Galactic superwinds may help galaxies leak ionizing radiation, Haro 11 study finds
Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism enabling galaxies to leak ionizing radiation, which is believed to have played a major role in the ...
Hubble captures a star's swan song in planetary nebula Kohoutek 4-55
The swirling, paint-like clouds in the darkness of space in this stunning image seem surreal, like a portal to another world opening up before us. In fact, the subject of this NASA/ESA Hubble Space Telescope image is very ...

From boring to bursting: A giant black hole awakens
Although we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast to the popular idea of black ...

X-ray binary 4U 1907+09: NuSTAR observations reveal flux variability and spin-down
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have performed X-ray observations of an X-ray binary designated 4U 1907+09. Results of the observational campaign, published April 3 on the arXiv ...
Energy densities offer new path to resolving the Hubble tension
Researchers from the University of Waterloo have proposed a new method to measure the Hubble constant that could help resolve one of modern cosmology's pressing puzzles: the Hubble tension.
Our understanding of the physical properties of galaxies could be wrong
Up until recently, astronomy was reliant entirely on electromagnetic waves. While that changed with the confirmation of gravitational waves in 2016, astronomers had developed fundamental frameworks in the electromagnetic ...

Supermassive black holes could strip stars down to their helium cores
We all know that black holes can devour stars, rip them apart and consume their remnants. But that only happens if a star passes too close to a black hole. What if a star gets close enough to a star to experience strong tidal ...

This star might have been thrown out of a globular cluster by an intermediate mass black hole
Black holes come in a range of sizes. Stellar mass black holes form from the collapse of massive stars, typically weighing between 5 and 100 times the mass of our sun, and are scattered throughout galaxies. At the other extreme ...
