hello! i've got some GROUNDBREAKING space news for you!
scientists have uncovered evidence for a gravitational wave background (GWB) in our universe, and the way they went about it is fascinating.
To fully understand what's going on here, we need to go into a bit of background information.
First of all: what are gravitational waves? gravitational waves are often called 'ripples' in spacetime, often caused by extremely energetic processes such as black holes colliding, or two neutron stars orbiting each other closely.
So, how did scientists figure this out? They used 67 pulsars (known as the Pulsar Timing Array) throughout the Milky Way, practically creating a galaxy-sized telescope in order to study this.
Pulsars are the extremely dense cores of massive stars, left over after they go supernova. These are fascinating on their own, but for this project, they had an essential feature: Pulsars rapidly rotate (think up to hundreds of rotations per second), spewing radiation out in pulses from their magnetic poles. For some pulsars, these radiation jets cross Earth's line of sight, and we get incredibly constant bursts of radio signals, which can be catalogued and used as a sort of standard, universal clock.
Here is a link to a gif showing the rotation of a pulsar. Please be warned for flashing and eyestrain.
For 15 years, a team of astronomers working for the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), used radio telescopes around the globe to track minuscule changes in the signal patterns from pulsars. The changes they found are due to the slight movement of spacetime between us and the pulsars, stretching and compressing the paths of their radio waves as extremely low frequency gravitational waves pass through the universe (yes, that includes you. your atoms, as well as the atoms making up everything around you, are very slowly shifting position, dancing along to the heartbeat of the universe).

At the moment, scientists are still debating what could have caused this gravitational wave background, but some there are some leading theories: the GWB could be caused by trillions of binary black hole systems (black holes orbiting each other) throughout the universe. It could also be due to cosmic inflation, or even the big bang itself. Scientists just don't know yet, but the opportunities this discovery opens up are incredible.
The knowledge of the GWB could help us better understand the formation of early galaxies, or even help us understand the origin of the universe.

Get your online privacy under control with the best in the business. The Space, Astronomy & Science Podcast. SpaceTime Series 27 Episode 33 *The Black Hole that Ripped Apart a Star In a cosmic display of destruction, astronomers have witnessed the closest recorded incident of a star being devoured by a supermassive black hole. The event, spotted in galaxy NGC 3799, was observed in visible light, offering unprecedented insights into these violent phenomena. The tidal disruption event, now cataloged as Assassin 23 BD, emitted less energy and faded more rapidly than typical cases, placing it in a unique classification and suggesting such occurrences may be more common than once thought. *Hunting New Physics in Neutron Star Wrecks The cataclysmic mergers of neutron stars could be hiding secrets of new physics, with potential clues about the enigmatic dark matter. The historic GW170817 collision, which sent ripples through space-time, has now been used to constrain theories on axion-like particles. These elusive entities could be part of the dark matter puzzle, and their traces might be detectable in future neutron star mergers, offering a new window into the fundamental workings of the universe. *Guardian Gas Giants and Their Terrestrial Charges A new study suggests that Earth-like planets often come with Jupiter-like protectors. Simulations of planetary systems show that "dry" super-Earths and distant "cold" Jupiters frequently coexist, with the gas giants acting as cosmic shields. This relationship hints at a formation pattern where massive protoplanetary disks give rise to both rocky worlds and their gaseous sentinels, providing a glimpse into the architecture of alien solar systems. *China's Moonwalk Ambitions by 2030 China has set its sights on the Moon, with plans to land taikonauts on the lunar surface before the end of the decade. The ambitious project involves the development of the Long March 10 rocket, a new spacecraft, and a lunar lander. In a two-launch scenario, the vehicles will rendezvous in lunar orbit, setting the stage for China's historic manned moon landing and furthering their collaboration with Russia on a lunar base. Plus, we examine the latest space news, delve into the science of extreme heat and preterm births, and explore the mystery of microplastics in human arteries.

What’s a Cosmic String?
Nowadays, we have telescopes that detect not just light, but gravitational waves. We’ve already learned quite a bit about astrophysics from these telescopes. They observe ripples coming from colliding black holes, giving us a better idea of what kinds of black holes exist in the universe. But the coolest thing a gravitational wave telescope could discover is something that hasn’t been seen yet: a…
