Capturing the cosmic ‘drift’ before a star is born

Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of star formation, advanced radio telescopes have given researchers new insights into the inner workings of infant stars.

Observing oscillations, flares and tornados on the sun

For six and a half days in July 2024, the balloon-borne solar observatory Sunrise III kept its gaze fixed on the sun. The stratospheric flight, which stretched from the northernmost tip of Sweden to Canada’s Northwest Territories, yielded a treasure trove of data exceeding 200 terabytes. These observations are unique. They provide insights—unprecedented in detail—into […]

A ‘smart ruler’ could help swarms of space telescopes image exoplanets

We’ve talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we’re not sending them 500-plus AU away to a gravitational lensing point. We’ve also talked at length about the potential solution to that problem—interferometry, where multiple smaller satellites […]

The ghost in Orion’s shell: Hydrogen maps show repeated stellar feedback sculpted around Orion Nebula

An international team led by Juan Diego Soler at the University of Vienna used two of the world’s most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest maps ever made of neutral hydrogen in that region of massive star formation. The findings expose the complex relationship […]

Newborn stars preserve organic-rich gas within ancient supernova debris

For the first time, astronomers have discovered stellar cocoons rich in complex organic molecules within a supernova remnant. A research team from Niigata University, Gifu University, RIKEN and Kyoto University in Japan used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe the remnant of a massive star that exploded about 1,600 years ago.

Young giant gas planet Beta Pic B refuses to reveal its origin

The young planetary system of the 23-million-year-old star Beta Pictoris (short: Beta Pic) is regarded as an iconic circumstellar dust disk, which hosts at least three giant gas planets. Discovered in 2008 by direct imaging, Beta Pic b is the most massive of those planets, measuring approximately 11 Jupiter masses. It orbits its host star […]

Primordial mini-moons may explain meteorite composition

A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within the parent bodies of the most common meteorites? The work is published in the journal Science Advances.

Scientists discover rare ‘super-Jupiter’ planet with 180-day long orbit

Scientists from Queen’s University Belfast have led an international team in the discovery of a rare new planet, which is larger than Jupiter and orbits a distant star every 180 days. Named NGTS-38 b, it is an exoplanet—a planet that orbits a star beyond our solar system. It is about 8% larger than Jupiter and […]

Astronomers dig deep to find tiny dangerous space debris

In a new study, published in the Journal of the Astronautical Sciences, Warwick researchers led an international effort to uncover some of the faintest debris in geosynchronous orbit ever observed, finding fragments as small as 5 centimeters (2 inches) and obtaining valuable data to characterize their behavior.

Unraveling a long-standing solar mystery: The extreme thinness of the sun’s tachocline layer

Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun’s tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions of high-energy particles and radiation from the sun known as “space weather.”

Astronomers build a one-stop universe data hub

Astronomers spend much of their time mapping the universe, but until now their results have been collected and archived in so many different ways that the data can’t talk to each other.

From the lab to the moon: Lunar cement alternative survives 6 months on ISS and returned stronger in some tests

Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
