Gravitational waves rippling from black hole merger could help test general relativity
Gravitational waves have been uncovered from a massive black hole merger that shows the resultant black hole settling into a spherical shape for the first time, helping test Einstein’s theory of general relativity.
Another Fast Radio Burst is Coming from a Hypernebula. Also, Hypernebulae are a Thing
If nothing else catches your attention in the title then surely ‘hypernebula’ does! There are some amazing processes scattered around the cosmos, of particular interest are the fast radio bursts (FRB). These brief flashes of radiation happen without warning…until now. A team in the Netherlands have identified a second FRB as coming from within a hyper nebula – a dense and highly magnetised cloud of plasma that is illuminated by a powerful but unknown source!

China launches remote-sensing satellite for Egypt (video)
China launched a remote-sensing satellite for Egypt late on Sunday (Dec. 3) as space cooperation between the two countries deepens.
This Planet is Way Too Big for its Star
Scientists love outliers. Outliers are nature’s way of telling us what its boundaries are and where its limits lie. Rather than being upset when an outlier disrupts their understanding, scientists feed on the curiosity that outliers inspire.
NASA's Mars robots back in action after 'solar conjunction'
NASA's Mars robots are back up to full speed on and around the Red Planet, after a two-week pause in commanding.
Satellite map of North America's largest glacier shows 'hidden lagoon' and other secrets
NASA has revealed a new false-color image of Alaska's Malaspina Glacier that highlights several recent findings about the massive ice mass.
What are radio galaxies?
A radio galaxy is a type of galaxy with giant regions of radio emissions that reach far beyond its visible structure. We explore them in more detail here.
DARPA-funded 'Inchworm' robots could help us build moon bases. Here's how
A maneuverable robot from Japan-based startup GITAI has made the list of technologies chosen for a lunar infrastructure development study from DARPA.
Interstellar astronauts would face years-long communication delays due to time dilation
Due to the mind-blowing distances and speeds required, interstellar travel remains a major spaceflight challenge. But new research highlights yet another hurdle: Communication blackouts.
Astronaut Mike Massimino shares advice from NASA career in new book 'Moonshot'
Former NASA astronaut Mike Massimino shares lessons learned during his career and how they can be applied in his new book, "Moonshot: A NASA Astronaut's Guide to Achieving the Impossible" out Dec. 5.
Galileo Second Generation satellites take shape
To make the future of Galileo a reality, ESA and European industry are hard at work developing ultra-precise atomic clocks, system testbeds, ground mission and ground control segments and, of course, the satellites. Airbus Defence and Space, who is building six of the Galileo Second Generation constellation satellites, presented their first flight model structure to the programme’s stakeholders last week.
'The Star Wars Holiday Special' was a disaster. This new film examines why
"The Star Wars Holiday Special" scores a new tell-all book and making-of documentary about what is widely regarded as the worst "Star Wars" spinoff in history.
Red Sprites are Best Seen from Space
Planet Earth is full of some truly awe-inspiring spectacles, but few are as intriguing as a sprite, which are officially known as a Transient Luminous Event (TLE) and consist of large-scale electric discharges that shoot upwards while occurring above the cloud tops in the Earth’s mesosphere at approximate altitudes of 50-90 km (31-56 mi). In October 2023, European Space Agency (ESA) astronaut, Dr. Andreas Mogensen, who is currently onboard the International Space Station (ISS) as Commander of the Expedition 70 mission, took an incredible image of a red sprite with the Davis camera as part of the Thor-Davis experiment and his Huginn mission.
