Astronomers aren't always chasing kilonovas, however; sometimes, they are way ahead of these powerful flashes of light. In early 2023, astronomers saw, for the first time, what they think is a system that is destined to birth a kilonova. Thekilonova progenitor systemCPD-29 2176is located 11...

The most common radio galaxy structures are double near symmetrical elliptical lobes extending for many thousands of light years from the AGN to up ten times the width of the Milky Way, comprising the largest single structures astronomers have ever seen. These clouds of plasma — superheated ionize...
In our currentscientific era,astronomerswork with a different concept of constellations. Modern researchersdividethe night sky into88 sectorsin a process that is a bit like dividing a map of a land mass intostates. Each of these sectors is anarea of the skywithbordersthat are defined by celesti...

Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of ...

NEW YORK (AP) — Distant, ancient galaxies are giving scientists more hints that a mysterious force calleddark energymay not be what they thought. Astronomers know that the universe is being pushed apart at an accelerating rate and they have puzzled for decades ov...
With this powerful combination of techniques, astronomers are on the cusp of discovering much more about the nature of these collisions, and neutron stars, the extreme dead stars at their heart. Artist's illustration of two neutron stars colliding, generating a kilonova explosion possibly forging ...
