A new reconfigurable structure could be used to make space habitats
Even some fields that seem fully settled will occasionally have breakthrough ideas that have reverberated impacts on the rest of the fields of science and technology. Mechanics is one of those relatively settled fields—it ...

Evidence of primordial black holes may be hiding in planets, or even everyday objects here on Earth
Imagine the formation of a black hole and you'll probably envision a massive star running out of fuel and collapsing in on itself. Yet the chaotic conditions of the early universe may have also allowed many small black holes ...

Interstellar objects can't hide from Vera Rubin
We have studied the skies for centuries, but we have only found two objects known to come from another star system. The first interstellar object to be confirmed was 1I/2017 U1, more commonly known as 'Oumuamua. It was discovered ...

New approach uses observed local supervoid to give expansion of the universe an extra push and solve the Hubble tension
Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one second after the Big ...
Cosmological model proposes dark matter production during pre-Big Bang inflation
As physicists continue their struggle to find and explain the origin of dark matter, the approximately 80% of the matter in the universe that we can't see and so far haven't been able to detect, researchers have now proposed ...
Observing dark matter at cosmic dawn
After almost a century of speculation, proposals and searches for dark matter, physicists now know that it currently comprises about 27% of the universe's mass-energy, with an abundance over five times that of ordinary matter ...
Astronomers investigate the evolution of a supersoft X-ray source
Using ESA's XMM-Newton satellite and NASA's Chandra spacecraft, German astronomers have observed a supersoft X-ray source designated RX J0513.9−6951. Results of the observations, published on the arXiv preprint server, ...
Investigating how the biggest galaxies in the cosmos grew so quickly before dying
Astronomers are closer than ever to working out how the biggest galaxies in the cosmos grew so quickly before dying.

An improved quantification of the intergalactic medium and cosmic filaments
Much of the mass in the universe lies not in stars or galaxies, but in the space between them, known as the intergalactic medium. It is warm and even hot, and is called the "warm-hot intergalactic medium," or WHIM. It holds ...
Webb observations explore the Westerlund 1 star cluster
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a supermassive Galactic open cluster known as Westerlund 1. Results of the observational campaign, presented in a paper published ...
Bandwidth measurements show how pulsar signals distort as they move through space
A study that sheds new light on how pulsar signals—the spinning remnants of massive stars—distort as they travel through space, published in The Astrophysical Journal, was led by Dr. Sofia Sheikh, SETI Institute researcher, ...

Astronomers discover a 'hot Neptune' in a tight orbit
A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as these form.

Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the ...
Ultrawide binary objects in the Kuiper belt may not have come from the earliest solar system, research suggests
Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary pairs of objects there are ...
Einstein predicted how gravity should work at the largest scales. And he was right, suggests new research
When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His gravitational model showed how Newtonian gravity, which had dominated astronomy and physics for more ...
