Gravitational waves will be mapped to unprecedented high detail when a new gravitational wave detector mission launches in 2037. This will observe black holes, neutron stars and other objects, a new study notes. The paper looks ahead to when the Laser Interferometer Space Antenna (LISA) from the European Space Agency will fly into space to … Read more
What happens when two of the largest objects in the universe collide? Simple, says a new study: They create one of the largest shock waves in the universe. Located about 730 million light-years from Earth, Abell 3667 is a galaxy cluster in chaos. Actually composed of two clusters (or groups) of galaxies colliding into one another, Abell 3667 … Read more
The Red Sea has been hiding powerful geological forces that could put communities on the coast of Egypt and Saudi Arabia at risk. The thought hit Sam Purkis like a wave, as he gazed out the window of a submarine 900 meters deep (3,000 feet) in Tiran Strait. There, in the light of the … Read more
A billion years ago, an absolutely monstrous collision of two clusters of galaxies produced a pair of shock waves of absolutely epic proportions. Today, the structures gleam brightly in radio wavelengths, so huge they could easily engulf the Milky Way galaxy’s estimated 100,000 light-year diameter, stretching up to 6.5 million light-years through intergalactic space. … Read more
In November of 2020, a freak wave came out of the blue, lifting a lonesome buoy off the coast of British Columbia 17.6 meters high (58 feet). The four-story wall of water has now been confirmed as the most extreme rogue wave ever recorded. Such an exceptional event is thought to occur only once … Read more
When Omicron started its gigantic surge across the country, many Americans took solace in data suggesting that this variant is milder than earlier versions of the coronavirus. But one urgent question is whether Omicron changes the risk of “long COVID,” a cluster of debilitating symptoms that include fatigue, headache, pain and shortness of breath that … Read more
As a record-breaking heat wave roasted the Pacific Northwest last summer, anxiety rose with the temperatures. Surveys of residents in British Columbia—where the heat in some places soared above 120 degrees Fahrenheit—suggest the disaster caused a spike in negative mental health related to climate change. The results of the surveys, recently published in The Journal of Climate Change … Read more
When gravitational waves pass over massive objects, they should create an echo that could allow us to examine objects that we can’t otherwise see, including dark matter Space 27 January 2022 By Leah Crane An illustration of gravitational waves Shutterstock The entire universe is suffused with gravitational waves, ripples in space-time caused by the motion … Read more

When Hunga Tonga-Hunga Ha‘apai, a mostly submerged volcanic cauldron in the South Pacific Ocean, exploded on 15 January, it unleashed a blast perhaps as powerful as the world’s biggest nuclear bomb, and drove tsunami waves that crashed into Pacific shorelines. But 3 hours or so before their arrival in Japan, researchers detected the waves of … Read more
