Enormous structure discovered near doomed galaxy group is the longest galactic 'tail' ever seen
The 1.5-million-light-year-long gas trail was caused by a group of galaxies moving 3 million miles per hour
Long space missions take a toll on astronaut brains, study finds
Long spaceflights can cause astronauts' ventricles — cavities in the brain that hold cerebrospinal fluid — to enlarge by up to 25%. And it apparently takes years for the swelling...
Monitoring night-time cloud cover at the Muztagh-ata site
For optical astronomical observatories, the cloud coverage during night-time directly determines the available observing time (AOT) of a telescope, the most basic parameter in astronomical observations.
New keen-sighted satellite will view distant stars, assist Webb telescope
NASA's James Webb Space Telescope (JWST), the most powerful telescope ever launched into space, will soon get a new "sidekick"—a small but nimble satellite that borrows its name from a...
Watch: Assassin Zoe Saldaña works for Nicole Kidman in 'Special Ops: Lioness'
Paramount+ released the teaser for Taylor Sheridan's latest series, "Special Ops: Lioness," starring Zoe Saldaña, Nicole Kidman and Morgan Freeman.
Brain cavities that swell in space may need at least 3 years to recover
Spacing out spaceflights may benefit astronauts’ brains. While outside Earth’s atmosphere, fluid-filled chambers in the brains of astronauts tend to adapt to microgravity by expanding. But after a space mission, these structures might...
Scientists Make Best-Yet Map of Solar System's Interstellar Boundaries
Researchers have gained a new view of the journey ahead for the twin Voyager spacecraft and other probes bound on one-way trips into interstellar space
New tool 'cleans' ever-increasing satellite trails from Hubble photos
Scientists have developed a new tool that can keep Hubble Space Telescope photos free of the bright streaks caused by fast-moving satellites.
Frequent lengthy space travel takes a toll on astronauts' brains, study shows
As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years...
Research sheds light on new model of cosmological dark matter
Newcastle University researchers used insights gained from the study of ultracold atomic Bose Einstein condensates to analyze the behavior of fuzzy dark matter, a new model for cosmological dark matter...
Researchers detect elusive planets with CHEOPS
With the help of the CHEOPS space telescope an international team of European astronomers managed to clearly identify the existence of four new exoplanets. The four mini-Neptunes are smaller and...
New study further narrows the search for elusive pairs of monster black holes
Although astrophysicists have never sensed supermassive black hole binary systems, a galaxy-sized detector composed of dead stars is hot on their trail.
Inside Blue Abyss’s plan to build super-deep pools for astronauts and military bots
Ard Su VLADIMIR PLETSER stands in front of an eclectic audience—a group of people attending the Analog Astronaut Conference in Arizona. Analog astronauts are folks who simulate the lives of spacefarers, for science,...
Julianne Hough, Skylar Astin to host Tonys live pre-show
"Dancing with the Stars" alum Julianne Hough and "So Help Me Todd" star Skylar Astin are set to host "The Tony Awards: Act One," a live pre-show with exclusive content.
Repeated signals from the center of the Milky Way could be aliens saying hello, new study claims
A new search for extraterrestrial life has scientists looking inward — toward the center of our galaxy.
Brightest gamma-ray burst ever seen, the largest known explosion since Big Bang, has a unique jet structure unlike any other
The gamma-ray burst dubbed "the BOAT," or the brightest of all time, has a unique jet structure that may explain its extreme nature and why its afterglow persisted for so...
Cheops explores mysterious warm mini-Neptunes
Image: ESA’s exoplanet mission Cheops confirmed the existence of four warm exoplanets orbiting four stars in our Milky Way. These exoplanets have sizes between Earth and Neptune and orbit their stars closer than...
25 years of Copernicus
Video: 00:05:05 25 years ago, Copernicus set out to transform the way we see our planet. It is the largest environmental monitoring programme in the world. Learn more about the Copernicus...
Researchers discover chemical evidence for pair-instability supernova from a very massive first star
The first stars illuminated the Universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass...
Schools, museums, libraries can apply to receive artifacts from NASA
NASA is giving STEM programs across the country the opportunity to receive historical objects from the agency to be used for educational purposes.
Turkish lira plummets as Erdogan reshuffles Cabinet
Turkey's lira plummeted more than 7% to record lows Wednesday in a second massive sell-off since President Recep Tayyip Erdogan was re-elected last month.
Earth's highest, coldest, rarest clouds are back. How to see the eerie 'noctilucent clouds' this summer.
Look North as the stars appear in June and July to have a chance of seeing rare noctilucent (or 'night-shining') clouds with the naked eye.
Dying stars build humongous 'cocoons' that shake the fabric of space-time
New simulations show that dying stars release enormous "cocoons" of gas that may rattle with space-time ripples called gravitational waves.
Astronomers observe giant tails of helium escaping Jupiter-like planet
A team of astronomers has used observations from the Hobby-Eberly Telescope (HET) at The University of Texas at Austin's McDonald Observatory to discover some of the longest tails of gas...
Twenty years of Mars Express images help build mosaic of the red planet
The Mars Express orbiter, the European Space Agency's (ESA) first interplanetary mission, entered orbit around Mars on June 2nd, 2003. Since then, the probe has mapped the Martian surface using...
Gravitational waves innovation could help unlock cosmic secrets
New frontiers in the study of the universe—and gravitational waves—have been opened up following a breakthrough by University of the West of Scotland (UWS) researchers.
Gemini North back on sky with dazzling image of supernova in the Pinwheel Galaxy
The Gemini North telescope, one half of the International Gemini Observatory operated by NSF's NOIRLab, has returned from a seven-month hiatus literally with a bang, as it has captured the...
