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.

Want to take a trip to the center of the Milky Way? Check out a new immersive, ultra-high-definition visualization.

Just as high-definition imaging is transforming home entertainment, it is also advancing how astronomers study the universe.

The center of our galaxy is a frenzy of activity. A behemoth black hole -- 4 million times as massive as the Sun -- blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently explode.

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found a pulsar speeding away from its presumed birthplace at nearly 700 miles per second, with its trail pointing directly back at the center of a shell of debris from the supernova explosion that created it

The Origin Of Heavy Elements

A research team of experts in atomic physics, nuclear fusion science, and astronomy succeeded in computing millions of highly accurate atomic data of neodymium ions in the Japan-Lithuania international collaboration.

The Cigar Galaxy (also known as M82) is famous for its extraordinary speed in making new stars, with stars being born 10 times faster than in the Milky Way.

Old Stars Live Longer Than We Thought

Towards the end of their lives some 95% of stars evolve into red giants which lose their mass via a "stellar wind". Eventually they end up as planetary nebulae, ionized gas with a central hot star, a white dwarf.

Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter.

A compilation of scientific results from The Stratospheric Observatory for Infrared Astronomy, SOFIA, reveal new clues to how stars form and galaxies evolve, and closer to understanding the environment of Europa and its subsurface ocean.

Hubble Peers into the Vast Distance

This picture showcases a gravitational lensing system called SDSS J0928+2031. Astronomers are using NASA/ESA Hubble Space Telescope observations of this type of lensing to research how stars form and evolve in distant galaxies.

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material.
