Astronomers capture close-up images of nova explosions on 2 dead stars in unprecedented detail
The nova eruptions come about when a white dwarf steals too much matter from a close red giant companion.
57 ways to capture a dying star: Astronomers get a glimpse of what will happen when our sun dies
"With ALMA, we can now see the atmosphere of a dying star with a level of clarity in a similar way to what we do for the sun."
Scientists discover cosmic ‘scar’ in interstellar clouds left by a close shave between our sun and 2 intruder stars
"It’s kind of a jigsaw puzzle where all the different pieces are moving."
Scientists capture 51 images showing exoplanets coming together around other stars: ‘This data set is an astronomical treasure’
The Very Large Telescope's SPHERE instrument captured unprecedented images of 51 dusty rings shaping young planetary systems.
Why is this star so weird? Maybe because it ate one of its own planets
Astronomers are just beginning to scratch the surface of the complex, and sometimes violent, relationships between planets and their parent stars.
Do the cores of dead stars exist forever?
Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.
Huge red giant star has newfound companion — and it may be a bad neighbor
"Throwing a close companion into the mix could possibly wreak further havoc on the already complicated processes surrounding these stars."
Astronomers spot 1st coronal mass ejection from an alien star – and that’s bad news in the search for life
"Astronomers have wanted to spot a coronal mass ejection on another star for decades. We’ve now managed to do this for the first time."
How compact can a neutron star get before collapsing into a black hole?
This new analysis could be used to test the physics of quantum chromodynamics in the future.
A doomed planet is being torn up by its ‘zombie’ white dwarf star — but astronomers don’t understand why
The destroyed planet has spewed material onto the white dwarf's surface, with astronomers detecting 13 different elements originating from the rocky body.
