellites affect ground-based astronomy and create the potential for damage when they eventually fall through Earth’s atmosphere to the surface. […]

Scientists advance space agriculture for future moon and Mars missions

Space isn’t known for rich soil or ideal agricultural conditions anywhere in the solar system. Yet amid extreme temperatures and vast distances, multidisciplinary teams at USF’s Aerospace: Science, Technology, Research and Applications Center (ASTRA) are collaborating on sustainable space agriculture projects with potential applications back on Earth.

Neptune’s inner moons may be shattered remains of ancient icy worlds

In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet’s main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA’s James Webb Space Telescope (JWST), a team of Caltech researchers has observed […]

Could quantum physics help us find Earth 2.0?

When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually between 100 million and 10 billion times fainter than its host star.

Machine learning LDL-C equation comparable to original Martin-Hopkins

A simplified machine learning-based low-density lipoprotein cholesterol (LDL-C) equation provides results that are comparable to the original Martin-Hopkins equation, according to a study published online July 15 in JAMA Cardiology.
