An illustration based on data form the Gaia spacecraft shows the distribution of million stars in the Milky Way, with orange and yellow hues highlighting greater stellar densities. Now, a team using Gaia data has estimated precise ages for some of these stars, pinpointing the oldest known stellar occupants.

All rights reserved. A correct, albeit less soothing, rendition might be: Emit, emit, gigantic ball of gas. Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth. They are the building blocks of galaxies, of which there are billions in the universe.

All rights reserved. The Andromeda galaxy, also known as Messier 31, shines in a newly released picture from the Zwicky Transient Facility in California. Our galaxy, the Milky Way, is destined to collide with its largest neighbor, a sparkling collection of stars called the Andromeda galaxy. This cataclysm has been foretold by well-known physics, and astronomers know that when the space dust clears, neither galaxy will look the same: Within a billion years or so of first contact, the two will merge and form a much larger, elliptical galaxy. As astronomers report in the Astrophysical Journal , the originally predicted crash date of 3. It is inevitable.

All rights reserved. Collision bound, the Milky Way and Andromeda galaxies are hurtling toward each other at , miles , kilometers an hour. It will take several billion years before their violent tango ensues, but for a preview, astrophysicists can look at this Hubble image of an actual sideswipe of galaxies called The Mice. Prognosis for our solar system: either flung safely into space—or blasted by radiation from supernovae at the center of the new galaxy. Imagine a universe with no stars, no galaxies , and no light: just a black brew of primordial gases immersed in a sea of invisible matter. Beginning a few hundred thousand years after the blinding flash of the big bang, the universe plunged into a darkness that lasted almost a half billion years.

“They are as old as the oldest stars in the universe,” astronomers report.

  1. Galaxies are sprawling systems of dust, gas, dark matter, and anywhere from a million to a trillion stars that are held together by gravity. Nearly.
