Scientists Have Detected a Faint Hint of The Background Hum of The Universe

Ever since scientists made the first detection of gravitational waves from a pair of colliding black holes in 2015, evidence has been growing that the Universe ought to be full of them.   Every massive event – every black hole or neutron star merger, every supernova – should have sent gravitational waves ringing out across … Read more

New Breakthrough Lets Scientists Track Mysterious Fast Radio Bursts in Real-Time

Located in the Okanagan Valley outside of Penticton, British Columbia, there is a massive radio observatory dedicated to observing cosmic radio phenomena. It’s called the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a cylindrical parabolic radio telescope that looks like what snowboarders would call a “half-pipe”. This array is part of the Dominion Radio Astrophysical Observatory … Read more

The Solar System Exists Inside a Giant, Mysterious Void, And We Finally Know Why

The Solar System floats in the middle of a peculiarly empty region of space. This region of low-density, high-temperature plasma, about 1,000 light-years across, is surrounded by a shell of cooler, denser neutral gas and dust. It’s called the Local Bubble, and precisely how and why it came to exist, with the Solar System floating … Read more

Don’t Freak Out if a COVID Vaccine Slightly Changes Your Period Cycle, Says Study

Women vaccinated against COVID-19 saw a slight delay in their period of almost a day compared to those who were unvaccinated, a US government-funded study said Thursday. But the number of days of bleeding was not affected, according to the research carried out on nearly 4,000 individuals and published in Obstetrics & Gynecology.   Lead … Read more

Swab Your Throat First? Rapid Tests May Need Saliva to Detect Omicron, Early Data Find

Rapid COVID-19 tests that use nose swabs alone might not pick up Omicron in the early days of infection, a new study suggests – but experts don’t agree on whether you should also swab your throat.   A small study from a group of US researchers, published Tuesday, found that rapid tests with nasal swabs didn’t detect Omicron … Read more

Astronomers Discover One of The Biggest Structures Ever Seen in The Milky Way

Roughly 13.8 billion years ago, our Universe was born in a massive explosion that gave rise to the first subatomic particles and the laws of physics as we know them. About 370,000 years later, hydrogen had formed, the building block of stars, which fuse hydrogen and helium in their interiors to create all the heavier … Read more

Astronomers Have Detected a Mysterious, Dusty Object Erratically Dimming Its Star

There are a lot of unexplained objects out there in the Universe, and astronomers have just found another one – a strange, dusty object that may be causing its host star to dim by up to 75 percent.   Often, when we see something block out the light of its star it’s an exoplanet or … Read more

The Tiny Dots in This Image Aren’t Stars or Galaxies. They’re Black Holes

The image above may look like a fairly normal picture of the night sky, but what you’re looking at is a lot more special than just glittering stars. Each of those white dots is an active supermassive black hole.   And each of those black holes is devouring material at the heart of a galaxy … Read more

Online privacy: Will 2022 be the year we start taking things seriously?

Tsunamis’ Magnetic Fields Can Be Detected Before Sea Levels Change

Seconds count when it comes to tsunami alerts, and scientists may have found a warning sign that can be detected even earlier than sea level rises: the magnetic fields created by these gigantic rushes of waves.   Even though the difference might only be a minute or two, that can save lives. Magnetic field data … Read more
