Update April 27, 9:30 p.m. EDT (0130 UTC): ULA confirmed deployment of the 29 Amazon Leo satellites.
HBO Max just added the Alien movie special editions to celebrate Alien Day; here are all the major differences between the theatrical & director's cuts
The ion tail appeared as Comet C/2025 R3 PanSTARRS was about 45 million miles from Earth (72 million kilometers) during its closest approach.
A SpaceX Falcon 9 rocket launched 25 Starlink internet satellites to orbit from California on Sunday (April 26). It was the company's 50th liftoff of the year already.
Telescopes are essential tools for astronomers, allowing us to capture light from distant celestial objects and study the universe. From ground-based giants to orbital observatories, these instruments have revolutionized our understanding of space.
We've already played a chunk of Owlcat Games' take on The Expanse, and it looks like the hard sci-fi Mass Effect successor we were hoping for.
Voyager 1, one of NASA’s longest continuously running interplanetary missions, had another instrument turned off last week, in an effort to keep the spacecraft operational. On April 17th, controllers turned […]
Scientists know that the behaviour of stars can dictate planetary habitability. Research shows that young stars emit powerful radiation that can strip planetary atmospheres away. And without an atmosphere, it's extremely unlikely that life could exist.
Being aware of the night sky even as you walk, even through a city, can give you a grounding in learning bright stars, constellations and how the night sky changes.
A United Launch Alliance Atlas V rocket is scheduled to launch 29 of Amazon's internet satellites tonight (April 27), and you can watch it live.
A team of scientists at the University of Virginia is using data from an instrument in Arizona to study cosmic structure and the result is the largest 3D map of the Universe ever created. The Dark Energy Spectroscopic Instrument (DESI) sits on a telescope high above the Sonoran Desert, and is one of the tools of choice to get a handle on the mystery of dark energy by charting the positions of galaxies and other objects.
The Small Magellanic Cloud, a neighbor of our Milky Way galaxy, stuns in this ambassador's picture.
What factors impact how long it takes for a supermassive black hole binary to merge?
Astrobotic completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype, marking a key milestone for the experimental propulsion technology.
AI algorithms can sharpen naturally blurry images taken by ground-based telescopes, revealing details otherwise visible only to space-borne machines like Webb and Hubble.
NASA is exploring ways to use a fleet of drones to explore the lunar south pole with an ambitious new MoonFall project.
The planet Uranus is a weird place. Not only does it roll around the Sun on its side once every 84.3 Earth years, it also sports a spindly set of rings corralled in some places by strange little moons. Two of those rings, the μ (mu) and ν (nu) rings are incredibly faint, which makes them challenging to study.

SpaceX is preparing to launch its first Falcon Heavy rocket in more than a year and a half. The Monday morning flight of the triple booster rocket from NASA’s Kennedy Space Center will feature the landing of the two side boosters at Cape Canaveral Space Force Station.
Imagine holding a wine glass up to a candle (of course I had to pour a glass to try this.) The curved glass bends and distorts the flame, stretching it into arcs and rings of light. Now scale that up to the size of a galaxy, replace the glass with a trillion solar masses of matter, and the candle with an entire galaxy billions of light years away. What you get is one of the most beautiful and scientifically powerful phenomena in all of astronomy, a gravitational lens.
I watched Armageddon again fairly recently with Bruce Willis, oil drillers in space and an asteroid the size of Texas bearing down on Earth. Buried beneath the Hollywood chaos is a genuinely interesting question, what exactly could we do with an asteroid if we got our hands on one? As it turns out, the answer has nothing to do with blowing it up, sorry Bruce but everything to do with building a new world.
