A super-Earth exoplanet has been detected within the habitable zone of a nearby red dwarf star, where liquid water might exist on its surface under the right atmospheric conditions.
The theorists predict that the beginning of the end will be in about 10 billion years — less than the present age of the universe.
Saturn will be quite distinct in the Pisces constellation.
'Here today, Gorn tomorrow. I think it's now time for other scary things to take their place.'
Marvel's new superhero movie isn't the only thing featuring some of the brightest stars.
A catalog of over 2,000 exploding white dwarf vampire stars, the largest ever gathered, has provided further evidence that dark energy is weakening.
The journey to launch is picking up pace for Europe’s MetOp Second Generation weather satellite – which hosts the Copernicus Sentinel-5 as part of its instrument package. Specialists at Europe’s Spaceport in Kourou have completed the critical and hazardous task of fuelling the satellite, marking a major milestone in its final preparations for liftoff.
Objects in the Solar System can stand out for different reasons. Some of them are bright, some of them get too close to Earth for comfort, and others have incredible surface features or unusual compositions. But some objects stand out for their orbits. Those include Trans-Neptunian Objects (TNO).
Georgia State University’s Center for High Angular Resolution Astronomy (CHARA), a six-telescope interferometer, excels at studying stars. It's been observing them for 20 years and has contributed to 276 published papers. The University is celebrating its achievements so far, and underscoring how Georgia State evolved from an institution not known for research to one that's now considered a large research university.
If life is to be found elsewhere in our Solar System, astrobiologists believe it is likely to be simple (microbial) in nature. While most of our astrobiology efforts are currently focused on Mars, multiple missions will be sent to the outer Solar System in the coming years to search for possible signs of life inside Jupiter's icy moon Europa. For decades, scientists have theorized that life could exist beneath the moon's surface around hydrothermal vents located at the core-mantle boundary. Searching for possible evidence of this life is the purpose of the ESA's JUpiter ICy moons Explorer (JUICE) and NASA's Europa Clipper mission, which are currently en route to the Jupiter system.
NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission launches at 11:13 a.m. PDT (2:13 p.m. EDT) on Wednesday, July 23, 2025, atop a SpaceX Falcon 9 rocket at Space Launch Complex 4 East at Vandenberg Space Force Base in California. The TRACERS mission will study magnetic reconnection around Earth — a process in which electrically charged plasmas exchange energy in the atmosphere — to understand how the Sun’s solar wind interacts with the magnetosphere, Earth’s protective magnetic shield.

SpaceX launched twin satellites for NASA Wednesday that will study how the electrically-charged solar wind interacts with Earth’s magnetic field, creating constantly changing and occasionally dangerous “space weather” affecting satellites, electrical grids and other critical systems.
Japan's Himawari-8 and Himawari-9 satellites, designed to study weather here on Earth, have also been quietly collecting valuable data on Venus for nearly a decade, scientists recently discovered.
Purdue University's new Neil Armstrong Space Prize, named for the school's most famous astronaut-alum, will honor achievements in "space discovery, innovation and human achievement."
The Tianzhou 9 freighter arrived at China's Tiangong space station last week, packed with supplies. Watch its arrival in this video.
NASA’s TRACERS spacecraft will look at the snap of magnetic field lines at the boundary between the solar wind and Earth's magnetic field.
Beyond plans to return astronauts to the Moon for the first time since the Apollo Era, NASA and other space agencies have their sights trained on Mars, Venus, and other deep-space destinations. To accomplish this, robust power systems are needed to provide ample power for spacecraft instruments and propulsion systems, thus reducing overall transit times. To this end, NASA is considering Radioisotope Power Systems (RPS), which have been used by the agency for over 60 years, most recently with the Curiosity and Perseverance rovers on Mars and the upcoming Dragonfly mission destined for Titan.
Black holes played a critical role in the formation of the early universe. However, astronomers have been debating for a long time just how critical, as the information we had about early black holes, which exist at high red-shifts, was relatively limited. A new paper from a group of researchers led by Sophia Geris at the University of Cambridge combined several spectra from the James Webb Space Telescope (JWST) to add some context to the formation of black holes early in the universe, and found that there are plenty of smaller ones lurking around, and lending credence to the idea that black holes of all sizes contributed to the formation of our modern universe.
Astronomers have found a fascinating new world that challenges our understanding of planetary systems. Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of researchers has discovered TOI-2431 b, an Earth sized planet orbiting a nearby star just 117 light years away. What makes this discovery extraordinary isn't just the planet's size, it’s how incredibly fast it races around its star.
The interstellar medium (ISM) is the gas and dust that's spread throughout the space between stars. It's mostly hydrogen, and its density ranges from extremely diffuse regions with few atoms, to massive, dense clouds of cold molecular hydrogen that spawn stars. In between those two extremes are different types of clouds, and those clouds are anything but uniform.
A long-standing mystery about the presence of hydrogen peroxide on Jupiter's icy ocean moon Europa may be closer to being solved.
The head of the Trump administration's Golden Dome program says the technologies needed to create such an ambitious space-based missile defense system already exist.
