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.
All large galaxies are thought to host supermassive black holes (SMBH). When the black holes are actively accreting material and emitting radiation, astrophysicists call them active galactic nuclei (AGN). Some AGN emit relativistic jets, streams of ionized matter moving at near the speed of light. When those powerful jets are pointed at us, we call them blazars.
The medieval-looking "helmet" is the latest addition to Mars' gallery of odd-shaped rocks.
A new study finds that liquids other than water might be able to support life on worlds beyond Earth, potentially expanding the envelope of life throughout the cosmos.
Combining 25 years of space-based data with ocean sampling, scientists have uncovered a change in the microscopic organisms that underpin the Southern Ocean’s food chain and carbon storage.
The star, called DFK 52, is a member of a cluster of similar red supergiants, but it's losing mass at an extreme rate never seen before.
The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere.
Forecasters warn Erin may intensify into the season's first major hurricane within days.
A large simulated moonscape built by the Colorado School of Mines is open for business, allowing researchers and companies to test their ideas for lunar rovers, landing pads, mining gear and more.
