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.

Galactic Archaeology

No one has yet found the first stars.

The Milky Way Galaxy Has A Clumpy Halo

The Milky Way galaxy is in the recycling business.

In a surprising discovery, astronomers using two Maunakea Observatories - W. M. Keck Observatory and Canada-France-Hawaii Telescope (CFHT) - have found a globular star cluster in the Andromeda Galaxy that contains a record-breaking low amount of metals.

The Ghost Nebula

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas - the raw material for building new stars.

Quasars are the brightest objects in the universe and among the most energetic.

At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter.

A team of astronomers at the University of Hawaii at Manoa Institute for Astronomy (IfA) has produced the world's largest three-dimensional astronomical imaging catalog of stars, galaxies and quasars.

Stars And Planets May Be Siblings

An international team of scientists has discovered planet formation in a star system younger than 500,000 years old.

Shedding Light On Star Formation

Astronomers from The University of Western Australia's node of the International Centre for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn of time to today.

Gemini South Views The Carina Nebula

NASA's James Webb Space Telescope is still more than a year from launching, but the Gemini South telescope in Chile has provided astronomers a glimpse of what the orbiting observatory should deliver.

Lithium is an ancient element that is almost as old as the universe itself. As one of the building blocks of our present-day universe though, the context of lithium observed in many celestial bodies often disaccord with predictions of classic theories.
