Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.

Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.

Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.

Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds -- high-powered streams of charged particles and gases -- can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers.

Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.

An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.

If you've ever seen a shooting star, you might have seen a meteor on its way to Earth. Those that land here can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Scientists have conducted some of the most detailed analyses yet on the organic material of two meteorites.

Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.

When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers. Nearing the sun, outgassed hydrogen gave the tiny comet a kick.

Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.

Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near future, or even now.

With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they've ever been to finding an analog of Earth's 'twin.'

A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new study.

Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA.

A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.

Using ESO's Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA's Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid's composition from the expelled material.

Researchers have built and tested a bushfire safe room that exceeds current Australian standards and could keep people alive or protect valuables when evacuation is no longer an option.

In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
