Better assessment of stress and tailored approaches to combat it could give clinicians the tools they need to fend off lasting damage to health

A monster exoplanet as big as 10 times the size of Jupiter has emerged from the stellar gas and dust surrounding a young star, thanks to the telescope tag team of Gaia and ALMA.

UK company Superdielectrics says its polymer technology could make batteries cheaper and easier to recycle, but its energy density must improve to compete with lithium-ion devices

Illnesses from stealthy pathogens known as Vibrio are advancing northward along numerous coasts, potentially ruining your summer vacation

U.S. President Trump's "One, Big Beautiful Bill Act," H.R. 1 includes $1 billion for the U.S. Space Force (USSF) X-37B military spacecraft program.

The four astronauts of Axiom Space's latest private mission have concluded their stay aboard the International Space Station.

This AI system can analyze up to one million DNA letters at once, predicting how tiny changes in noncoding regions trigger everything from cancer to rare genetic disorders—and potentially revolutionizing personalized medicine

Super Agers author Eric Topol unpacks the rise of biological age tests—from organ clocks to immune system clocks—and how they might revolutionize early diagnosis of disease

It’s the question of the hour. On the first day of the month July 1st, the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile spotted an interstellar interloper, which would receive the official designation C/2025 N1 ATLAS or 3I/ATLAS. The ‘I’ is a rare ‘interstellar’ designation, only the third such object known of after 1I/ʻOumuamua and 2/I Borisov. But can we see it? Such a spectacle as actually seeing an interstellar comet would be a true rarity to cross off your skywatching life list.

Stars don’t form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the galaxy at almost absolute zero, emitting essentially no light, and generally making life difficult for astronomers. But, part of how they make life difficult is actually the key to studying them - they have “absorption lines” that detail what kind of material the light is passing through on its way to Earth. A new paper from Harvey Liszt of America’s National Radio Astronomy Observatory and Maryvonne Gerin of the Sorbonne details how tracking those absorption lines via radio astronomy can trace the “dark neutral medium” of interstellar gas throughout the galaxy.

A 2.35 billion year old rock that fell from the sky in Africa is rewriting our understanding of the Moon's past. This ancient meteorite, blasted off the lunar surface has revealed that our closest neighbor remained volcanically active for nearly a billion years longer than scientists previously knew. With its unique chemical fingerprint pointing to deep lunar origins, this rare space rock proves that sometimes the most extraordinary discoveries don't require billion dollar missions, they literally drop into our laps, carrying secrets from space.

Why wait for rare solar eclipses? ESA's Proba mission can now create an artificial solar eclipse once a day. Now, a UK-led mission could do the same trick, but using the Moon's shadow to provide a 48-minute total eclipse once every lunar orbit (29.6 days). Named the Moon-Enabled Sun Occultation Mission (MESOM), the small spacecraft would align its orbit with the Moon, blocking the Sun perfectly, allowing observations of the solar atmosphere.

On June 14 and 16, technicians installed solar panels onto NASA’s Nancy Grace Roman Space Telescope, one of the final steps in assembling the observatory. Collectively called the Solar Array Sun Shield, these panels will power and shade the observatory, enabling all the mission’s observations and helping keep the instruments cool. “At this point, the […]

It's crazy to think that the JWST has already been working for three years. It's repeatedly impressed us not only with its powerful science observations, but also with stunning images that capture our interest even if we didn't know what we were seeing. Now, the telescope is celebrating its third anniversary with a glorious image of the Cat's Paw Nebula.

Shortly after the Big Bang, after the CMB was released, there was a time that's tricky to observe called Cosmic Dark Ages. Clouds of hydrogen could be detected at that time using a specific frequency of radio waves, but Earth's radiation introduces too much noise. Researchers are proposing a CubeSat called Cosmo Cube that could orbit the Moon, observing when it's in the quiet radio shadow cast by the Moon. It could help detect the first structures coming together, leading to the formation of the first galaxies.

Satellite data suggests cloud darkening is responsible for much of the warming since 2001, and the good news is that it is a temporary effect due to a drop in sulphate pollution
