When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae.

Like whirlpools in the ocean, spinning black holes in space create a swirling torrent around them. However, black holes do not create eddies of wind or water. Rather, they generate disks of gas and dust heated to hundreds of millions of degrees that glow in X-ray light.

Fast radio bursts (FRBs) are among the most enigmatic and powerful events in the cosmos.

Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky.

Take a look at any galaxy in the universe through a telescope or in pictures captured by observatories and you might think you have a good idea of its shape.

Hundreds of thousands of volunteers have helped to overturn almost a century of galaxy classification, in a new study using data from the longstanding Galaxy Zoo project.

If astronomers want to learn about how supermassive black holes form, they have to start small--really small, astronomically speaking.

New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way.

In this large celestial mosaic taken by NASA's Spitzer Space Telescope, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. Some of these clusters are older than others and more evolved, making this a generational stellar portrait.

This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong.

Galaxies As Cosmic Cauldrons

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly "inefficiently".

Stellar Waltz With Dramatic Ending

Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object.

NASA's Spitzer Space Telescope has revealed that some of the universe's earliest galaxies were brighter than expected.

Blue supergiants are rock-and-roll: they live fast and die young.

The wavelength range of this image stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.

Astronomers have discovered a star in the Milky Way Galaxy with a chemical composition unlike any other star in our galaxy.

Hubble's measurements of today's expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13 billion years ago.

An international team of astronomers, including faculty and alumni from UNLV, has discovered a new way to spot when collisions occur in distant galaxies between two neutron stars - incredibly dense, city-sized celestial bodies that possess the most powerful magnetic fields in the universe.

Hubble Peers At Cosmic Blue Bauble

Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all.

The National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) is set to resume its hunt for gravitational waves -- ripples in space and time -- on April 1, after receiving a series of upgrades to its lasers, mirrors, and other components.
