The arrhythmic beating of a black hole heart
25th April 2017 phys.org | Space

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.

Scientists Have Discovered a New Quantum State of Matter
25th April 2017 | sciencealert.com | Space, Tech

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’.

Physicists Say They’ve Found a Way to Detect Naked Singularities… if They Exist
25th April 2017 | sciencealert.com | Space

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.

Physicists demonstrate new way to violate local causality
25th April 2017 phys.org | Space, Tech

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

China takes a key step toward building a large space station
23rd April 2017 arstechnica.com | Space

On Thursday, a Chinese Long March 7 rocket successfully lifted off from the Wenchang Satellite Launch Center, carrying the Tainzhou-1 spacecraft.

No encounters: most ambitious alien search to date draws a blank
23rd April 2017 | theguardian.com | Space

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.

Alien Water Worlds –“Most Habitable Planets May Have Oceans Spanning 90% of Their Surface”
23rd April 2017 | dailygalaxy.com | Space

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.

Mega-constellation satellites will need ‘rapid disposal’
22nd April 2017 | bbc.com | Space

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.

Could Cubesats Trigger a Space Junk Apocalypse?
22nd April 2017 | space.com | Space

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.

New Super-Earth May Be Best Yet for Finding Signs of Life
21st April 2017 news.nationalgeographic.com | Space

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.

‘Gibraltar-sized’ space rock passes Earth
21st April 2017 | bbc.com | Space

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.

Satellite swarms could increase space junk risk by 50 per cent
21st April 2017 | newscientist.com | Space

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.

Fleet of CubeSats launches to study the neglected ‘ignorosphere’
21st April 2017 | newscientist.com | Space

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.

Engineering the Perfect Astronaut
21st April 2017 | technologyreview.com | Space

Some scientists are thinking about what human space travelers will look like in the future. They might be extra-small and radiation-proof.

Could space travelers melt as they accelerate through deep space?
21st April 2017 phys.org | Space

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.

Landslides on Ceres reflect hidden ice
20th April 2017 phys.org | Space

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.
