Europe’s first MetOp Second Generation, MetOp-SG-A1, weather satellite – which hosts the Copernicus Sentinel-5 mission – has launched aboard an Ariane 6 rocket from the European spaceport in French Guiana. The rocket lifted off on 13 August at 02:37 CEST (12 August 21:37 Kourou time).
A SpaceX Falcon 9 rocket lifted off from Florida on Thursday morning (Aug. 14), carrying 28 Starlink broadband satellites into low Earth orbit.
As 'Alien: Earth' hits screens, the night sky delivers a cameo from the franchise's iconic villain.
The future captain of the Enterprise eclipses his co-stars every time he appears in "Strange New Worlds."
The moon will drift towards the Pleiades and Uranus in the early hours of Aug. 16-17.
SpaceX's Crew-11 mission delivered four astronauts to the International Space Station for NASA, aboard a Crew Dragon spacecraft.
Mars still holds the promise of being one of the first places in the solar system humanity will colonize. However, if there was evolutionarily distinct, extant life on the planet, it might sway the heart of even the most ardent Mars colonization fans. So astrobiologists are in a race against time to try to determine whether or not such life exists, before the entire planet becomes an analogue of the Earth’s biosphere, if only unintentionally, and only a shadow of the ones that exists here. A new paper from the Christopher Temby and Jan Spacek of the Agnostic Life Finder (ALF) team discusses one of the most promising ways to prove definitively that life exists on the Red Planet - finding polyelectrolyte polymers - in other words, DNA.
Advanced satellite and lidar mapping has uncovered signs that the Tintina fault in Canada's Yukon may be primed for a powerful earthquake.

SpaceX is preparing to launch a batch of 28 of its Starlink V2 Mini satellites into low Earth orbit minutes before sunrise on Thursday morning.
Astronomers are confident that the Milky Way and Andromeda galaxies will collide, merge, or at least interact with one another in the next few billion years. What will that merger look like? Both galaxies have dwarf galaxies, and astronomers want to know if their behaviour can predict the future of the merger.
Black holes appear stranger and more bewildering the more deeply scientists study them. They display complex characteristics that defy simple explanations. One such characteristic is the vibrations they emit when perturbed.
A Long March 5B rocket launched the eighth batch of satellites for China's Guowang broadband network on Wednesday (Aug. 13). It was the fourth Guowang launch in less than three weeks.
This quiz tests your knowledge of which female astronauts broke barriers and reached for the stars.
NASA's Orion spacecraft for the crewed Artemis 2 mission to fly astronauts around the moon is all fueled up and going through final preparations to ready the vehicle for stacking with its SLS rocket.
Artificial intelligence helps astronomers observe what may be the first known case of a star exploding while interacting with a black hole.
It's a 300-year reunion in our violent peek at this week's episode, 'The Shape of Time'.
Any material used as a light sail is bound by very restrictive physical requirements. It has to be extremely light , can’t melt from the energy applied to it, and must bend, but not break, from that pressure. Various research groups around the world have been working on materials they believe will meet those requirements, and a new paper from researchers at the University of Pennsylvania describes experimental testing of what they believe to be the most functional light sail material yet developed.
The numbers paint a stark picture of our orbital traffic problem. More than 11,000 active satellites currently circle Earth, with thousands more planned for launch in coming years. Even more concerning are the over 1.2 million pieces of space debris larger than one centimetre hurtling through space at incredible speeds. At those velocities, even a paint chip can damage a spacecraft, while larger debris can destroy entire satellites.
A recent discovery by a team of astronomers centres on a galaxy cluster called CHIPS 1911+4455, located an incredible 6 billion light-years from Earth. At its heart lies a supermassive black hole that has only recently "turned on”, just a thousand years ago. While that might sound like a long time, it's merely a blink of an eye in astronomical terms.
