This image by ESA’s (European Space Agency) Euclid (with color added using ground-based images) provides an earlier snapshot of a region of our galaxy that NASA’s Nancy Grace Roman Space Telescope will repeatedly observe during the upcoming years.

NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy.

NASA’s Pegasus barge arrives at the Launch Complex 39 turn basin at the agency’s Kennedy Space Center in Florida carrying NASA’s Nancy Grace Roman Space Telescope on Sunday, June 21, 2026.

The Moon's rocky, uneven, and otherworldly surface features are highlighted by the terminator – the difference between light and darkness.

Using data from NASA’s Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy.

The aurora australis arcs over Earth during an active solar event in this photograph taken at approximately 11:32 p.m. local time from the International Space Station as it orbited 271 miles above the Indian Ocean southwest of Perth, Australia on June 5.

A period of unsettled weather brought scattered showers and thunderstorms to California’s Bay Area on May 27, 2026. That afternoon, a break in the clouds left downtown San Francisco and nearby communities beneath mostly cloud-free skies, allowing an astronaut aboard the International Space Station to take this photograph.

Easily identified by the spectacular band of dark dust that partially obscures its bright core, Messier 64, or the Black Eye Galaxy, is characterized by its bizarre internal motion.

Researchers tested soccer balls aboard the International Space Station to study how internal mass affects motion and stability in microgravity.

A train transports eight booster motor segments for the SLS (Space Launch System rocket) that will power NASA’s Artemis III mission from Northrop Grumman’s Railyard Shipping Facility in Corinne, Utah, June 2, to NASA’s Kennedy Space Center in Florida.

NASA announced the Artemis III crew on Tuesday, June 9, 2026. NASA astronaut Andre Douglas, mission specialist; ESA (European Space Agency) astronaut Luca Parmitano, pilot; NASA astronaut Randy Bresnik, commander; and NASA astronaut Frank Rubio, mission specialist, will demonstrate the Orion spacecraft's rendezvous and docking capabilities with test versions from one, or both, American commercial human landing systems in development by Blue Origin and SpaceX.

NASA’s X-59 quiet supersonic research aircraft completed its first supersonic flight Friday, June 5, 2026, marking the first time the aircraft exceeded the speed of sound in support of NASA’s Quesst mission. The milestone represents a major step in flight testing as the aircraft expands into the supersonic portion of its flight envelope.

A year after America’s first spacewalk, Gemini IX-A Eugene Cernan stepped outside his spacecraft for an ambitious extravehicular activity scheduled for 167 minutes. The challenges he faced led NASA to reevaluate plans, equipment, and training for future spacewalks.

The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight.

Charles Messier was born in Badonviller, France, on June 26, 1730, the 10th child of court bailiff Nicolas and his wife Françoise. His childhood interest in astronomy was stoked by Comet Klinkenberg-Chéseaux in 1744 and the solar eclipse of 1748, and in 1751 he moved to Paris to become an assistant at the Naval Observatory.Continue reading "June 26, 1730: The birth of Charles Messier"

Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior. The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life.

Two newly confirmed "super-puff" planets are so diffuse that they are less dense than cotton candy, despite being about the size of Jupiter. Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how some of the strangest planets in the galaxy come to exist.

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—it may have come from Earth.

Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in its earliest moments, revealing an unusual sequence of intense X-ray flashes unlike anything seen in a typical gamma-ray burst.

NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight. It also carries traces of ancient water, making it an important clue to the solar system’s mysterious past.

What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious experience.

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent life.

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story.

NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways. The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth.

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.

A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, dust-filled starburst galaxies could account for a significant fraction of the Universe’s high-energy neutrinos.

Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw material needed to make new stars.

The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power. Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth. Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiation exposure, and orbital debris.

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe’s ultimate fate.

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to spot. The effect could be especially important around M-dwarf stars, the most common stars in the Milky Way.
