At the center of the Centaurus galaxy cluster, there is a large elliptical galaxy called NGC 4696. Deeper still, there is a supermassive black hole buried within the core of this galaxy.
Caltech physicists at the Institute for Quantum Information and Matter have discovered the first 3D quantum liquid crystal.
This is a new state of matter they expect will have applications in ultrafast quantum computing, and the researchers believe this discovery is just the ‘tip of the iceberg’.
Black holes are weird: insanely dense objects that are crammed into such a small space they cause space-time to distort and the laws of physics to break down into a singularity.
For the first time, physicists have experimentally demonstrated the violation of “bilocal causality”—a concept that is related to the more standard local causality, except that it accounts for the precise way in which physical systems are initially generated
On Thursday, a Chinese Long March 7 rocket successfully lifted off from the Wenchang Satellite Launch Center, carrying the Tainzhou-1 spacecraft.
Astronomers who have been listening for signals from alien civilisations in the most intensive hunt for extraterrestrials yet have found no evidence of life in its first year in operation.
When it comes to exploring exoplanets, it may be wise to take a snorkel along. A new study, published in a paper in the journal Monthly Notices of the Royal Astronomical Society, has used a statistical model to predict that most habitable planets may be dominated by oceans spanning over 90% of their surface area.
The operators of proposed satellite mega-constellations can greatly mitigate the risk of future collisions by rapidly de-orbiting their spacecraft at the end of service.
The growing popularity of small satellites as well as the upcoming deployment of low-Earth orbit mega-constellations will likely greatly increase the amount of space junk as well as the frequency of catastrophic collisions, a study led by the United Kingdom’s University of Southampton suggests.
Astronomers have found a temperate planet a bit bigger and bulkier than Earth orbiting a small star just 40 light-years away. The newly announced world could be among the best targets to search for signs of life elsewhere in the cosmos.
A large asteroid the size of the Rock of Gibraltar has passed safely by Earth.
The object, measured to be almost a kilometre wide, came within five times the distance between the Earth and the Moon.
Swarms of cheap “CubeSats” are currently being planned by companies who want to bring wireless internet access to every corner of the globe. But there’s nothing to stop these sprawling “megaconstellations”, which would include thousands of spacecraft, from colliding with other satellites and unleashing hazardous space debris in low Earth orbit.
A squadron of miniature spacecraft has set off on an expedition to a little-known zone of Earth’s atmosphere. Riding an Atlas V rocket, they took off from Cape Canaveral in Florida at 1111 local time today, headed for the International Space Station.
Some scientists are thinking about what human space travelers will look like in the future. They might be extra-small and radiation-proof.
Forty years ago, Canadian physicist Bill Unruh made a surprising prediction regarding quantum field theory. Known as the Unruh effect, his theory predicted that an accelerating observer would be bathed in blackbody radiation, whereas an inertial observer would be exposed to none.

The Red Planet lacks a source of carbon dioxide that could transform its thin, cold atmosphere into something resembling conditions on Earth.
Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres. That’s according to a new study led by the Georgia Institute of Technology, adding to the growing evidence that Ceres retains a significant amount of water ice.
