Star and planet formation has largely been considered separate, sequential processes. But in a new study, scientists at Southwest Research Institute (SwRI) have modeled a different scenario where planets start developing early - during the final stages of stellar formation - rather than after this phase ends, as previously assumed. Among the many thousands of known exoplanets there is a la

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet. However, as published in Nature Astronomy, an international team of astronomers have found the unmistakable signature of a giant planet, called TOI-6894b, orbiting th

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of energy. But in the early 21st century, it was realized that most of the versions of reality described by string theory's equations cannot match up with observations of our own universe. In particula

An international team of scientists has published a new report that moves towards a better understanding of the behaviour of some of the heaviest particles in the universe under extreme conditions, which are similar to those just after the big bang. The paper, published in the journal Physics Reports, is signed by physicists Juan M. Torres-Rincon, from the Institute of Cosmos Sciences at the Uni

Astrophysicists have gained precious new insights into how distant "exoplanets" form and what their atmospheres can look like, after using the James Webb Telescope to image two young exoplanets in extraordinary detail. Among the headline findings were the presence of silicate clouds in one of the planet's atmospheres, and a circumplanetary disk thought to feed material that can form moons around

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry "spintronic" memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are

The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth's tallest volcanoes. A new panorama from NASA's 2001 Mars Odyssey orbiter shows one of the Red Planet's biggest volcanoes, Arsia Mons, poking through a canopy of clouds just before dawn. Arsia Mons and two other volcanoes form what is known as the Tharsis Montes, or Tharsis Mountains, which are

The Axiom-4 mission launch, the fourth private astronaut mission to the International Space Station, was canceled for a second time Tuesday after SpaceX detected a liquid oxygen leak in its Falcon 9 rocket. SpaceX announced Tuesday night in a post on X that it was "standing down" from Wednesday's launch of Axiom-4. "Standing down from tomorrow's Falcon 9 launch of Ax-4 to the spa
