SpaceX has pushed back the flight of its next Falcon 9 rocket from Tuesday to Saturday as Subtropical Storm Nicole threatens the east coast of Florida, officials said Monday. But NASA is keeping its Artemis 1 moon rocket on the launch pad at Kennedy Space Center in preparation for a launch attempt next week.
China has a new, powerful communications satellite heading to geostationary orbit after a successful launch over the weekend.
About half of the contiguous 48 states will enjoy mainly clear skies, providing a perfect backdrop for viewing the total eclipse of the moon that will take place early on Election Day morning.
All stars are composed of mostly hydrogen and helium, but most stars also have measurable amounts of heavier elements, which astronomers lump into the category of “metals.” Our Sun has more metals than most stars because the nebula from which it formed was the remnant debris of earlier stars. These were in turn children of even earlier stars, and so on. Generally, each new generation of stars has a bit more metal than the last. The very first stars, those born from the primordial hydrogen and helium of the cosmos, had almost no metal in them. We’ve never seen one of these primordial stars, but with the power of the Webb and a bit of luck, we might catch a glimpse of them soon.
A wisp of light reflecting off the moon got caught in Earth's atmosphere, making our neighbor look like a white crown in orbit.
The private Cygnus cargo ship has managed to unfurl just one of its two solar arrays, but the freighter may still be able to reach the space station on Wednesday (Nov. 9) as planned.
See the sun rise while a total lunar eclipse sets on Tuesday (Nov. 8), in a phenomenon known as a 'selenelion'.
We've assembled a chronology of the different phases of the Blood Moon total lunar eclipse, including some of the things you might see during each phase.
Someday on Europa, there’ll be a robotic explorer diving beneath its icy surface to find volcanoes. Yes, even though it’s an ice world, Europa shows signs of internal activity. Planetary scientists think volcanic features, similar to hydrothermal vents here on Earth, exist on Europa’s ocean floor. But, how to understand them?
A strange blue aurora has been spotted in the skies over Abisko, Sweden. Could a Russian submarine be the culprit of the mysterious light show?
One of the first movies from Phase 5 of the MCU we’ll be watching is the Guardians of the Galaxy Vol. 3. Here’s everything we know so far.
Estimating stellar age has always been a challenge for astronomers. Now, a certain class of exoplanets is making the process even more complicated. Hot Jupiters – gas giants with orbital periods smaller than that of Mercury – appear to have an anti-aging effect on their stars, according to a new study. These enormous planets inflict both magnetic and tidal interference on their host star, speeding up the star’s rotation and causing them to emit X-rays more energetically, both of which are hallmarks of stellar youth. The result calls into question some of what we previously believed about stellar age, and offers a glimpse at the ongoing interconnectivity between a star and its planets long after their formation.

Using its second-to-last Antares rocket with Russian engines before a redesign to rely on all-U.S. propulsion, Northrop Grumman sent a Cygnus supply ship into orbit from Virginia on Monday to deliver spacewalk equipment, experiments, and fresh treats for the crew on the International Space Station.
Planets and stars are almost like parents and children, a new study suggests: The smaller bodies keep the larger ones active, helping them stay young for longer.
A computer simulation of TRAPPIST-1e shows how the James Webb Space Telescope could help the search for habitable alien worlds.
Two puffs of star-making material exude mystical glows in a recently-published Hubble Space Telescope image.
Since February 2019, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander has been making the first-ever measurements of tectonics on another planet. The key to this is InSight’s Seismic Experiment for Interior Structure (SEIS) instrument (developed by seismologists and geophysicists at ETH Zurich), which has been on the surface listening for signs of “marsquakes.” The dataset it has gathered (over 1,300 seismic events) has largely confirmed what planetary scientists have long suspected: that Mars is largely quiet.
Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers of black holes.
The last total lunar eclipse until 2025 will turn the moon a blood-red hue on Tuesday, Nov. 8, but exactly when you should look up depends on where you are.

China launched a high-power communications satellite Saturday on a mission to connect airline passengers, maritime vessels, and other users across China, Southeast Asia, and remote routes between the Asia-Pacific region and North America.
The rapid decline of the British-Irish Ice Sheet thousands of years ago may hold lessons for how melting ice sheets in Greenland and Antarctica will influence sea-level rise in the future.
