Newton’s law describes gravity on cosmological scales, galaxy clusters reveal

Observations appear to rule out MOND, but not everyone agrees The post Newton’s law describes gravity on cosmological scales, galaxy clusters reveal appeared first on Physics World...

Medieval Japanese poetry and buried trees help elucidate volatile space weather

On Earth, extreme solar activity often appears as beautiful, benign auroras. But venturing beyond the safety of the Earth's magnetic field, one faces the full brunt of a temperamen...

This Tiny World in the Outer Solar System Should Be Airless, but It Has an Atmosphere

A tiny world in our Solar System has an atmosphere it shouldn’t—hinting something dramatic happened there recently. A group of Japanese astronomers, including both professionals an...

NASA’s Artemis moon missions are a game changer for astronomy

After decades of planning, NASA’s Artemis program is giving astronomers their long-awaited moonshot

Nearby Super-Earth Has No Atmosphere and a Dark, Moon-like Surface

The James Webb Space Telescope has observed the surface of a bare rocky exoplanet, revealing old, dark rock akin to that on our Moon. The post Nearby Super-Earth Has No Atmospher...

Indigenous Australians were the world's first astronomers. But their knowledge is now at risk

I'm a proud Yorta Yorta and Barapa Barapa man, an Indigenous astronomer and a trainee ecologist. When I look at the night sky, I don't just see stars. Instead, I see an ancient kno...

The most pristine star yet found in the known universe

An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to...

A New Era of Exploring the Universe in Radio

With 263 antennas spread across the U.S. and Mexico, the Next Generation Very Large Array, would join a new wave of radio astronomy.

In Louisville, one naturalist connects stargazing, science and conservation

Dan Price, a NASA solar system ambassador and volunteer naturalist at Bernheim Forest and Arboretum, discusses how dark skies connect astronomy, bird migration and the possibility...

The universe hidden in ink: A 2,000-year-old lost map of the night sky is coming back into recognition hidden in ancient...

Extragalactic Archaeology tells the 'life story' of a whole galaxy

Explore the Night Sky with OsmAnd Astronomy

Far from city lights, the sky looks different. In the Namib Desert, darkness comes quickly and the stars appear all at once, filling the entire horizon. At first, it feels simple....

This Alien Planet Has Rock Clouds That Vaporize Before Sunset

JWST has revealed a surprising daily cloud cycle on a distant hot Jupiter, giving scientists a clearer look at its atmosphere. On WASP-94A b, the forecast changes fast. Clouds made...

From sunsets to the night sky: How technology can help you to notice nature in new ways

On a chilly yet beautifully clear evening last November, I sat on a video call with colleagues and happened to mention the live feed from the International Space Station—a real-t...

Antarctic telescope spies alien worlds with ever-shifting orbits

JWST hunts for an 'Earth-moon' twin in a habitable zone, but the star has other plans

The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have...

Astronomers Observe the Most Chemically Primitive Galaxy in the Early Universe

An international team led by Associate Professor Kimihiko Nakajima of Kanazawa University has captured a rare look at the early universe. Using the James Webb Space Telescope (JWST...

Astronomers de-fog exoplanet atmospheres with new cloud-detecting method

Sand clouds form every morning but clear up by nightfall on WASP-94A b, a well-studied gas giant in a constellation located nearly 700 light years away from Earth. Using data from...

Asteroid named after Nijmegen amateur astronomer

An asteroid orbiting between Mars and Jupiter has been named after Astrid Eeuwes, a 45-year-old amateur astronomer from Nijmegen who...

Chang'e-5 regolith studies reveal nanoscale space-weathering processes

On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and rain, wind, and most erosion allows the lunar regolith...
