Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought. While it can be relatively easy to locate worlds that orbit close to their star, planets with wider paths can be difficult to ...
Research from NASA's Curiosity rover has found evidence of a carbon cycle on ancient ...
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain ...
Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a ...

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but ...

A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest ...

A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring scientists ...

An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang and already shows a remarkably ...

Scientists have designed a 'cosmic radio' detector which could discover dark matter in 15 ...

Researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early Earth to ...

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real ...

Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. ...

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d ...

Researchers may have answered one of space science's long-running questions -- and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up ...

Astronomers are investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behavior unfold in real time offers a unique opportunity to ...

A team has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the Milky Way. Their findings suggest that the gravitational pull of ...

A new study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a ...

Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence ...

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists sought the ...

Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark ...

Despite its uniquely rich inventory of organic molecules, Saturn's largest moon, Titan, may be able to support only a minuscule amount of biomass, if life exists on the moon, according to a ...

What if we spend decades building advanced telescopes to search for life on other planets and come up emptyhanded? A recent study exploring what we can learn about life in the universe -- even if we ...

Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing ...
