Following the successful accelerated launch of a Global Positioning System on a Falcon 9 rocket in mid-December, the U.S. Space Force, Lockheed Martin and SpaceX are preparing to launch another GPS 3 satellite on a fast tracked basis.
A never-before-flown SpaceX Falcon 9 rocket launched a batch of Starlink satellites into orbit today (April 7) from the coast of California.
A fresh analysis of a decade's worth of Hubble Space Telescope observations shows Uranus takes 17 hours, 14 minutes and 52 seconds to complete a full rotation — 28 seconds longer than the estimate provided by NASA's Voyager 2 spacecraft nearly 40 years ago.
Astronomers have discovered a remarkable star system just 150 light-years from Earth that's destined for a spectacular cosmic display. The system contains a white dwarf star drawing material from its companion star, with the pair orbiting at just 1/60th of the Earth-Sun distance. With their combined mass reaching 1.56 times that of our Sun, these stars are gradually spiralling toward each other, setting the stage for a spectacular explosion. Fortunately, scientists estimate this cataclysmic event won't occur for roughly 23 billion years, long after our own Sun will have reached the end of its life cycle.
India's POEM-4 experiment module burned up and fell into the Indian Ocean to avoid becoming space debris.
The U.S. Space Force has awarded $13.7 billion in national-security launch contracts to SpaceX, United Launch Alliance and Blue Origin for missions that will lift off between 2027 and 2032.
A bright star located in the Milky Way appears nestled in the distant galaxy NGC 5530 due to a chance alignment along the Hubble Space Telescope's line of sight.
Although astronomers have ruled out a smash-up between Earth and an asteroid known as 2024 YR4 in the year 2032, the building-sized space rock still has a chance of hitting the moon. In fact, the chances — slight as they are — have doubled in the past month.
In 23 billion years, these two white dwarf stars will collide. Then, they'll explore. Here's why scientists say this discovery is such a big deal.
Despite their name, black holes can sometimes emit radiation. A team of astronomers has recently detected a flicker of X-ray radiation from the supermassive black hole at the center of the Andromeda Galaxy. This flicker was identified using 15 years of data from the Chandra X-ray Observatory, revealing two distinct flashes in 2006 and 2013. Interestingly, these flashes coincided with bursts of neutrinos detected by the IceCube Neutrino Observatory, offering exciting new insights into the extreme conditions surrounding the black hole.
New 'Superman' trailer gives us more Krypto, a better look at the Fortress of Solitude, and a giggling robot with a familiar voice.
Terraforming Mars has been the long-term dream of colonization enthusiasts for decades. But when you start to grapple with the actual physics of what would be necessary to do so, the effort seems further and further out of reach. Depictions like those of Kim Stanley Robinson's Mars Trilogy are just wildly unrealistic regarding the sheer amount of material that must be moved to the Red Planet to achieve anything remotely resembling Earth-like conditions. That is the conclusion of an abstract presented at the 56th Lunar and Planetary Science Conference by Leszek Czechowski of the Polish Academy of Sciences.
NASA celebrated the release of its Artemis 2 crew patch by projecting the insignia's art onto the iconic Vehicle Assembly Building (VAB) in Florida.
SpaceX's Fram2 astronauts take the first X-ray images of the human body in space, with a tip-of-the-hat to the first X-ray image ever taken.
The LIFE mission would feature four space telescopes acting together to search for biosignatures on rocky planets in the habitable zones of their stars.
A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.
Extraordinarily powerful light from gamma-ray bursts might help produce heavy elements from the outer shells of dying stars.
The comet was first spotted by an amateur astronomer looking through SOHO spacecraft data.
A Russian Soyuz rocket will launch three astronauts toward the International Space Station early Tuesday morning (April 8), and you can watch the action live.
Jamming and spoofing attacks on space-based services have increased by greatly over the past few years, and technologists are racing to find ways to keep the onslaught at bay.
Europe’s space industry gathered at the European Space Agency (ESA) in the Netherlands on 3–4 April to gain insights into the future of space in Europe.
