Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe.

The spiral-shaped disc of stars and planets is being pulled, twisted and deformed with extreme violence by the gravitational force of a smaller galaxy - the Large Magellanic Cloud (LMC).

Milky Way Family Tree

Galaxies like the Milky Way formed by the merging of smaller progenitor galaxies.

Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the Sun will produce over its entire 10-billion-year lifetime.

Although astronomers have been studying galaxy IC 5063 for decades, it took a non-scientist to make the surprising discovery.

Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material within the past two decades or so. The scientists compared data from VLASS with data from an earlier survey that also used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to reach their conclusion.

In 2004, scientists with NASA's Galaxy Evolution Explorer spotted an object unlike any they'd seen in our Milky Way Galaxy: a large, faint blob of gas that seemed to have a star at its center.

Cosmic Flashes Come In All Different Sizes

On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes.

Theories on how the Milky Way formed are set to be rewritten following discoveries about the behaviour of some of its oldest stars.

How hot is the Universe today? How hot was it before?

For galaxies, as for people, living in a crowd is different from living alone.

A Cosmic Amethyst in a Dying Star

On Earth, amethysts can form when gas bubbles in lava cool under the right conditions. In space, a dying star with a mass similar to the Sun is capable of producing a structure on par with the appeal of these beautiful gems.

Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the sun will produce over its entire 10-billion-year lifetime.

Fast radio bursts, or FRBs - powerful, millisecond-duration radio waves coming from deep space outside the Milky Way Galaxy - have been among the most mysterious astronomical phenomena ever observed.

The universe would be a pretty boring place without stars. Without them, the universe would remain a diffuse plasma of mostly hydrogen and helium from the big bang.

Even if a black hole can be described with a mathematical model, it doesn't mean it exists in reality.

The Sloan Digital Sky Survey's fifth generation collected its very first observations of the cosmos at 1:47 a.m. on October 24, 2020.

Our Milky Way galaxy is shaped like two fried eggs glued back-to-back.

A More Accurate Model Of The Universe

Light from distant galaxies reveals important information about the nature of the universe and allows scientists to develop high-precision models of the history, evolution and structure of the cosmos.

No one has yet found the first stars.
