Galaxy Evolution Can be Affected by Black Hole Jets
In recent decades, astronomers have found evidence that supermassive black holes can really mess with their galaxies' evolution. They gobble up material intended for star formation, quenching the birth of stars. Conversely, jets streaming a
To Keep GPS Constellations From Drifting, Look To The Moon
Global Positioning Systems are a key feature in everyday life for much of the world's population. Whether it's ensuring a ship delivers its goods safely, or you're able to avoid a road closure on your commute home, GPS can help. But the sys
A Buried Volcano on the Moon Hints At An Ancient Lunar Dynamo
Scientists know for certain the moon doesn't currently have a magnetosphere. But they've been debating for decades about whether it ever did. Data from both Apollo samples and orbital scientific instruments have proven divisive, and so the
New Simulations Connect the First Galaxies to the Universe We See Today
In a recent study, researchers at the international MEGATRON project used some of the most detailed simulations of the early Universe to investigate how the first stars and galaxies formed.
Chandra X-ray Observatory Drops New View of our Galaxy's Unruly Centre
The core of the Milky Way is a dense, active, messy region, dominated by a supermassive black hole called Sagittarius A* (Sgr A*) hiding at the heart of the galaxy. But Sgr A* is only a supporting actor in this stunning new image from the C
Neutrons, Rotating Black Holes, and a Galactic PeVatron at the Center of the Milky Way
Supermassive black holes generate tremendous amounts of energy through their accretion disks and jets. But they can also generate energy through the magnetic Penrose process. A new study looks at how we might observe this process through mu
Space Radiation Sparks A Biological Cascade Of Cancer
Deep space travel comes with a huge potential downside - radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. But what exactly does that mean, and is there any way to handle it other tha
X-Rays and AI Reveal How Spacecraft Heat Shields Burn in Real Time
Heat shields are undeniably one of the most important parts of any spacecraft that intends to enter an atmosphere. And the material they are made out of is absolutely critical. Improving them has been a bit of a challenge though, as typical
XRISM Makes First-Ever Detection of a Pulsar Feeding from a Companion's Stellar "Wind"
Using data from the Japan-led XRISM observatory, astronomers have directly observed a giant star's stellar wind captured by its compact companion (triggering X-ray flares) for the first time.
