Smart surfaces face zero gravity test in boiling heat experiments

A research team led by Davoud Jafari at the University of Twente, in collaboration with the University of Pisa, has completed a series of parabolic flight experiments to investigate advanced smart surfaces under rapidly changing gravity conditions. Conducted aboard the Air Zero G aircraft operated by Novespace, the campaign integrated additive manufacturing, boiling heat transfer […]

MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk

Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational campaign, published May 27 on the pre-print server arXiv, offer new insights into how this galaxy evolved and shed more light on its nature. […]

SpaceX signs pre-IPO deal to provide AI computing to Google

SpaceX on Friday signed a blockbuster cloud computing agreement under which Google will pay the Elon Musk-founded rocket company $920 million per month for access to a massive cluster of AI chips, according to a disclosure in its initial public offering filing.

Did this star eat its planets? A new study offers clues on ‘chemical paradox’ of a binary system

Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show dramatically different chemical compositions. The new study, uploaded to the arXiv preprint server on May 29, hints at the possibility that one of the stars may have swallowed its own planets.

First steps: America’s grueling second spacewalk

One year after Gemini IV astronaut Edward H. White completed NASA’s first spacewalk the agency prepared for a demanding second excursion. Originally scheduled for Gemini VIII, the extravehicular activity (EVA) was reassigned to Gemini IX-A after that mission ended early, with Gene Cernan taking on the task.

Webb unveils young stars across every stage of formation

For this NASA/ESA/CSA James Webb Space Telescope Picture of the Month, we return to the constellation Orion (the Hunter), a location familiar to Webb. This area of the sky is replete with star-forming clouds that make up a complex hundreds of light-years across. We find ourselves in the giant molecular cloud Orion A, of which […]

Could it be aliens? From Cheyava Falls on Mars to exoplanet K2‑18b—here’s what scientists really think

It may seem like we are on the verge of discovering alien life. In 2025, a press release stated that we have the “strongest hints yet” of extraterrestrial life on the exoplanet K2-18b. And when talking about a collected sample from a rock named “Cheyava Falls” on Mars, NASA Administrator Sean Duffy said this was […]

Magnetic field helps binary star systems form, new simulations indicate

New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary protostars. These results can help explain the characteristics of the binary star systems observed in the Milky Way. The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve. […]
